▼ A single-blinded, randomized controlled study was conducted, enrolling thirty-six healthy adults who had not recently participated in forearm strengthening or occupations/hobbies involving repeated forceful wrist motion. A fatiguing wrist extension exercise protocol was completed to induce delayed onset
muscle soreness (DOMS). Group one received no treatment. Group two received acupuncture (ACU). Group three received sham acupuncture (S-ACU) with non-penetrating needles. Outcomes included grip strength, visual analogue scale for
pain (VAS) and
pain pressure threshold (PPT). Skin conductance (SC), skin temperature (ST) and perfusion (BF) were recorded to quantify the sympathetic nervous system response to treatment. The ACU group showed a significant increase in ipsilateral BF and in bilateral SC. The ACU group showed a significant decrease in distal ST bilaterally. The ACU and S-ACU groups showed decreased ipsilateral proximal ST. The exercise protocol did not consistently produce DOMS. The sample size of 36 may not have yielded sufficient statistical power.

▼ Non-specific low back pain (LBP) has been associated with alterations in the biomechanical properties and muscle activities of the trunk, but it is unclear how these changes are related to the dynamic stability of the trunk. During sitting, the structures of the trunk stabilise the upper body counterbalancing external moments acting on the trunk. The aim of this research was to evaluate a range of biomechanical variables including the hip and lumbar spine joints range of motions, moments and powers the viscoelastic properties of the trunk, and the role of the muscles while a participant was performing a balancing task in sitting and to compare results between healthy and LBP subjects. A custom-made swinging chair was used to perform the balancing task. It was designed to challenge primarily the trunk and to minimise the effect of the lower limbs so that the role of the trunk could be examined in isolation. Twenty-four participants with LBP and thirty healthy participants were requested to sit on the custom-made swinging chair and to regain the balance after tilting the chair backward for 10° and 20º. Electromagnetic motion track system sensors were placed on the participants’ back, one at the sacrum level and one at the first lumbar vertebral level to measure hip and lumbar kinematics. One further sensor was placed on the chair to track its rotation, which was also the rotation of the lower limbs. Forces data were taken from a force-plate which was mounted at the bottom of the chair. Inverse dynamic equations were used to derive the muscle moment acting at the hip and lumbar spine joints using data from the force platform and the motion tracking system. Muscle power was then calculated by multiplying the muscle moment and the corresponding joint angular velocity. Trunk viscoelastic parameters were derived using a second order linear model combine trunk moment and motion. Chair motion and trial duration were used to evaluate dynamic stability and task performance, in particular, the angular displacement of the chair was fitted in an equation describing the underdamped second-order response to a step input to derive natural frequency and damping ratio and to evaluate possible differences between groups. Activities, reaction times and co-contraction of the trunk muscles were evaluated using surface electromyography (EMG). The surface electrodes were placed bilaterally on the erector spinae , rectus abdominus, external and internal oblique. Kinematic analysis showed that the hip range of motion increased whereas spine range of motion angle decreased in participants with LBP for both tilt angles (p. < 0.05). No significant differences were found in muscle moment and power between healthy and LBP subjects (p > 0.05). The duration of contraction of various trunk muscles and co-contraction were significantly longer in the LBP subjects (p < 0.05) when compared to healthy subjects, and the reaction times of the muscles were also significantly reduced in LBP subjects (p<0.05). Trunk stiffness was found increased for LBP…

▼ Subacromial impingement accounts for significant burdens on the economy and individual quality of life. The development and progression of this disorder is thought to be related to overuse; however, little is known regarding biomechanical factors such as scapular kinematics, shoulder
muscle recruitment and joint proprioception with respect to this disorder. The high degree of variability between individuals on these biomechanical measures limits our ability to make inferences behind the development of shoulder impingement. Here, biomechanical factors associated with impingement are investigated using within-subjects designs in order to reduce this inherent variability. Using modern clinical techniques, this dissertation is applicable towards treatment of shoulder impingement as well as scientific understanding of motor control and function in the presence of
pain.
This dissertation includes previously published and un-published co-authored material.

▼ Myofascial
pain syndrome (MPS) is a common, nonarticular musculoskeletal disorder, characterized by myofascial trigger points (MTrPs). The clinical detection of MTrPs has poor inter-rater reliability. Ultrasound imaging could provide reliable and objective information. Therefore, the overall purpose was to assess the attributes of ultrasound of the trapezius
muscle in patients with MPS and potential discriminative ability. Quantitative B-mode ultrasound characteristics for the healthy trapezius
muscle using blob area, count and mean echo intensity (EI) was demonstrated to provide differences between healthy and patients with regional neck
pain. 98.55% of the overall variance was explained by the median blob area, mean blob count and mean EI. These results provide robust discriminative ability using these measures between clinically apparent regional neck
pain and healthy
muscle. Subsequently, texture analysis was used to evaluate the upper trapezius muscles of healthy volunteers, and patients who fulfilled the clinical criteria of latent MTrP and active MTrP. Principal component analysis (PCA) demonstrated twelve components accounting for 92.8% of the cumulative variance. Some texture features with highest loading included: energy 45 and 135 degrees (co-occurrence direction), maximum probability 90 degrees, cluster shade 0 and 45 degrees, cluster prominence 0 degrees, dissimilarity average, difference entropy average, inverse difference, information measure 1 90 degrees, correlation 45 and 90 degrees, information measure 2 average. Based on multivariate analysis of variance (MANOVA), significant between group differences (P

▼ Background and Aims: Temporomandibular disorders are clinical conditions that often involve pain in the masticatory muscles, the temporomandibular jaw joint and/or associated structures. The association between muscle pain and muscle activity is often explained by uniform increases or decreases in motor unit activity throughout a muscle but recent evidence suggests more complex changes within a painful muscle. The general aim of this study was to determine if experimentally induced masseter muscle pain modifies temporalis muscle activity. Methods: 20 healthy participants received experimental pain through hypertonic saline (5% NaCl) infusion into the right masseter; pain intensity was maintained at 40-60/100 mm on a visual analogue scale (VAS). Standardized biting tasks were performed with an intraoral force transducer while single motor unit (SMU) activity was recorded from 2 intramuscular electrodes (right masseter and right temporalis). The tasks were repeated in 4 blocks: baseline 1, hypertonic saline infusion, isotonic saline infusion, baseline 2. Each block had 3 isometric biting tasks: a slow and a fast ramp jaw closing task and a 2 step-levels jaw closing task (2 force levels: step 1 and step 2). Results: 83 SMUs were discriminated from the temporalis and 58 from the masseter muscle. This study demonstrated that induced muscle pain in the right masseter can be associated with the activation of new SMUs and the silencing of other single motor units in the painful masseter muscle as well as in the right temporalis muscle, which did not receive noxious stimulation with the hypertonic saline. No differences between pain and no pain trials were found in thresholds and firing rates of SMUs from the temporalis muscle. Discussion and conclusion: The present findings are consistent with previous findings from the limb (Hodges and Tucker 2011; Tucker et al. 2009) and rather than supporting uniform increases or decreases in motor unit activity throughout a muscle, suggest that there is a reorganization of motor unit activity across the entire jaw motor system in experimental pain.

▼ Mechanisms underlying the development of chronic
muscle pain in humans remain unknown. Our current understanding is principally based on experimentation in animals, which has resulted in the formulation of a multitude of theories and physiological models to postulate these mechanisms in humans. The vicious cycle theory – a popularised but unsupported theory in humans – suggests that
muscle metabolites produced by static
muscle contractions stimulate group III and IV
muscle nociceptors leading to an excitation of gamma-motoneurones through a reflex mechanism. Increased gamma-motor drive causes intrafusal fibres to contract increasing
muscle spindle afferent firing. This activity in turn will raise the likelihood of activation in the pool of alpha-motorneurones projecting to the primary
muscle increasing resting
muscle tonus.
Muscle spindle afferents and postganglionic sympathetic outflow to skin and
muscle were recorded from healthy subjects using the technique of microneurography. Cardiorespiratory function (blood pressure, heart rate, and respiration) was measured non-invasively.
Muscle pain was induced using a solution of hypertonic saline tonically infused via indwelling cannulae delivered by an infusion pump. The rate of infusion was controlled to ensure subjects experienced mild to moderate
pain.
Muscle spindle afferents fail to show any change in spontaneous discharge rate in response to tonic
muscle pain contradicting the observations and conclusions from animal studies. Sympathetic outflow to skin demonstrated a transient increase followed by a sustained decrease during infusion of hypertonic saline. Sympathetic outflow to
muscle demonstrated a dichotomy of responses during
muscle pain: half of the subjects showing increasing sympathetic activity, blood pressure, and heart rate; whilst the others showed decreasing sympathetic activity, blood pressure, and heart rate. Consistent responses were seen in the same individuals when the study was reproduced in a second recording.This investigation advances our understanding of the physiological consequences tonic
pain has on sympathetic outflow and
muscle spindle afferents in the context of developing chronic
muscle pain. After undertaking experimentation in awake human subjects there is no apparent evidence to suggest that tonic
pain increases the discharge rate of spontaneously active
muscle spindle afferents to result in increased
muscle tone as proposed by the “vicious cycle” theory. There is, however, evidence of sustained changes in sympathetic outflow to
muscle and skin in response to tonic
pain that may contribute to the development of chronic
pain.

▼ The goal of this thesis was to use hip abductor fatigue to perturb those who do and do not develop pain from standing and determine changes in muscular and postural responses.
Forty young healthy participants performed two sessions of standing work for two hours each. Participants performed a side-lying leg raising exercise to fatigue prior to one of the standing sessions, the other session acted as a control. Surface electromyography (EMG) of six muscles bilaterally, motion capture of the trunk and lower limbs, and force plate data under each foot were measured continuously during each standing session. Self-reported pain and isometric hip abductor strength were assessed at discrete time points using 100 mm visual analog scales and uni-axial force transducers respectively. Participants were classified as pain developers (PDs) or non-pain developers (NPDs) based on a 10 mm threshold in low back pain scores during the control session.
PDs (16/40) reported decreases in low back pain while standing during the fatigue session (10.9 ± 11.7 mm reduction) while NPDs reported minimal changes in pain with fatigue (1.5 ± 3.9 mm increase). Decreases in trunk (1033.9 ± 528.6 %MVIC reduction in first hour) and gluteal cocontraction indices (398.8 ± 792.4 %MVIC decrease in the 15 minute block) and increases in the number of anterior-posterior centre of pressure fidgets (13.5 ± 25.4 increase in the 30 minute block) were observed in the first hour of the fatigue session in PDs. Female PDs had more posterior pelvic tilt with fatigue (3.9 ± 9.2° more posterior with fatigue from 30 to 90 minutes), distinguishing them from male PDs (7.0 ± 11.3° more anterior with fatigue from 15 to 120 minutes). Both pain groups had similar EMG frequency shifts and strength lost due to fatigue. NPDs had longer times to fatigue than PDs (NPDs: 20.1 ± 11.2 minutes; PDs: 18.7 ± 9.3 minutes; p = 0.0106).
This study provides evidence that the hip abductor musculature is likely one causative factor in the low back pain developed from standing. Also, PDs had fatiguing characteristics of persons suffering from chronic low back pain, only without any pain present.

▼ Objective: This study examined the effects of two ergonomic arm supports on bilateral
muscle activity of the upper trapezius during pipette work on laboratory workers and university faculty and students as well as participants’ perception of productivity and discomfort.
Method: A repeated measures design was conducted at each individual’s workplace. Participants (N = 7) did an 8 minute predetermined pipette task using a static ergonomic arm support, a zero gravity dynamic arm support, and no arm support, sequenced at random. Electromyography (EMG) readings of bilateral upper trapezius, as well as perceptions of discomfort and productivity were collected for each trial condition.
Results: The static condition had statistically significantly lower mean EMG
muscle activity than both the control and dynamic conditions on the dominant side. The static condition also had statistically significantly lower mean EMG
muscle activity than the dynamic condition on the nondominant side. The difference of the means between the dominant and nondominant sides was statistically significantly lower for the static condition than both the control and the dynamic conditions. There were no statistically significant differences for peak EMG
muscle activity or for perceptions of discomfort or productivity.
Conclusion: It was found that the use of a static arm support for pipette work can significantly decrease mean EMG
muscle activity of the upper trapezius of the dominant side compared to the dynamic arm support or control condition. The static condition also offered more symmetry of EMG
muscle activity during pipette work. Occupational therapists can adapt work environments to increase the efficiency of
muscle activity in the shoulders of lab scientists.

Aim: This study aimed to compare the effectiveness of the Impulse iQ® Adjusting Instrument and ischaemic compression on trigger points in pain relief and quality of life in adults presenting with non-specific neck pain.
Methodology: This study was a randomised single-blinded clinical trial which consisted of 40 participants residing in the eThekwini municipality, divided into two groups of 20 each. The participants were randomly assigned using concealed allocation to one of two treatment groups of 20 viz. Impulse iQ® Adjusting Instrument (IAI) trigger point therapy group and ischaemic compression (IC) group. Neck pain level was determined using a numerical pain rating scale (NRS). Degree of lateral flexion (LF) was determined by a cervical range of motion (CROM) goniometer. Pain pressure thresholds (PPT) were measured with a pain pressure algometer. The effect of neck pain on participants’ activities of daily living was assessed using the Canadian Memorial Chiropractic College (CMCC) Neck Disability Index (NDI). The participants’ overall perception of improvement since the initiation of treatment was assessed using the Patients Global Impression of Change (PGIC). The participants received three treatments over a two and half week period with the fourth consultation being used for the final subjective and objective measurements.
Results: Repeated measures ANOVA testing was used to examine the intra-group effect of time and the inter-group effect of treatment on the outcomes of NRS, algometer readings and CROM goniometer measurements. Profile plots were used to assess the direction and trends of the effects. An intra-group analysis revealed that, objectively and subjectively, all groups responded positively to treatment over time, with no significant time-group interaction. It was noted that there was a higher rate of improvement in IAI Group with respect to algometer readings over time; however, this difference was not statistically significant.
Conclusion: This study concluded that neither IAI nor IC is more effective than the other with respect to participants’ pain perception and CROM. However, the IAI was more effective on pain pressure threshold. Based on the results collected from this study, both therapies can used in the treatment protocols of neck pain associated with MFTPs.

Myofascial Pain Syndrome, is a common source of frustration for both healthcare practitioners and patients. It is the second most common reason for patients visiting their health care practitioner and constitutes up to 85% of the reasons for visits to pain clinics (Han and Harrison, 1997). As muscle pain is the most common work-related injury (Hubbard, 1998), it costs billions of dollars in lost revenue every year due to lost productivity (Fricton, 1990). Hong (1994), states that dry needling has been extensively studied and has been shown to decrease or even abolish myofascial pain. However post dry needling soreness is a common side effect of dry needling. Stuart (2010), states that applying kinesio tape® to a musculoskeletal injury during rehabilitation could result in a quicker recovery by allowing the body to biomechanically heal itself. Garcia-Mura et al (2009), results suggest that kinesio tape® is a method highly appropriate in the treatment of myofascial trigger points by normalising muscular function, increasing lymphatic and vascular flow, diminishing pain and aid in the correction of possible articular malalignment. The aim of this study was to determine the effects that kinesio tape® has on the trapezius trigger point one post needling, to determine whether there is an increase in the therapeutic effect of dry needling and an increased recovery time of the myofascial trigger points, with regards to changes in pressure pain threshold, pain and cervical range of motion. Participants for this study were recruited either by an advertisement which was placed on the information board of the Chiropractic Day Clinic at the University of Johannesburg as well as advertisements placed in and around the University of Johannesburg at the Doornfontein Campus. Also, many participants were made aware of this study via word of mouth from candidates already involved in the study. Thirty participants were randomly assigned into one of two groups, each consisting of 15 participants. Group A received dry needling of the trapezius trigger point one followed by the application of kinesio tape® whereas group B received dry needing of trapezius trigger point one only. Participants were treated 5 times with objective and subjective measurements taken at the 1st, 3rd and 5th visits. Objective measurements consisted of readings taken with an algometer and cervical range of motion (CROM) device. The subjective measurements consisted of the Numerical Pain Rating Scale (NPRS) and the Vernon Mior Neck Disability Index. The results of the study showed clinically and statistical significant improvements for both groups in regards to alleviating pain subjectively (Numerical Pain Rating Scale and Vernon-Mior Neck Pain and Disability Index), increasing pressure pain threshold objectively (Algometer) and increasing range of motion objectively (Cervical Range of Motion device). However group A (dry needing and kinesio tape®) showed a greater improvement in both subjective and objective measurements. Based on the…

▼ M.Tech. (Chiropractic)
Neck pain is a common and costly complaint in society and many are made to believe that their neck pain is caused by pinched nerve, compressed disk, arthritis or displaced cervical vertebrae, when in reality the pain may be solely due to referral from myofascial trigger points in overworked or traumatized muscles of their upper back and shoulders. Travel and Simons (1999) demonstrated trapezius muscle of the neck, back and shoulder as the main cause of mechanical neck pain and stiffness. The aim of this study was to compare the effects of trigger point therapy using an activator instrument versus myofascial dry needling in combination with cervical spine adjustment in the treatment of those with acute or chronic neck pain associated with active trigger point 1 (TrP 1) or trigger point 2 (TrP 2) of upper trapezius muscle, with regards to pain and disability, pressure pain threshold and cervical spine range of motion. The clinical study consisted of forty participants, from the ages of 18 and 45, randomly allocated into two groups of twenty individuals each. Potential participants were examined and accepted based on inclusion and exclusion criteria. Group 1 received activator trigger point therapy to upper trapezius TrP 1 or 2 with chiropractic adjustment to restricted segments of the cervical spine, and group 2 received myofascial dry needling of upper trapezius TrP 1 or 2 with chiropractic adjustment to restricted segments of the cervical spine. Participants were treated four times over a period of two weeks. Subjective data was collected using the Vernon-Mior Neck Pain and Disability Index and a Visual Analog Scale. Objective data was collected using an algometer to measure pressure pain threshold of trapezius TrPs muscles, and a goniometer to measure cervical spine range of motion. All data was collected at the first and third visits prior to treatment, and at the fifth visit. The statistical analysis was conducted using nonparametric tests. Friedman’s test was used to assess whether neck pain, disability, cervical spine range of motion and pressure pain threshold varied over the three time intervals. Wilcoxon Signed Ranks Pair test was used for assessment of comparability of the results in each group separately, and the Mann-Whitney U test was used for comparison of the accumulated data in the two groups.

▼ Background The lumbar paraspinal muscles are critical
to provide spine stability, maintain proper posture and assist
trunk movement. Although considerable attention has been focused on
the association between variations in paraspinal muscle morphology
and low back pain (LBP), their role in the development and
progression of LBP remains unclear. Purpose The purpose of this
doctoral work was to identify potential determinants of paraspinal
muscle asymmetry, characterize the natural progression of
age-related changes in paraspinal muscle over a 15-year period and
examine their association with LBP problems, and determine whether
paraspinal muscle size, composition and asymmetry are risk
indicators for the development of LBP. Materials and Methods
Subjects were selected from the pre-existing database of the Twin
Spine Study. Data were collected through a structured interview,
physical examination and magnetic resonance imaging (MRI).
Measurement of the multifidus and erector spinae muscle
cross-sectional area (CSA), functional CSA (FCSA) (e.g. fat-free
mass) and degree of asymmetry in size and composition was obtained
from T2-weighted axial images for 202 men at baseline and 99 men at
15-year follow-up. A novel and highly reliable thresholding
technique, allowing for the separation of muscle and fat tissue,
was developed to perform quantitative measurements of paraspinal
muscle composition. Results and Conclusions Of the factors
investigated, the few that were significantly associated with
paraspinal muscle asymmetry in cross-sectional analyses included
handedness, disc height narrowing, the amount of physical activity
performed at work and leisure and familial aggregation. Yet, with
the exception of handedness and familial aggregation, the
associations were generally inconsistent across muscles and spinal
levels and explained little of the variance in paraspinal muscle
asymmetry. Over the 15-year follow-up period, the multifidus and
erector spinae showed similar morphological changes including a
decrease in size and an increase in fatty infiltration and
asymmetry. However, no significant correlation was found between
the long-term paraspinal muscle changes and LBP history. Moreover,
multifidus and erector spinae muscle size, composition and degree
of asymmetry do not appear to be major risk factors for the
short-term (1-year) or long-term (15-year) development or prognosis
of LBP, including sciatica.

We aimed to quantify masseter muscle stiffness in patients with masticatory myofascial pain. Masseter muscle stiffness was measured by acoustic radiation force impulse (ARFI) imaging, which expresses stiffness as shear wave velocity (Vs). Muscle stiffness was 1.96 m/s (4.28 kPa) in 11 patients in Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) group Ia, 2.03 m/s (4.53 kPa) in 11 patients in RDC/TMD group Ib and 1.37 m/s (2.10 kPa) in 13 control subjects. Vs was significantly greater in groups Ia and Ib than in control (Steel–Dwass test, p <0.05). Characteristic pain intensity (CPI) became clear as an independent factor impacting Vs (partial regression coefficient = 0.625; multiple regression analysis, p < 0.05). Masseter muscles stiffness correlated with CPI (Spearman’s rank order test, p < 0.05) and was about two-fold greater in groups Ia and Ib than in healthy subjects.

Introduction: Myofascial Pain Syndrome (MPS) is a painful and prevalent muscular
condition. It is characterized by the development of Myofascial trigger points (TrPs) that are locally tender when active and which can refer pain through specific patterns to other areas of the body distal from the trigger point.
There exist many types of treatments for MPS of which dry needling is one of the most effective forms. However, a very common side-effect experienced is postneedling
soreness, which when compared to trigger point injections are more painful, with respect to both intensity and duration. Studies have shown that the exact cause
of post-needling soreness has not been clearly documented.
Action Potential Simulation (APS) Therapy operates using a direct electric current
(DC) on muscles. It stimulates action potentials that are stronger than the natural
nerve impulses. It operates on a similar principle to the gate control theory of Melzack and Wall (1988) which results in the inhibition of nociceptive signals. Stimulation by the APS unit creates a normal action potential that restores the inherent biochemical processes in the region. This low to medium frequency current (below 150 Hz) has been reported to alleviate pain, decrease inflammation, enhance blood circulation and aid in wound and bone fracture healing.
Methodology: This study was designed as a prospective, randomised, controlled
experimental investigation. Sixty subjects were randomly allocated into three equal
groups of 20 subjects each. Group One received the fanning dry needling technique;
Group Two received a combination of fanning dry needling plus APS Therapy. Group
Three was the control group in which the subjects were treated with fanning dry
needling with „Sham‟ APS Therapy.
Algometer and Numerical Pain Rating Scale 101 (NRS 101) readings were taken
immediately before and after the dry needling procedure and again at the follow-up
visit 24 hours later. Subjects used a 24-hour pain diary and the NRS 101 scale which was filled out at 3 hour intervals, to record any post-needling soreness.
Results: An intra-group analysis revealed that, objectively and subjectively, all
groups experienced some degree of post-needling soreness, which deceased
significantly over time. This decrease of pain was not significantly related to the
treatment group, and there is no evidence of the differential time effect with the
treatment. An inter-group analysis yielded no statistically significant results regarding the effectiveness of the treatments received by the patients. This could be because of the small sample size or because „„Sham‟‟ APS is not a useful intervention.
Conclusion: The results from this study revealed that all three treatment groups
responded equally in the alleviation of pain. However, the dry-needling treatment
group alone (Group One)…

▼ Dissertation submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2012.
Background: Therapeutic dry needling is an established modality for the treatment of myofascial pain, whereas limited research on Kinesiotape® exists. Kinesiotaping®
is becoming popular, with the main benefit of being non-invasive and long wearing,
thereby extending the treatment to the patient. This study aimed to determine the relative effectiveness of these two treatment modalities in patients with myofascial pain syndrome of the Trapezius muscle.
Methods: The study design was a quantitative prospective randomised clinical trial.
Fifty patients were equally and randomly allocated into either the dry needling or Kinesiotape® groups. Each patient received two treatments on separate visits to the
upper trapezius muscle. Follow-ups were scheduled two to four days after the previous visit. Subjective measures were the Visual Analog Scale (VAS) and the Neck Disability Index (NDI), whilst objective measures were pain pressure threshold (PPT) and cervical range of motion (CROM).
Results: Kinesiotape® demonstrated statistical significant treatments with the VAS (p < 0.001), NDI (p < 0.001) and PPT (p= 0.022) (95% CI). Dry needling showed
statistical improvements in VAS (p= 0.001) and NDI (p < 0.001) only. Also,
Kinesiotape® demonstrated a clinically significant improvement with the VAS when
compared to the minimal clinically important differences (MCIDs). Trends of a superior treatment effect of Kinesiotape® over dry needling was observed in the VAS and PPT groups (p= 0.155; p= 0.428). Future studies could repeat the study with larger sample sizes to determine if these trends can be validated.
Conclusion: This study demonstrated that Kinesiotape® was at least as effective as
dry needling in the treatment of Myofascial Pain Syndrome. Therefore, Kinesiotaping® is a non-invasive alternative to dry needling.
Kinesiotape® therapy resulted in a greater change in pain and disability scores than
did dry-needling trigger point therapy, implying that Kinesiotape® may be a noninvasive
alternative to dry needling.

▼ Chronic low back
pain (LBP) has reached epidemic proportions as it is one of the most prevalent and expensive health care problems in the United States. A large number of conservative care interventions are available for this syndrome; however, the efficacy of these treatments has not been demonstrated through vigorous scientific investigation. Clinicians need both valid measures and effective interventions in order to efficiently manage this population. The purpose of this dissertation was to evaluate the quality of present reviews of specific stabilization exercises for chronic LBP, estimate the strength of the relationship between common abdominal
muscle performance tests and surface electromyography activity and hip resultant joint moments (RJM), determine if these tests can detect change following core stabilization exercise training, and describe the treatment effectiveness of a specific stabilization program versus a generalized stabilization program for persons with LBP due to instability. Study 1 was a systematic review of systematic reviews of specific spinal stabilization exercises. In Study 2, surface EMG activity of the upper and lower rectus abdominis, internal oblique, and external oblique muscles was obtained, while anterior superior iliac spine movement was simultaneously detected via motion analysis. Study 3 and 4 evaluated abdominal
muscle performance in healthy participants and participants with low back
pain respectively, in which double limb lowering test (DLLT) and lower abdominal
muscle progression (LAMP) grades were determined by monitoring movement with a motion analysis system. Additionally, the Modified Oswestry Index and Visual Analog Scale were administered in Study 4. Both the DLLT and LAMP may be suitable for the examination of abdominal
muscle performance as they have moderate to good correlations with abdominal
muscle surface electromyography and hip RJM. The DLLT and LAMP do not correlate well with one another suggesting that they might measure different aspects of abdominal
muscle performance. The LAMP is more responsive than the DLLT in detecting change following general stabilization training in healthy adults. Stabilization exercises, both specific and general, are effective in decreasing
pain and disability in persons with chronic LBP, especially those with instability. These findings provide the foundation for future validation of these measures and development of interventions for persons with LBP.

▼ Osteoarthritis (OA) of the knee is one of the most common musculoskeletal conditions resulting in disability. The incidence of knee OA increases with age and will likely increase further as the population becomes more obese and less physically active. Therefore, the objectives of this thesis were 1) to observe whether self-reported disability should be obtained before or after performance-based tests, 2) to assess changes in knee pain and observe whether symptoms of depression predict worsening of knee pain, quality of life (QoL) and increased need for surgery and, 3) to examine changes in quadriceps muscle strength and knee pain after isokinetic muscle testing.
In the first study, disability was measured using the WOMAC scores. Results indicated that all WOMAC scores were significantly higher after as compared to before the completion of performance-based tests and a physiologic test (VO2Peak). Obese individuals with knee OA were significantly worse compared to non-obese individuals with knee OA on all WOMAC scores.
In the second study, the WOMAC pain subscale and VAS pain were significantly higher after as compared to before the completion of performance-based tests. The VAS ratings captured a significant increase in pain in both groups, but the WOMAC pain subscale only captured a significant change in the obese OA group. Depressive symptoms and BMI explained a significant proportion of variance in knee pain, quality of life and perceived need for surgery.
The third study indicated that isokinetic quadriceps muscle strength was significantly different between obese and non-obese individuals with knee OA and compared to a healthy control group at all angular velocities of 60°/s, 90°/s and 120°/s, with the obese OA group demonstrating the lowest peak torque at all angular velocities. However, it was only at 60°/s that the isokinetic peak torque showed a statistically significant difference between the obese and the non-obese groups with knee OA. Likewise, knee pain increased from before to after isokinetic muscle strength testing, but only at the angular velocity of 60°/s.
This thesis provides new information regarding the effect of obesity on self-reported disability, knee pain, depressive symptoms and quadriceps muscle strength in knee OA.

This study aimed to determine the difference between the standard dry needling technique versus the rapid dry needling technique with regards to which technique would provide quicker relief of symptoms, as measured by an increase in participant’s pressure tolerance and range of motion and a decrease in subjective pain. Subjectively it was seen that both groups had a statistical decrease in the participants perceived pain with the Oswestry Disability Index, the McGill’s Pain Questionnaire and the Numeral Pain Rating Scale. Both groups showed significant changes over the two time variables (pre-Treatment one and post-Treatment four) with regards to all the questionnaires. Group 2 showed the most significant change when comparing the two groups with regards to the Oswestry Disability Index and the Numeral Pain Rating Scale. From these results it is seen that subjectively all the participants felt relief with respect to their perceived pain. However, objectively the rapid dry needling technique proved to improve pain faster and more consistently throughout the treatment period over the standard intra-muscular dry needling technique. Therefore the rapid dry needling technique is more effective in treating active Gluteus medius muscle trigger points.

Myofascial pain syndrome has become a significant cause of chronic pain and disability in today‟s society. Conditions causing chronic pain can not only cause disability due to pain, but can also lead to other problems such as psychological and behavioural disturbances. Physical deconditioning can also occur due to lack of exercise because of myofascial pain (Rachlin, 1994). The aim of this study was to compare dry needling therapy and ultrasound therapy in the treatment of myofascial trigger points in order to demonstrate any superiority between the two modalities. Participants for this study were recruited by word of mouth and advertisements that were placed around the University of Johannesburg Doornfontein Campus. Thirty people participated in the trial, all of whom conformed to the specific inclusion and exclusion criteria. The participants were randomly placed into two groups. Group A received dry needling therapy, namely the fanning technique, and Group B received ultrasound therapy. Participants in Group A received one treatment per week for four weeks and subjective and objective measurements were taken at each visit. Participants in Group B received two treatments per week for three weeks and measurements were taken at visits one, three, five and seven. Subjective data was obtained through the use of the Visual Analogue Pain Scale, which measured the perception of pain of the participants. Objective data was obtained from pressure algometer readings, which measured pain pressure thresholds of participants, and through the Cervical Range Of Motion (CROM) device. The results of this study indicated that dry needling therapy and ultrasound therapy both significantly benefited participants in terms of the treatment of active myofascial trigger points. Based on the final results, both dry needling therapy and ultrasound therapy are equally effective modalities in the treatment of active myofascial trigger points, with neither modality showing superiority over the other.

This study was conducted to investigate the efficacy of Chiropractic cervicothoracic spinal adjustment therapy in the treatment of active Trapezius myofascial trigger point dysfunction. Thirty participants were recruited and placed into one of two groups. Participants were between the ages of 18 and 30 years and selected based on the inclusion criteria being met. Participants had to present with active upper Trapezius trigger points and a restriction of the cervicothoracic junction. The experimental group received a Chiropractic adjustment to the cervicothoracic junction and the control group received detuned ultrasound as their respective treatments. The participants were treated six times over a 3-week period and measurements were taken on the first, fourth and seventh visits. A case history, physical examination and cervical regional examination were conducted at the first visit. Objective measurements included pressure algometry readings of Trapezius trigger points 1 and 2 and cervical spine goniometry readings. Subjective measurements included the Vernon Mior Pain Disability Index and the Numerical Pain Rating Scale. The results were interpreted by Statcon at the University of Johannesburg. The data was analysed using the Mann Whitney test and the Friedman test. According to the tests, the experimental group improved significantly in both the objective and subjective measurements over the seven visits. The control group showed an increase in the objective measurements and a decrease in the subjective measurements over the seven visits. This was found to be statistically insignificant. This study concluded that a Chiropractic adjustment to the cervicothoracic junction is effective in the treatment of upper Trapezius trigger points

Myofascial trigger points are very common and can become a painful part of most people’s life at one time or another. According to Travell and Simons (1999), active upper trapezius myofascial trigger points are common in patients presenting with neck pain. Myofascial pain syndrome is a regional muscle disorder that is one of the most common causes of persistent pain in the head, face and neck regions (Rachlin, 2002). The PAIN®GONE pen is a device that produces a high voltage, low frequency pulse for only a brief period of time. The electrical stimulation activates endorphins in the hypothalamus which plays a role in pain relief (Puskas, 2004). The technical system of the device is clinically proven and uses Transcutaneous Electric Nerve Stimulation (TENS), based on the pain gate control theory of Melzack and Wall (1965). The purpose of this study was to determine the efficacy of treating active upper trapezius trigger points with PAIN®GONE therapy combined with cervical spine chiropractic adjustments.This study consisted of two groups, the PAIN®GONE therapy group (Group 1) with fifteen participants and the placebo PAIN®GONE therapy group (Group 2) with fifteen participants. The participants were between the ages of 18 and 40 years of age. Prior to becoming a participant of this study, individuals were assessed according to the inclusion and exclusion criteria, a case history, physical examination, cervical regional examination and upper trapezius muscle palpation to assess for upper trapezius myofascial trigger points. Treatment was applied to the cervical spine by Chiropractic adjustments, and to the upper active trapezius myofascial trigger points via PAIN®GONE therapy or placebo PAIN®GONE therapy, from which the subjective and objective data were based.Each participant was treated six times over a period of three weeks. Prior to the initiation of treatment, each participant was requested to complete a Vernon-Mior Neck Pain and Disability Index questionnaire and Numerical Pain Rating Scale. Algometer readings were obtained for the active upper trapezius myofascial trigger points. The Cervical Range of Motion (CROM) goniometer was used to obtain numerical values for the participant’s active cervical spine ranges of motion in flexion, extension, lateral flexion androtation. Both groups, received treatment to the active upper trapezius trigger points and Chiropractic adjustments to the cervical spine for a total of six treatment sessions. Both subjective and objective data readings were obtained before the 1st, 4th and 7th final consultation...

OBJECTIVE: The aim of the study was to explore whether dry needle therapy delivered to latent myofascial trigger points of the biceps brachii muscle had an immediate effect on muscle activity and strength . DESIGN: One hundred participants with latent myofascial trigger points of the biceps brachii muscle and who were suitable for the study were drawn from the community. They were al located in to either a controlor treatment group so that each group contained fifty participants . The control and treatment group were divided in such a way to ensure that the two groups were comparable with one another un terms of age and gender. The International Physical Activity Questionnaire was completed by each participant to ensure that the two groups were also comparable with one another in terms of the total amount of physical activity performed per week. The results of this study were statistically analysed by STATKON at the University of Johannesburg.

Problem Statement: Myofascial Pain Syndrome (MPS) is a painful and prevalent muscular condition that is characterized by the development of myofascial trigger points (TrP’s). These are locally tender when active and are able to refer pain through specific patterns to other areas of the body distal from the trigger point (Manga, 2008). Myofascial trigger points are a frequently overlooked and misunderstood source of the distressingly ever-present musculoskeletal aches and pains of mankind and many authors have found that the trapezius muscle is most often the muscle that has frequent myofascial trigger points (Travell and Simons, 1999). Much debate and discussion has arisen on the merits of the fanning dry needling technique compared to that of the static dry needling technique, but research evidence is very limited. Some practitioners prefer the static technique over the fanning technique as it reduces the presence and amount of post-needling soreness, as well as reduces the possibility of penetrating a blood vessel resulting in hemorrhaging. Other practitioners prefer the fanning technique as it increases the chances of locating the loci of the TrP, as well as increasing the chances of eliciting a local twitch response and possibly making this method more effective in deactivating a TrP than the static technique. Aim of Study: The aim of this study was to compare the effects of static myofascial dry needling to the effects of fanning myofascial dry needling of an active trigger point (TrP1) in the upper trapezius muscle in order to determine which of the two treatments is more effective with regards to decreasing neck pain and disability as well as increasing pressure pain threshold in patients with neck pain due to Trapezius Myofascial Pain Syndrome. Method: Forty participants underwent a general screening to determine whether they had active myofascial trigger points in the upper fibers of the trapezius muscle.

▼ Low back problems are among the most common nonfatal occupational injuries reported in the United States, and account for substantial healthcare expenditures (e.g., medical care costs) and losses to worker productivity. A strong association has been well-documented between occupational exposure to repetitive trunk motion and low back problems, particularly among workers performing manual material handling (i.e., lifting) activities. A feature of repetitive motion believed important to the development of work-related musculoskeletal disorders (MSDs), including low back problems, is a lack of within-individual, between-cycle variation of physical exposure summary measures, e.g., when observed visually, the cycle-to-cycle motion pattern appears consistent. An active literature has emerged using concepts of motor control to improve ergonomists’ understanding of physical exposure variation (i.e., motor variability) arising from individual-level mechanisms during repetitive work. Fundamentally, for any particular individual, the onset of exposure to a repetitive physical activity (i.e., task training) involves a learning process during which motor control strategies are developed to accomplish the task effectively. The cycle-to-cycle variability of motor learning metrics, such as postural and task performance summary measures, has been observed to exponentially decay during task training. From an ergonomics perspective, a temporal reduction in postural variability may lead to greater cumulative loading and physiological fatiguing of the underlying
muscle tissues (due to more consistent cycle-to-cycle movements), thus increasing MSD risk over time. However, it is not known if, or to what extent, physical task characteristics (e.g., work pace) modify the temporal behavior of motor variability during training of a repetitive occupational activity. Moreover, the relationships between motor variability, task performance, and
muscle fatigue during occupational task training are not well understood. The goal of this dissertation was to present new information concerning occupationally relevant metrics of motor learning during training of a laboratory-simulated, repetitive lifting activity. In this study, participants performed 100 repetitions (i.e., cycles) of the lifting task in each of four experimental sessions (i.e., visits) at different combinations of box load (low or high) and work pace (slow or fast). Three main observations were discussed in this dissertation: (i) participants exhibited a greater temporal reduction in the cycle-to-cycle variability of trunk postural summary measures during training of a heavier-weighted and faster-paced lifting activity (Chapter 3), which may have facilitated increases in the efficiency and repeatability of box movements (Chapter 4), (ii) the cycle-to-cycle variability of the erector spinae (back)
muscle activity summary measures increased, but the variability of the multifidus
muscle activity summary measures decreased, over time during faster-paced lifting (Chapter…

▼ Low back
pain (LBP) is a common occupational problem and continues to be the leading cause of occupational disability. Among diverse known risk factors, sitting is commonly considered as an important exposure related to LBP. Both modern living and contemporary work involve increased sedentary lifestyles, including more frequent and prolonged sitting. At present, however, the causal role of sitting on LBP development is controversial due to the contribution of several moderating factors (e.g., task demands, duration of exposures, and presence of
muscle fatigue). A few studies have assessed low back loads in seated postures, but none has investigated the effects of prolonged sitting or time-dependent variations on spinal structure and spinal loading. Adverse effects of
muscle fatigue on low back
pain are well documented, yet the specific relationship between
muscle fatigue and sitting-related low back
pain are not fully established. In addition to these fundamental limitations in our understanding of the physical consequences of sitting, there is also little evidence regarding the effects of task requirements on
muscle fatigue and spine loading. Therefore, the main objectives of this work were, in the context of sitting, to: 1) develop and evaluate a method to assess paraspinal
muscle fatigue using electrical stimulation; 2) develop and evaluate a method (model) to quantify biomechanical loads on the lumbar spine in a seated posture; and 3) quantify the effects of prolonged seated tasks on low back loads, body discomfort, and localized
muscle fatigue (LMF). The primary hypothesis was that exposure to sitting-related LBP risks is influenced by task requirements and sitting duration. A
muscle stimulation protocol was developed to measure stimulation responses in the lumbar extensors. A stimulation protocol, which included one conditioning train along with three 16-second stimulation train at 2 Hz, was recommended as appropriate to measure those muscles potentially fatigued during prolonged seated tasks. A three-dimensional, sitting-specific, fatigue-sensitive, time-dependent, electromyography (EMG)-based biomechanical model of the trunk was developed to investigate the effects of seated tasks and time-dependent variations on lumbosacral loading during sitting. Reasonable levels of correspondence were found between measured and predicted lumbosacral moments under a range of seated tasks. Lastly, the effects of prolonged sitting and psychosocial work stress on low back were quantitatively identified. Only prolonged sitting significantly increased trunk flexion angles and led to
muscle fatigue. Relatively weak correlations were found between subjective and objective measures, though the two fatigue measurement methods (based on EMG and stimulated responses) showed a good level of correspondence. Overall, this work provides a quantitative assessment of biomechanical exposures associated with seated tasks. The methods developed in this work make a contribution in terms of…

▼ Background and aims: The Pain Adaptation Model and the Vicious Cycle Theory are older theories of the effects of pain on motor activity. While some data sets are consistent with these theories, other data sets are not, and a number of new models (the Integrated Pain Adaptation Model; Theory of Motor Adaptation to Pain) have been proposed. Two of these models propose a reorganization of motor activity in pain. The aim of the present study was to determine whether experimental masseter muscle pain resulted in a change in muscle activity at two different sites within the masseter muscle during the performance of isometric jaw-closing tasks in asymptomatic participants. Methods: Single motor unit (SMU) activity was recorded with bipolar fine wire electrodes at 2 sites within the right masseter muscle during the performance of standardized isometric biting on an intraoral force transducer in 17 healthy participants. Participants performed standardized biting trials during infusion of 5% hypertonic saline into the right masseter (pain), and during isotonic saline infusion (control). Recruitment patterns, force thresholds and firing rates were compared between pain and control trials. Results: A total of 50 SMUs were discriminated from the 2 sites. Changes in recruitment patterns of SMUs at one site within the masseter muscle during pain in comparison with control was observed during the tasks and some of these changes were different to the changes occurring at the other site. There were no changes in thresholds of SMU firing nor in SMU firing rates between pain and control trials. Inter-individual variability in the motor response to pain was observed at the two different sites of the masseter. Discussion and Conclusions: In general, the data are not consistent with the earlier models of pain-motor interactions, but provide support for more recent models proposing a re-organization of motor activity in the presence of pain.

▼ Muscle capacity refers to an individual’s ability to utilize their muscle strength and power in order to efficiently and effectively complete physical activities (Brady & Straight, 2014). Muscle capacity is associated with an individual’s physical function (Brady & Straight, 2014), as it incorporates the utilization of skeletal mass during physical tasks (Woods et al., 2011). In fact, age-related declines in both muscle strength and power have been observed to influence changes in physical activity (Doherty et al., 1993; Newman et al., 2006; Woods et al., 2011). Muscle capacity plays an important role in maintaining an individual’s health and wellbeing during aging.
This study explored the relationship between pain and muscle capacity utilization during walking in older adults with knee osteoarthritis (OA). A convenience sample of 23 participants (15 females and eight males) with symptomatic knee OA completed this study [age 67 (±8) years, body mass index 29.7 (±3.9) kg/m2, gait speed 1.25 (±0.25) m/s]. Muscle capacity utilization was measured by calculating the ratio of the external peak knee flexion moment measured using gait analysis, to the maximum voluntary isometric contraction (MVIC) of the quadriceps measured on a dynamometer. This ratio reflects the proportion of maximal knee extensor capacity that was used during level walking. Pain was measured using the Knee Osteoarthritis Outcome Score (KOOS), a self-report questionnaire used for evaluating knee pain for people with OA. A higher KOOS score indicates less pain, whereas a lower KOOS score indicates more severe pain.
A series of multiple linear regressions were used to determine the relationship between pain and muscle capacity utilization, after adjusting for age, sex, body mass index (BMI), and gait speed as covariates. Results showed that there was no relationship between pain and muscle capacity utilization (p>0.05). However, female participants demonstrated lower MVIC (p<0.001) compared to males. Accordingly, a trend was observed such that females required a greater muscle capacity utilization to complete gait compared to males.
In conclusion, muscle capacity utilization was not associated with pain during walking in people with knee OA. Although the results of this study are insignificant, future work should further explore sex differences using a greater sample size and activities of daily living (ADLs).

▼ The overall goal of this thesis was to broaden knowledge of pain
mechanisms in myofascial temporomandibular disorders (M-TMD).
The specific aims were to:
• Develop a quality assessment tool for experimental bruxism
studies (study I).
• Investigate proprioceptive allodynia after experimental tooth
clenching exercises (study II).
• Evaluate the release of serotonin (5-HT), glutamate, pyruvate,
and lactate in healthy subjects (study III) and in patients with
M-TMD (study IV), after experimental tooth clenching
exercises.
In (I), tool development comprised 5 steps: (i) preliminary decisions,
(ii) item generation, (iii) face-validity assessment, (iv) reliability and
discriminative validity testing, and (v) instrument refinement. After
preliminary decisions and a literature review, a list of 52 items to be
considered for inclusion in the tool was generated. Eleven experts
were invited to participate on the Delphi panel, of which 10 agreed.
After four Delphi rounds, 8 items remained and were included in
the Quality Assessment Tool for Experimental Bruxism Studies
(Qu-ATEBS). Inter-observer reliability was acceptable (k = 0.77),
and discriminative validity high (phi coefficient 0.79; P < 0.01).
During refinement, 1 item was removed; the final tool comprised 7
items.
In (II), 16 healthy females participated in three 60-min sessions,
each with 24- and 48-h follow-ups. Participants were randomly
assigned to a repetitive experimental tooth clenching task with
10
a clenching level of 10%, 20%, or 40% of maximal voluntary
clenching force (MVCF). Pain intensity, fatigue, perceived intensity of
vibration (PIV), perceived discomfort (PD), and pressure pain
threshold (PPT) were measured throughout. A significant increase
in pain intensity and fatigue but not in PD was observed over time.
A significant increase in PIV was only observed at 40 min, and PPT
decreased significantly over time at 50 and 60 min compared to
baseline.
In (III), 30 healthy subjects (16 females, and 14 males)
participated in two sessions at a minimum interval of 1 wk.
Microdialysis was done to collect 5-HT, glutamate, pyruvate, and
lactate and to measure masseter muscle blood flow. Two hours after
the start of microdialysis, participants were randomized to a 20-
min repetitive experimental tooth clenching task (50% of MVCF)
or a control session (no clenching). Pain intensity was measured
throughout the experiment. Substance levels and blood flow were
unaltered at all time points between sessions, and between genders
in each session. Pain intensity was significantly higher after clenching
in the clenching session compared to the same time point in the
control session.
In (IV), 15 patients with M-TMD and 15 healthy controls
participated in one session and the methodology described above was
used. M-TMD patients had significantly higher levels of 5-HT and
significantly lower blood flows than healthy controls. No significant
differences for any substance at any time point were observed
between groups. Time and group…

▼ Osteochondrozė yra dažna liga, dėl
sumažėjusio fizinio aktyvumo ir ilgai sėdimo darbo tampanti XXI
amžiaus epidemija. Vis svarbesnės tampa nemedikamentinės gydymo ir
juosmens skausmo mažinimo priemonės, kuriomis atpalaiduojami ir
stiprinami liemens raumenys bei mažinamas dėl šios ligos
atsirandantis skausmas. Sergantiesiems stuburo juosmens srities
osteochondroze, greta kitų gydymo metodų dažnai taikomos
kineziterapijos procedūros. Darbo tikslas — nustatyti skausmo
pojūčio ir juosmens raumenų pajėgumo kaitą po taikytos
kineziterapijos sergantiems juosmeninės stuburo srities
osteochondroze. Tyrimo objektas — skausmo pojūtis ir atskirų
juosmens raumenų grupių pajėgumas.. Tyrimo uždaviniai: 1. Nustatyti
skausmo pojūtį prieš ir po kineziterapijos programos sergantiesiems
juosmeninės stuburo dalies osteochondroze. 2. Ištirti atskirų
juosmens raumenų grupių pajėgumą prieš ir po kineziterapijos
sergant stuburo juosmeninės dalies osteochondroze. 3. Palyginti
skausmo pojūčių ir juosmens raumenų pajėgumo pokytį dėl taikytos
kineziterapijos programos. Metodai. Tyrime dalyvavo 20 stuburo
juosmens srities osteochondroze sergančių ligonių (8 vyrai ir 12
moterų, amžiaus vidurkis – 50 metų). Pacientams juosmeninės stuburo
srities osteochondrozė diagnozuota bent prieš metus. Keturiems
pacientams kineziterapija taikyta pirmą kartą. Kineziterapija buvo
taikoma tris savaites, 5 kartus per savaitę po 30 – 45 minučių.
Kineziterapijos taikymo metu buvo atliekamas penkiolikos
palaipsniui programos... [toliau žr. visą

Osteochondrosis is a widespread disease of
the current century, and its increased and gradually becoming
epidemic manifestation is closely related to the widely spread
sedentary lifestyle. Prevention of and dealing with the disease
affecting lower back, as well as reduction in lumbago which is very
common feature of the manifestation of the lower back
osteochondrosis, are all gradually gaining grounds in the area of
the non-medication treatment approach, one of the indispensible
tools of which being kinesiotherapy, by which trunk muscles are
stimulated both to increase in strength and to relax when needed.
The aim of this study was to evaluate the changes in lower back
pain and the functionality of the trunk muscles due to the
kinesiotherapy program in patients with lower back osteochondrosis.
Object of the study — pain sensation and functionality of the
separate groups of trunks muscles. Objectives: 1. To follow the
changes in pain sensation during the physiotherapy treatment of
patients with lower back osteochondrosis. 2. To measure the changes
of (strength-endurance related) functionality of the separate
groups of trunks muscles after the physiotherapy program in
patients with lower back osteochondrosis. 3. To evaluate the
relative proportion of the changes in pain sensation and
functionality of the trunk muscles after the kinesiotherapic
program. Methods. The study involved 20 subjects with lower back
osteochondrosis, suffering the disease (which was diagnosed by a...

▼ Le syndrome du muscle piriforme (SMP) est une entité clinique probablement méconnue et sous-estimée en pratique courante. L'objectif de ce travail est d'apporter des arguments permettant d'aider à concrétiser la réalité de la responsabilité du muscle piriforme dans la souffrance provoquée sur le nerf ischiatique lors de son passage dans le foramen infra-piriforme.A partir de ("évaluation des rapports anatomiques locaux certaines manœuvres susceptibles de provoquer les contraintes du muscle piriforme sur le nerf ischiatique semblent plus sensibles et spécifiques. C'est ce qui est mis en évidence dans ce travail pour les manœuvres de Freiberg, PAIR et de Beatty. Il valide également la manœuvre « TG-CL » que nous mettons en avant.Pour optimiser le diagnostic de SMP, nous avons élaboré un score clinique à partir de 12 items. Ce score a été évalué sur une série personnelle de 250 patients comparés à 30 témoins avec conflit disco-radiculaire et 30 témoins sains. La sensibilité et la spécificité du score étaient respectivement de 96,4% et 100%, alors que la valeur prédictive était de 100% et la valeur prédictive négative de 86,9%. Pour les patients avec SMP nous avons proposé une prise en charge thérapeutique standardisée centrée sur le muscle piriforme. Le protocole médicamenteux et rééducatif permet d'obtenir 51,2% de guérison. Cent vingt deux patients en échec ont bénéficié d'injections de toxine botulinique. Les résultats évalués par l'EVA étaient très bons et bons dans 94 cas (77%), moyens dans 8 cas (7,4%) et mauvais dans 19 cas (15,6%). Quinze des 19 patients en échec ont été pris en charge chirurgicalement avec de très bons et bons résultats dans 12 cas
The piriformis muscle syndrome ( PMS ) has remained an ill-defined entity. It is a form of entrapment neuropathy involving compression of the sciatic nerve in the infrapiriformis canal. Our objective is, on the basis of anatomical descriptions of the piriformis muscle, to provide support for pathophysiological hypotheses. The manoeuvres that we have been reviewed are aimed at putting the piriformis muscle under stress in a variety of situation. We favour the PAIR and Freiberg stretching manoeuvres and Beatty's resisted contraction manoeuvre. When hip flexion surpasses 90°, the piriformis muscle is stretched in lateral rotation, and we have consequently laid emphasis on the manoeuvre we have termed Heel Contra-Lateral Knee (HCLK).To optimize the diagnosis of SMP , we developed a clinical score from 12 items. This score was evaluated on a personal series of 250 patients compared to 30 controls with disco-radicular conflict and 30 healthy controls. Sensitivity and specificity of the score were 96.4 % and 100 %, respectively, while the positive predictive value was 100 % and the negative predictive value of 86.9 %.Therapeutic management consists primarily of rehabilitation, making the patient aware of the benefits of daily self rehabilitation exercises. Combined medication and rehabilitation treatments had a cure rate of 51,2%.Hundred and twenty-two patients (48,8%)…
