▼ Older adults experience age-related challenges including muscle weakness, impaired mobility, and increased fall risk. Further, controlling submaximal muscle forces may also be impaired, particularly with eccentric (ECC) contracions, as they demonstrate greater vaiability in maintaining steady and accurate force output, characterized as muscle force steadiness (MFS), and functional mobility in older who have fallen is very limited. The primary and secondary aims of this dissertation were to compare whether repeated bouts of concentric (CON) and ECC contractions of the knee extensors improves MFS in healthy young (HYA), old (HOA) and older adults who have fallen (OIA), and whether MFS differes between the groups. The tertiary aim was to examine relationships between MFS, MFA and four functional mobility tests (FMT). An exploratory aim was to compare whether resistance training (RT), either traditional or negative eccentric work, improves MFS in OIA in a falls reduction program. Three groups, HYA (age 18-30), HOA (≥65), two or more co-morbid conditions), were recruited. Maximal voluntary isometric contractions (MVIC) were performed. A submaximal target force (50% MVIC) was used when measuring MFS and MFA. The OIA group then performed four FMT, and participated in 12 weeks of RT. Each group demonstrated early improvements in MFS with repeated bouts and obtained stable measures within six to nine trials. The OIA group exhibited greater force variabiliy for both CON and ECC contractions compared to HOA and HYA. HOA exhibited greater force variability for only CON contractions compared to HYA. No significant associations were seen between MFS and FMT. However, MFA and FMT were significantly correlated with moderate to strong associations for only ECC contractions. Twelve weeks of RT was effective in improving MFS for both CON and ECC contractions, while improvement in MFA was attained only during ECC contractions. MFS improved for different age groups under certain conditions with practice, yet differe between age groups. As MFA was associated with EMT during ECC contractions, it may be linked to impaired mobility in OIA. Improvements in MFS and MFA are attainable with RT.

▼ Knowledge of hand grip force is important in fields such as biomechanics, bioengineering, and ergonomics to measure the loads placed on the musculoskeletal system for assessing and reducing risk of injury and developing hands-free control systems for assistive devices. Difficulties in measuring and predicting grip force in occupational and daily situations have led researchers to explore indirect techniques for these purposes. Muscle electromyography (EMG) and more recently muscle-tendon dimensional changes have been investigated as indirect and non-invasive methods to evaluate hand grip force. This thesis proposes forearm surface dimensional changes (FDSC) as an alternative and novel indirect and non-invasive technique to measure hand grip force. However, practical applications of EMG signal or FSDC rely on the reliability of the measures and the ability to discriminate small changes in hand grip force. The aim of this study was to evaluate the potential of forearm surface EMG of hand and finger flexor muscles and anterior forearm surface dimensional changes for indirect measurement of hand grip force. The study established their predictive relationships and reliability and determined which muscle’s EMG signals and which surface locations on the forearm are best at differentiating varying grip forces and what level of grip force can be discriminated by EMG signals or FSDC. Furthermore, the study established intra-session and inter-day relative and absolute reliability of the measures for both EMG signals and FSDC in varying grip forces. The results of the study showed both linear and non-linear relationships between normalized root mean square (RMS) of EMG signals of different flexors and grip force and also between FSDC and grip force for different sites on the forearm. However, non-linear relationships could be approximated as linear for small to moderate forces (grip force < 50%). The study also showed that EMG can distinguish varying grip forces between 0% and 80% MVC. FSDC, on the other hand, were able to discriminate forces less than 50% MVC. Relative reliability of EMG of flexor muscles and FSDC showed moderate and high intra-session intraclass correlation coefficients (ICCs) for single and averaged measures respectively. Inter-day ICCs were considerably lower than intra-session ICCs showing poor and moderate relative reliability for single and averaged measures respectively. The results didn’t show any specific trend between the relative reliability and grip force or muscle or site on the forearm surface and were similar for both forearm EMG and surface shape changes. Absolute reliability of the measures, represented by standard error of measurement (SEm), increased with increasing grip force for EMG signals, indicating the dependency of EMG reliability on grip force. Conversely, SEm for FSDC was constant with no specific trend identified between SEm and increasing grip force. Normalized SEm, however, decreased with increasing grip force for both EMG and surface changes of the forearm as the magnitude… Advisors/Committee Members: Carman, Allan (advisor).

▼ Extraocular muscles are a unique group of skeletal muscles, with distinct biological properties, including specialized myofiber types, a unique transverse and longitudinal organization of myofibers, continued muscle plasticity and the retention of activated progenitor cells in adult normal muscles. Those biological features of contractile physiology enable them to meet the specialized functional demands of extraocular muscles: rapid eye movements (the fastest movement in the human body) and precise eye positioning. When contractile properties of extraocular muscles are imbalanced, this causes strabismus, which is an urgent situation in infancy because it disrupts the development of normal neurovisual circuits and binocular vision. In this dissertation, I examined the effects of three growth factors, IGF1 (Insulin-like Growth Factor 1), CT1 (Cardiotrophin 1), and GDNF (Glial-cell line derived neurotrophic factor), on contractile properties of extraocular muscles, and I provide evidence that these growth factors regulate development and plasticity of extraocular muscles. In the first project, I tested the hypothesis that IGF1 and CT1 strengthen superior oblique muscles of juvenile chickens. Using orbital injection of exogenous IGF1 and CT1, I measured the contractile force (twitch tension and tetanic tension) and muscle mass with an in-situ protocol. Both IGF1 and CT1 treatment increased the contractile force of superior oblique muscles to a similar degree, and CT1 also increased muscle mass. My morphological results supported the physiological findings. Both growth factors increased the myofiber area in transverse sections of proximal muscle segments. Furthermore, the number of proliferating cells labeled by BrdU also increased significantly in proximal and middle segments. Based on these data, I concluded that IGF1 and CT1 strengthen superior oblique muscles through increased cross-sectional myofiber area caused by the proliferation of progenitor cells. My second project tested the hypothesis that the growth factors IGF1, CT1, and GDNF contribute to the fast contractile kinetics of extraocular muscles that complete one single twitch contraction in much shorter time than limb skeletal muscles do. Using an in situ protocol, I recorded the contractile kinetics (contraction time and half relaxation time) of superior oblique muscle treated with exogenous growth factors or function-blocking proteins. I found that exogenous CT1 and GDNF shortened contraction time, while exogenous IGF1 and CT1 shortened half relaxation time. Blocking the function of endogenous IGFs prolonged both contraction time and half relaxation time, while neutralizing antibodies against GDNF prolonged contraction time. By quantifying and comparing levels of gene expression of growth factors regulating the fast kinetics of extraocular muscles, I found that the mRNA expression of three growth factors and their receptors were higher in extraocular muscles than those in limb skeletal muscles, implying that contractile kinetics are regulated by the… Advisors/Committee Members: von Bartheld, Christopher S (advisor), Kenyon, James (committee member), Burkin, Dean (committee member), Perrino, Brian (committee member), Baker, Josh (committee member).

▼ In 2000 and 2001 an estimated 150,000 children between the ages of 0 and 8 years old were injured or killed in a motor vehicle accident. Despite advances in child safety restraints and vehicle restraints, automobile accidents remain the primary cause of death for children in the 0-8 year old age group. In 1982, in an attempt to reduce the number of deaths and injuries of children, the first child crash test dummy was developed. The responses of this dummy were scaled from the adult response data based on the assumption that children were similar to adults both anatomically and physiologically, only children were smaller. It was also assumed that the soft tissue response, such as muscle force, was the same as for an adult. Recent studies have shown that not only are children different from adults due to the development of their skeleton, but that their ability to develop muscle force for a given cross-sectional area of muscle is also different. This difference calls into question not only the relationship that was used to develop the child crash test dummies but also the ability of these crash dummies to predict child injuries due to automobile impact. METHODS The aim of this study was to determine if the assumption of equivalent stress is appropriate. The muscle response of the neck muscles in 50th percentile adult male was compared to the neck muscle response of the 10-year-old boy under static and dynamic loading conditions. Magnetic resonance imaging was used to measure the muscle length, moment arm and cross-sectional area of the superficial flexor and extensor muscles of the neck. Two EMG studies were used to analyze the muscle force generated in the neck in response to static and dynamic loads. In the static study, subjects were asked to generate a maximal voluntary contraction (MVC) in four bending directions - flexion, extension and lateral left and right bending. Using and EMG-assisted optimization model, the forces and stresses in the superficial flexor/extensor muscles was calculated. The second EMG study was conducted during a low speed frontal impact in two test conditions - aware and unaware of the up-coming impact. The dynamic moment and displacement of the head were calculated. Latency of muscle activation in response to the onset of swing acceleration and peak swing acceleration were also examined. RESULTS Results of the MRI study confirmed the relationship between age and muscle moment arm (r=0.855, p=0.05 for the SCM), and age and muscle cross-sectional area (r=0.741, p=0.05 for the SCM) used in the Wolanin et al. scaling relationship. Both EMG studies showed that adults were able to generate higher applied moments (p<0.05) and muscle forces and moments (p<0.05) than 10-year old children in the same testing conditions. There was no difference in the stress generated during static loading of the neck… Advisors/Committee Members: John M. Cavanaugh.

▼ Human skeletal muscle is a highly metabolic tissue necessary for mobility and coordination. Responsible for approximately one-fifth of the resting human metabolism, skeletal muscle is also an important regulator of metabolites like glucose and contributes to the regulation of body temperature. Although there is a gradual decline in muscle mass associated with aging, a certain percentage of the population suffer from severe muscle mass and strength deterioration, classified as sarcopenia (5-13% for people aged 60-70 years old, 11-50% for those 80 or older). Sarcopenia is linked to increased morbidity and mortality rates in the elderly population, while annual healthcare costs related to sarcopenia total in the millions of dollars. Because the prevalence of sarcopenia is expected to increase as a larger percentage of the population transitions into old age, it becomes imperative to understand the mechanisms of aging and longevity so that more effective interventions can be taken against age-related muscle deterioration. Our laboratory has previously demonstrated that resveratrol, a known activator of the protein sirtuin 1 (SIRT1), was effective in enhancing human muscle adaptations to exercise in elderly populations. A rich body of literature has long supported the association of SIRT1 with longevity, but there are still gaps in our knowledge of how SIRT1 expression affects the functionality and performance of muscles in aging skeletal muscle. Furthermore, SIRT1 has been shown to be important in the function of muscle satellite cells—which are muscle stem cells that are responsible for the majority of muscle regeneration. However, there is little knowledge about how SIRT1 expression affects muscle regeneration and performance after injuries. To investigate the role of SIRT1 in the performance of aging and injured skeletal muscle, we have employed the use of several transgenic mouse models with differential expression of SIRT1. Using these models, we performed a series of functional muscle tests, before and after cardiotoxin (CTX) induced muscle injuries, to identify and compare muscle aptitude and recovery capability. Skeletal muscle sections from each model were also taken to identify differences in muscle fiber size and type distribution. Additionally, both mitochondria and satellite cells were isolated from these models to assess whether SIRT1 expression contributed to differences in metabolic or regenerative capacities. We found that there was little functional difference between young wild-type (YWT, aged 20-30 weeks) and aged (80+ weeks old) wild-type (WT-80), SIRT1 overexpressor (OE-80), and SIRT1 muscle-knockout (MKO-80) mice in either force production or fatigability in the absence of intervention. Mice lacking SIRT1 expression in their satellite cells (SKO-80), however, did show a reduction in force production. Interestingly, both the OE-80 and MKO-80 mice showed significant (P < 0.05) increases for p53 expression and reduced fatigability after recovering from injury, with the SIRT1 overexpressor model… Advisors/Committee Members: Stephen Alway, John Hollander, John Hollander.

▼ Background: Registering a true maximum bite force on the most commonly-used force transducers is problematic. It is often believed that this is related mainly to discomfort and the fear of breaking teeth. Objectives: The aim of the project was to compare the suitability of different bite force measuring transducers including ones which were designed to improve subject comfort. The transducers used were a traditional strain-gauge transducer with and without covering with ethylene vinyl acetate (EVA) sheets, and a newly-developed pressure transducer. Methods: Five separate studies were performed in this project. The experiments were carried out on human volunteer subjects (aged 24 to 41 years). They were all dentate with no missing anterior teeth and with no crowns on these teeth. The following procedures were used in some or all of the studies: measurement of MVBF, electrical stimulation of the masseter muscle, and EMG recording from two pairs of jaw closing muscles. Results: The highest MVBF values were recorded on the pressure transducer, mean (± S.D.) 464 N ± 224 N; followed by the strain-gauge transducer with EVA sheets, 243 ± 80 N; and last of all the strain-gauge transducer with silicone indices, 165 ± 35 N; or acrylic indices, 163 ± 82 N. Significantly higher maximum potential bite forces were predicted by twitch interpolation for the pressure transducer (730 ± 199 N) than for the strain-gauge transducer with EVA sheets, 354 ± 67 N (Paired t test, P < 0.05). Significantly higher EMGs of the masseter and anterior temporalis muscles were found to be associated with MVBFs on the pressure transducer than with MVBFs on the strain-gauge transducer with EVA sheets (Paired t test, P < 0.05). Conclusions: It is concluded that: a) the pressure transducer system and to a lesser extent the strain-gauge transducer covered with EVA sheets seemed to overcome the fear associated with biting on the hard surfaces of the strain-gauge transducer alone; b) the pressure transducer may have some multi-directional capabilities which allow for total bite forces, or at least larger parts of them, to be recorded than on a uni-directional strain-gauge transducer.

▼ Increased cyclic compressive loading in the medial compartment of the knee is associated with the progression of knee osteoarthritis (OA). However as medial knee OA is accompanied by a range of neuromuscular, morphological and structural changes throughout the lower limb, a clear consensus of the etiology of the disease is yet to emerge. Of particular recent interest are the roles of non-knee-spanning muscles and the lower-limb kinematic chain in the pathomechanics of knee OA. Joint loads during gait occur due to contributions from all muscles, gravity and inertia. As such the aim of this work was to utilise experimental gait data in conjunction with musculoskeletal modelling to undertake a novel and detailed examination of these individual constituent factors influencing loading in the osteoarthritic knee. Specifically, the objective was to decompose the time-histories of loads in the medial and lateral tibiofemoral compartments of osteoarthritic knees into contributions by individual muscles, gravity and inertia, and to explain the results in light of the known neuro-musculoskeletal changes associated with OA. A novel computational method for decomposing the tibiofemoral compartment loads into contributions by muscles, gravity and inertia was developed and integrated into an advanced musculoskeletal modelling pipeline. Experimental gait data from varus mal-aligned unilateral medial knee OA patients and healthy controls were input into the musculoskeletal modelling pipeline and used to quantify the contributions to the forces and cumulative loads in the medial and lateral compartments of the tibiofemoral-joint, and also to surrogate measures of medial compartment loading. The findings have revealed substantive differences in the composition of joint loads between healthy and osteoarthritic knees, and have explained some of the underlying mechanisms by which elevated knee-joint loads arise in OA patients. Importantly, the findings establish the substantial role played by non-knee-spanning muscles in modulating knee-joint loads. Furthermore, this thesis has also quantified and explained some of the potential limitations associated with surrogate measure of joint loads. The improved understanding of the pathomechanics of medial knee OA brought about by this thesis may be potentially valuable in the design of non-pharmacologic interventions to mitigate medial knee OA progression, and may facilitate the development of more robust surrogate measures of knee-joint loads to improve clinical assessment of OA patients.

▼ Previous studies on change of direction (COD) have reported that braking is an important factor for COD performance. However, previous studies have focused on the plant step and the penultimate step (PEN), thus little is known about deceleration before these steps. This study compared ground reaction forces (GRF) of two braking steps, the PEN and the step prior to PEN (PEN-1), the entry and exit velocity of the COD, and muscle function measures (leg press and leg curl one-repetition maximum, isometric and isokinetic strength, and drop jump performance) between faster and slower participants for a 90o sidestep cut. This study also examined the associations between the time taken from 1 m before and 1 m after COD (1-1 m COD time), braking GRF during deceleration and muscle function. Twenty-two male recreational athletes from AFL (n = 2), soccer (n = 8), rugby (n = 2), basketball (n = 5), squash (n = 1) and tennis (n = 4), performed a total of six cuts with their dominant (DL) and non-dominant legs (NDL). The faster group (n =10; DL: 0.19 ± 0.02 s, NDL: 0.22 ± 0.02 s) and the slower group (n = 10; DL: 0.24 ± 0.02 s, NDL: 0.31 ± 0.04 s) as well as pooled (n = 20) DL and NDL (DL: 0.21 ± 0.03 s, NDL: 0.26 ± 0.04 s) were used for analyses. Dependent variables between the groups were compared using independent t-tests with sequential Bonferroni corrections to control for type I error. Pearson’s correlation was used to examine the relationship between the 1-1 m COD time and dependent variables. Faster DL COD participants showed significantly greater change in braking impulse from PEN-1 to PEN (-0.50 ± 0.31 vs -0.20 ± 0.15 m⋅s-1, p = 0.027) whereas faster NDL COD participants showed greater isometric knee flexor torque (1.94 ± 0.25 vs 1.63 ± 0.26 Nm⋅kg-1, p = 0.005), isometric extensor torque (3.37 ± 0.42 vs 3.17 ± 0.71 Nm⋅kg-1, p = 0.017) and concentric isokinetic (90o⋅s-1) knee extensor torque (3.02 ± 0.47 vs 2.47 ± 0.39 Nm⋅kg-1, p = 0.03). Pooled DL and NDL comparison revealed significantly higher plant step braking impulse (0.61 ± 0.23 vs 0.47 ± 0.23 m⋅s-1, p = 0.043) and lower propulsive impulse (2.42 ± 0.47 vs 2.77 ± 0.47 m⋅s-1, p = 0.008) during DL COD. Faster NDL COD was associated with greater NDL eccentric knee flexor at 90o⋅s-1 (r = 0.648, p = 0.003), 60 cm drop jump (r = 0.556, p = 0.010), greater NDL isometric knee flexor torque (r = 0.473, p = 0.024) and greater NDL eccentric knee extensor at 90os-1 (r = 0.470, p = 0.041). These results indicate that mechanical factors influencing DL and NDL COD performance were different. In addition, deceleration steps ranged between three to five steps with braking between PEN-1 and PEN resulting in faster DL COD performance. Further studies are is required to examine the deceleration starting at PEN-1 and should consider multifactorial analyses to capture multiple strategies potentially implemented.

▼ Rotator cuff (RTC) tears impair upper limb mobility and affect 20% of the adult population. Unfortunately, surgical repair of major RTC tears often fails to restore shoulder function and has a high risk of re-tear. RTC tears induce irreversible, degenerative changes to the muscle that may hinder the recovery of shoulder function. Currently, very few studies have comprehensively assessed RTC muscle function, thus, little is known about which markers may be able predict changes in function after RTC tear. In this dissertation, I present three studies designed to systemically determine the impact of a RTC tear on contractile function of the supraspinatus (SS), the muscle most commonly affected in the RTC. In study1 I developed a novel method to test in vivo SS contractile function using animal species common to RTC research. In study #2, I found that the SS exhibited a 30% loss in force prior to onset of muscle atrophy after acute RTC tear using the rat model. The initial loss of force was associated with a decrease in the size and continuity of the neuromuscular junction (NMJ). The SS muscle was also more susceptible to injury, which was associated with a reduction in collagen packing density. Therefore, SS size is not the strongest predictor of force output with acute RTC tears. In addition, the increased susceptibility to injury could compound the dysfunction already apparent in the SS muscle after RTC tear. In study #3, I found that the rabbit model experienced a 40% loss of force after 6 weeks of RTC tear that persisted at 12 weeks. Using a number of different in vivo and ex vivo imaging approaches I found the degree of fatty infiltration (FI) to be the strongest predictor of muscle force production after RTC tear. Surprisingly, the data suggested that muscle atrophy only explained the loss in force in torn muscles when little to no FI was present. Therefore, FI is a prognostic marker for muscle weakness after RTC tear, and can help clinicians predict the force generating capacity of the SS for surgery and rehabilitation decision-making. Results from both studies found that SS contractile function was significantly impaired after RTC tear, and identified measureable markers beyond muscle atrophy that were associated with the loss in muscle force that may act as potential therapeutic targets to improve functional outcomes after RTC tear.

▼ Esta tese está dividida em três estudos. No estudo I desta tese, os objetivos foram descrever a cinemática tridimensional do ombro e determinar a contribuição da articulação escápulotorácica no movimento total de elevação. No estudo II, os objetivos foram descrever a atividade eletromiográfica (EMG) e o percentual de cocontração entre os músculos deltóide médio e redondo maior. No estudo III, o objetivo foi determinar o valor máximo da força de contato gleno-umeral e da força muscular. Quarenta sujeitos participaram dos estudos divididos em três grupos: pacientes com prótese total do ombro (PTO), com prótese reversa (PRO) e um grupo controle. Todos realizaram dois exercícios de reabilitação (flexão e elevação no plano escapular) usando diferentes cargas (sem carga externa, halter de 1kg e resistência elástica). A cinemática do ombro foi registrada por meio de um dispositivo eletromagnético de rastreamento, a atividade EMG foi registrada por meio de um eletromiógrafo de 16 canais e o modelo matemático utilizado foi o Delft Shoulder and Elbow Model. As análises estatísticas foram feitas por meio de ANOVAs de dois e três fatores para medidas repetidas. Foi utilizado o teste post hoc de Bonferroni e o nível de significância adotado foi de α < 0,05. Os resultados do estudo I mostram que a escápula contribui mais para o movimento total do ombro em pacientes com prótese em relação aos indivíduos saudáveis e em exercícios realizados com 1 kg e resistência elástica comparados com os exercícios sem carga externa. O ângulo de elevação glenoumeral durante a flexão foi significativamente maior no grupo PTO em comparação ao grupo PRO. O estudo II identificou maior atividade EMG do deltóide médio e posterior no grupo PTO em comparação ao grupo controle e um aumento da atividade EMG do peitoral (parte esternal) no grupo PRO em comparação ao grupo PTO e ao grupo controle. Para os outros músculos (deltóide anterior, redondo maior, peitoral maior - parte clavicular e serrátil anterior) não foram encontradas diferenças significativas entre os grupos. Para todos os músculos, exceto o serrátil anterior, a atividade EMG foi menor nos exercícios sem carga externa quando comparados aos exercícios com 1 kg e resistência elástica. Nenhum efeito principal dos fatores grupo e carga foi encontrado no percentual de cocontração. No estudo III, o grupo controle apresentou maior força de contato gleno-umeral máxima quando comparado ao grupo PTO durante a flexão, mas não foram encontradas diferenças entre os grupos de pacientes nos dois movimentos. A resistência elástica apresentou maiores valores de força de contato gleno-umeral em todos os grupos. O valor máximo da força de todos os músculos analisados variou de 0,32 N a 772 N e o manguito rotador e o deltóide foram os músculos que apresentaram os maiores valores de força em todos os grupos. A presente tese sugere que para uma mesma amplitude de movimento, os pacientes com prótese de ombro apresentarão um movimento escapular maior compensando a perda do movimento gleno-umeral.

▼ Knowledge of shoulder muscle and joint forces during daily living activities is important for developing injury prevention strategies, tailoring exercise therapies and rehabilitation, and design of joint replacements. As non-invasive measurement of muscle force is currently not possible, computational strategies have been widely employed to solve this challenge. The muscle force equilibrium problem at the shoulder complex is statically indeterminate, due to the higher number of joint actuators than degrees of freedom of joint movement. This precludes a unique solution of muscle forces. Optimisation methods, which are most commonly used to solve this indeterminacy problem, have been used to decompose calculations of net joint moments into muscle forces; however, it is thought that these approaches underestimate muscle co-contraction. The objective of this thesis was to develop the first fully electromyography (EMG)-driven neuromusculoskeletal modelling framework to evaluate shoulder muscle and joint function. The specific aims were to use this framework to (i) evaluate neuromusculoskeletal function of the shoulder during upper limb activities of daily living, including muscle and joint forces (ii) validate model function by comparing muscle-generated joint moments with inverse dynamics joint moments and comparing glenohumeral joint force calculations with in vivo measurements using instrumented implant data (iii) investigate the effect of EMG-driven neuromusculoskeletal model calibration strategies on muscle and joint force calculations, and (iv) compare muscle and joint force predictions from the EMG-driven neuromusculoskeletal model with calculations using static optimisation. Four healthy adults performed three groups of functional upper limb tasks representing activities of daily living: active abduction, flexion, reaching and head touching, mid-range submaximal isometric abduction, adduction, flexion, extension, internal rotation and external Abstract ii rotation, as well as passive functional abduction and flexion. EMG data from 16 shoulder muscles were simultaneously acquired using surface and intramuscular electrodes, and upper limb kinematic and external forces measured. Subject calibrated neuromusculoskeletal models were developed for each subject using OpenSim. Muscle forces, resultant joint torques, and contact forces were subsequently calculated using EMG data, joint kinematics, and external forces as inputs to the model. Anterior and middle deltoid were the major arm elevators and generated the greatest muscle force among all glenohumeral muscles. Infraspinatus and supraspinatus were active in all upper limb tasks investigated and were also important contributors to joint motion and stability. Glenohumeral joint forces showed high agreement with previously reported in vivo instrumented implant data, while muscle-generated joint moments showed close agreement with net joint moments calculated using inverse dynamics. Calibration of the EMG-driven neuromusculoskeletal models over a wide range of…

▼ Spinal cord injury (SCI) leads to significant deficits in muscle strength and mass, impacting negatively on physical health and quality of life (QoL). Physical rehabilitation techniques for people with SCI rely on constant updates and the accumulation of evidence regarding the efficacy of available and/or new physical interventions. Neuromuscular electrical stimulation (NMES) is already commonly used to activate skeletal muscles and subsequently reverse muscle atrophy, however NMES as a high-intensity “strength training” intervention appears to be a particularly promising technique for increasing muscle strength and mass and to subsequently improve physical health and quality of life (QoL) in people with SCI. Nonetheless, there are many factors limiting the use of standard NMES protocols, and further evidence pertaining to the use of high-intensity NMES strength training in clinical populations is warranted. The primary aim of the research described in this thesis was to examine the effects of NMES as a high-intensity muscle strength training intervention, specifically using wide-pulse width (1000 μs), low-to-moderate frequency (30 Hz) NMES combined with tendon vibration, on muscle strength and mass, physical health, symptoms of spasticity and QoL in people with SCI. This thesis includes two cross-sectional studies examining the effects of patellar tendon vibration (55 Hz, 7 mm amplitude) superimposed onto wide-pulse width (1000 μs) NMES (e.g. 30 Hz over 2 s) on the peak muscular (knee extensor) force and total impulse elicited by, and rate of recovery from, the intervention in healthy subjects (Study 1) and in people with chronic SCI (Study 2). The results of Study 1 revealed that superimposing tendon vibration onto wide-pulse width NMES leads to an increase in the muscle work performed before fatigue in only some individuals (i.e. positive responders, 50% of individuals in the current study), but decreases it in others (i.e. negative responders). However, it tends to reduce the voluntary force loss that was consistently experienced after a training session using high-intensity NMES, and may thus allow for additional exercise or rehabilitation work to be performed without ongoing voluntary muscle fatigue in healthy people. The results of Study 2 also identified positive and negative responders to tendon vibration in people with SCI, however the responses were less clear and a defined effect of tendon vibration superimposed onto NMES was not discerned. In Study 3, a 12-week (twice-weekly) high-intensity NMES strength training intervention was implemented in people with chronic SCI; based on results of Study 2, high-force contractions were evoked by NMES without superimposed tendon vibration. A significant increase in muscle mass (45%) and strength (tetanic evoked force; 31.8%), amelioration of spasticity symptoms, and improvement in some aspects of physical health and QoL were observed. Therefore, the use of high-intensity NMES strength training appears to be an effective rehabilitation tool to increase muscle force…

▼ BACKGROUND: Knee problems are the most common complaints of the lower extremity in the Netherlands. Osteoarthritis has the highest prevalence of all knee complaints. Knee osteoarthritis is likely to start at the patellofemoral joint and is associated with the aggravation of pain. Mechanical overloading is hypothesized to contribute to the development and progression of patellofemoral osteoarthritis (PFOA). Several studies have explored the mechanical loading pattern of the patellofemoral joint. Because different biomechanical models were used, vastly different estimations of the patellofemoral joint contact force (PFJCF) were concluded. This diversity prevents a clear understanding of the role of mechanical overloading in PFOA, since it is unknown how different biomechanical models affect the PFJCF estimation. OBJECTIVES: This study will explore how different biomechanical models of the patellofemoral joint affect the estimated PFJCF for common weight-bearing activities. METHODS: Ten healthy participants were included in this study. Common weight-bearing activities (walking, stair ascending, stair descending, sit-to-stand and stand-to-sit) were performed in the motion lab. Marker trajectory data and force plate data were collected. The data were input to biomechanical models used to estimate the quadriceps muscle force and subsequently the PFJCF. The quadriceps muscle force was estimated using the inverse dynamics and static optimization method. From there on, the PFJCF was estimated using three PFJCF to quadriceps muscle force ratios (P2QFRs), each based on a different patellofemoral joint model (i.e. van Eijden’s model, Yamaguchi’s model and Gill’s model). For each weight-bearing activity, the peak PFJCF was obtained and the magnitude of the difference among the biomechanical models was explored. RESULTS: The static optimization method resulted in a significantly higher peak PFJCF compared to the inverse dynamics method in walking (largest effect size was 0.10 BW). However, for stair descending, sit-to-stand and stand-to-sit, the inverse dynamics method resulted in a significantly higher peak PFJCF compared to the static optimization method (largest effect size was 0.45 BW, 1.17 BW, 1.25 BW, respectively). No significantly difference was found for stair ascending. For walking, Yamaguchi’s model resulted in a significantly higher peak PFJCF compared to van Eijden’s model and Gill’s model, and van Eijden’s model resulted in a significantly higher peak PFJCF compared to Gill’s model (largest effect size was 0.06 BW). For stair ascending, stair descending, sit-to-stand and stand-to-sit, Gill’s model resulted in a significantly higher peak PFJCF compared to van Eijden’s model and Yamaguchi’s model. For stair descending the van Eijden’s model resulted in a significantly higher peak PFJCF compared to Yamaguchi’s model. The largest effect size was 0.15 BW, 0.32 BW, 0.72 BW and 0.72 BW, for respectively stair ascending, stair descending, sit-to-stand and stand-to-sit. CONCLUSION: The choice of a biomechanical model has a… Advisors/Committee Members: Harlaar, Jaap (mentor), Macri, Erin (graduation committee), Seth, Ajay (graduation committee), Weinans, Harrie (graduation committee), Delft University of Technology (degree granting institution).

▼ With a prevalence of 17% in men and 4% in women, Femoroacetabular Impingement (FAI) of type cam is characterized by a decreased femoral head-neck offset and/or asphericity of the lateral femoral head, associated with groin pain and reduced hip range of motion. Since the aetiology is still unclear, the mechanisms of development, progression and degeneration of FAI are largely investigated. Musculoskeletal modeling can support the development of a biomechanical framework to advance the research on FAI pathomechanisms, expand the knowledge about hip contact load distribution in FAI population, and relate the muscle and hip contact forces to the alterations observed during functional tasks. Therefore, this thesis is composed of two parts: the development of a methodological framework, and its application to the investigation of FAI pathomechanisms. The variability of the modelling outcomes (i.e.., body kinematics, torques, contact and muscle forces) to different marker sets, pelvic marker misplacements, and hip joint center (HJC) location was investigated within an inverse kinematic framework. The findings from such studies supported the modelling choices for the clinical investigation of FAI pathomechanisms. In particular, the performance of three different marker sets (Plug-in-Gait, University of Ottawa Motion Analysis Model and a 3-marker-cluster marker set) was compared, and absolute and relative reliability indices were calculated with the purpose of finding a simple yet reliable marker set to be used within an inverse kinematic framework in a clinical study. Thereafter, the sensitivity of joint angles, moments and hip contact forces to simulated inaccurate pelvic tilt was analyzed. The resulting variability indices were high with variations up to 1.3 times the body weight in hip contact forces. The kinematic variations propagated non-linearly to all planes and joints, showing the importance of adjusting possible pelvic misalignments. A methodology was presented to correct the pelvic alignment when the relative position of surface pelvic markers with respect to bony landmarks is known from medical images. The HJC location is a crucial modelling parameter in the analysis of hip kinematics and forces. A certain degree of customization could be introduced in the model by using HJC measured from medical images. Therefore, the performance of a generic musculoskeletal model with customized or non-customized HJC was compared during walking. Hip contact forces were highly sensitive to HJC location, especially because of the dependency of muscle moment arms to HJC changes. However, the variation of HJC without consistent muscle anatomy customization introduced artifacts that could potentially produce inaccurate muscle and joint contact forces estimation. When HJC cannot be measured from medical images, regression equations can be used instead. Therefore, the validity of two popular HJC regression equations (Harrington and Davis) was tested on FAI participants using non-parametric statistical and Bland-Altman tests. The…

Sport i fizičko vaspitanje - opšta motorika čoveka / Sports and Physical Education - human general motor skills

Problem istraživanja je fundamentalnog karaktera i formulisan je na osnovu metodoloških nedostataka istraživanja u kojima je ispitivan uticaj komponenti opterećenja na kinetičke i kinematičke parametre određenih zadataka. Problem u istraživanju je ispitivanje uticaja inercione i gravitacione komponente opterećenja na balističke pokrete. Ovaj problem, do sada, istraživan je na pokretima koji se realizuju u horizontalnoj ravni, međutim, zbog neophodne kolinearnosti komponenti opterećenja, mogućnost upoređivanja gravitacione i inercione komponente opterećenja postoji samo u pokretima koji se odvijaju u vertikalnom pravcu. Zbog toga ne postoje metodološki validne informacije o efektima pojedinih komponenti opterećenja na kretanje čoveka. Uticaj komponenti opterećenja, u ovom istraživanju, ispitivan je na zadacima maksimalnih skokova uvis i izbačaja iz ležećeg položaja na klupi. Na taj način, ispitivan je uticaj inercione i gravitacione sile na dinamička svojstva mišića ruku i mišića nogu. Takođe, uticaj pomenutih komponenti opterećenja na zadatke koji se realizuju u vertikalnom pravcu ispitivan je na pokretima sa većim i manjim brojem stepeni slobode, tako što je efekat komponenti opterećenja na dinamička svojstva mišića nogu ispitivan u zadacima maksimalnog skoka uvis sa zamahom rukama (SV) i maksimalnog skoka uvis iz polučučnja bez zamaha rukama (SVpč). Za potrebe ovog istraživanja korišćena je potpuno nova tehnika (trenažer) kojom se istovremeno ili selektivno uticalo na intezitet inercione i gravitacione komponente spoljašnjeg opterećenja. Simulacija gravitacione komponente opterećenja proizvedena je primenom konstantnog elastičnog opterećenja (elastične gume), istovremeno delovanje inercione i gravitacione komponente opterećenja obezbeđeno je dodavanjem tegova, a izolovano delovanje inercione sile omogućeno je neutralisanjem gravitacione komponente spoljašnjeg opterećenja (tegova), primenom elastičnog rasterećenja...

▼ ABSTRACT Background: Myotonic dystrophy type 1 (DM1) is a neuromuscular multisystemic disorder with slowly progressive muscle weakness. The overall purpose of this thesis was, in adult patients with DM1, to investigate factors of importance for functional balance skills and falls, and to investigate the natural course of muscle force and functional balance impairments, with reliable measurement methods. Methods: In the first study we evaluated test-retest reliability in static and dynamic balance tests and gait, with three assessment occasions spaced oneweek apart, in ten patients with DM1. In the second study, which is a crosssectional study, 51 patients were assessed for muscle strength, gait and functional balance together with self-reported balance confidence, walking ability and falls. A multivariate analysis of factors of importance for functional balance impairment was performed. Of these 51 patients, 43 were further analysed in a third five-year prospective study for changes in muscle force, gait and functional balance together with self-reported balance confidence, walking ability and falls. Results: The test-retest reliability analysis results advocate dynamic balance tests and timed gait before the static tests. The cross-sectional study shows that falls are common in the weaker, but still ambulant, patients. A combination of weak ankle muscles and a physical capability to accelerate to fast walking increased the risk of falling. Over five years the distal muscles of the leg have a more steep force decrease than the proximal muscles. There was a tendency towards a greater worsening in males, and we found a statistically significant difference between genders in the knee extensor and flexor force change. All men had fallen within the previous year at the fiveyear assessment. Injuries of the face and head were more frequent at five years. Conclusions: Test-retest reliable dynamic balance tests and isometric muscle force measures showed that there is a statistically significant decrease in functional balance skill and in leg muscle force after five years in patients with DM1. The number of patients who had fallen had increased and the fall injuries were worse. It is of great importance to prevent falls especially in those who are at most risk for falls, by which we mean those who have a more steep muscle force reduction. Regular assessments of gait, functional balance and leg muscle force could be a way to determine who is at most risk for falls. This would give the opportunity to intervene with rehabilitation therapy and assistive devices as possible means for fall prevention in patients with DM1.

▼ Partial foot amputation is the most common amputation performed in the world today. In Australia, over 74% of all lower limb amputations are partial foot amputations. Diabetic patients are 15 times more likely to have an amputation than people without diabetes. Despite the prevalence of partial foot amputation, the influence of different levels of amputation on the biomechanics of gait is not well understood. This research project aimed to develop subject-specific musculoskeletal models to simulate and analyse gait in people with partial foot amputation, including quantification of the forces developed in the lower limb muscles during walking. One subject with transmetatarsal amputation and another with metatarsophalangeal amputation were selected based on inclusion criteria. In the transmetatarsal subject, the effects of compromised metatarsals on spatiotemporal data, kinematics, kinetics and individual muscle forces were compared with those of a control subject with metatarsophalangeal amputation through toes. The validation of developed models showed that predicted joint angles and joint moments were comparable to those reported in another study so developed musculoskeletal models for subjects were used for individual muscle force prediction of lower limb muscles during stance. For some muscles, the timing of forces predicted by the models and the timing of their EMG data were comparable so the forces predicted for muscles were reliable so far. The results showed that once the metatarsals are compromised through transmetatarsal amputation, some gait abnormalities were observed. These changes in gait were caused by an inability to generate power across the ankle joint. In the residual limb with transmetatarsal amputation, the reduction in the magnitude of the net ankle joint moment was associated with the reduction in the calf muscle forces during terminal stance and pre-swing of the gait. Compromised metatarsals through transmetatarsal amputation may impair the biomechanics of gait significantly through the reduction in the capacity of calf muscle forces to plantar flex the ankle and generate the necessary ankle torque to propel the residual limb.

▼ There are three main physiological governing mechanisms for cardiac contractility; the force-frequency response, the length-tension response, and the beta-adrenergic response. One of the major hallmarks of heart failure is a decrease in the force of contraction with increasing frequency. Here we utilize the ex vivo isolated cardiac muscle in an attempt to discuss the physiological role of the force-frequency response in health. We aim to determine the functional attributes of the normal heart by studying alterations in contractility, calcium transient amplitude, and phosphorylation status following changes in frequency, alterations in beta-adrenergic stimulation, and chronic stretch. All experiments were conducted on isolated muscle preparations extracted from the right ventricular free wall of the male New Zealand white rabbit. Our hope is to increase the understanding of the manipulations and alterations that occur in the context of the force-frequency response in health. We first determined the direct changes in the calcium and force response on a beat-to-beat basis during an instantaneous change in frequency. Because heart failure is rarely a spontaneous event, determining the minute changes in calcium transient amplitude as it relates to force production provides insight into the intricate balance that occurs at every beat. In this study we were able to highlight the dynamic relationship between force and calcium during the process of force stabilization at different frequencies. In additional studies, we determined the effects of beta-adrenergic stimulation in conjunction to the force-frequency response. This work aimed to combine the force-frequency response with the beta-adrenergic response in a controlled manner. These experiments highlighted a modulation of the force-frequency response during beta-adrenergic stimulation, suggesting an important role for beta-stimulation in immediate contractile alterations which have an inhibitory effect on the response to frequency. Finally, we determined the time dependent effects of stretch on alterations of the force-frequency response. We show that if a muscle is set to contract at a maintained stretch, there is a significant reversal of the force-frequency response that occurs in conjunction with alterations in the phosphorylation state of key myofilament proteins after 24 hours. Taken together, these results highlight potential modulators of the force-frequency relationship, which could be ideal targets for future work. Advisors/Committee Members: Janssen, Paul (Advisor).
