▼ It has been known for some time that eccentric exercise produces significant muscle damage resulting in changes in muscle structure and function, leading to a fall in maximal force production, a rise in passive tension, as well as delayed-onset muscle soreness. The majority of studies to date have focussed on examining the structural changes in the muscle, however, little is known about how the nervous system responds to eccentric exercise-induced muscle damage. This thesis has investigated for the first time changes at the level of single
motor unit activity following eccentric exercise, which provides specific information about the activity of spinal
motor neurons that can reveal details of the nature of the neural adaptations to repeated eccentric contractions. Muscle damage was induced in experiments in Chapters 2 and 3 by controlled lowering of a hand-held load, requiring eccentric contraction of the elbow flexor muscles, and in Chapter 4, by maximal voluntary eccentric contractions of the elbow flexors on an isokinetic dynamometer, to induce a 40% reduction in MVC force in all subjects. As well as an extended reduction in MVC force, I found consistent with results from previous studies a reduction in relaxed elbow joint angle (indicative of a rise in passive tension) up to 24-hrs after the exercise and delayed-onset muscle soreness a day later. An increase in sub-maximal biceps brachii EMG activity and increased force fluctuations for up to 24-hrs after the exercise was also found, along with increased antagonist activity from triceps brachii EMG immediately after eccentric exercise, confirming results from other studies. Following a single bout of eccentric exercise, I found an increase in correlated
motor unit activity (
motor unit synchronization and coherence; Chapter 2) and a reduction in the force at which
motor units were recruited (Chapter 3) that lasted for at least 24 hours after the exercise. Minimum
motor unit discharge rates were also influenced by eccentric exercise, but had recovered 24 hours later (Chapter 3). These findings indicate that eccentric exercise-induced muscle damage alters the correlated discharge behaviour and recruitment threshold of human
motor units in elbow flexor muscles for ≤ 24 hrs. It was therefore hypothesised in Chapter 4 that a lasting adaptation in correlated
motor unit activity and/or
motor unit recruitment may contribute to the “repeated bout effect”, which results in reduced muscle damage from a subsequent bout of eccentric exercise. In Chapter 4, a repeated bout of eccentric exercise performed 7 days after the initial bout resulted in reduced symptoms of muscle damage, including a faster recovery of muscle strength, and reduced development of muscle soreness.
Motor unit activity measured 7 days after the initial bout of exercise (immediately before the repeated bout) showed elevated
motor unit synchronization, but a recovery of
motor unit recruitment threshold to pre-exercise levels. These findings are the first to demonstrate a long-term neural adaptation following…

▼ Muscles consists of multiple
motor units (MUs) that produce the force required for our movements.
Motor unitproperties are responsible for the relation between neural excitation and muscle force (excitation-force relation). Theforce of the muscle is dictated by the recruitment and the force output of the different
motor units. The recruitmentis physiologically determined by the recruitment thresholds of the
motor units, where
motor units with a higher forceoutput are thought to have a higher recruitment threshold, conform Henneman’s orderly recruitment principle. Thegoal of this study was to predict the effects of the MU-threshold and MU-force output distributions on the excitation-force relation of a muscle. Assuming that a muscle’s excitation-force relation depends on the values of the
motor unitproperties present in the muscle, the recruitment threshold and maximum force distributions among the
motor unitscan be derived from muscle force recordings. To achieve the goal a computer model was build to simulate
motor unitrecruitment and force production of a group of MUs with different (combinations) of MU-threshold and maximum MU-force output distributions. Both MU-threshold distribution and maximum MU-force output distribution of the musclewere mathematically varied between linear and exponential curves. Input of the muscle model was a linear increasingneural activation profile and the force output profile of the muscle was simulated. The resultant MU-activation andforce patterns were compared with published results of simultaneous MU-recruitment and force recordings obtainedfrom literature. The simulation results showed that the excitation-force profile does not show characteristics thatcan be linked to either the MU-threshold distribution or the MU-force output. As a consequence, force recordingsalone are not sufficient to estimate the recruitment threshold and maximum force distributions. However, the use of acomputer model in combination with additional recorded data such as (surface) electromygraphy (EMG) is expectedto show results from which estimating MU properties is possible.

▼ Electromyographic (EMG) signal decomposition is the process of resolving an EMG signal into its component motor unit potential trains (MUPTs). The extracted MUPTs can aid in the diagnosis of neuromuscular disorders and the study of the neural control of movement, but only if they are valid trains. Before using decomposition results and the motor unit potential (MUP) shape and motor unit (MU) firing pattern information related to each active MU for either clinical or research purposes the fact that the extracted MUPTs are valid needs to be confirmed.
The existing MUPT validation methods are either time consuming or related to operator experience and skill. More importantly, they cannot be executed during automatic decomposition of EMG signals to assist with improving decomposition results. To overcome these issues, in this thesis the possibility of developing automatic MUPT validation algorithms has been explored. Several methods based on a combination of feature extraction techniques, cluster validation methods, supervised classification algorithms, and multiple classifier fusion techniques were developed. The developed methods, in general, use either the MU firing pattern or MUP-shape consistency of a MUPT, or both, to estimate its overall validity.
The performance of the developed systems was evaluated using a variety of MUPTs obtained from the decomposition of several simulated and real intramuscular EMG signals. Based on the results achieved, the methods that use only shape or only firing pattern information had higher generalization error than the systems that use both types of information. For the classifiers that use MU firing pattern information of a MUPT to determine its validity, the accuracy for invalid trains decreases as the number of missed-classification errors in trains increases. Likewise, for the methods that use MUP-shape information of a MUPT to determine its validity, the classification accuracy for invalid trains decreases as the within-train similarity of the invalid trains increase. Of the systems that use both shape and firing pattern information, those that separately estimate MU firing pattern validity and MUP-shape validity and then estimate the overall validity of a train by fusing these two indices using trainable fusion methods performed better than the single classifier scheme that estimates MUPT validity using a single classifier, especially for the real data used. Overall, the multi-classifier constructed using trainable logistic regression to aggregate base classifier outputs had the best performance with overall accuracy of 99.4% and 98.8% for simulated and real data, respectively.
The possibility of formulating an algorithm for automated editing MUPTs contaminated with a high number of false-classification errors (FCEs) during decomposition was also investigated. Ultimately, a robust method was developed for this purpose. Using a supervised classifier and MU firing pattern information provided by each MUPT, the developed algorithm first determines whether a given train is…

▼ There is limited information regarding the normal function of the medial pterygoid (MP) muscle, a major jaw muscle. The aims of our study were to develop a methodology to record from the MP during standardized isometric jaw closing tasks, to determine the range of tasks over which activity can be recorded in the MP, and to determine whether there is evidence for functional heterogeneity within the MP muscle by comparing electromyographic (EMG) features in different regions of the MP. Fifteen healthy participants were included in the study. The EMG activity of the right MP was recorded with intramuscular electrodes during the performance of isometric jaw closing tasks onto a force transducer as well as isometric contralateral (i.e. to the left side), protrusive (straightforward) and ipsilateral (i.e. to the right side) jaw tasks using another force transducer in the same participants. The isometric tasks were ramp tasks (at a fast rate and at a slow rate) and step level tasks (at 2 force levels). A computed tomography (CT) scan was performed for all participants and the presence of MP activity, thresholds of single motor units, and root means square (RMS) activity were assessed in the tasks. The MP was active in all jaw closing tasks in all participants, but in the horizontal tasks, the MP was mostly active in the protrusive and contralateral tasks (85% of participants), while it was activated in 57% of the participants in the ipsilateral tasks. The mean force threshold value for the fast jaw closing ramp task was significantly (P<0.05) lower than for the slow jaw closing ramp task. However the differences were not significant for any of the horizontal tasks. The EMG activity of the MP in all jaw closing and horizontal tasks was positive except for the ipsilateral tasks when the MP was not active in the ipsilateral tasks at all. CT scan verifications of the electrodes locations suggest a more important role for the lateral part of the MP in the generation and/or control of the horizontal jaw force tasks than the medial part. Also, a crucial role for the medial part in the vertical jaw closing tasks is proposed. These findings support the functional heterogeneity of the MP due to its selective activation in various tasks. This study proposes an important role for the MP in the generation of closing and lateral forces and also supports a role for the MP as being functionally heterogeneous.

▼ The length-tension relationship of the triceps surae (TS) can be altered by changing the knee joint position, ankle joint position or both. However, studies exploring the effect of muscle length on triceps surae (TS) neuromuscular properties have focused only on changes in knee joint position, affecting only two of the three muscle components of the TS. Thus, the purpose of this study is to compare the neuromuscular properties of the three TS muscles during plantar flexion contractions at two ankle joint positions, 20° dorsiflexed (DF) and 20° plantar flexed (PF). Maximal isometric voluntary strength (MVC), voluntary activation, and evoked contractile properties of the ankle plantar flexors were compared between both ankle joint positions. Additionally, motor unit discharge rates (MUDRs) of the soleus, medial (MG) and lateral (LG) gastrocnemii were sampled during plantar flexion contractions at 25, 50, 75 and 100% MVC using indwelling tungsten electrodes. Peak twitch torque and MVC were lower by ~70% and 61%, respectively, whereas maximal rate of torque relaxation was 39% faster in the PF compared with the DF position. Voluntary activation (~95%) was unaffected by changes in ankle joint position. LG MUDRs showed no differences between ankle joint positions, regardless of contraction intensity. Submaximal MG and soleus MUDRs showed no differences between the two ankle joint positions, however at 100% MVC both muscles had 9% and 20% higher rates in the DF position, respectively.

Maximal motor unit discharge rates of the medial and lateral gastrocnemeii of young males.

▼ The triceps surae is composed of the mono-articular soleus and the bi-articular gastrocnemeii. Mean maximal motor unit discharge rates (MUDRs) reported for the soleus (~16Hz) are lower than other limb muscles tested (Dalton et al., 2009). Because of differences in fibre-type and functional anatomy it is important to determine maximal MUDRs in the two heads of gastrocnemeii, as compared with the soleus, to fully understand the interplay of these three muscles for plantar flexion. The purpose of the study was to record maximal MUDRs of the medial (MG) and lateral gastrocnemeii (LG) in 9 recreationally active, young men (age 24.2 ± 1.6y; 81.3 ± 8.1kg; 180.3 ± 5.3cm). During 3 separate visits to the lab, participants performed a series of 6-8, 7s maximal voluntary isometric contractions (MVC) of the plantar flexors with a knee joint angle of 90 degrees, with 5 minutes of rest between contractions. Maximum voluntary activation of the plantar flexors using the interpolated twitch technique was calculated. Custom tungsten microelectrodes were inserted individually into the belly of the lateral and medial gastrocnemeii and gently manipulated during the contractions to sample from as many distinct motor units throughout the muscle as possible. Action potential trains were analyzed offline to calculate discharge rates for each identified motor unit. All subjects were capable of high % of voluntary activation (>96%) and achieved a mean maximal plantar flexor torque of 194.6 ± 57.1Nm. A total of 198 and 117 motor unit action potential trains were identified in the MG and LG, respectively. The mean maximal motor unit discharge rates were 22.7 ± 8.6Hz and 22.4 ± 8.1 Hz (Range: 5.5 - 64Hz) in the MG and LG, respectively, and were not significantly different from one another, p > 0.05. The coefficient of variation of discharge frequencies in the identified trains were 14.6 ± 1.4% and 14.3 ± 2.2% in the MG and LG respectively, and were not significantly different, p > 0.05. Maximal MUDRs in both heads of the gastrocnemeii are greater than in the soleus, but are not different from one another. Despite their similar roles in plantar flexion, the amount and degree of habitual activation (phasic vs. tonic) or their functional role (flexor vs. extensor) may account for motor unit discharge rate differences between the gastrocnemeii and soleus during plantar flexion actions.

▼ Electromyogram signals were recorded and analyzed from subjects with Amyotrophic Lateral Sclerosis. In contrast to routine needle clinical examinations, we used surface electrodes (High Density surface EMG, HDsEMG) in an attempt to show the feasibility of muscle assessment using a non-invasive approach. The study started by examining Fasciculation Potentials, a crucial electrodiagnostic feature of ALS. The feasibility of the proposed surface recording for their detection was soon established, so the fasciculation potentials were then further explored in order to understand the nature of their spontaneous discharges, when compared with regular
motor unit discharges.. Due to a lack of software applications to analyze the signals from HDsEMG electrodes, a number of new techniques were designed and implemented to extract these potentials from raw EMG, and to classify them based on their shapes. Taking advantage of advanced multi-channel recording technologies, we explored Fasciculation Potentials with respect to the ‘Innervation Zones’ of their sites of origin, where signs of muscle reorganization were observed. In addition to their non-invasive nature and their comfort for the patients, HDsEMGs were proposed as potentially more suitable in monitoring the progress of the disease. Preliminary results were presented on this theme. Muscle functional capacity was also assessed, by measuring the slope of the EMG-force relation. Abnormal EMG-force slopes in some of the ALS subjects were recorded. In addition to global EMG analysis, single
motor units were also extracted in a collaborative project which provided EMG decomposition outcome. We studied discharge behavior of single
motor units in hand muscles of ALS subjects, during isometric voluntary contractions. Overall, we concluded that HDsEMG can substitute for many electrodiagnostic practices in clinics, and can provide supplementary information about the muscle which is not attainable using single needle recording.

▼ This dissertation comprises five experimental studies that investigated the influence of electrical nerve stimulation on
motor unit discharge characteristics and mobility in young and older adults. Three studies evaluated the acute effects of electrical nerve stimulation and two were derived from an intervention that aimed to improve
motor function in older adults. In the first study, fine-wire electrodes were used to track single
motor unit activity in the biceps brachii of the left arm while electrical nerve stimulation was applied to the biceps brachii of the right arm. Although there was no change in the discharge characteristics of
motor units before, during, or after the application of electrical nerve stimulation, there was an increase in the number of
motor units detected during and after stimulation. The findings suggest that the activity of
motor units in the left elbow flexors during a voluntary contraction was modulated by electrical nerve stimulation applied to the right elbow flexors. The subsequent two studies examined the influence of age on fluctuations in force during voluntary and evoked contractions with hand and forearm muscles. There were fewer fluctuations in force during a wrist-extension task in older adults during electrical nerve stimulation than during a voluntary contraction, but there was no difference for young adults. Moreover, the greater force fluctuations exhibited by older adults during steady contractions were associated with worse performance on a test of manual dexterity and greater fluctuations in the estimated common synaptic input to
motor neurons during steady contractions. The final two studies examined the influence of an electrical nerve stimulation intervention applied to the calf muscles on
motor function in older adults across 6 weeks. The intervention improved mobility, but the time course of the adaptations varied across the different tests of mobility. Additionally,
motor unit discharge characteristics during steady contractions partially explained differences in mobility among older adults. This dissertation demonstrates the unique attributes of electrical nerve stimulation as an approach to modulate
motor function in older adults.

▼ Diabetes mellitus (DM) imparts vascular and metabolic stressors that cause damage and dysfunction to the human nervous system. The disorder associated with this dysfunction is termed diabetic polyneuropathy (DPN). Although DPN has been associated with muscle weakness and atrophy, the extent of its impacts on the neuromuscular system is not well understood. The five studies presented in my thesis investigated how DPN affects the neuromuscular system in humans, from the motor neuron to skeletal muscle contractile properties, using a combination of electromyography (EMG), dynamometry and magnetic resonance imaging (MRI) techniques.
The purpose of Studies 1 and 2 was to determine whether the neurogenic loss of motor units underlies the muscle weakness and atrophy associated with DPN, and to investigate how these changes may differ in an upper and lower limb muscle. I determined DPN patients feature reduced motor unit estimates (MUNEs) compared to controls, and progression of motor unit loss in DPN may follow a length-dependent pattern.
The purpose of Study 3 was to assess the stability of neuromuscular transmission in patients with DPN compared with healthy controls, using a novel set of electrodiagnostic parameters obtained via quantitative EMG. I determined DPN patients have less stable neuromuscular transmission, and the feature intermittent conduction failure at a relatively low contraction intensity.
The purpose of Study 4 was to investigate skeletal muscle contractile properties and morphology in DPN patients associated with the severity of muscle denervation. I determined DPN patients possess slowed muscle, with greater proportional amounts of non-contractile muscle tissue compared to controls.
The purpose of Study 5 was to explore the fatigability of DPN patients during a sustained, maximal voluntary contraction (MVC). I determined DPN patients have less endurance than controls, and their increased fatigability may be associated with neuromuscular transmission failure.
Overall these foundational explorations greatly expand our knowledge of how DPN can impact the neuromuscular system in humans. Furthermore, the studies contained within my thesis may help direct further useful studies and strategies to understand, and direct clinical support in those with DPN.

▼ This thesis describes experiments designed to
investigate how motor units in tibialis anterior (TA) were
recruited when electrical stimulation was applied over the TA
muscle belly versus the common peroneal nerve trunk. The data from
the first study (Chapter 2) showed that contractions were generated
predominantly by depolarizing motor axons, regardless of
stimulation site. The second study (Chapter 3) showed that single
pulses of stimulation delivered over the muscle belly recruited
motor units from superficial to deep as stimulation amplitude
increased, but single pulses delivered over the nerve trunk
recruited motor units evenly throughout the muscle, regardless of
stimulus amplitude. Contrary to the results of Chapter 3, the final
study (Chapter 4) provided preliminary evidence to suggest that
repetitive stimulation recruited motor units from superficial to
deep, regardless of stimulation site. In general, these findings
support the idea that where electrical stimulation is delivered
markedly affects how contractions are generated.

▼ The present thesis examined two general questions
regarding neuromuscular electrical stimulation (NMES): 1) How can
the delivery of NMES be optimised to enhance synaptic motor unit
recruitment via reflex pathways (central pathways) and 2) Can motor
unit recruitment through central pathways improve the
fatigue-resistance of NMES-evoked contractions in people with
chronic motor-complete spinal cord injury (SCI)? To address the
first general question, two sets of experiments were conducted with
people who were neurologically-intact (Chapters 2 and 3).
Information about how motor units were recruited was provided by
electromyographic responses evoked during NMES. The first two sets
of experiments tested the hypothesis that NMES delivered over the
nerve trunk (nNMES) would generate contractions of the plantar
flexors (Chapter 2) and knee extensors (Chapter 3) with greater
activity through central pathways compared with contractions of
equivalent amplitude evoked by NMES delivered over the muscle belly
(mNMES). Both hypotheses were confirmed, indicating that nNMES may
hold significant advantages over mNMES for rehabilitation, and in
particular for generating fatigue-resistant contractions. To
address the second general question, two sets of experiments were
conducted in people with chronic motor-complete SCI (Chapters 4 and
5). The first set of experiments tested whether contractions of the
paralysed plantar flexors evoked by mNMES would fatigue sooner, and
to a greater extent, compared with contractions of equivalent
amplitude generated by nNMES. This hypothesis was confirmed.
However, differences in fatigue-resistance between NMES sites were
dependent upon the contribution of central pathways (H-reflexes)
during the evoked contractions. When contractions were generated
only through successive motor axon activation (M-waves; peripheral
pathways), NMES site had no influence on fatigue-resistance. The
second set of experiments tested the hypothesis that contractions
of the paralysed plantar flexors evoked by nNMES using a short
pulse duration (50 µs) would fatigue sooner, and to a greater
extent, compared with contractions of equivalent amplitude evoked
by nNMES using a long pulse duration (1000 µs). Data collection for
this project continues, however initial data support our
hypothesis. In conclusion, activity through central pathways is
dependent upon NMES site, and holds promise for generating
fatigue-resistant contractions after SCI.

▼ Motor unit number estimation (MUNE) is an electrodiagnostic procedure used to estimate the number of MUs in a muscle. In this thesis, a new MUNE technique, called Automated MPS, has been developed to overcome the shortcomings of two current techniques, namely MPS and MUESA. This method can be summarized as follows. First, a muscle is stimulated with a train of constant intensity current pulses. Depending on various factors, one to three MUs activate probabilistically after each pulse, and several responses are collected. These collected responses should be divided into up to 2n clusters, such that each cluster represents one possible combination of n Surface-detected Motor Unit Potentials (SMUPs). After clustering the collected responses, the average response of each cluster is calculated, the outliers are excluded, and similar groups are merged together. Then, depending on the number of response set groups, a decomposition technique is applied to the response clusters to obtain the n constituent SMUPs. To estimate the number of MUs, the aforementioned process is repeated several times until enough SMUPs to calculate a reliable mean-SMUP are acquired. The number of MUs can then be determined by dividing the maximal compound muscle action potential (CMAP) size by the mean-SMUP size. The focus of this thesis was on using pattern recognition techniques to detect n SMUPs from a collected set of waveforms.
Several experiments were performed using both simulated and real data to evaluate the ability of Automated MPS in finding the constituent SMUPs of a response set. Our experiments showed that performing Automated MPS needs less experience compared with MPS. Moreover, it can deal with more difficult situations and detect more accurate SMUPs compared with MUESA.

▼ A multi-function bus transfer system comprising fast, in-phase and residual bus voltage transfer schemes is developed in the thesis. Bus residual voltage magnitude and phase angle are calculated by converting time domain components of a three phase system in an abc reference frame to dq0 components in a rotating reference frame using Park’s transformation equations. Residual bus voltage phase angle is then modelled by a Taylor’s series expansion to calculate the phasor angular position with reference to the alternate power supply ahead of time to enable synchronization of the two supplies. Simulations are performed to verify functionality and performance; and to deduce the characteristics of the respective schemes. The thesis then explores the feasibility of using the bus transfer system to stabilise power supply within a power generating plant auxiliary electrical reticulation when upstream electrical equipment failures occur; in particular focus is placed on the
unit boiler furnace draught system which would normally result in reduction of up to half of
unit generating capability if one set of the draught system is lost. Simulation results of case studies conducted provided practical understanding on the feasibility of using a bus transfer system, with fast bus transfer scheme being the most preferred method at 70 ms transfer time; which enables the forced draught fan
motor to be transferred within 2 s before the
unit begins to de-load. The thesis proposes a new reticulation configuration that allows the transfer of both forced and induced draught fan motors simultaneously while maintaining stable draught furnace pressure. The new configuration allows both fan motors to remain connected to the switchboard for up to 3 s before tripping the motors on under-voltage protection when upstream equipment failures occur, even though bus transfer can be executed in 70 ms or 520 ms using fast or in-phase transfer schemes respectively. The speed and minimum impact on the electrical system makes the fast transfer scheme the most preferred transfer method

▼ The surface electromyographic (sEMG) signals that originate from skeletal muscle electrical activity, are used clinically and experimentally to determine muscular behaviour, e.g. amplitude, area under the curve and onset of activity. Surface EMG signals are inevitably contaminated by noise and artefacts from the site between the skin and electrodes, non-target muscles and recording hardware. After recording, signal processing methods like filtering, are used in an attempt to determine the underlying active state of the muscle, portrayed by the motoneuron pool firing. As EMG is in fact a deformed representation of the actual muscle activity, processing is used to extract a more veracious description of the active muscle states. This study investigated the effects of random noise - which in practice resembles transducer noise -, and filtering on the simulation accuracy of short and long latency muscle stretch responses, extracted from simulated EMG signals. To obtain the deviation from the noiseless signals, a fiber potential model was developed to simulate the EMG surface potentials that used an existing motoneuron pool firing model by Schuurmans et al. 2009. The resulting EMGs were the muscle responses to stretch perturbations at different velocities and amplitudes combinations (1.5, 2, 3, 5 rad/s and 0.06, 0.10, 0.14 rad). Consecutively, the EMG signals were contaminated with different noise intensities (SNR: -1, 2, 5, 7, 9 dB) and then filtered with a \nth{3} order Butterworth low-pass filter, with cut-off frequencies between [1-200Hz]. Finally, the short- and long latency stretch responses areas were calculated and compared between the filtered noiseless and filtered noisy EMG signals, by calculating the difference between the values as a fraction of the value from the noiseless simulated signal. It was found that a signal-to-noise ratio of at least 5 dB with a 85Hz cut-off low-pass filter was necessary to keep the error below 10% maintaining M1 and M2 characteristics. It was also seen that M1 was more affected than M2 under the same amount of contamination, suggesting different spectral frequency contents between the stretch responses, and different underlying neuronal firing behaviour. The described signal-to-noise ratio thresholds and proposed cut-off frequencies resulting in acceptable signal error, can be used as a reference on accuracy of latency response simulations. The error courses provide information about the way error and signal are attenuated or preserved. Besides, the differences in error course comparing the two latency responses provides an insight into the difference in behaviour between the underlying reflex mechanisms. Apart from the findings the combination of adapted and developed model can be used in future research where noise-free surface potentials are required, and can be further developed to produce veracious EMG signals.

▼ Central sensitization describes a state of central nervous system hyperexcitability causing pain hypersensitivity. The impact of central sensitization on muscle structure and neurophysiology is unclear. This work aimed to determine the effect of experimentally induced central sensitization on muscle structure, motor recruitment, motor unit action potential characteristics and upper limb movement. Twenty healthy participants were randomized to receive topical capsaicin – to induce central sensitization acutely – or placebo. Ultrasound images, surface electromyography(sEMG), intramuscular electromyography (iEMG), and movement data were acquired before and after treatment. Capsaicin-induced sensitization resulted in significant changes in ultrasound image texture features, motor unit recruitment pattern (sEMG) and motor unit variability (iEMG). Movement analysis revealed capsaicin-induced changes in acceleration variability, suggesting changes in anterior horn cell excitability affecting efferent output. Overall, this thesis advances understanding of central sensitization manifestation, a requisite for developing quantitative criteria to diagnose central sensitization and chronic widespread pain.

▼ To effect movement, the central nervous system must appropriately coordinate the activities of pools of motoneurons (MNs), the cells which control muscle fibers. Sources of neural drive are often distributed to many MNs of a pool, and thus can synchronize the activities of targeted MNs. In this thesis, synchronization among MNs is used to investigate the strength, temporal progression, and anatomical distribution of neural drive to the hypoglossal
motor nucleus (HMN), which controls muscles of the tongue. The HMN is an ideal target for such an investigation because it processes a host of functionally diverse inputs, such as those related to breathing, speaking, and swallowing. Study 1 characterizes
motor unit (MU) synchronization within and across bellies of the human genioglossus (GG) muscle when MUs are activated by cortical drive (during voluntary tongue protrusion) or by automatic, brainstem-mediated drive (during rest breathing). We show that voluntary tongue protrusion synchronizes MU spike timing and firing rates within but not across bellies of the GG, whereas during rest breathing, MU firing rates are moderately synchronized both within and across muscle bellies. Study 2 documents respiratory-related synchronization of MU activities in muscles of the tongue and respiratory pump using an anesthetized rat model. The results of this study indicate that upper airway and respiratory pump MN pools share a low frequency respiratory-related drive, but that higher frequency (>8 Hz) synchronization is strongest in MU pairs of the chest-wall. Finally, Study 3 examines the potential for GG multi-
unit and single MU activities to be entrained by cortical input. We show that during voluntary tongue protrusion, cortical oscillations in the 15-40 Hz range weakly synchronize MU population activity, and that EEG oscillations in this range intermittently influence the spike timing of individual GG MUs. These studies are the first to characterize MU synchronization by different sources of neural input to the HMN and establish a broad foundation for further investigation of hypoglossal
motor control.

▼ Developmental nicotine exposure (DNE) is known to cause deleterious effects in neonatal mammals through nicotine's actions on nicotinic acetylcholine receptors (nAChRs). In this work, we studied how DNE altered the structure and function of the hypoglossal motoneurons (XIIMNs) over the first few days post-parturition. Previous work in XIIMNs demonstrated an increase in cellular excitability (Pilarski et al., 2011), alterations in synaptic transmission among respiratory-related neurons (Wang et al., 2006; Pilarski et al., 2012; Jaiswal et al., 2013), and a reduction in inspiratory drive currents in DNE animals (Pilarski et al., 2011). Here we show that the effects of DNE extend to alterations in the spike-timing precision and reliability of XIIMNs, as well as spike-frequency adaptation. Additionally, simple morphological analysis of XIIMNs following nicotine exposure in utero has revealed a reduction in soma cross-sectional area. We were interested in studying the complete morphology of XIIMNs following DNE to discern its effects on more complex morphological parameters. We advanced this research using a combination of techniques in thin brainstem slices of neonatal rats, including whole cell patch clamp recordings and immunohistochemistry of intracellularly labeled hypoglossal motoneurons. Furthermore, morphological analysis revealed significant differences in the complexity of the dendritic arborization, showing that neurons from DNE animals had shorter dendrites that branched less often. We also used computational analysis to gain insight into mechanisms that may underlie the changes in spike-timing precision and reliability. In a single cell model of XIIMNs, decreases in potassium-dependent conductances such as the calcium-activated potassium current could potentially replicate the alterations seen in vitro. Finally, we also did a systems-level study of the hyoglossus muscle, a tongue retractor, to determine the relation between tongue retraction force and
motor unit discharge characteristics. These experiments utilized adult, anesthetized rats to record single
motor units, whole muscle electromyography (EMG) activity and tongue retraction force during spontaneous breathing. We determined that during inspiration-related tongue retractions in low and high force conditions, recruitment of
motor units plays a crucial role in the control of tongue force output, whereas rate coding of single
motor units is present, but appears to play a lesser role. Overall, this study shows that DNE effects the input-output properties of XIIMNs, potentially through changes in intrinsic channel properties; DNE also alters XIIMN morphology, particularly dendritic arborization; and that organization of a tongue retractor muscle depends primarily on recruitment, but also rate coding, to increase force output.

▼ It is unknown whether differences in muscle quality or
motor unit (MU) behavior exist between normal weight (NW) and overweight (OW) children Purpose: Therefore, the purposes of this study were to examine potential differences in the first dorsal interosseous (FDI) between NW and OW for peak maximal voluntary contraction force (MVC force), muscle cross-sectional area (CSA), subcutaneous fat (sFAT), and echo intensity (EI), as well as parameters of
motor unit behavior, specifically
motor unit action potential size (MUAPSIZE) vs. recruitment threshold (RT), mean firing rate (MFR) vs. MUAPSIZE, and MFR vs. RT relationships, as well as EMG amplitude (EMGRMS[normalized as %max]). Methods: Anthropometric assessments were taken for body mass, BMI, and percent body fat (%BF). Ultrasonography scans of the FDI were completed in order to determine the muscle CSA, sFAT, and EI. MU behavior will be assessed during isometric muscle actions of the FDI at 20% and 50% MVC by the decomposition of the EMG signal from the surface of the skin. Results: OW was significantly greater than NW for mass (P < 0.001, NW = 30.96 ± 3.68 kg, OW = 41.37 ± 7.31 kg), BMI (P < 0.001, NW = 15.96 ± 0.94 kg/m2, OW = 21.22 ± 2.19 kg/m2), %BF (P < 0.001, NW = 17.01 ± 3.25%, OW = 31.01 ± 4.97%), sFAT (P < 0.001, NW = 2.19 ± 0.60 mm, OW = 3.71 ± 0.97 mm), and EI (P = 0.002, NW = 47.99 ± 6.01 AU, OW = 58.90 ± 10.63 AU). There were no differences between groups for CSA (P = 0.688, NW = 1.138 ± 0.146 cm2, OW = 1.162 ± 0.156 cm2), MVC force (P = 0.790, NW = 14.81 ± 3.49 N, OW = 14.43 ± 3.87 N) or MVC force/CSA (P = 0.697, NW = 13.00 ± 2.84 N/cm2, OW = 12.52 ± 3.60 N/cm2). However, NW had significantly greater lean CSA (CSA/EI) than OW (P = 0.040, NW = 0.024 ± 0.004 cm2/AU, OW = 0.020 ± .005 cm2/AU). For the MUAPSIZE vs. RT relationships, A terms were greater for NW (0.185 ± 0.12 mV) than OW (0.091 ± 0.05 mV) (P = 0.002), and for the MFR vs. MUAPSIZE relationships the B terms were less negative (P = 0.039) for the NW (-1.98 ± 1.36 pps/mV) than OW (-2.79 ± 1.46 pps/mV). There were no differences between groups for the slopes and y-intercepts from the MFR vs. RT relationships or for EMGRMS, however, slopes for the 50% MVC were less negative (-0.646 ± 0.18 pps/%MVC) than the slopes for the 20% MVC (-1.46 ± 0.64 pps/%MVC) and EMGRMS was greater for the 50% MVC (86.23 ± 37.7%) than the 20% MVC (32.27 ± 12.4%). Discussion: It is plausible that alterations in muscle architecture and/or stiffness as a result of greater intramuscular fat allowed the OW group to produce similar isometric MVC strength to the NW while possessing less lean CSA. This is supported by the finding that NW showed greater MUAPSIZES than OW at similar RTs and MFRs, which can be an indication of greater
motor unit and muscle fiber size. The MFR vs. RT relationships for both groups agreed with the onion skin scheme, and were similar to what has previously been reported in adults, however, EMGRMS for the 50% MVC was greater for children in the current study than what has been previously reported for…

▼ The purpose of this dissertation research project was to examine the role of impaired
motor unit firing behavior on force generation after a stroke. We studied the relationship between intrinsic motoneuron properties and inhibitory sensory pathways to deficient motoneuron activity in the vastus lateralis muscle after a stroke. Individuals with stroke often have deficits with force generation and volitional relaxation. Current models of impaired force output after a stroke focus primarily on the pathology within the corticospinal pathway because of decreased descending drive. Though this is an important aspect of deficient motoneuron output, it is incomplete because motoneurons receive other inputs that can shape
motor output. Because the motoneuron is the last site of signal integration for muscle contractions, using methods that study
motor unit activity can provide a window to the activity in the spinal circuitry. This research study utilized a novel algorithm that decomposed electromyography (EMG) signals into the contributions of the individual
motor units. This provided the individual firing instances for a large number of concurrently active
motor units during isometric contractions of the knee extensors. In the first aim, the association between the hyperemic response and
motor unit firing rate modulation to intermittent, fatiguing contractions was investigated. It was found that the magnitude of blood flow was lower for individuals with stroke compared to healthy controls, but both groups increased blood flow similarly in response to fatiguing contractions. This did not relate to changes in muscle fiber contractibility for the participants with stroke; rather, participants better able to increase blood flow showed greater modulation in
motor unit firing rates. To further investigate how ischemic conditions impact
motor unit output, the second aim used a blood pressure cuff to completely occlude blood flow through the femoral artery with the intent of activating inhibitory afferent pathways. We found that ischemic conditions had a greater inhibitory impact on
motor unit output for individuals with stroke compared to healthy controls, possibly because of hyper-excitable group III/IV afferent pathways. The final aim investigated how stroke related changes in the intrinsic excitability of the motoneurons impacted prolonged
motor unit firing during voluntary relaxation. A serotonin reuptake inhibitor was administered to quantify motoneuron sensitivity to neuromodulatory inputs. This study found that the serotonin reuptake inhibitor increased muscle relaxation and may have reduced persistent inward current contributions to prolonged
motor unit firing. In conclusion, while damage to the corticospinal tract is a major component to poor functionality, the intrinsic properties of the motoneuron and sensory pathways to the motoneuron pool are essential for understanding deficient
motor control after a stroke.

▼ A detailed understanding of the functions of the jaw muscles is essential for the description of normal function as well as how the jaw motor system accommodates to perturbations such as chronic pain states as well as surgical and prosthodontic interventions. While the functional properties of many jaw muscles, such as the masseter and temporalis muscles, and to a lesser extent the lateral pterygoid muscle, have been intensively investigated, the medial pterygoid (MPt) muscle has been much less well studied. The broad aims of this study were to: 1. to develop a methodology for recording activity from the MPt muscle from locations that have been verified by computed tomography (CT). 2. to identify the functional properties of single motor units (SMUs) recorded from the MPt muscle during standardized horizontal and vertical jaw movement tasks, and to determine whether movement velocity would affect motor unit activation. 3. to assess the relation between CT-verified locations and SMU activities to determine if there exists evidence for functional heterogeneity within the MPt muscle. Twenty participants (10 males and 10 females, mean age: 25 years old) performed 8 tasks: 1) resting, 2) swallowing, 3) ipsilateral movement, 4) contralateral movement, 5) protrusive movement, 6) opening–closing movement, 7) unilateral chewing with gum, 8) bilateral maximal clenching. The ipsilateral, contralateral, protrusive and opening – closing movement tasks were performed with a goal-directed, visual feedback system at slow and fast speeds, and each of these tasks was divided into BEFORE, OUT, HOLDING, RETURN and AFTER phases according to the movement trajectories and SMU analysis was conducted in the 4 goal-directed movements only. Electromyographic (EMG) activities of the right MPt were recorded in resting (in 8 of the 20 participants), swallowing (12/12), ipsilateral movement (16/20), contralateral movement (20/20), protrusion (19/20), opening – closing movement (11/20), chewing (20/20) and clenching (20/20) tasks. Increased EMG activity was consistently found in the OUT, HOLDING and RETURN phases of the contralateral and protrusive movement tasks, regardless of the actual movement direction. An increased activity in the RETURN phase of the ipsilateral movement task in most participants, together with the presence of increased activity in the OUT phase of contralateral task in all participants, indicates an important role for the MPt in the generation of a contralateral force vector. The presence of EMG activity in 8 participants during the resting task and increased EMG activity in the RETURN phase of the opening – closing task (i.e. closing movement) suggest its active role in supporting the lower jaw against gravity. The absence of EMG activity in the MPt in 9 participants during all 3 phases of opening – closing movement tasks indicates the certain compartments of the MPt may not be involved in the closing movement. Of the 60 SMUs that were identified in the 4 goal-directed movement tasks, thresholds could be identified in…

▼ 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.

▼ Sex hormones have in vitro effects on the nervous system. Furthermore, the effects of estradiol and progesterone metabolites have neurologic responses on the
motor system, evidenced by transcranial magnetic stimulation studies. Sex hormone effects on the nervous system may underlie some of the sex discrepancies seen in athletic performance, injury and cardiovascular events. Investigating sex differences is often complicated by hormonal oscillations across the menstrual cycle; therefore, the aims of this research were to investigate sex and menstrual cycle effects on the
motor and cardiovascular systems and the interaction of these two systems. In study 1,
motor unit (MU) recruitment patterns of the vastus medialis (VM) and vastus medialis oblique (VMO) were examined in males and females at five menstrual cycle phases. Initial discharge rate between the VM and VMO were different only in females. This VM/VMO discharge discrepancy was only evident in females during the ovulatory and mid luteal menstrual phases. Study 2 examined the frequency domain relationship of the VM and VMO MUs between the sexes and across the menstrual cycle. Males have 256% to 741% greater odds of having coherent MU oscillations in the common drive band than females, indicating a greater common rate modulation. Further evidence indicated MU pairs from the VMO and VM/VMO have 228% and 212% greater odds of having beta band oscillations than the VM, indicating control of those muscle groups has a common cortical modulation. Study 3 looked at changes in the autonomic nervous system across the menstrual cycle via heart rate variability analysis. Heart rate variability decreases from the follicular to the luteal phases of the menstrual cycle, indicating a decrease in parasympathetic control. In study 4, the time and frequency domain relationship between electrocardiogram and MU discharge timing was examined between the sexes and across the menstrual cycle. The time domain relationship indicated that both males and females have MU time lag centered between 20-25 milliseconds, with an apparent modulation of this relationship across the menstrual cycle. The findings from this series of studies indicate that there are differences between the sexes which are often modified by the menstrual cycle in females.

▼ 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.

▼ The purpose of this study is to develop an inlet duct design guideline with reduced length while maintaining the reliability of AHRI and ASHRAE standards and also it will reduce the risk of false testing failures and will lead to higher integrity of the testing results at different laboratories. Here we studied the fan performance of a 3-ton ECM blow through fan coil
unit for a number of parameters such as flow rate, inlet duct length,
unit capacity, fan type and
motor configuration. An additional objective of this work is to reduce the overall height of the testing setup (inlet duct + test
unit + outlet duct) by reducing this inlet duct length while maintaining the equivalent fan performance as of the minimum inlet duct length (standard case) as per ASHRAE 37.
