Abstract:
The response of muscle oxygen saturation, which is an index for the energy metabolism of muscles during walking in children, and its relationship to the physiological cost index, which indicates walking efficiency, are unknown. This study aimed to evaluate muscle oxygen saturation in lower extremity muscles during walking in children, its changes with age, and the relationship between the physiological cost index. The oxygen saturation was measured by the amount of change during a two-minute walk, and the physiological cost index was calculated from the change in heart rate before and after exercise and walking speed. Results were compared for each muscle, and the correlation between the two was examined. Changes in muscle oxygen saturation were greater in the lower leg muscles, significantly greater in the tibialis anterior at six to seven years, and in the gastrocnemius medial head at eight to ten years. The physiological cost index was significantly correlated with changes in muscle oxygen saturation in the tibialis anterior (r = 0.44, p < 0.001). The lower leg muscles were metabolically active in children’s gait, and their response varied with age. Moreover, the muscle oxygenation dynamics of the tibialis anterior may influence walking efficiency.

Abstract:
BACKGROUND: Walking is one of the important actions of the human body. For this purpose, the human brain communicates with leg muscles through the nervous system. Based on the walking path, leg muscles act differently. Therefore, there should be a relation between the activity of leg muscles and the path of movement. OBJECTIVE: In order to address this issue, we analyzed how leg muscle activity is related to the variations of the path of movement. METHOD: Since the electromyography (EMG) signal is a feature of muscle activity and the movement path has complex structures, we used entropy analysis in order to link their structures. The Shannon entropy of EMG signal and walking path are computed to relate their information content. RESULTS: Based on the obtained results, walking on a path with greater information content causes greater information content in the EMG signal which is supported by statistical analysis results. This allowed us to analyze the relation between muscle activity and walking path. CONCLUSION: The method of analysis employed in this research can be applied to investigate the relation between brain or heart reactions and walking path.

Abstract:
Information on muscle length is essential for the regulation of posture and movements. This informationis provided to the central nervous system by the sensory endings of the muscle spindles. The primary endings possess a dynamic sensitivity that is much greater jkfor small than for large amplitude changes. This sensitivity is due to the properties of certain intrafusal muscles fibres, the nuclear bag fibres, and their sensory terminals.

Abstract:
Muscle functional MRI (mfMRI) is an imaging technique that assess muscles’ activity, exploiting a shift in the T2-relaxation time between resting and active state on muscles. It is accompanied by the use of electromyography (EMG) to have a better understanding of the muscle electrophysiology; however, a technique merging MRI and EMG information has not been defined yet. In this paper, we present an anatomical and quantitative evaluation of a method our group recently introduced to quantify its validity in terms of muscle pattern estimation for four subjects during four isometric tasks. Muscle activation pattern are estimated using a resistive network to model the morphology in the MRI. An inverse problem is solved from sEMG data to assess muscle activation. The results have been validated with a comparison with physiological information and with the fitting on the electrodes space. On average, over 90% of the input sEMG information was able to be explained with the estimated muscle patterns. There is a match with anatomical information, even if a strong subjectivity is observed among subjects. With this paper we want to proof the method’s validity showing its potential in diagnostic and rehabilitation fields.

Abstract:
Muscle pathology can give much information to reach the diagnosis of neuromuscular disorders. Major pathological changes occurred in skeletal muscles include muscle fiber atrophy/hypertrophy, necrosis/regeneration, inflammation, myofibrillar disorganization, abnormal inclusions, and disruptions in cellular organelles. Physicians should be able to understand what each of these findings indicates. However, these are not always specific to a certain disease, and instead most of them are commonly found in many of muscle diseases. Thus, muscle pathological findings should be carefully interpreted under the given clinical settings.

Abstract:
This study aimed to clarify trunk muscle activity during jump header shooting and examine the immediate effects of trunk stabilization exercises on trunk muscle activity. Nineteen males who had played soccer for over 5 years were assigned to either the trunk stabilization exercise group or the control group. Muscle activity during jump header shooting was measured before and after intervention. The intervention in the trunk stabilization exercise group was trunk muscle training, whereas that in the control group was sitting. The phases of jump header shooting and the effects of the interventions were compared. In pre-intervention measurements, the internal oblique activity during the push-off phase and early floating phase was significantly greater than that during the late floating phase (p < 0.01667). In pre-intervention measurements, the muscle activity of the internal oblique increased from the push-off phase, prior to the increase in muscle activity of the rectus abdominis and external oblique, whereas the muscle activity of all abdominal muscles increased immediately after take-off. The trunk stabilization exercise intervention decreased the muscle activity of the erector spinae (p < 0.05). There seems to be a certain activation sequence in the abdominals during jump header shooting, and a single application of stabilization exercises could possibly reduce the activation of the back muscles.

Abstract:
The current study investigated the differences in muscle stiffness between older and young adults at rest and during contraction. We also evaluated the differences in muscle stiffness assessments using a myotonometer (MyotonPRO) and shear wave elastography (SWE). Twenty-two older adults (mean age, 66.6 ± 1.6 years) and 23 young adults (mean age, 66.6 ± 1.6 years) participated in this study. Muscle stiffness of the tibialis anterior (TA) and medial gastrocnemius (MG) muscles at rest and during contraction were measured using SWE and the MyotonPRO. The stiffness increase rate (SIR) was also calculated to determine the absolute stiffness difference. The mean muscle stiffness of the TA and MG muscles was significantly lower in older adults than in young adults at rest and during contraction (p < 0.05). Similarly, the SIR values of the TA and MG were significantly lower in older adults than in young adults (p < 0.05). Our results indicate that both instruments could be used to quantify muscle stiffness changes and serve as a cornerstone for assessing aging-related losses in muscle function. Stiffness measures may help exercise professionals to develop an in-depth understanding of muscle impairment at the tissue level.

Abstract:
Assessing muscle tone is an essential component of the diagnosis, prognosis, and treatment planning of developmental disabilities (DD) in children and is of great help in developing clinical diagnosis patterns. The purpose of this study was to investigate intra-rater and inter-rater reliability using the myotonometer, which is an assessment tool to measure muscle tone in children with DD. This study included 26 children diagnosed with DD. Two physical therapists measured the children’s muscle tone using a myotonometer. For all the muscles measured, reliability was determined using the intra-class correlation coefficient (ICC), the standard measurement error (SEM), and the minimal detectable change (MDC). The intra-rater reliability for all muscles was excellent (ICC = 0.75~0.78), except for the biceps brachii (ICC = 0.68). The inter-rater reliability was also excellent for all muscles (ICC = 0.75~0.95), and the SEM and MDC showed small measurement errors. Therefore, the intra-rater and inter-rater reliability of measurements by the myotonometer was found to be good or excellent. This suggests that the myotonometer is a tool that can objectively assess muscle tone, and it can be utilized in clinical practice to quickly and conveniently measure muscle tone in children with DD.

Abstract:
The pronator teres muscle is a major dynamic stabilizer of elbow valgus stress during throwing. This study aims to investigate pronator teres muscle activation during breaking ball pitching in baseball pitchers. Twelve male college baseball players with more than eight years of baseball experience were included in this study. A wireless surface electromyography (EMG) system was used to measure the activation of the forearm muscles and record EMG data during fastball and curveball pitching. Peak pronator teres muscle activation during curveball pitching was greater than that during fastball pitching (p = 0.03). There was no difference in the muscle activation of the other forearm muscles (p > 0.05). These results indicate that increased muscle activity in the pronator teres may contribute to stiffness and induce pronator teres syndrome or medial elbow injuries related to the overuse of the pronator teres, especially during curveball pitching. Controlling curveball throws contributes to player coaching and conditioning for the prevention of elbow joint disorders and pronator teres syndrome.

Abstract:
Smooth muscle is a machine consisting of working and supporting elements whose structure and 3D organization must be elucidated for the mechanics of shortening and tension generation to be understood. Based on longitudinal and serial transverse sections of rabbit portal vein it was suggested that the contractile elements of smooth muscle formed “mini-sarcomeres”, analogous to skeletal muscle, containing parallel arrays of 3-5 myosin filaments 1.6-2.2 um long. Observations at the light microscopic level were consistent with this idea. The past decade has seen little further investigation into the in situ ultrastructure of this or other smooth muscles, and the general applicability of these findings remains unknown. We have taken advantage of recent methodological advances, which can provide full 3D computer representations of cellular organization based on EM data, using guinea pig taenia coli muscle as a model system.Serial transverse sections (Fig 1) were used to generate 3D reconstructions of the organization of the myosin filaments and their relation to dense bodies, actin bundles, mitochondria and other organelles.

Abstract:
During the formation of skeletal muscle, muscle cell differentiation is induced by endogenous and exogenous stimuli which cause mononucleated cells committed to myogenic lineage called myoblasts to fuse into multinucleated myotubes. The molecular mechanisms underlying this process involve myogenic regulatory factors (MRFs) which are under tight regulation. Although transcriptional regulation plays an important role, it alone can not account for the high expression levels of MRFs. In this thesis, a facet of the post-trancriptional regulation of promyogenic factors, namely MyoD and Myogenin, through the RNA-Binding Protein HuR is investigated. The presented studies show that HuR, which specifically binds to the AU-rich elements (AREs) in the 3’UTR of the aforementioned messages and stabilizes them, is cleaved during myogenesis by caspases at the site D226 which is in the HNS region. This domain normally mediates the shuttling of HuR via the import receptor Transportin 2 (Trn2); however, during myogenesis HuR is translocated to the cytoplasm where it is cleaved to generate HuR-CP1. This cleavage product then competes with HuR for binding to Trn2 which in turn prevents HuR from relocating to the nucleus and results in its cytoplasmic accumulation where it can further stabilize of the promyogenic factors and allow for muscle differentiation to proceed. Since HuR-CP1 competes with HuR for Trn2, it was interesting to examine other ligands that HuR-CP1 and HuR-CP2, the complementary cleavage product, could bind to. To this end a pull-down experiment was performed with these isoforms and extensive lists of partner proteins obtained were then compared. A biotinylation experiment was also performed with MyoD and myogenin 3’UTRs to search for RNA-Binding Proteins that could be partners of HuR or its cleavage products. Due to the time restraint, the associations from these preliminary data have not yet been validated; however an analysis of the data, shows hnRNPK, which associates with Hu proteins and antagonizes their role in neurogenesis, to bind all three isoforms as well as MyoD and myogenin 3'UTR. It would therefore be interesting to investigate some of the proteins identified in these experiments, validate the associations, and assess the roles they play, if any, during myogenesis.
Durant la formation des muscles, des stimulis endogènes et exogènes induisent la différentiation de cellules mononuclées en cellules de la lignée myogénique qui vont ensuite fusionner pour former des fibres musculaires multinuclées. Les mécanismes moléculaires entourant ce processus mettent en jeu des facteurs régulateurs de la myogenèse, les MRFs, qui sont eux-mêmes très finement contrôlés. Bien que la transcription joue un rôle très important dans ce processus, seule, elle ne peut pas maintenir le niveau élevé d'expression des MRFs. Dans ce mémoire j'étudie un aspect de la régulation post-transcriptionnelle, notamment le rôle de HuR, une protéine qui se lie spécifiquement aux éléments riches en AU (ARE) dans les régions 3’non traduites (3’UTRs) des ARN messagers comme MyoD et myogenin. Mes expériences démontrent que durant la différentiation musculaire, HuR est clivée par les caspases au niveau de l'acide aminé aspartate (D) 226 qui se situe dans un domaine important pour le mouvement de HuR du noyau au cytoplasme et l'inverse, avec l'aide de l'importine Transportin 2 (Trn2). Le déclenchement de la différentiation suscite le mouvement de HuR vers le cytoplasme, un évènement suivi par son clivage qui génère deux produits HuR CP2 et HuR-CP1. Ce dernier ayant une affinité pour Trn2, rentre en compétition avec HuR et prévient ainsi son mouvement vers le noyau. L'accumulation de HuR dans le cytoplasme permet donc de stabiliser les ARNm pro-myogéniques plus longtemps et de favoriser la différentiation. L'association de HuR-CP1 avec Trn2 m'a aussi menée à étudier les partenaires potentiels des produits de clivage par rapport à HuR. Mes expériences de Pull down ont généré de longues listes que j'ai pu comparer. Dans le but de voir si les protéines qui s'associent aux messages MyoD et myogenin se lient à HuR ou aux produits de clivage j'ai fait une expérience de biotinylation du 3’UTR des messages mentionnés. Malgrès le fait de ne pas avoir eu le temps de vérifier ces associations, j'ai pu repérer une protéine hnRNPK qui a était étudiée dans la neurogenèse et qui antagonise l'effet de protéines Hu dans ce processus. Cette protéine semble s'associer à HuR, les produits de clivages et les messages. Cela étant donné, je pense que ce serait intéressant de valider cette association en plus des autres mentionnées dans mon mémoire et d'étudier leurs importances dans la myogenèse.

Abstract:
During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). In addition, during the acquisition of EMG signals, technical factors are introduced (measurement equipment origin). The aim of this dissertation was to develop and evaluate methods to estimate physiological properties of the muscles using multichannel surface EMG (MCsEMG) signals. In order to obtain accurate physiological estimates, a method for automatic signal quality estimation was developed. The method’s performance was evaluated using visually classified signals, and the results demonstrated high classification accuracy. A method for estimation of the muscle fibre conduction velocity (MFCV) and the muscle fibre orientation (MFO) was developed. The method was evaluated with synthetic signals and demonstrated high estimation precision at low contraction levels. In order to discriminate between the estimates of MFCV and MFO belonging to single or populations of motor units (MUs), density regions of so called spatial distributions were examined. This method was applied in a study of the trapezius muscle and demonstrated spatial separation of MFCV (as well as MFO) even at high contraction levels. In addition, a method for quantification of MU synchronisation was developed. The performance on synthetic sEMG signals showed high sensitivity on MU synchronisation and robustness to changes in MFCV. The method was applied in a study of the biceps brachii muscle and the relation to force tremor during fatigue. The results showed that MU synchronisation accounted for about 40 % of the force tremor. In conclusion, new sEMG methods were developed to study muscle function and motor control in terms of muscle architecture, muscle fibre characteristics, and processes within the central nervous system.

Abstract:
Motor Unit (MU) innervation zones (IZs) localization is an important step in several clinical and non-clinical applications including 1) Acquisition of sEMG signal for accurate estimation of its amplitude and other parameters by avoiding placing the electrodes on IZs, 2) Accurate estimation of the EMG-Force relationship, 3) Effective injection of Botulinum Toxin in Post-stroke Spasticity near the IZs, and 4) Guiding the obstetricians to perform episiotomy during child delivery by avoiding cutting near the IZs of External Anal Sphincter (EAS) muscle. The minimal invasive way to identify the location of the IZs generally for any muscle and specifically for EAS muscle is to use multi-channel EMG signals. MU IZs can be detected from the multi-channel sEMG signals, for a fusiform muscle if the signal is acquired with an array of electrodes placed parallel to the muscle fibers, using digital signal and image processing algorithms. As most of the signal processing algorithms work on an adequate quality of the signal, thus before detecting the innervation zone it is made sure that the signal is of good quality. For this purpose, a method based on statistical thresholding of various parameters is proposed to detect the bad channels in the sEMG signals. If the number of the bad consecutive channels are more than 2 then it is suggested to acquire the signal again, otherwise each bad channel is approximated by the interpolation of its neighbor channels. As some background noise is always acquired with the EMG signal so further image enhancement techniques are used to enhance the MUAP propagation region in the spatio-temporal images and suppress the background noise. The MUAP pattern is then detected in the spatio-temporal sEMG images using multi-scale Hessian based filtering and the corresponding MU IZs are identified as the starting point of propagation of the MUAP. A software is also developed which can be used to visualize the signals acquired from EAS, detect and display the IZs and more importantly compute and display the histogram of the IZs and generate reports which will help the obstetrician while performing episiotomy during child delivery to avoid cutting vulnerable regions that may lead to fecal incontinence at later age.

Abstract:
Manufacturing and construction workers undertake physically strenuous activities increasing the risk of health problems, disability, and sick leave, leading to lower job attractiveness and job candidate scarcity. In the EU, up to 44 million workers are affected by workplace-related musculoskeletal disorders (MSDs), representing a total annual cost of more than €240 billion. Exoskeleton use could alleviate muscle peak loads and reduce the risks of injury of workers. This work is related to the INTERREG's project "EXSCALLERATE" which aimed to accelerate the adoption of exoskeletons among SMEs. This research presents a comparative study of using exoskeletons by workers while performing different tasks related to their job. The tests evaluate the advantages of using exoskeletons in reducing human muscle activity, thereby, reducing the fatigue and tiredness. The study uses two commercially available exoskeletons, (1) upper body exoskeleton known as Eksovest and (2) lower body exoskeleton known as LegX. For upper body, the study performed drilling tasks at shoulder height and roof drilling positions, whereas, for the lower body, virtual chair position and squatting positions are tested which involved frequent bending of knees. Besides, the experiments based on accuracies of the data collection techniques and compare three volunteer’s body muscle data acquired by EMG sensor. From these comparisons, it is found that the muscle activity can be reduced up to 60% by using these exoskeletons, hence, increasing the work life of the workforce. The results of this study will help create awareness among SMEs towards the adoption of exoskeletons.

Abstract:
Apesar da prática da Ginástica Acrobática ser apontada por alguns estudos como um estímulo eficiente em gerar adaptações neuromusculares associadas a uma melhora no controle postural, até o presente momento nenhum estudo investigou o comportamento das oscilações posturais de ginastas da Ginástica Acrobática frente à manipulação de informações sensoriais, como por exemplo, na presença de informações táteis adicionais. Além disso, um grande número de estudos tem mostrado um aumento nas oscilações posturais em função da fadiga muscular. No entanto, não há na literatura investigações acerca dos efeitos da fadiga muscular sobre controle postural de ginastas da Ginástica Acrobática. Visto que diferentes tipos de treinamento físico, especialmente aqueles que requerem ações rápidas e habilidosas envolvendo equilíbrio e orientação corporal, induzem melhoras no controle postural, a hipótese levantada nesse estudo foi de que os ginastas da Ginástica Acrobática deveriam apresentar, após um protocolo de indução de fadiga muscular, um aumento nas oscilações posturais menos acentuados em comparação a não ginastas (i.e. um menor efeito da fadiga muscular sobre as oscilações posturais). Dessa forma, o objetivo desse estudo foi comparar, entre ginastas da Ginástica Acrobática (grupo GYN) e não ginastas (grupo CTRL), os efeitos da fadiga muscular dos flexores plantares do tornozelo sobre o controle postural, durante tarefas de postura unipodal com e sem a presença de informações táteis adicionais (i.e. com e sem contato do dedo indicador com uma superfície externa). Além disso, foi utilizada eletromiografia (EMG) de superfície de músculos do membro inferior e do tronco para avaliar mais profundamente as adaptações do sistema neuromuscular em função da instalação da fadiga. Os resultados indicaram que, para ambos os grupos GYN e CTRL, a fadiga muscular causou aumento das oscilações posturais, enquanto o toque causou diminuição das mesmas. No entanto, para o grupo CTRL (mas não para o grupo GYN) o efeito da fadiga parece ser dependente da condição de toque, visto que quando informações táteis adicionais estiveram presentes, o efeito da fadiga sobre as oscilações posturais foi atenuado. Apesar das oscilações posturais terem sido semelhantes entre os grupos GYN e CTRL, a análise dos sinais de EMG indicou que o grupo GYN utilizou menores níveis de ativação do músculo tibial anterior (ou ativações menos frequentes), assim como diferentes distribuições espectrais dos sinais de EMG provenientes do gastrocnêmio medial, bíceps femoral e do reto abdominal durante a tarefa de equilíbrio unipodal, independentemente da condição de fadiga ou de toque
Although Acrobatic Gymnastics practice has been considered effective in generating neuromuscular adaptations associated with postural control improvements, to date no study has investigated the behavior of postural sway of gymnasts of Acrobatics Gymnastics in response to the manipulation of sensory information such as the addition of tactile sensory cues. Moreover, a large number of studies have shown increased postural oscillations in response to muscle fatigue. However, no investigation has addressed the effects of muscle fatigue on the postural control of gymnasts of Acrobatics Gymnastics. As postural control is improved by different types of physical training, particularly those requiring skilled and fast actions, the hypothesis saised in this study was that gymnasts of Acrobatics Gymnastics would be less prone to fatigue-induced postural instabilities, thereby showing a smaller effect of muscle fatigue on postural sway. Therefore, the aim of this study was to compare the effects of plantar flexor muscle fatigue on the control of single leg stance between gymnasts of Acrobatics Gymnastics (GYN group) and non-gymnasts (CTRL group), during postural tasks performed with and without additional tactile information due to contact of the index finger with an external surface. Additionally, surface EMG of the lower limb and trunk muscles was used to further evaluate the fatigue-induced adaptations on the neuromuscular system. The results indicated that, for both GYN and CTRL groups, muscle fatigue caused an increase in postural sway, while the touching an external surface decreased it. However, for the CTRL group (but not for the GYN group) the effect of fatigue seems to be dependent on the touch condition, as the effect of fatigue on postural sway was attenuated in the presence of additional tactile information. Although postural sway parameters were similar between the GYN and CTRL groups, analysis of the EMG signals indicated that the GYN group used lower levels of tibialis anterior muscle activation (or less frequent activations), as well as different spectral distributions of the EMG signals from gastocnemius medialis, biceps femoris and rectus abdominis during the unipodal postural task, regardless of the fatigue or touch condition

Abstract:
This study, investigated the accuracy, practicality, and sensitivity of several different methods of calculating muscle forces during functional activities in humans. The upper extremity dynamic system was chosen, where the movement flexion / extension elbow joint was studied. The redundant mechanisms were solved using optimization criteria with and without models of individual muscles according to their active and passive properties. Exploration of the control problem for the redundant elbow system was performed using muscle models with and without tendon and activation dynamics. Comparisons with known movements solved by inverse dynamics approach and optimization techniques, provided similar results across to all optimization criteria. Moreover, if muscle models with active and passive properties are included in these analyses, it is relatively easy to calculate muscle forces of both agonists and antagonists. These approaches may be used to provide input data for dynamic FEM stress analysis of bones and bone-implant systems.

Abstract:
There is concern associated with the duration that a microsurgeon operates. Muscle fatigue can present itself over time and adversely affect the surgeon’s ability to perform appropriately during lengthy procedures. This paper explores a new method of analyzing muscle fatigue within the muscles predominantly used during micro-surgery. The captured Electro-MyoGraphic (EMG) data retrieved from these muscles are analyzed for any defining patterns relating to muscle fatigue. The analysis consists of dynamically embedding the EMG signals from a single muscle channel into an embedded matrix. The muscle fatigue is determined by defining its entropy characterized by the singular values of the Dynamical Embedded (DE) matrix. The paper compares this new method with the traditional method of using mean frequency shifts in EMG signal’s power spectral density. Linear regressions are fitted to the results from both methods, and the coefficient of variation of both their slope and point of intercept are determined. It is shown that the complexity method is more robust in that the coefficient of variation for the DE method has lower variability than the conventional method of mean frequency analysis.

Abstract:
The main functions of the human musculoskeletal system are to sustain loads and provide mobility. Bones and joints themselves cannot produce movement; skeletal muscles provide the ability to move. Knowledge of muscle forces during given activities can provide insight into muscle mechanics, muscle physiology, musculoskeletal mechanics, neurophysiology, and motor control. However, clinical examinations or instrumented strength testing only provides information regarding muscle groups. Musculoskeletal models are typically needed to calculate individual muscle forces.

Abstract:
Abstract Cerebrovascular accidents like a stroke can affect lower limb as well as upper extremity joints (i.e., shoulder, elbow or wrist) and hinder the ability to produce necessary torque for activities of daily living. In such cases, muscles’ ability to generate force reduces, thus affecting the joint’s torque production. Understanding how muscles generate force is a key element to injury detection. Researchers developed several computational methods to obtain muscle forces and joint torques. Electromyography (EMG) driven modeling is one of the approaches to estimate muscle forces and obtain joint torques from muscle activity measurements. Musculoskeletal models and EMG-driven models require necessary muscle-specific parameters for the calculation. The focus of this research is to investigate the EMG-driven approach along with an upper extremity musculoskeletal model to determine muscle forces of two major muscle groups, biceps brachii and triceps brachii, consisting of seven muscle-tendon units. Estimated muscle forces were used to determine the elbow joint torque. Experimental EMG signals and motion capture data were collected for a healthy subject. The musculoskeletal model was scaled to match the geometric parameters of the subject. First, the approach calculated muscle forces and joint moment for simple elbow flexion-extension. Later, the same approach was applied to an exercise called triceps kickback, which trains the triceps muscle group. Individual muscle forces and net joint torques for both tasks were estimated.

Abstract:
Abstract This paper presents an efficient criterion for solving the redundancy of the muscle recruitment problem in inverse dynamics of musculo-skeletal systems. It is a minimum fatigue criterion that is formulated as a min/max optimization problem. The criterion is briefly reviewed in comparison to other criteria and its implementation for large and complex system, such as the human body, is explained in detail. The optimization problem is solved numerically by means of linear programming, providing a very efficient, final algorithm. It is shown that special care must be taken of systems with groups of sub-maximally loaded muscles and methods to deal with this automatically are presented. The algorithms are implemented into a software system called AnyBody, and examples involving up to 100 muscles are demonstrated. Even models of this size are solved in fractions of a second for a single time step on a standard PC.

Abstract:
The flexible multibody simulation [9] approach can be used in a wide variety of engineering applications. In a previous study of authors [1], flexible multibody simulation approach was used to estimate strains during walking at tibial midshaft. In the previous study, simple muscle models were used in conjunction with a flexible tibia model based on magnetic resonance images (MRI). This study is an extension of the previous developments [1], [2] demonstrating the potential of model improvement by introducing hybrid muscle models, along with the flexible tibia based model on computed tomography (CT). The computed tomography technique allows for the accounting of inhomogeneous density and elasticity in the flexible bone model comparing to magnetic resonance which do not provide any information on material properties. Hybrid muscle configuration used in this study consists of electromyography (EMG) actuated simple muscles configured with open-loop control for soleus, tibialis anterior, gastrocnemius and rectus femoris muscles and closed-loop Hill-based muscles [13] for the remaining lower body muscles. Strain results introduced in the study show good correlation with previous studies.

Abstract:
Soft robotics integrates compliant actuators and sensors that expand design possibilities beyond classic robotics based on rigid modular components. In particular, deformable elastomer-based actuators used in soft robots, such as air-muscles, offer the possibility of having large numbers of embedded degrees of freedom. However, air-muscles fatigue life and strain capability call for a tradeoff, limiting their practical use in demanding applications such as physical rehabilitation, medical robotics, and mobile robots. This paper presents the design of a durable high-strain air-muscle composed of a silicone tube and an axially elastic sleeve (radially rigid), which integrates a flexible Dielectric Elastomer (DE) position sensor. The uniformity of the sleeve, by opposition to usual braids, makes for a reinforcement without local stresses that cause membrane failure. Designed based on fatigue failure principles, this air-muscle withstands 145 000 cycles at 50 % elongation, which demonstrates its potential as a durable high-strain actuator. Performance maps of the air-muscle confirm good linearity between force, pressure and strain and demonstrate bi-directional force capability. Furthermore, the integration of a DE sensor allows for accurate position control of the air-muscle (0.17 mm), making the air-muscle/sensor unit a relevant building block for complex soft robotics systems. The all-polymer high-strain actuator/sensor unit proves to be accurate and durable as well as cost-effective, thus making it ideal for soft robotics applications requiring large numbers of actuators and integrated sensing.

Abstract:
An understanding of the muscle power contributions to the crank and limb segments in recumbent pedaling would be useful in the development of rehabilitative pedaling exercises. The objectives of this work were to (i) develop a forward dynamic model to simulate low-power pedaling in the recumbent position, (ii) use the model to quantify the power contributions of the muscles to driving the crank and limb segments, and (iii) determine whether there were differences in the muscle power contributions required to simulate recumbent pedaling at three different pedaling rates. A forward dynamic model was used to determine the individual muscle excitation amplitude and timing to drive simulations that best replicated experimental kinematics and kinetics of recumbent pedaling. The segment kinematics, pedal reaction forces, and electromyograms (EMG) of 10 muscles of the right leg were recorded from 16 subjects as they pedaled a recumbent ergometer at 40, 50, and 60 rpm and a constant 50 W workrate. Intersegmental joint moments were computed using inverse dynamics and the muscle excitation onset and offset timing were determined from the EMG data. All quantities were averaged across ten cycles for each subject and averaged across subjects. The model-generated kinematic and kinetic quantities tracked almost always within 1 SD of the experimental data for all three pedaling rates. The uniarticular hip and knee extensors generated 65 percent of the total mechanical work in recumbent pedaling. The triceps surae muscles transferred power from the limb segments to the crank and the bi-articular muscles that crossed the hip and knee delivered power to the crank during the leg transitions between flexion and extension. The functions of the individual muscles did not change with pedaling rate, but the mechanical energy generated by the knee extensors and hip flexors decreased as pedaling rate increased. By varying the pedaling rate, it is possible to manipulate the individual muscle power contributions to the crank and limb segments in recumbent pedaling and thereby design rehabilitative pedaling exercises to meet specific objectives.

Abstract:
Both for civilian and military applications, tracking and identifying muscle fatigue—usually caused by continuous, repetitive motion over a finite period of time—is of great importance. The muscle fatigue process is very difficult to track due to its hidden nature. Invasive procedures are often needed to measure fatigue. Here, easily obtainable noninvasive kinematic measurements are used to extract muscle fatigue related trends associated with a sawing motion. The methodology is derived from dynamical systems based fatigue identification in engineered systems. Ten right-handed subjects perform sawing motion until voluntary exhaustion. Three sets of joint kinematic angles are measured from the elbow, wrist, and shoulder. Fatigue is identified in two steps: (1) phase space warping based feature vectors are estimated from kinematic time series; and (2) smooth orthogonal decomposition (SOD) is used to extract fatigue related trends from these features. SOD-based trends are compared against independently obtained fatigue markers estimated from the mean and median frequencies of electrography (EMG) signals of individual muscles. SOD-based trends from elbow and shoulder kinematics adequately capature fatigue in the triceps muscle estimated from the EMG measurements. These same kinematic angles show little fatigue information in the flexor/extensor carpi radialis (not directly engaged in sawing motion). The methodology used here shows great potential in tracking individual muscle fatigue evolution using only motion kinematics data.

Abstract:
The original objectives were: A. To determine the critical embryonic age for monochromatic green light stimulation. B. To follow the ontogeny of embryos exposed to monochromatic green light vs. darkness. C. To investigate the effects of monochromatic green light illumination on myoblast and fiber development in the embryo. D. To investigate the stimulatory effect of light combinations during embryo and post-hatch periods on growth and meat production. E. To evaluate the direct effect of monochromatic green light on cultured embryonic and adult myoblasts. The overall purpose of this study was to investigate the effect of monochromatic light stimuli during incubation period of broilers on muscle development and satellite cell myogenesis. Based on previous studies (Halevy et al., 1998; Rozenboim et al., 1999) that demonstrated the positive effects of green-light illumination on body and muscle growth, we hypothesized that monochromatic light illumination accelerates embryo and muscle development and subsequently enhances muscle growth and meat production. Thus, further decreases management costs. Under the cooperation of the laboratories at the Hebrew University of Jerusalem and University of Washington we have conducted the following: 1. We have established the critical stage for exposure to green monochromatic light which has the maximal effect on body and muscle growth (Objective A). We report that embryonic day 5 is optimal for starting illumination. The optimal regime of lighting that will eliminate possible heat effects was evaluated by monitoring egg core temperature at various illumination periods. We found that intermitted lighting (15 min. on; 15 min. off) is optimal to avoid heat effects. 2. We have evaluated in detail gross changes in embryo development profile associated to green light stimuli vs. darkness. In addition, we have investigated the stimulatory effect of light combinations during embryo and post-hatch periods on body and muscle growth (Objective B,D). 3. We have studied the expression profile of muscle regulatory proteins during chicken muscle cell differentiation in cultures using newly developed antibodies. This study paved the way for analyzing the expression of these proteins in our photo stimulation experiments (Objective C). 4. We have studied the pattern ofPax7 expression during myogenesis in the posthatch chicken. Experimental chick pectoralis muscles as well adult myoblast cultures were used in this study and the results led us to propose a novel model for satellite cell differentiation and renewal. 5. The effects of monochromatic green light illumination during embryogenesis have been studied. These studies focused on fetal myoblast and satellite cell proliferation and differentiation at pre- and posthatch periods and on the effects on the expression of muscle regulatory proteins which are involved in these processes. In addition, we have analyzed the effect of photo stimulation in the embryo on myofiber development at early posthatch (Objective C). 6. In follow the reviewers' comments we have not conducted Objective E. The information gathered from these studies is of utmost importance both, for understanding the molecular basis of muscle development in the posthatch chicks and for applied approach for future broiler management. Therefore, the information could be beneficial to agriculture in the short term on the one hand and to future studies on chick muscle development in the embryo and posthatch on the other hand.

Abstract:
Review question / Objective: Erector spinae plane block (ESPB) has been employed in arthroscopic shoulder surgery (ASS) as an alternative novel interfacial plane block. However, its analgesic efficacy is still controversial. Whether ESPB could improve analgesic efficacy in ASS is what the current meta-analysis seeks to find out. Information sources: We searched different databases including the Cochrane Library, PubMed, Embase, and Web of Science from inception to November 29, 2022, using medical subject headings (MeSH) and free-text terms without language restrictions. The primary purpose of searching was for the selection of RCTs for meta-analysis but also to avoid unplanned duplication and compare reported review methods from other systematic reviews. The following search terms were used for the search of each database: “arthroscopic shoulder surgery”, “shoulder surgery”, “total shoulder arthroplasty”, “shoulder arthroscopy”, and “erector spinae plane block”, “erector spinae muscle”. We also searched for grey literature by supplementary hand searching.

Abstract:
The proposed research was directed at determining the activation/binding domains and gene regulation of the PBAN-R’s thereby providing information for the design and screening of potential PBAN-R-blockers and to indicate possible ways of preventing the process from proceeding to its completion. Our specific aims included: (1) The identification of the PBAN-R binding domain by a combination of: (a) in silico modeling studies for identifying specific amino-acid side chains that are likely to be involved in binding PBAN with the receptor and; (b) bioassays to verify the modeling studies using mutant receptors, cell lines and pheromone glands (at tissue and organism levels) against selected, designed compounds to confirm if compounds are agonists or antagonists. (2) The elucidation ofthemolecular regulationmechanisms of PBAN-R by:(a) age-dependence of gene expression; (b) the effect of hormones and; (c) PBAN-R characterization in male hair-pencil complexes. Background to the topic Insects have several closely related G protein-coupled receptors (GPCRs) belonging to the pyrokinin/PBAN family, one with the ligand pheromone biosynthesis activating neuropeptide or pyrokinin-2 and another with diapause hormone or pyrokinin-1 as a ligand. We were unable to identify the diapause hormone receptor from Helicoverpa zea despite considerable effort. A third, related receptor is activated by a product of the capa gene, periviscerokinins. The pyrokinin/PBAN family of GPCRs and their ligands has been identified in various insects, such as Drosophila, several moth species, mosquitoes, Triboliumcastaneum, Apis mellifera, Nasoniavitripennis, and Acyrthosiphon pisum. Physiological functions of pyrokinin peptides include muscle contraction, whereas PBAN regulates pheromone production in moths plus other functions indicating the pleiotropic nature of these ligands. Based on the alignment of annotated genomic sequences, the primary and secondary structures of the pyrokinin/PBAN family of receptors have similarity with the corresponding structures of the capa or periviscerokinin receptors of insects and the neuromedin U receptors found in vertebrates. Major conclusions, solutions, achievements Evolutionary trace analysisof receptor extracellular domains exhibited several class-specific amino acid residues, which could indicate putative domains for activation of these receptors by ligand recognition and binding. Through site-directed point mutations, the 3rd extracellular domain of PBAN-R was shown to be critical for ligand selection. We identified three receptors that belong to the PBAN family of GPCRs and a partial sequence for the periviscerokinin receptor from the European corn borer, Ostrinianubilalis. Functional expression studies confirmed that only the C-variant of the PBAN-R is active. We identified a non-peptide agonist that will activate the PBAN-receptor from H. zea. We determined that there is transcriptional control of the PBAN-R in two moth species during the development of the pupa to adult, and we demonstrated that this transcriptional regulation is independent of juvenile hormone biosynthesis. This transcriptional control also occurs in male hair-pencil gland complexes of both moth species indicating a regulatory role for PBAN in males. Ultimate confirmation for PBAN's function in the male tissue was revealed through knockdown of the PBAN-R using RNAi-mediated gene-silencing. Implications, both scientific and agricultural The identification of a non-peptide agonist can be exploited in the future for the design of additional compounds that will activate the receptor and to elucidate the binding properties of this receptor. The increase in expression levels of the PBAN-R transcript was delineated to occur at a critical period of 5 hours post-eclosion and its regulation can now be studied. The mysterious role of PBAN in the males was elucidated by using a combination of physiological, biochemical and molecular genetics techniques.
