Full textExistence of a full thickness rotator cuff tear is really common in the general population with prevalence near 20%. This prevalence increases with age as the existence of asymptomatic cuff tear. How can we explain that tendinous injuries do not cause symptoms?The essential action of the rotator cuff is to center the humeral head in front of the glenoid cavity in order to enable a maximal action of the deltoid muscle. This centering action is still possible in case of supra-spinatus tendon tear and the shoulder can keep a satisfying function if equilibrium is conserved between the anterior cuff (Sub-scapularis muscle) and the posterior cuff (Infra-spinatus and Teres Minor muscles). How can we explain that supra-spinatus tears, even small, can induce functional impairment of the shoulder?There is a real dissociation between anatomy and clinic for the rotator cuff tears and the clinical expression of cuff tears is multifactorial and variable. It depends of the size of the tear and its evolution, of the existence of a sub-acromial bursitis and of the existence of a long head biceps tendinopathy.Comparison between symptomatic and asymptomatic subjects which present a rotator cuff tear permitted to show the importance of the periscapular muscles for the understanding of the rotator cuff tears. Indeed, the function of the periscapular muscles is to orientate the scapula and the glenoid during arm movements. When periscapular muscles are altered, there are anomalies in the scapular orientation which are called scapular dyskinesis.In previous works, we studied the feasibility of pseudo-kinematic studies of the scapula during arm elevation according to the thorax coordinate system derived from low-dose EOS® stereoradiographs. However, this method which was based on the location of specific scapular bony landmarks on each stereoradiographs, presented a low reproducibility and was difficult to use in clinical conditions.The aim of this Thesis was first to optimize this promising method In order to obtain a functional quantitative analysis of the scapula reliable and reproducible. Then, we would like to use this method in-vivo in order to assess the orientation of the scapula during arm elevation on pathologic subjects

Full textIn order to create a biomechanical model of the human body for injury prediction, in relation with road users protection, the laws of movements of skeletal parts under passive loading must be known as well as the resistive forces developed by the structure that limit movement amplitude. For the shoulder complex, very few 3D data on mobility are available and most of the work was done on volunteers with external markers. The objective of this work was to collect data on the relative movement of skeletal components of the shoulder complex, on resistive moment of the shoulder joints versus angular movements and to develop a kinematic model of the shoulder complex. A experimental device was develop to collect data with post mortem human subject. The protocol will be used to re-constitute co-ordinate systems and measurement points materialized by metallic implants inserted in the bones. The data analysis and numerical methods was used to estimate global and scapulo-humeral rotation center for voluntary and post mortem subjects. A measurement system for resistive moment of the shoulder joints was develop to estimate limit force. A kinematic model of the shoulder complex corresponds by two mechanism : a closed chain (sternum - clavicula - scapula - torso) with 2 degree of freedom and an open chain (torso - scapula - humerus) with 3 degree of freedom

Full textObjective : The general objective was to propose a reliable alternative to assess agonists-antagonists muscle balance in dynamic perspective by using a sector approach: the angular range method. Material and method : Three studies were conducted, each study involving joint particularly involved in human motion, and also in injury occurence related to the muscle balance between the main joint stabilizers. These are respectively scapulohumeral joint (internal ans external rotator muscles), femoro-tibial joint (flexor and extensor muscles), and lumbar spine (flexor and extensor muscles). Subjects were healthy volunteers, not specialists in a sport. The ratios by angular range of 10° were compared between the angular ranges and also compared to the classical ratios associated with the peak torques. Reliability was evaluated for all ratios. Results : All studies have shown that angular range ratios were signicantly different between angular ranges and also significantly different to the classical peak torque ratios. In addition, the results have highlighted a good absolute reliability of the ratios associated with the angular ranges of 10°. Conclusion : The sector method associated with angular ranges of 10° allows a reliable and relevant assessment of the muscle balance by a finer analysis of a major parameter of muscle function involved in physiopathology and motor performance

Full textThe aim of this work is to determine the possible links between strength and agonist/antagonist balance of the shoulder internal and external rotators muscle, and the glenohumeral stability. The first part of this work is a reminder of functional anatomy, joint physiology and biomechanics of the glenohumeral joint, and pathological aspects related to the problem of its stability and its exploration. The second part propose a critical analysis of technical exploration of muscular strength by isokinetic dynamometer to determine a reliable and reproducible protocol. We choose to use the more reliable and more suitable position for evaluation of pathological subject: the seated position with 45° of shoulder abduction in the scapular plane, with gravity corrected. The third part is aimed to research, from original clinical studies, the relationship between shoulder internal and external rotators muscle strength and balance, and shoulder instability on the one hand, and adaptations of this strength with sports practice on the other hand. Although a deficit in rotators muscle strength is associated with recurrent anterior instability, our work reporte no association between agonist/antagonist imbalance and recurrent anterior instability. In overhead sports and sports seeking the upper limbs, adaptations of strength, with a rotator strength increase on the dominant side, are inconsistent, and most importantly, our results reporte no agonist/antagonist imbalance induced by the sports practice. In conclusion, this work highlights adaptations in strength and balance of the shoulder internal and external rotators muscle associated with the glenohumeral joint instability, or induced by the sports practice. Tacking into account the limits of our experiment, we can hypothesis that any physiological adaptations induced by sport practice would not intervene as a pathophysiological mechanisms of desadaptation, or not be considered a risk factor predisposing, to glenohumeral joint diseases. Thus, our conclusion is that the agonist/antagonist balance would have a protective role of the joint stability; the occurrence of a muscle agonist / antagonist imbalance may be secondary to an anatomical lesion and mark the sign of its long and/or pejorative evolution

Full textThe aim of this thesis is to determine the effect of volleyball practice on shoulder muscles' adaptation. Rotator cuff muscles of the shoulder are assessed with a Kin Com® dynamometer in order to establish agonists / antagonists muscular strength ratios of volleyball players. Isokinetic tests have been completed using tests of performance. Results indicate: a better position of assessment in the scapular plane, differences of peaks torque of IR conc and ER ecc between professional players and young high level volleyball players, differences of functional IR conc / ER ecc ratio between the full range of motion and the end of the range of motion according to the level of practice, an evolution of the IR conc / ER ecc ratio of confirmed volleyball players during the sport season and a stabilization of the IR conc / ER ecc ratio of young high level volleyball players. The results confirm the effects of the practice of volleyball on the rotator cuff muscles of a player according to his level of practice, his age and during the sport season

Full textThe aim of this thesis was to contribute to the improvement of metrological properties of the scapulo-humeral movement collected by skin markers in an optoelectronic system. The first chapter deals with shoulder movement assessment, Techniques based on the markers placed on the anatomical landmarks of the scapula and acromial method provide an error of 5 to 6°. We have developed an original method based on an acromial approach and a double calibration which allow decreasing the error to 3-4. 5°. The second chapter evaluates the accuracy and repeatability of five functional methods for determining the glenohumeral rotation center. The error is between 11 mm and 17 mm according to the methods. The reproducibility study showed a strong influence of the range of motion and functional method. The third component of our work was to develop and evaluate a method for analyzing the scapulohumeral movement of the healthy and pathological child. The method was repeatable and accurate close to 5° but the exploration of the gleno-humeral joint during movement required the use of another Euler sequence than recommended in the literature (XZY). The final chapter of this thesis discusses the outcome and perspectives in particular, the interests of biomechanical models of the shoulder from custom imaging

Full textThe aim of this work was to improve the methods of kinematic assessment of the shoulder complex and of the cervical spine in order to improve understanding of scapular and cervical spine kinematics in asymptomatic and symptomatic subjects. The first part of this work provides a reminder of functional anatomy, a literature review of the 3D kinematics of the shoulder complex and issues relating to measurement techniques of both articular complexes. The second part is based on original clinical studies assessing: - the reliability of the measurement techniques of the rotations of both articular complexes and their enhancement by addition of scapular translations and the coupled mobility of the cervical spine and shoulder complexes. - the patterns of scapular kinematic in different ostéo-articular pathologies In conclusion, this work highlights: - intra-individual variability in the ability to reproduce a movement with the upper arm and in the accuracy of repositioning the head . -3D scapular translations (some with large ranges) associated with scapular rotations. - small movements of the cervical spine associated with upper limb movements relating to the proprioceptive role of the cervical. - spine specific scapular kinematic patterns depending on: - neurological lesions in the case of dynamic scapula alata, - the type of movement in common osteo articular pathologies

Full textI would like to make a practical thesis. Shoulder surgery is growing and growing as the population is ageing and people is doing more and more sports activities. A lot of technical progress were done but there are still a lot of surgical complications. On the other way some very old anatomical ideas are still alive. I want to see with the actual knowledge, if some surgical complications could be explained by anatomy. Subacromial pathology and bone quality remain the two mainproblems of shoulder surgery and pathology. That’s what had suggested to me this study about the shoulder. I was supposed to analyze glenoid bone first .The aim was to know more about arterial supply of glenoid. That was my firststudy (article 1). Then, I was interested in glenoid bone quality. And the second study had appeared. (article 2). During the shoulder dissection, I was looking for the fascia delto-trapezoidal which I didn’t found as described in books. It was my third study. (article 3). Going on I found the coraco-acromial ligament and I was surprised to see the constant portion under the acromial process. And that gave me the idea for the fourth study. (article 4).As I had discovered the very interesting technique of micro-Ct densitometry, I would like to apply it to the humeral head bone. There was the fifth study. (article 5)But, I want to know more and more about bone quality and I went on with the greater tuberosity and especially the area ofsupraspinatus insertion. The insertion and the sub-chondral bone were analyzed. There’s the last but not least study!(article 6). I was really interested in supraspinatus muscle and tendon and I want to follow the course of the muscle as the zone of conflict. I was the subject of study in life as I went through RMI . The muscle was reconstructed as finite element. Then it was possible to describe the zone of conflict with the supraspinatus. Here’s the seventh article. (article 7)

Full textThe aim of this study was to give a new definition to shoulder hyperlaxity. This work was conduced with clinical, surgical andmotion capture experimentations. We first gave a definition of hyperlaxity, as described actually in the literature, and its link with shoulder instability and treatment. Chapter 1 described also motion capture technics used along this work. Then, several studies were proposed. Study n°2 was a surgical one, and tempted to correlate peroperative capsular laxity and hyperlaxity. Therafter, study n°3 looked for an optimized way to examine external rotation of the shoulder. Studies N° 4 and 5 used motion capture analysis to assess clinical shoulder examination patterns and global reachable shoulder space volume. This volume was finally correlated to shoulder sign of hyperlaxity in study n°6. The last chapter, « general conclusions and perspectives » gather together conclusions of each study and redefine hyperlaxity. Finally, we report our prospect, giving first results of an anatomical study exploring the volumetric definition of shoulder range of motion described previously

Full textThe precise and quantified characterization of human movement is essential in many fields, particularly in clinic and sports, to enhance, preserve, or restore motor abilities. The complex anatomy of the shoulder gives it fine and large-range motion capability, at the cost of fragile stability, exposing it to significant risks of impairments that can compromise its mobility. To accurately estimate the kinematics of the shoulder complex, it is necessary to have a motion capture system that is fast, accurate, and suitable for routine use. Among the many tools employed, shoulder kinematic estimation via direct measurement is generally invasive or radiation-based, and in any case not suited for systematic evaluation. Indirect skin-based shoulder kinematic estimation methods, especially those using markers, are widely used but offer lower accuracy due to soft tissue artifacts. Numerous experimental and numerical strategies have been developed to improve their performance, though they have not yet fully satisfied expectations. Recently, markerless motion capture methods have emerged, but to date, none of them provide estimates compatible with the detailed kinematic modeling of the shoulder complex. The objective of this thesis was therefore to contribute to the development of shoulder kinematic analysis tools using both marker-based and markerless motion capture. A first sub-objective of this thesis was to study the influence of kinematic model optimization and scapular marker weight on scapular kinematics in a multibody kinematic optimization. The results of this first study highlighted that marker redundancy, meaning the use of more than three markers on the scapula, is recommended for scapular kinematic estimation in multibody kinematic optimization. These results also showed that the optimal marker weights are both participant- and movement-specific, but that an average weight set per movement could improve scapular kinematic estimation. The second sub-objective of this thesis was to develop a markerless motion capture method using a deep learning algorithm that allows for the kinematic tracking of the upper-limb, including the shoulder complex. This second study involved developing a 2D pose estimation algorithm capable of identifying 20 anatomical landmarks across five different movements with a median accuracy of less than 9 px. The markerless motion capture method developed based on this algorithm provided 3D estimates of the anatomical landmarks of the shoulder with an average accuracy of less than 15 mm, resulting in an articular kinematic accuracy of 14° for the scapulothoracic joint. These estimates were equivalent to, if not better than, those obtained using marker-based motion capture, with a significant time-saving due to the absence of preparation required. Further research is needed to transform this proof of concept into a fully functional motion capture tool and validate its potential to become the most suitable method for routine shoulder complex kinematic estimation

Full textThis work aimed at exploring the training modalities to develop maximal post impact ball velocity fo the tennis forehand drive, while assessing the potential risk of upper limb oeruse. The results of our studies showed that maximal power developed during a two-handed side medecine-ball(MB) throw explained 25% of the variation of maximal forehand ball velocitiy, and was achieved when using a MB mass of 5,7 % of player's body weight. However, the relationship between throwing distances and maximal ball velocity of forehand drive was weak. By contrast, a significant relationship was found between the performance for the one-handed side MB throw and the maximal velocity of the forehand drive. A six-week trainig program based on one-hand MB throws increased the ball velocity by 11%, but the shot accuracy tended to be reduced. In the same way, a six-week training program including forehand drives with an overweighted racketr about 12 % allowed the maximal forehand ball velocity to be improved (5%), without alteration in theshot accuracy. Finally, the comparison of muscular coordination between both MB throws and the forehand drive demonstrated that the trunk and upper limb muscles presented similar activity pattern and levels. The potentials for injury risk would thus not justify. In conclusion, the finding of this work contributed to the periodization of the strength and conditioning training in order to improve the forehand drive performance in nonprofessional competitive tennis players

Full textObstetrician Brachial Plexus Palsy (OBPP) is a common birth injury in children leading to shoulder joint deformity and abnormal function. While the management of OBPP disorder focuses on restoring the shoulder joint function, the underlying pathomechanics is not clearly understood yet. Computational models are effective to provide such insights, however, there is no pediatric shoulder joint model to understand the OBPP disorder. Thus, the global aim of this research work was to build a computational framework combining the advances in statistical shape modeling (SSM) and multi-body musculoskeletal modeling (MSKM) domains. Due to a lack of sufficient data in the pediatric cohort, I first developed the framework for adult shoulder joint. For this, I illustrated the accuracy of SSM in predicting 1) missing part of the scapula, and 2) muscle insertion regions on scapula and humerus bones. This method was then integrated with adult shoulder MSKMs to show the differences between generic and subject specific constructs. For the second aim of this thesis, I developed a pediatric MSKM of the shoulder joint complex using OpenSim software. Pediatric MSKM represented scapulothoracic, sternoclavicular, acromioclavicular, and glenohumeral joints with 13 degrees of freedom, and actuated by 52 musculotendon actuators representing 14 shoulder muscles. Using inverse kinematics and inverse dynamics approaches, the model was used to determine the differences in joint kinematics, and joint dynamics between healthy and unhealthy side of a single OBPP subject. Future work is focused on completing the framework on pediatric population and understanding the pathomechanics of OBPP
