Der volle Inhalt der QuelleThe 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

Der volle Inhalt der QuelleThis work takes place in the context of shoulder complex motion measurement in biomechanics. We present the technologies and methods that apply to this problem, and the associated obstacles (particularly the skin tissue deformation), in order to justify our choice of performing data fusion between measurements where the subjects remain still, and other where they are in motion. We suggest to perform this data fusion through spatial interpolation of reference frames from scattered data, specifically with the natural neighbors algorithm, that has been adapted to the framework of this study. A series of experimentations with a manipulator robot has been performed in order to assess the feasibility of the developed method, the robot giving access to ground truth that would be unavailable with human experimentations. The results we obtained encouraged us to pursue the study with human experimentations. These experimentation have been performed using an optoelectronic motion capture technology. The data gathered while subjects remained still, and the one acquired with the subjects in motion allowed us, through natural neighbor’s interpolation, to estimation the motion of the scapula relative to the thorax, for abduction, flexion, and scapular plane elevation movements. The results we obtained were similar to the ones found in the literature, encouraging on the one hand the method we developed, and on the other hand the spatial interpolation approach for bone motion measurement in biomechanics, compensating the skin tissue artefact

Der volle Inhalt der QuelleL’utilisation de données quantitatives afin de diminuer la prévalence des blessures musculosquelettiques liées au travail est souhaitée et le développement de systèmes portables permettant de mesurer l’amplitude articulaire (capteurs inertiels; IMU) et l’activité musculaire (électromyographie; EMG) pourrait permettre d’obtenir ce type de données. La revue systématique de la littérature sur la validité des capteurs inertiels effectuée dans le cadre de ce mémoire a permis d’identifier un manque d’évidence scientifique pour l’évaluation des mouvements complexes à l’épaule. L’objectif principal de ce mémoire est donc (1) d’évaluer la validité concourante d’IMU (Xsens) dans le calcul d’élévation du bras comparé à un système de capture de mouvements (Vicon) lors de mouvements simples et lors de tâches de manutention; et (2) d’établir la validité discriminante du système d’EMG (Trigno) pour évaluer l’activité musculaire. Méthodologie : Seize sujets ont participé à une séance d’évaluation demandant la réalisation de mouvements simples à l’épaule et de transport de charges (poids et hauteurs de transport variables). Le coefficient de corrélation et l’erreur de mesure (RMSE) ont été calculés afin de comparer les mesures d’amplitude articulaire obtenues à l’aide du Xsens et du Vicon et le root mean square (RMS) ainsi que le pic d’activité musculaire des deltoïdes (antérieurs et moyens) ont été calculés pour déterminer l’effet du poids et de la hauteur (ANOVA à mesures répétées). Résultats : Les coefficients de corrélation entre les amplitudes articulaires obtenues par le Xsens et le Vicon sont élevés (>0,84) et les RMSE sont bas (<11,5°). Un effet significatif du poids et de la hauteur, et un effet d’interaction poids x hauteur ont été observés pour le RMS du deltoïde antérieur (p<0,001) et moyen (p<0,03) et pour le pic d’activité du deltoïde antérieur (p<0,003). Conclusion : L’utilisation combinée du Xsens et du Trigno est un outil intéressant afin d’identifier le niveau de demande de l’emploi, puisqu’ils recueillent des données valides d’amplitude articulaire et d’activité musculaire.
Quantitative assessments of workplace settings are required to diminish the prevalence of work-related shoulder disorders. Recent development of wearable sensors to record muscle activity (electromyography [EMG]; Trigno, Delsys) as well as shoulder range of motion (inertial measurement unit; MVN, Xsens) could potentially be used for such workplace assessments. A systematic review on the validity and reliability of IMUs performed within this thesis identified a knowledge gap for shoulder joint movements during complex tasks. The primary objective of this thesis was therefore (1) to assess the concurrent validity of the Xsens system for assessment of shoulder range of motion compared to a motion capture system (Vicon) during simple movements and working tasks and (2) to establish the discriminative validity of the Trigno EMG system for the evaluation of muscle activity. Methodology: Sixteen subjects participated in one session in which they performed simple movements and work lifting tasks (different weights and lifting heights). The correlation coefficient (r) and the root mean square error (RMSE) were used to compare the data collected by the Xsens and the Vicon. The root mean square EMG envelope (RMS) and the peak EMG activity of anterior and middle deltoids were used to establish the effect of weight and height (repeated measure ANOVA). Results: The correlation coefficient between joint angles measured with the Xsens and the Vicon was high (>0.84) and the RMSE was low (<12.82°). A significant effect of weight, height and a weight x height interaction effect were observed for the RMS (anterior; p<0.001; middle: p<0.03) and the peak EMG activity (anterior; p<0.003). Conclusion: The combination of an inertial measurement unit system and a wireless EMG is a potentially useful tool to assess physical demand in real work context as it provides valid data on muscular activity and range of motion.

Der volle Inhalt der QuelleThe 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

Der volle Inhalt der QuelleThe first objective of this thesis was to characterize upper limb motor strategies in persons with shoulder impingement syndrome (SIS) during reaching movements. The second was, for the same population, to evaluate the effects of supervised and unsupervised movement training with feedback on motor strategies. Thirty-three subjects with SIS participated in two visits, one day apart. Motor strategies were characterized using upper limb kinematic patterns (total joint excursion and final position) and shoulder muscular activity while reaching toward targets located at 90° of arm elevation in two different planes. Upper limb motor strategies were evaluated before, during, immediately after and 24 hours after supervised movement training and immediately after unsupervised training. Movement training, performed during the first visit, consisted of reaching movements executed under the supervision of a physiotherapist who gave feedback to restore proper shoulder control; while unsupervised training, performed during the second visit, consisted of reaching movements executed in front of a mirror. Subjects with SIS had motor deficits during reaching movements with more involvement of the trunk and shoulder in rotation, a more anterior plane of shoulder elevation at the end of reaching and alteration in the trapezius muscular activity. During and following supervised movement training with feedback, total excursion of the trunk and final position of the trunk and shoulder were improved during and immediately after training, while 24 hours after training, the kinematics of these joints were back to baseline level. The addition of unsupervised training with visual feedback, performed 24 hours after the supervised training, helped return kinematics back to the level observed immediately after supervised training. In conclusion, supervised movement training with feedback brought temporary changes in the upper limb motor strategies and improved some aspects of the kinematics. One supervised training session was not enough to bring about permanent improvement in the kinematic patterns. However, unsupervised training helped to regain the improved kinematics and appears to be a good complement to supervised training. Therefore, our results support the use of movement training to rehabilitate the motor deficits associated with SIS.

Der volle Inhalt der QuelleSimultaneous apparition of depth and color sensors and super-realtime skeleton detection algorithms led to a surge of new research in Human Motion Capture. This feature is a key part of Human-Machine Interaction. But the applicative context of those new technologies is voluntary, fronto-parallel interaction with the sensor, which allowed the designers certain approximations and requires a specific sensor placement. In this thesis, we present a multi-sensor approach, designed to improve robustness and accuracy of a human's joints positionning, and based on a trajectory smoothing process by temporal integration, and filtering of the skeletons detected in each sensor. The approach has been tested on a new specially constituted database, with a specifically adapted calibration methodology. We also began extending the approach to context-based improvements, with object perception being proposed

Der volle Inhalt der QuelleHow optimal are human movements ? This thesis tackles this issue by focusing especially on climbing movements, studied here under three complementary aspects which are the experimental gathering of climbing sequences, the biomechanical analysis of these data, and the synthesis of gestures by timing optimization. Walking has been largely studied, with good results in animation [Mordatch 2013]. We are interested here especially in the original question of climbing motions, whose diversity and multicontact aspect present an interesting complexity for the evaluation of the human motion characteristics. The heterogeneity of climbing gestures can be linked to several factors which are the variety of wall shapes, the multiplicity of climber skill levels, and different climbing categories, namely bouldering, route climbing or speed climbing. Our exploratory approach of this sport consists in three steps: the data collection by multicamera marker-based motion capture, combined with a set of force sensors mounted on an in-laboratory bouldering wall; a gesture analysis by inverse dynamics, taking only kinematic data as inputs, based on the minimization of internal torques to resolve the multicontact ambiguity, intrinsic to the climbing activity, validated by comparison with sensor measurements; and finally, the use of the energy efficiency criterion for synthesizing the best timing associated with a given sequence of movements. Experimental recordings were made at McGill University which has a climbing wall instrumented of 6 force sensors, and a motion capture device of 24 cameras, which allowed us to collect data on a population of nine subjects. The analysis of these data is the second part of this thesis. The addressed challenge is to find the external forces and internal torques from the climber's movements only. To this end we assume an optimal distribution of internal torques. After analysis, the distribution turns out to be rather uniform than proportional to the muscle capacity associated to each body joint. Finally, in a third and last part, we focus on the timing of climbing gestures, taking as input the path of the climber, possibly after inverse kinematics in order to overcome the need for a capture with markers and infrared cameras. As output, an optimal timing for this path is found. This timing is realistic, but lacks of a modelization for hesitation and decision making instants, as well as a model for the contact establishment, with the associated temporal delay currently not taken into account
