De nouveaux outils de mesure permettent de quantifier la cinématique et la dynamique articulaire fonctionnelle des athlètes (systèmes optoélectroniques 3D, plateforme de forces, électromyographie, …). Ces données sont importantes dans le sens où elles donnent à l’équipe médicale et sportive des informations objectives sur le geste du sportif dans sa pratique réelle. Elles favorisent la compréhension et l’amélioration de la performance ainsi que la prévention lésionnelle et la détection de situations à risque. Dans le cadre d’un suivi longitudinal des sportifs, ces mesures sont intéressantes pour mettre en place des critères objectifs et spécifiques à l’athlète de retour sur le terrain après une blessure. Ce document a pour objectif de présenter les principaux outils disponibles dans les laboratoires de biomécanique et d’illustrer leurs utilisations à travers 2 exemples : l’influence de la raideur de l’épaule sur la mobilité de l’épaule et l’analyse cinématique du service au tennis.

Introduction: The treatment of choice for tendinopathies is eccentric reeducation. Although the clinical results appear favourable, the biomechanical changes to the tissue are not yet clear. Even if the mechanotransduction theory is commonly accepted, the physiology of tendons is not clearly understood. We aimed to better define the biomechanical and histological changes that affect healthy tendon after eccentric and concentric training. Materiel and Methods: This study compared the effects of 2 methods of training (eccentric (E) training and concentric (C) training) with untrained (U) rats. The animals were trained over a period of 5 weeks. The tricipital, patellar and Achilles tendons were removed, measured and a tensile test until failure was performed. A histological analysis (hematoxylin and eosin and Masson's trichrome stains) was also realized. Results: There was a significant increase in the rupture force of the patellar and tricipital tendons between the U and E groups. The tricipital tendons in the control group presented a significantly smaller cross-sectional area than the E- and C-trained groups, but none was constated between E and C groups. No significant difference was observed for the mechanical stress between the three groups for all three tendons. Histological studies demonstrated the development of a greater number of blood vessels and a larger quantity of collagen in the E group. Discussion and conclusion: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. Our results partly explained how mechanical loading, especially in eccentric mode, could improve the healing of tendon. [less ▲]

In sports, where regular and intensive training could progressively lead to traumatic situations, accurate measurement of kinematic parameters can help to predict and anticipate injuries. Overhead throwing athletes may develop an increased stiffness of the shoulder capsule. The resulting diminution of the gleno-humeral range of motion is usually associated with decreased performance and injury risks. This study illustrates the detection of these situations that put the athlete at risk. [less ▲]

This work is part of a project that deals with the three-dimensional (3D) analysis of normal and pathological gaits based on a newly developed system for clinical applications, using low-cost wireless accelerometers and a signal processing algorithm. This system automatically extracts relevant gait events such as the heel strikes (HS) and the toe-offs (TO), which characterize the stance and the swing phases of walking. The performances of the low-cost accelerometer hardware and related algorithm have been compared to those obtained by a kinematic 3D analysis system and a force plate, used as gold standard methods. The HS and TO times obtained from the gait data of 7 healthy volunteers (147 trials) have been found to be (mean ± standard deviation) 0.42±7.92 ms and 3.11±10.08 ms later than those determined by the force plate, respectively. The experimental results demonstrate that the new hardware and associated algorithm constitute an effective low-cost gait analysis system, which could thus be used for the assessment of mobility in routine clinical practice.

Tendinopathies are common and frequently resisting to actual conservative measures. The aim of this review was to gather the actual knowledge concerning the platelet-rich plasma (PRP) treatment in tendon lesion. The interest of this well-known technique, applied since almost 15 years in facial and dental surgery, is growing in the sports world because of its potential ability to treat refractory tendinopathies and to get back quickly a functional use. However, given the relative recent knowledge about PRP in sports medical, the studies could not yet reproduce the beneficial effects obtained in-vitro. Most studies about the subject indeed show an improvement in symptoms after PRP treatment but, because of the many biases introduced, such as the lack of population, the lack of control group or the many different kind of PRP used, the studies cannot be conferred a high level of evidence. Therefore, there is no evidence of formally advise the use of PRP in the treatment of tendinopathy. So the main research field in the close future will have to determine a standard for the manufacture of PRP and the protocols of the future studies in order to be able to compare them. [less ▲]

Les tendinopathies apparaissent fréquentes au sein de la population active et sportive. Actuellement, la rééducation excentrique constitue une thérapeutique de choix dans leur traitement. Stanish en proposa dès les années 80 les principales règles. Bien que les résultats apparaissent favorables en clinique, les adaptations morphologiques et biochimiques des tissus n’ont pas encore été élucidées. Nous avons démontré que l’effort excentrique (réalisé par des rats en course en descente) participait au développement macroscopique du réseau de vaisseaux sanguins au niveau de l’épitendon et à une amélioration de la résistance à la traction longitudinale tendineuse. Ceci confirme donc que les propriétés mécaniques du tendon de rat sont améliorées après un entraînement excentrique. Le tendon, plus résistant, augmenterait sa quantité de fibres de collagène et probablement les interactions entre elles. La mécanotransduction serait le processus responsable du remaniement tissulaire lors de l’application de contraintes mécaniques. Cependant, en pratique clinique, une vingtaine de séances d’entraînement minimum semblent néanmoins nécessaires pour assurer l’efficacité du traitement. Depuis quelques années, en traumatologie sportive, les propriétés réparatrices des plaquettes sanguines sont mises à profit pour stimuler la cicatrisation tendineuse. Nous avons démontré, selon a modèle animal, que celles-ci permettaient d'accélérer le processus cicatriciel tendineux mais en amélioraient également la qualité. Cependant, ce processus ne peut se dérouler correctement que si le tendon est soumis à des contraintes mécaniques afin d'orienter les neo-fibres de collagène selon les lignes de forces. Nous sommes donc convaincus qu'en pratique clinique, une prise en charge rééducative excentrique sous-maximale est indispensable dans les suites d'une injection de concentré plaquettaire pour traiter une tendinopathie chronique.

In human motion analysis, bone motions are usually expressed relatively to anatomical reference frames. The anatomical reference frames are constructed thanks to the localization of bony landmarks during a static phase prior to the acquisitions. These landmarks are identified by means of palpation. Accurate comparison between subjects and studies implies good reproducibility and repeatability of the palpation process. However, all investigators don’t have a long experience in palpation. In this paper, the reproducibility and repeatability of palpation for junior investigators were measured. Results show worse reproducibility and repeatability than what is usually expected. These errors have particularly an influence on the definition of the reference frames of the arm. This study therefore emphasizes on the need of a specific training of operators working in a motion lab. [less ▲]

The accuracy of the Codamotion system for 3D measurement depends mainly on the signal level of the sensors and the resolution of the system at the marker localization. When using several units to cover a large field of view, the estimated position of the different units might differ. We propose a method taking both resolution and signal level in to account, instead of only the signal level as in the built-in weighting process. This new method offers improved accuracy. [less ▲]
