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 ▲]

Tendinopathy is characterized by pain in the tendon and impaired performance sometimes associated with swelling of the tendon. Its diagnosis is usually clinical but ultrasonography and magnetic resonance imaging can refine the diagnosis. Tendinopathy is highly prevalent and is one of the most frequently self reported musculoskeletal diseases in physical workers and sports people. Nevertheless, it is very difficult to carry out general epidemiologic studies on tendinopathy because of the varying sports cultures and sports habits in different countries. The aetiology of tendinopathy seems to be multi-factorial, involving intrinsic and extrinsic factors. The role of inflammation is still debated but the absence of inflammatory cells does not mean that inflammatory mediators are not implicated. Different theories have been advanced to explain pain and chronicity mechanisms, but these mechanisms remain largely unknown. “Conventional” treatments are generally employed empirically to fight pain and inflammation but they do not modify the histological structure of the tendon. However, these treatments are not completely satisfactory and the recurrence of symptoms is common. Currently, eccentric training remains the treatment of choice for tendinopathy, even though some studies are contradictory. Moreover, many interesting new treatments are now being developed to treat tendinopathy, but there is little evidence to support their use in clinical practice. [less ▲]

L’épaule du sportif exige une balance équilibrée entre mobilité et stabilité articulaire, autorisant performance et risque limité de survenue lésionnelle. Cependant, la pratique sportive intensive s’accompagne de diverses adaptations, parfois préjudiciables, que le clinicien devra évaluer et compenser. (1) Des adaptations spécifiques de la mobilité de l’articulation gléno-humérale côté dominant sont fréquemment rapportées chez les « overhead athletes ». Ces modifications se traduisent le plus souvent une rotation externe accrue, associée à une rotation interne réduite. Ce profil pourrait compromettre la stabilité articulaire. Des transformations osseuses et/ou des tissus mous, liées à la gestuelle du lancer, seraient à l’origine du profil de mobilité spécifique. La raideur postérieure, associée à l’hypermobilité en rotation externe, entraînerait des manifestations pathologiques secondaires chez l’athlète, tels que le conflit secondaire, les lésions du bourrelet supérieur (slap lesion) et le conflit interne intra-articulaire. Il semble opportun, sur le plan clinique, de contrôler le pattern de mobilité. Des mesures précises de la raideur de la coiffe postérieure et de la rotation externe, le bras positionné à 90° d’abduction dans le plan frontal, permettent d’objectiver les modifications. Des exercices d’étirement des structures postérieures peuvent être facilement exécutés par le sportif éduqué, après ses entraînements. Le travail de la coiffe des rotateurs internes dans le mode excentrique, sous forme d’exercices de pliométrie par exemple, favorise le contrôle du bras dans les positions extrêmes de l’armer. (2) La modification du pattern de mobilité de la scapula et la position asymétrique des scapulae sur le gril costal en condition de repos portent le nom de dyskinésie scapulaire. La dyskinésie scapulaire apparaît fréquente chez le sportif utilisant les membres supérieurs intensivement. Elle accompagne fréquemment la pathologie d’épaule sans en être une réponse spécifique. Les experts décrivent actuellement plusieurs types de dyskinésie scapulaire, correspondant à des perturbations de coordination et à une fatigabilité accrue des stabilisateurs de la scapula. Ces dyskinésies s’accompagnent souvent d’une raideur du petit pectoral et des structures postérieures (coiffe, capsule). L’observation du sportif au repos ou lors des mouvements du bras, des tests cliniques spécifiques adaptés aux troubles scapulaires et parfois des mesures de force maximale en chaîne fermée ou d’activité myoélectrique des muscles adjacents contribuent à objectiver ces dysfonctions scapulaires. Un traitement ciblé sur le renforcement des muscles essentiels à la stabilité et à la mobilité de la scapula lors des mouvements du bras permettra de restaurer la coordination et l’équilibre de ces groupes musculaires fixateurs. Des étirements spécifiques des structures capsulaires et musculaires postérieures ainsi que du petit pectoral rendront à la scapula sa mobilité et limiteront certaines positions vicieuses (antéprojection de l’épaule) accompagnant la dyskinésie. (3) Le centrage huméral exige une balance équilibrée entre les muscles agonistes et antagonistes, plus précisément entre les muscles rotateurs internes (RI), frénateurs du bras lors de l’armer et effecteurs du lancer, et les rotateurs externes (RE), responsables de la rotation externe lors de l’armer et du contrôle du bras en fin de lancer. L’alternance de contractions concentriques et excentriques rapides, et le respect de l’équilibre des forces agonistes/antagonistes (RE/RI) assurent la performance lors du geste sportif et réduit le risque de survenue lésionnelle. Des perturbations de cet équilibre sont régulièrement décrites lors de l’évaluation isocinétique, réalisée selon un protocole spécifique à l’épaule sportive (position, modes de contraction, vitesses angulaires). Ces déséquilibres apparaissent liés à certaines lésions tendineuses de la coiffe des rotateurs, ce qui justifie leur dépistage par des tests en début de saison. Une prise en charge de qualité, sur les plans préventif et curatif, devra comporter un renforcement adéquat et un suivi longitudinal du profil musculaire de l’athlète.

The understanding and tracking of human motion has been a subject of interest in the scientific community for more than one century. The long history of human motion analysis comes from the large scope of applications of such measurement that can be found in medicine, biomechanics, sport, ergonomics, and even civil engineering. More recently, those technologies have also been widely exploited for the development of animation movies and games. Needless to say, the techniques used one century ago significantly differ from those used today. This paper describes in a first part the evolution of the technological capabilities for motion analysis and the actual limitations. From this analysis and in a second part, we describe the experience related to the creation of a motion analysis laboratory at the University of Liège and show how such a platform could be the center of a multidisciplinary research and provide valuable information to various communities.

Introduction: It is well known that eccentric training is a successful way of treating chronic tendinopathy. Although clinical results are very positive, beneficial morphological and histological effects have not yet been elucidated. The aim of our experiment was to determine if there exist any intrinsic modifications in a tendon trained in concentric or eccentric modes, in a rat model, using an original method of measurement (cryo-jaws). Methods: 18 rats were divided into 3 groups: 6 for the control group, without physical restraint; 12 for a training of1 hour, 3 times a week, for 5 weeks, at a speed of 17m/min (1km/h), on a inclined treadmill: 6 rats running uphill at +15° for the concentric effort (group C) and 6 rats running downhill at -15° for the eccentric effort (group E). After this training period, the Achilles, patellar and tricipital tendons of both limbs were surgically removed in all 18 rats. Tendons taken from five rats of each group were subjected to a tensile test up to rupture using a “cryo” jaw. Tendons of the remaining rat of each group were subjected to a histological study. Results: The results showed significant changes in group E only: (1) an increase of the force required to rupture the patellar and tricipital tendons; (2) an improvement of the ratio between the force necessary to rupture the tricipital tendon and the body mass of the rats; (3) an increase of the surface area of the section of the tricipital tendon. No significant change was observed as far as constraint was concerned between groups. Histologically, we saw, in the group E, more peripheral blood vessels and a greater proportion of collagen. Conclusion: This study showed that the mechanical properties of tendon tissue are enhanced by eccentric training. Tendons become stronger, the amount of collagen increases and there is probably more interaction between collagen fibers (mechanotransduction). [less ▲]

Background ⁄ Aims: Latissimus dorsi (LD) transfer in the case of breast reconstruction remains frequently used because this muscle provides a good size source of tissue in reconstructive surgery. Given that, the consequences of the LD removal on shoulder function and the actual loss of maximal strength developed must be investigated. Methods: Twenty women (50 ± 7Æ5 years old) were evaluated before surgery, 3 and 6 months after an unilateral transfer of a pedicle flap of LD muscle used for breast reconstruction. Women performed a bilateral shoulder isokinetic assessment [for the internal rotators (IRs) and external rotators and for the abductor and adductor (ADD) muscles] allowing the establishment of bilateral muscular deficit status and the study of agonist ⁄ antagonist muscle ratios. The algofunctional and clinical status of the shoulders was analysed by the means of Constant score and specific shoulder clinical tests. The women did not perform any specific strengthening of muscle shoulder after surgery. Results: The isokinetic assessment showed a muscle weakness 3 and 6 months after LD transfer, mainly on the ADDs (33 ± 9% at 6 months) and on the IRs (16 ± 11% at 6 months). The Constant score significantly decreased after surgery on the operated shoulder. Women with a Constant score impairment showed pain during specific shoulder clinical tests. We also found a correlation between Constant score impairment and internal rotators weakness or rotator muscle imbalance. Conclusion: Given those results, we could advocate a specific shoulder strengthening after LD transfer, focused mainly on the IRs and ADDs. [less ▲]
