The scapula plays an important role in normal shoulder function. In sports in which demands on the shoulder are extremely high, the quality of movements depends on the interaction between scapular and glenohumeral kinematics. Comparatively to a normal status, the scapular dyskinesis is defined as observable alteration in the position of the scapula and in the patterns of scapular motion in relation to the thoracic cage [1]. Surprisingly, only sparse literature focused on the isokinetic assessment of scapulothoracic muscles. To our knowledge, only Cools et al. [2,3] have investigated such evaluation, using a closed kinetic chain system. The aim of this study was to provide new insights in the isokinetic assessment of the scapular muscle performances, among sedentary and overhead athletes populations. 10 sedentary men (23.5  2.6 years; 67.3  62 kg) and 10 overhead athletes (22.2 +/- 2.3 years; 72.9 +/- 9.7 kg) participated into the study. All subjects were free of previous shoulder pathology. The overhead population included 2 volleyball, 2 handball, 3 tennis and 3 badminton players, all with at least 9 years of intensive practice. They sustained a bilateral isokinetic assessment (Biodex 3 dynamometer) of the protractors (PRO) and retractors (RET) of the scapula (closed kinetic chain). Subjects were seated and the closed kinetic chain attachment was placed in a horizontal plane, at 30° from the frontal plane, which corresponded to the scapular plane; the elbow was placed in full extension. The range of motion was individualized from the maximal protraction to the maximal retraction positions. After a specific warm up using an elastic theraband and familiarization on the isokinetic device, the isokinetic protocol consisted in 3 repetitions at slow speed (12.2 cm/s) and 5 repetitions at high speed (36.6 cm/s). The strength performances (peak-force in N) and ratios (Protractors / Retractors; PRO/RET) are described in Tables 1 and 2. The maximum force developed by scapular muscles decreased with increase in motion velocity. Generally, there was no dominance effect, except for the RET at high speed within the sedentary population (Table 1). The PRO/RET ratios remained inferior to 1 indicating higher performances on RET muscle group (Table 2). Even if the athletes recruited in our study used their shoulder in an asymmetrical way, we did not find any significant difference between the dominant and non dominant ratios in that population; only the PRO/RET ratio of sedentaries at high speed showed a dominance effect. The PRO/RET ratios were higher into the athletes, yet the difference did not reach statistical significance. There was no significant difference between both populations, if considering the absolute strength or the bodyweight normalized peak force. The sports population appeared more homogenous with lower standard deviation values for all data. Nevertheless, in such closed kinetic chain assessment, compensations of the trunk during protraction and of the elbow during retraction must be strictly controlled. The shoulder assessment in a closed kinetic chain allowed to investigate the force developed by the protractors and the retractors of the scapula. In spite of upper limb asymmetrical use through overhead activities, a dominance effect in strength performances or agonist-antagonist ratios was not detected among athletes recruited in that study. These preliminary results could be useful for further comparison with pathological cases. REFERENCES 1. W.

Complementary to the muscle strength measurement, the isokinetic dynamometry offers the opportunity to investigate another essential variable: the fatigue which can be defined as a deterioration in maximum torque generating capacity. Many articles in the literature refer to isokinetic fatigue protocols, yet we may consider that there is a lack of consensus about testing modalities and methodological aspects. The overall aim of that preliminary study was to investigate concentric fatigue protocols in terms of contraction number, measurement reproducibility and appropriateness of parameters classically analysed. Twelve male subjects (23  2 years old; 71  3 kg) without history of lower limb injury were included in the study. After standardized warm-up and familiarization with the isokinetic exercise (Biodex 3 dynamometer), each subject performed a unilateral concentric testing on their dominant side knee flexors and extensors. The protocol consisted in 50 maximal contractions at 180°/s angular velocity along a constant 100° range of motion. The fatigue protocol was repeated at 3 different sessions, separated by one week, in the same standardized conditions. Measured and calculated parameters were analysed: maximal work (Wmax); total work (Wtot); cumulated work on 10-20-30-40-50 repetitions (W10-20-30-40-50); different fatigue indexes: mean on the 3 last reps/Wmax (W3L/Wmax), mean on the 5 last reps/Wmax (W5L/Wmax), W3L/mean on the 3 first reps (W3L/W3F), W5L / mean on the 5 first reps (W5L/W5F). These fatigue indexes were established from the 50 repetitions protocol but also calculated on the 30 and 40 first repetitions of the whole test. The heart rate (HR) throughout the fatigue protocol was recorded using a Polar cardiofrequencemeter. A generalized linear mixed model (GLMM) was used for the statistical analysis of reproducibility. The cumulated work calculated on 20, 30, 40 or 50 repetitions was found to be reproducible for the Q muscle group. The same parameters calculated on the Fl muscle group showed a less satisfactory reproducibility. Among indexes of fatigue, the most reproducible were those using Wmax as denominator (by contrast with W3F or W5F as denominator), in particular the W5L/Wmax index for the Q. From 20 repetitions to the end of exercise, the fatigue indexes calculated on the Fl were significantly (p < 0.05) inferior to the indexes established for the Q, suggesting a more marked effect of fatigue on the Fl decrease of maximal strength production. With respect to the HR expressed in percentage of the theoretical maximal HR, the value averaged 53 % before exercise, 83 % after 20 reps and peaked at 87 % after 50 reps. After 2 minutes of recovery, the HR reached 58 % of the HR max. These findings must be taken into account when designing a fatigue isokinetic protocol, in terms of exercise duration and parameters to be analysed. [less ▲]

Sports activity involving the upper limb implies some powerful movements leading to the development of specific adaptations of the shoulder. These adaptive patterns increase the risk of injury. Shoulder rehabilitation in athletes should be guided by the results of a specific physical examination of the shoulder. In this article we propose an original evaluative form specifically designed for the athletic shoulder which takes into consideration the morphostatic and physical features as well as the possible bilateral asymmetries. The functional evaluation includes measurement of range of motion, flexibility, isometric muscle strength, position and motion patterns of the scapula. Progress achieved during rehabilitation programs can be monitored with successive evaluations which are helpful for determining the most suitable treatment. [less ▲]

Les épreuves isocinétiques destinées à apprécier la qualité de force musculaire ont fait l’objet de nombreux travaux de validation. Ces épreuves maximales, de courte durée (nombre réduit de répétitions), reconnaissent des applications dans des domaines variés : traumatologie et chirurgie de l’appareil locomoteur, affections neurologiques, insuffisances pulmonaire et cardiaque, prévention lésionnelle … Selon les contextes, les protocoles comportent des exercices concentriques et/ou excentriques à différentes vitesses angulaires. D’autres qualités musculaires, fondées sur des filières énergétiques différentes, peuvent bénéficier de l’exploration isocinétique. Ainsi, l’étude de la résistance à la fatigue, correspondant davantage au métabolisme anaérobie lactique, devrait représenter une application de choix. Cependant, les épreuves isocinétiques de résistance à la fatigue n’ont, à ce jour, pas bénéficié de la même attention méthodologique, rendant leur application clinique plus confidentielle. Il semble légitime de s’interroger sur les critères actuels d’interprétation d’un test de résistance à la fatigue, et en particulier sur la définition d’un résultat « anormal » impliquant une prise en charge thérapeutique. Plusieurs points retiennent notre attention : o groupes musculaires à explorer ; o choix du mode de contraction et de la vitesse angulaire ; o durée optimale de l’épreuve (nombre de répétions) ; o reproductibilité et caractère discriminant des paramètres mesurés et calculés ; o conséquences physiologiques de ce type d’effort et risques potentiels ; o champs d’application. Des résultats récents [1] indiquent, chez des sujets masculins sains pour les muscles quadriceps (Q) et fléchisseurs (Fl) du genou : - la bonne reproductibilité du paramètre Travail total (Wtot) mesuré sur le quadriceps au cours d’une épreuve à 180°/s, comportant 20, 30, 40 ou 50 répétitions ; le Wtot mesuré sur les Fl apparaît moins reproductible ; - les index de fatigue classiquement calculés par les dynamomètres isocinétiques mettent en relation les performances au terme de l’épreuve (3-5 dernières répétitions) avec la performance au début de l’exercice (3-5 premières répétitions). Sur base de la qualité de reproductibilité, de tels index de fatigue devraient laisser place à des index de fatigue rapportant la performance à la fin de l’exercice (3-5 dernières répétitions) au Wtot développé durant l’épreuve ; - les muscles ischio-jambiers se caractérisent par une résistance à la fatigue réduite en comparaison avec le quadriceps. Il est tentant d’ajouter cette particularité à la liste des facteurs intrinsèques de risque lésionnel des ischio-jambiers ; - les épreuves isocinétiques de résistance à la fatigue s’accompagnent d’une sollicitation cardio-vasculaire majeure : ainsi la fréquence cardiaque (FC) s’élève à 83 % de la FC maximale théorique dès la 20ème répétition, et atteint 87 % à la 50ème répétition. Une telle réponse indique clairement le risque potentiel des épreuves de résistance à la fatigue. Ainsi la durée (20 – 30 – 40 ou 50 répétitions) de l’épreuve sera adaptée à la population bénéficiant de l’évaluation. Références [1] Croisier et al.
