Les athlètes de lancer présentent une mobilité passive gléno-humérale de l’épaule dominante spécifique avec une majoration de la rotation externe et une limitation de la rotation interne. La limitation interne semble liée à une raideur capsulo-musculaire postérieure, favorisant les pathologies de l’épaule sportive. Matériel et méthodes Vingt hommes, sportifs d’armer / lancer (volley-ball, handball) et pratiquant au moins 6 heures d’entraînement depuis plus de 5 années ont participé à cette étude. Ils présentaient tous une raideur des structures postérieures évaluée en clinique. Lors de l’inclusion dans l’étude, 10 athlètes (22,5 ± 4 ans) étaient asymptomatiques, 10 (24,8 ± 4 ans) présentaient une épaule dominante symptomatique (≥ 3/10 sur l’EVA). Les athlètes ont étiré chaque jour leur épaule dominante (sleeper stretch et cross body arm) pendant 4 semaines (5 x 30’'). Avant et après le programme d’étirement des structures postérieures, ils ont subi un test isocinétique de force maximale des rotateurs internes et externes ainsi qu’une analyse tridimensionnelle définissant la cinématique scapulaire. Résultats Après 4 semaines d’étirement des structures postérieures, tous les athlètes ont montré un gain significatif de mobilité en rotation interne passive. Nous n’observons aucune modification de la cinétique scapulaire lors de l’analyse 3D après les étirements chez les athlètes asymptomatiques ; les athlètes symptomatiques présentent une diminution du tilt antérieur scapulaire au repos après les 4 semaines. L’évaluation isocinétique des rotateurs d’épaules après les étirements montrent uniquement une légère réduction (- 4% ; p < 0,05) de la force des rotateurs internes à 60°/s en concentrique chez les athlètes asymptomatiques. Les sportifs qui décrivaient des douleurs avant les étirements sont significativement améliorés après le programme de 4 semaines ; cette diminution de la douleur est corrélée au gain en rotation interne passive. Discussion L’étirement pendant 4 semaines des structures postérieures de l’épaule raide sportive permet une augmentation de la mobilité passive. Ce gain de mobilité est corrélé à la diminution de la douleur chez les athlètes symptomatiques. [less ▲]

The pathophysiological mechanisms of tendinopathies integrate various intrinsic and extrinsic factors. Classic «passive» therapeutics have a limited action. Because of a better pathophysiological understanding of tendinopathies, more recent treatments (injections of various compounds, infiltrations of platelet-rich plasma, stem cells) would lead to a longterm healing. In case of failure of conservative managements and depending on the anatomical site, a surgical approach may be considered. [less ▲]

Objective The aim of this controlled, randomized, and double-blind study was to determine whether Kinesiotape® placed on healthy hamstrings could influence the isokinetic performances of this muscle group and of its antagonist, the quadriceps. Methods Twelve healthy men, aged 18–30 years, were subjected to an isokinetic evaluation in 3 different conditions (without Kinesiotape®, placebo Kinesiotape® to hamstrings, facilitation Kinesiotape® to hamstrings) in randomized order. The 3 sessions assessed peak torque (N.m), work (J) and angle to peak torque (°) in concentric 60 and 240°/s for hamstrings and quadriceps, and in eccentric 30°/s for hamstrings. Results Isokinetic performances in the 3 different conditions were not significantly different (P>0.05) in particular for the hamstrings concentric and eccentric peak torques. Only the angle to peak torque for hamstrings in eccentric 30°/s was modified when comparing placebo Kinesiotape® with no Kinesiotape® condition (P<0.05). Conclusion Kinesiotape® intervention in healthy subjects’ hamstrings did not influence neither the strength of this muscular group nor the performances of its antagonist, the quadriceps. [less ▲]

Introduction: The Victorian Institute of Sports Assessment–Patellar (VISA-P), originally developed for English-speaking patients, assesses the severity of patellar tendinopathy symptoms. Although this questionnaire has already been translated into different languages, it has never been adapted for French-speaking patients, which is surprising. Indeed, French is not only spoken by most than 275 millions of people all around the world. The aim of our study was to validate a French version and verify its psychometric properties. Materials and Methods: The translation and cultural adaptation were performed according to international recommendations in six steps: initial translation, translation merging, back translation to the original language, expert committee review to test the pre-final version, and expert committee appraisal. Once the final French version (VISA-PF) was obtained, certain psychometric properties were assessed in 92 subjects were included and divided into three groups: pathological subjects (n = 28), asymptomatic subjects (n = 22) and sports-risk subjects (n = 42). Results: The different members of the expert committee agreed with the final version. The average scores of the VISA-PF obtained were 53 (± 17) for the pathological group, 99 (± 2) for the healthy group and 86 (± 14) for the sports-risk group. The test-retest reliability of the VISA-PF was excellent with an intra-class correlation coefficient of 0.99 and good internal consistency (α = 0.9). Correlations between the VISA-PF and diverging measures of the SF-36 were low and the correlation coefficient values measured between the VISA-PF scores and converged items of the SF-36 were higher. Conclusion: The VISA-PF is understandable, reliable and suitable for French-speaking patients with patellar tendinopathy. [less ▲]

Introduction : The Victorian Institute of Sports Assessment– Achilles (VISA-A) was designed to evaluate the clinical severity of Achilles tendinopathy. It has been developed in English and therefore is not adapted for French-speaking patients. Although this questionnaire has already been translated into different languages but not in French. French is spoken by most than 275 millions of people and is one of the 2 official languages of the International Olympic Committee, and one of the 6 official languages and one of the 2 working languages of the United Nation Organisation. The aim of this study was to translate this questionnaires into French and to study its reliability and validity. Methods : The questionnaire was translated into French (VISA-AF) according to the "guidelines for the process of cross-cultural adaptation of self-report measures" using six steps: translation, synthesis, back translation, expert committee review, pretesting, and appraisal of the adaptation process by the expert committee. Once the final versions obtained, several psychometric proprieties such as test-retest fidelity, internal coherence, construct validity and floor and ceiling effects were evaluated. We recruited 116 subjects who were distributed in 3 groups: pathological patients (n=31), at risk athletes (n=63), healthy people (n=22). Results : The questionnaire was approved by the expert committee after the pre-final version test. On a scale ranging from 0 (theoretical minimum) to 100 (asymptomatic subject), the average scores of the VISA-PF obtained were 59 (± 18) for the pathological group, 99 (± 1) for the healthy group and 94 (± 7) for the sports-risk group. The VISA-A-F shows excellent reliability. The VISA-AF shows low correlations with the divergent sub-scales of the SF-36 and moderate correlations with the convergent sub-scales of the SF-36. No floor and ceiling effects were detected during the evaluation of the two questionnaires. Conclusion : The French versions of the VISA-A is equivalent to its original version and is reliable and valid questionnaire for French speaking patients with Achilles tendinopathy. [less ▲]

INTRODUCTION: Jumper's knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. METHODS: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10--point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA--P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub--maximal eccentric reeducation. RESULTS: Pain during daily activities significantly decreased with time. During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. CONCLUSION: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol can improve symptoms of chronic jumper's knee in patients non--responsive to classical conservative treatments.

Introduction: Some clinical series have evaluated the effect of platelet-rich plasma (PRP) in the treatment of proximal patellar tendinopathy. Although it is possible that a single infiltrative administration may prove to be an effective treatment for this indication, most of the existing studies evaluated the effects of 2 or 3 successive infiltrations. The aim of this study was to evaluate whether 2 infiltrations of PRP proves more effective than a single treatment. Material and methods: Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (1 or 2 infiltrations of PRP, respectively). The 3-month follow-up evaluation consisted of VAS, IKDC and VISA-P scores, along with algometer, isokinetic and ultrasounds evaluations. After 1 year, subjects were contacted to define their functional evolution. Results: The concentration of the PRP used for each infiltration was similar in both groups, and contained no red or white cells. Results revealed no difference in treatment efficacy between the groups. Discussion and conclusion: The comparison between 1 or 2 infiltrations of PRP did not reveal any difference between the 2 groups at short to mid term. A second closely-timed infiltration of PRP to treat chronic proximal patellar tendinopathy is not necessary to improve the efficacy of this treatment in the short term. [less ▲]
