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.

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 two or three successive infiltrations. The aim of this study was to evaluate whether two infiltrations of PRP proves more effective than a single treatment. DESIGN: Prospective, randomized and comparative study of level 2. METHODS: Twenty patients suffering from chronic proximal patellar tendinopathy were enrolled into the study and split into two randomized groups (one or two 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. CONCLUSIONS: The comparison between one or two infiltrations of PRP did not reveal any difference between the two groups at short to mid term. A second closely-timed infiltration of PRP to treat proximal patellar tendinopathies is not necessary to improve the efficacy of this treatment in the short term. [less ▲]

The strength of respiratory muscles is crucial for quality of life, especially for patients with lung or neurological disorders. Several methods can be used to assess them: i.e direct or indirect, voluntary or involuntary. The conventional spirometry method assesses indirectly the respiratory function by measuring maximum inspiratory and expiratory pressure, which reflects the coordination of all respiratory muscles. Techniques of magnetic and electrical stimulation can detect a specific muscle dysfunction, independently of the patient's motivation, however they are invasive methods as measurements are made in the esophagus and stomach. The voluntary techniques are generally non-invasive and require patient's cooperation. Measures of respiratory muscle strength, coupled to a conventional spirometry, can predict the development of ventilatory support in patients at risk, and may be useful during weaning from mechanical ventilation in intensive care units.

Objectives: The restorative properties of platelets, through the local release of growth factors, are used in various medical areas. This article reviews fundamental and clinical research relating to platelet-rich plasma applied to tendinous lesions. Materials and method: Articles in French and English, published between 1 January 2012 and 31 December 2014 dealing with PRP and tendons were searched for using the Medline and Scopus data bases. Results: Forty-seven articles were identified which addressed pre-clinical and clinical studies: 27 relating to in vitro and in vivo animal studies and 20 relating to human studies. Of these, five addressed lateral epicondylitis, two addressed rotator cuff tendinopathies, ten dealt with patellar tendinopathies and three looked at Achilles tendinopathies. Conclusions: The majority of pre-clinical studies show that PRP stimulates the tendon's healing process. However, clinical series remain more controversial and level 1, controlled, randomised studies are still needed. [less ▲]

Background: platelet-rich plasma (PRP) infiltration represents a recent therapy for chronic tendinopathies. However, in the literature, this treatment remains controversial. Purpose: we suggest some ideas for improving this treatment. Methods: these suggestions were based on a review of published studies and our clinical experience. Conclusion: optimizing the technique for PRP collection is paramount. Different risk factors must be corrected before infiltration and chronic tendinopathies must be carefully selected. Finally, post-infiltration rehabilitation remains absolutely critical. Standardization of the use of PRP remains necessary in order to optimize the results. [less ▲]

Le cancer constitue une maladie fréquente en Belgique puisqu'un homme sur trois et une femme sur quatre sont confrontés à la maladie avant l'âge de septante-cinq ans (Fondation Registre du Cancer, 2008). La détection précoce et l'amélioration des traitements du cancer, généralement une combinaison de chirurgie, radiothérapie, chimiothérapie, hormonothérapie et thérapie ciblée, ont permis une augmentation du taux de survie. Cependant, ces traitements peuvent être à l'origine de nombreux effets secondaires, non seulement précoces, mais également tardifs, réduisant la qualité de vie. De nombreux programmes de réhabilitation après cancer sont basés sur la psychothérapie et le support social uniquement, or ceux-ci n'agissent généralement pas sur les problèmes physiques encourus par les patients tels que la fatigue, la prise de poids et la diminution des capacités fonctionnelles. C'est pourquoi nous émettons l'hypothèse qu'une revalidation physique, associée à des séances psycho-éducatives et constituant ainsi une prise en charge multidisciplinaire, permettrait d'améliorer d'autant plus la qualité de vie et le bien-être tant physique que psychologique des patients ayant été traités pour un cancer.

BACKGROUND: Very few studies have quantified the degree of fatigue characterized by the decline in the maximal voluntary contraction (MVC) force of the trunk extensors induced by the widely used Sørensen test. OBJECTIVE: Measure the degree of fatigue of the trunk extensor muscles induced by the Sørensen test. METHODS: Eighty young healthy subjects were randomly divided into a control group (CG) and an experimental group (EG), each including 50% of the two genders. The EG performed an isometric MVC of the trunk extensors (pre-fatigue test) followed by the Sørensen test, the latter being immediately followed by another MVC (post-fatigue test). The CG performed only the preand post-fatigue tests without any exertion in between. RESULTS: The comparison of the pre- and post-fatigue tests revealed a significant (P <0.05) decrease in MVC force normalized by body mass (−13%) in the EG, whereas a small increase occurred in the CG (+2.7%, P = 0.001). CONCLUSIONS: This study shows that the Sørensen test performed until failure in a young healthy population results in a reduced ability of the trunk extensor muscles to generate maximal force, and indicates that this test is valid for the assessment of fatigue in trunk extensor muscles.

Introduction : Le cancer du sein ainsi que ses traitements sont à l'origine de nombreux effets secondaires indésirables. L'objectif de l'étude est de déterminer les bénéfices éventuels, tant sur le plan physique que psychologique, d’un programme de revalidation multidisciplinaire chez des femmes ayant été traitées pour un cancer du sein. Méthodologie : 122 patientes ont été recrutées, 61 faisant partie du groupe contrôle et 61 du groupe traité. Celui-ci a bénéficié d’une revalidation de trois mois comprenant un entraînement physique supervisé et diverses sessions psycho-éducatives. Les évaluations, effectuées avant et après la prise en charge, ont inclus des mesures anthropométriques et de composition corporelle, une évaluation des capacités fonctionnelles et différents questionnaires. Résultats : Au terme des trois mois, l’état de santé (qualité de vie), le rôle fonctionnel, l’état émotionnel et les fonctions physiques, cognitives et sociales s’améliorent significativement au sein du groupe traité. Cette observation s’applique également aux symptômes de fatigue, d'insomnie, de douleur, de dyspnée, de perte d'appétit, d’anxiété et de dépression ainsi qu'aux paramètres physiques obtenus par l'intermédiaire des évaluations fonctionnelles. Au sein du groupe contrôle, ces améliorations n’apparaissent pas et une augmentation significative de l'indice de masse corporelle et du pourcentage de graisse corporelle est observée. Conclusion : Cette étude préliminaire montre ainsi la faisabilité et les effets bénéfiques d’une prise en charge multidisciplinaire chez des femmes au terme de leurs traitements pour le cancer du sein.

Certaines tendinopathies présentent une évolution désespérément chronique malgré l’instauration d’un traitement conservateur bien conduit. Diverses études soulignent les propriétés réparatrices des plaquettes qui pourraient accélérer la cicatrisation de différents tissus. Le plasma riche en plaquettes (platelet-rich plasma ou PRP) représenterait une thérapeutique d’avenir. Les plaquettes libéraient, lors de leur dégranulation, divers facteurs de croissance. Ceux-ci favoriseraient la cicatrisation tendineuse. Actuellement, les effets du PRP restent toujours discutés voire controversés : les résultats cliniques sont parfois contradictoires même si son efficacité in vitro et sur animal apparait plus franche. Cette variabilité pourrait s’expliquer par l’absence de consensus relatif au mode de préparation du PRP, à la concentration plaquettaire, à la présence ou non de leucocytes, à la technique d’infiltration et au protocole post-infiltration.
