Background: The contralateral shoulder is often used as a reference when evaluating a pathological shoulder. However literature provides contradictory results regarding the symmetry of the scapular pattern in a healthy population. We assume that several factors including the gender and the type of motion may influence the scapula bilateral symmetry. Method: The dominant and non dominant shoulders of two populations of men and women composed of 11 subjects each were evaluated for three distinct motions: flexion in the sagittal plane, abduction in the frontal plane and gleno-humeral internal/external rotation with the arm abducted at 90°. Posture, kinematic and range of motion were studied separately. Results: Asymmetries are observed for motions performed in the frontal and sagittal plane but not for the internal/external rotation with the arm abducted at 90°. Multiplane asymmetries are observed for the male population, whereas asymmetries for the female one are mainly uniplanar. For both men and women, the scapula has a larger upward rotation on the dominant side. For men, a larger posterior tilt is also observed. The asymmetries mainly originate in the scapula kinematic and not in its original posture. Discussion: Even if the asymmetries are not large in terms of amplitude (inferior to 5°), one should be aware of their existence and the influence of the composition of the studied population when using the contralateral shoulder as a reference.

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.

Introduction : Le plasma riche en plaquettes (PRP) aurait des effets bénéfiques sur les symptômes des tendinopathies grâce à la libération locale de leurs nombreux facteurs de croissance. Le but de cette étude est d’évaluer les résultats d’une injection de PRP sur la symptomatologie des patients présentant une tendinopathie patellaire supérieure. Matériels et Méthodes : Vingt patients atteints d’une tendinopathie patellaire supérieure, rebelle aux traitements conservateurs classiques depuis au moins 3 mois, ont bénéficié d’une évaluation du statut algo-fonctionnel (EVA, algomètre de pression, VISA-P et IKDC) et des performances physqiues (isocinétique et optojump), ainsi que d’un bilan d’imagerie (échographie et IRM). Ces analyses ont été réalisées en pré-injection ainsi qu’aux 6èmeet 12èmesemaines post-injection. Le test isocinétique évaluait la force des quadriceps et des ischios-jambiers des deux membres suivant différentes modalités (C60°/sec, C240°/sec et E30°/sec). Le test Optojump évaluait la détente et la puissance musculaire par la mesure de la hauteur de saut via deux modalités («Counter Movement Jump » et « Drop Jump »). Le PRP est obtenue à l’aide d’une machine d’aphérèse (COM.TEC, Fresenius-Kabi), permettant d’obtenir une concentration plaquettaire reproductible d’un patient à l’autre, en l’absence quasi totale de globules rouges et blancs. L’infiltration intratendineuse de PRP (6mL) est réalisé à la pointe de la rotule in loco dolenti sans anesthésie locale. Résultats : Les résultats de notre expérimentation démontrent qu’une seule injection locale de PRP accompagnée d’un programme de rééducation excentrique améliore significativement la cicatrisation du tendon patellaire au niveau du score EVA, de l’algomètre de pression, des scores VISA-P et IKDC. Lors du test isocinétique, seuls l’augmentation du MFM des ischios jambiers en C240°/sec, de la différence bilatérale des ischios jambiers en C60°/sec ainsi que de l’EVA en E30°/sec était significative. Les résultats optojump en terme de détente et puissance musculaire ne montrent pas d’amélioration des performances. Néanmoins, l’EVA du « Counter Movement Jump » se voit significativement diminuée après l’infiltration. Enfin, les résultats de l’imagerie (échographie et IRM) ne démontrent pas de modification significative du tendon. Conclusions : L’injection locale de PRP dans le cadre de tendinopathies patellaires supérieure permet une diminution de la symptomatologie douloureuse à 6 semaines, se poursuivant à 12 semaines. La performance fonctionnelle et l’imageries, quant à elles, ne sont pas modifiées. [less ▲]

Introduction: Patellar tendinopathy, often remain rebel to conservative treatments. Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic patellar tendinopathy. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment. They were also invited to answer to questionnaire relative to pain and functional status. PRP was obtained from autologous blood using an apheresis system (COM.TEC, Fresenius). The injection of 6mL of PRP was realised without local anaesthesia into the proximal insertion of the patellar tendon. A 48h rest-time was recommended after infiltration. Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painkillers. Results: At this time, 10 patients with patellar tendinopathy were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved in all patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with patellar tendinopathy 6 weeks after treatment. All the 10 patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved. [less ▲]

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. Materiel and methods: This study compared the effects of two methods of training (eccentric (E) training and concentric (C) training) with untrained (U) rats. The animals underwent training over a period of five weeks. The tricipital, patellar and Achilles tendons were subsequently removed to perform a traction test to the point of tendon rupture, and a histological analysis was performed. Results: There was a significant improvement 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-section than the E- and C-trained groups. No significant difference was observed for the constraints between the three groups for all three tendons. However, a tendency towards improvement was observed between the trained and the U groups for the patellar tendon. Histological studies demonstrated the development of a greater number of blood vessels and a larger quantity of collagen in the eccentric group. Discussion and conclusion: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. [less ▲]

Introduction: Tendinopathies, especially upper patellar tendinopathy also known as jumper’s knee, often remain rebel to conservative treatments. Several experimental studies have shown the healing properties of platelet and their growth factors. These factors have the potentiality to improve healing of different tissues: bones, muscles, tendons... Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. On the other hand, such treatment has been totally removed of list of doping treatments. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic jumper’s knee. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment.

Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painbrakers. Our protocol was approved by Ethic Committee of University and University Hospital of Liège. Results: Eighteen patients with jumper’s knee were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved for the majority of the patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with jumper’s knee 6 weeks after treatment. Most patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved. A followup at 3 months is actually in process to evaluate more long term efficacy of PRP treatment. [less ▲]

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 ▲]

This study showed some difference in trunk and knee extensors strength between rowers and control subjects as well as between rowers and non-rowing athletes. The increased performances of extensor muscles in elite rowers appear to be probably related to the specificity of this sport. In the drive phase of rowing, rowers sequentially push with the legs and then pull with the arms and lower back, requiring both muscular strength and endurance. However, no difference was shown between groups regarding dynamic and static trunk extensor endurance. Further study is required to clarify if trunk and knee muscle strength and/or endurance are related to rowing performance. [less ▲]
