Background: Patients with hypermobility suffer from joints problems and chronic pain is the most frequently reported symptom. Objective: Eccentric muscle strengthening could be very important to protect hypermobile joints. Design: Case report. Patient: A girl (16 y.o.) affected by an Ehler-Danlos syndrome presented pain in the right elbow and the right wrist after a season of tennis. Interventions: Her training consisted of wrist prono-supination and flexion-extension muscle group reinforcement and proprioceptive training. To protect the wrist against excessive load, the eccentric strengthening exercises of prono-supinator and flexor-extensor muscles of elbow and wrist were undertaken gradually, at increasing speeds within a limited range of motion in flexion and extension, on an isokinetic device after an evaluation. She was also given an orthesis restricting the joint range of motion of the wrist. Main outcome measurements: The evaluation was made by isokinetic evaluation, visual analog scale and MOS-SF36 questionnaire before and after training. Results: The patient rapidly noted a decrease in pain and an increase in the stability of her right arm even when playing tennis. Isokinetic evaluation objectified a significant improvement in maximal torque in flexion-extension muscles of the right elbow. She was also given individualized home exercises. Conclusions: The goal of this eccentric training is to avoid hypermobility by using the muscles as a protective brake in the control of joint positioning. Muscles can be reinforced in eccentric mode with starting position at the maximum length of these muscles when unstreched. The exercises can be carried out safely on an isokinetic device, at slow speed and limited range of joint motion to avoid risk of luxation. Thus, in this case report, the eccentric exercises using an isokinetic device were effective to safely reinforce the muscles as a protective brake for joint hypermobility and prevent pain during practicing tennis.

The muscle-tendon pathologies remain very common in sport as well as to manual workers. An action of primary and secondary prevention is crucial if we are to prevent the occurrence of these pathologies and prevent recurrence. The eccentric contractions marked by the removal of muscle insertions, gives them certain preventive and rehabilitative characteristics. It is now clearly shown that the eccentric work applied to the muscle-tendon complex, leads to progressive structural changes. These adaptations allow the muscles and tendons to better suit external stresses under which they are subjected and thereby reduce the lesion risk but also to prevent recurrence. Finally, it is also accepted that only the sub maximal eccentric exercise gradually increased helped protect (up to 1 year) of Delayed Onset Muscle Soreness in case of severe and unusual eccentric work.

Platelet-rich plasma (PRP) contains a large quantity of growth factors, which may enhance tendon healing processes. Local infiltration of PRP represents a relatively new treatment for tendinopathies. To date, no side effects have been reported after infiltration of PRP to treat tendinopathy. We reported a case of exuberant inflammatory reaction after one infiltration of PRP to treat jumper’s knee in a type 1 diabetic patient who was 35 years old. Injections of PRP must be proposed after careful consideration for patients with morbidity risks linked to insulin-dependent diabetes. [less ▲]

Les traitements «passifs» des tendinopathies sont généralement utilisés de manière empirique pour combattre la douleur mais ne modifient pas la structure histologique du tendon. Par contre, le travail excentrique a pour but de contrecarrer une théorie étiopathogénique proposant une insuffisance de résistance du tendon exposé à des charges externes qui peuvent progressivement entrainer des lésions. Les résultats cliniques suite à cette prise en charge montrent souvent une évolution favorable des douleurs. Les ondes de choc extra-corporelles demeurent une option thérapeutique non-invasives et présentent peu de complications. De plus, elles sont employées avec succès pour traiter des tendinopathies chroniques rebelles aux traitements conservateurs classiques. Le plasma riche en plaquettes (PRP) est obtenu par centrifugation de sang autologue afin d’obtenir une grande concentration plaquettaire dépendant de la technique employée. Malgré la preuve de l’efficacité du PRP sur la régénération tissulaire en laboratoire, il existe actuellement peu de preuves cliniques tangibles concernant le traitement des tendinopathies chroniques. Enfin, d’autres nouvelles options thérapeutiques (patches de dérivés nitrés, infiltrations de polidocanol, d’acide hyaluronique et de cellules souches) sont également abordées. [less ▲]

Introduction: Different series emphasized the necessity of rehabilitation program after infiltration of platelet-rich plasma (PRP) in case of tendinopathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods: After a review of literature of post-PRP infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A a standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results: The VAS , IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusion: We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP infiltrations in case of patellar tendinopathy. [less ▲]

The curative and preventive efficiency of the isokinetic exercise, especially of the eccentric contraction, has been well demonstrated. However, intense or unusual eccentric exercise is known to induce muscle damage associated with delayed-onset muscle soreness (DOMS) and prolonged functional deficits. These negative consequences can frequently disturb the progress of re-education or training programmes. Since they can affect athletic performance and increase the risk of musculo-skeletal injuries, the structuro-functional alterations associated with DOMS may also be problematic in athletes. Therefore, to optimize the benefits of the eccentric work while avoiding muscle damage and occurrence of DOMS should represent a major objective for the practitioners. To date, the only systematic intervention that brings muscle protection against DOMS consists of performing repeated eccentric sessions at submaximal intensity. Besides its clinical use, isokinetic constitutes an interesting model to generate and investigate the DOMS phenomenon. The original association of eccentric injuring protocols with new emerging techniques of molecular biology appears to be a promising strategy to better understand the cellular and molecular mechanisms underlying exercise-induced muscle damage. Such data would provide better guidelines for prevention or treatment practice. [less ▲]

Some authors claim that occlusal appliances can enhance athletic performance. Therefore this study investigated the influence of dental occlusion on knee muscle strength performance. Twelve healthy female subjects (mean age 24.1 +/- 3.1 years) without temporomandibular joint dysfunction participated in this study. Isokinetic quadriceps and hamstring strength were assessed in relation to three randomized jaw conditions: mouth closed in maximum intercuspidation without splint, mouth closed on a balanced splint which optimized contact over the dental arch, mouth closed on a piece of resin of 1 mm which created an imbalanced occlusion. Tests were performed at 60 degrees /s and 240 degrees /s in concentric and 30 degrees /s in eccentric exertions. Concentric performances did not show any significant difference between the 3 jaw conditions (p > 0.05). By contrast, in the eccentric trials related to quadriceps performance, significant differences (p < 0.05) were observed between the resin condition and the two other modalities (without splint or with a balanced splint). The imbalanced occlusion created by the resin component corresponded to an average decrease of 9% in eccentric peak torque. The eccentric hamstring peak torques also showed a significant difference (p < 0.05) between measurements with splint and with resin (7% decrease when occlusion was imbalanced). In conclusion, among asymptomatic females, artificial imbalanced occlusion induces immediate and significant alteration of knee eccentric muscle performances. Therefore, occlusion examination should be undertaken on a regular and frequent basis for high-level athletes. Moreover, for athletes using mouthguards, muscular performance assessments should be planned with and without the dental protection. [less ▲]

Human-structure interactions are not completely understood yet. This paper presents an experimental study focusing on the interaction between a human and a flexible support, with a major aim to better understand how the behavior of a human subject, bouncing on a flexible structure, adapts to the support motion. Exploratory experiments are undertaken with a 7m-span timber footbridge tested in the Human Motion Analysis Laboratory of the University of Liege. The movements of the coupled system composed of the subject and the footbridge are recorded by Motion Capture technology; the subject\textquoteright{}s 3-D body motion is defined by three important angles: ankle, knee and hip. The interaction between the subject and the footbridge is also quantified by means of force platform measurements. The experiments indicate an influence of the support amplitude and natural frequency on the phase shift between the oscillatory floor motion and the three angles characterizing the motion. [less ▲]

Objectives.– To assess the feasibility and the effects of a strengthening program for people with Parkinson's disease (PD). Methods.– Fourteen patients with Hoehn and Yahr stage [1] < III of PD were allocated to either 24 sessions of strength training (ST group; n = 8) or to a control group (C group; n = 6) for 3 months. Concentric knee muscle strength and a maximal cycling incremental test were performed at baseline and after training. Training consisted of progressive resistive exercises on leg press, leg extension, leg curl, between 50 and 80% of 1RM and was completed by non-instrumented exercises for trunk and upper limbs muscles. Anxiety, depression and quality of life were assessed using questionnaires. An Anova for repeated measures was used for statistical analysis. Results.– Six patients of the ST group (75%) fully completed the program. There were significant “group by time” effects for all knee muscles strength measures of less involved side (P < 0.05). A significant “group by time” effect was also found for knee flexors of the most involved side, but only at angular speed of 180°/s (P = 0.03). Patients of ST group also increased maximal aerobic power (+13%) whereas patients of C group decreased their performances (–9%; “group by time” effect, P = 0.04). No changes in anxiety, depression or quality of life could be highlighted. Conclusions.– The increase of some strength measures in ST group showed that progressive strength training counteracts strength decrease among people with Parkinson's disease. Strengthening also had a positive effect on maximal aerobic power. [less ▲]
