Introduction: Infiltration of PRP may be used as a recent therapeutic option for chronic tendinopathies The aim of the current study is to evaluate the clinic and the return to sports activities in patients with chronic upper patellar tendinopathies 1 year after 1 infiltration of PRP. Material and methods: The follow-up of 20 subjects who beneficed from 1 infiltration of PRP was made before infiltration, after 3 months and 1 year after infiltration; it was made as follow: VAS, IKDC and VISA-P scores. Moreover, they had to answer an information questionnaire concerning their life and sports activities. Results: Seventy percents of patients reported a favourable evolution with decrease of pain, 10% did never report any improvement and 20% were treated surgically. Eighty-seven percents returned to sports activities without any pain, and 50% of them recovered the same sport level. VAS has significantly (p<0.0001) dropped, IKDC significantly improved (p=0.0007) and VISA-P also significantly increased (p=0.0087) over the follow-up of 1 year. Discussion: This study confirms that a local injection of PRP coupled with a program of eccentric rehabilitation through a chronic Jumper's knee, improves painful symptoms and the functionality of the subjects’ knee up to a follow-up of 1 year.

Background: Even if eccentric exercises appear favourable in primary prevention of tendons lesions and, especially, in secondary prevention after tendinopathy, the biomechanical changes to the tissue are not yet clear. Objective: We aimed to better define the biomechanical changes that affect healthy tendon after eccentric and concentric training. Design: Randomised controlled trial. Participants: Eighteen Sprague-Dawley rats of 2 months. Interventions: The six rats in the control group (U) were not subjected to physical exercise. The 12 remaining rats (6 in each group) ran on a treadmill set at a +15° incline for concentric training (C) or a -15° incline for eccentric training (E), at a speed of 17 m/min for 1 h, three times per week for 5 weeks. Main Outcome Measurements: The tricipital, patellar and Achilles tendons were subsequently removed to perform a traction test until 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, but none between E and C groups. No significant difference was observed for the mechanical stress at rupture per surface unit between the three groups for all three tendons. However, a tendency towards improvement these values was observed between the trained and the U groups for the patellar tendon. Histological studies demonstrated the tendency of the development of a greater number of blood vessels and a larger quantity of collagen in the eccentric group. Conclusions: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. Our results partly explained how mechanical loading, especially in eccentric mode, could improve the tendon structure. [less ▲]

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.

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 ▲]

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.

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 ▲]

Study Design. Observational prospective study.Objective. Our objective was to assess the reliability and validity of the French version of the Keele STarT Back Screening Tool (SBST).Summary of Background Data. The SBST is a recently validated tool developed to identify subgroups of patients with low back pain (LBP) to guide early secondary prevention in primary care.Methods. Outpatients with LBP aged 18 years or more, attending a rehabilitation centre, a back school, a private physiotherapy unit or a fitness centre were included. Patients were assessed through the SBST, Roland-Morris Disability Questionnaire (RMDQ), Orebro Musculoskeletal Pain Screening Questionnaire (OMPSQ), Medical Outcomes Survey Short Form 36 (SF-36) questionnaire, and a pain visual analogic scale (VAS). Test-retest reliability was assessed with Kappa score or the intraclass correlation coefficient (ICC), internal consistency of the psychological subscale with the Cronbach alpha coefficient, construct validity with the Spearman's correlation coefficient, and floor and ceiling effects by percentage frequency of lowest or highest possible score achieved by respondents.Results. 108 patients with LBP were included. The test-retest reliability of the SBST total score was excellent with an ICC of 0.90 (0.81-0.95). The Cronbach alpha coefficient was 0.73 showing a good internal consistency for the psychological subscale. High Spearman's correlation coefficients of 0.74 between SBST and RMDQ, and 0.74 between the SBST and OMPSQ were observed. As expected, low to moderate correlations were observed between the SBST total score and some dissimilar measures of the SF-36. The lowest possible SBST score was observed for 8 patients (7.4%) whereas only three patients (2.8%) had the highest possible SBST score.Conclusion. The French version of the SBST is a reliable and valid questionnaire consistent with the original English version. Therefore, this new version may help French-speaking clinicians and scientists to stratify patients with LBP. [less ▲]

BACKGROUND: We have previously shown that short sessions of whole body vibration (WBV) were not able to significantly improve fall risk among nursing home residents but some trends towards an improvement of motor capacity were observed. OBJECTIVE: The objective of the present study was to evaluate the impact of 6-month training by WBV on functional and motor abilities among nursing home residents observed over a 12-month period. METHODS: Patients were randomized into two groups: the WBV group which received three training sessions every week composed of five series of 15 s of vibration at 30 Hz intensity for a period of 6 months and a control group with normal daily life. The impact of this training on the risk of falls was assessed blindly after 6 and 12 months by the Tinetti Test, the "Timed Up and Go" test and a quantitative evaluation of a 10-s walk performed with a tri-axial accelerometer. The occurrence of falls was also observed. RESULTS: 62 elderly healthy volunteers, (47 women and 15 men, mean age 83.2 +/- 7.9 years) were included in this study. There was no significant difference between the two groups regarding the Tinetti test (p = 0.75), the "Timed Up and Go" test (p = 0.19) and the Locometrix(R) test, except for the step length, measured by dual task (p < 0.01). No significant inter-group difference in the frequency of falls was observed during the 12 months of research. A total of 42 falls were recorded during the first 6 months of experimentation: 24 falls in the treated group and 18 in the control group (p = 0.60). During the next 6 months, 19 falls occurred: 8 falls in the treated group and 11 in the control group (p = 0.52). CONCLUSION: This study failed to establish the effectiveness of low doses of WBV, under the conditions used in our study, on functional and motor abilities of institutionalized elderly patients. However, given the positive results of other studies, further investigations, with modified therapeutic protocols, seem necessary to clarify the effects of WBV in the elderly. [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 ▲]

Clinical benefits and CT healing were obtained within 2 months of teriparatide initiation and denosumab withdrawal. Increase in bone turnover previously described, when denosumab treatment is removed, might have a synergistic effect to the stimulating effect of teriparatide on bone remodeling to promptly heal osteonecrosis of the jaw.

Osteonecrosis of the jaw (ONJ) is a clinical condition associated with long-term exposure to inhibitors of bone resorption, mainly bisphosphonates. Denosumab (DMab) is a human monoclonal antibody of the receptor activator of nuclear factor kappa-B ligand. It prevents osteoclast-mediated bone resorption and is widely prescribed for the management of postmenopausal osteoporosis. Whereas ONJ has already been reported in women treated with DMab, we report for the first time the development of ONJ, following tooth extraction, in a male patient treated for idiopathic osteoporosis with DMab. Due to the constant increase in DMab prescription, for the management of osteoporosis, in both genders, physicians should be made aware of this potential risk. [less ▲]
