Platelet-rich plasma (PRP) may represent a new therapeutic option for chronic tendinopathies. Platelets release various cytokines and growth factors which promote angiogenesis, tissue remodeling, and wound healing. We made an exhaustive review of the use of PRP in chronic tendinopathies: epicondylitis, rotator cuff, patellar and calcaneal tendinopathies, and plantar fasciitis. Medline, Embase and Google Scholar were used (until July 31, 2012). Clinical studies about PRP and tendinopathies (in English and French language peer-reviewed journals) were included. Articles with a high level of evidence were considered preferentially. Despite the proven efficacy of PRP on tissue regeneration in experimental studies, there is currently scanty tangible clinical evidence with respect to chronic tendon disorders. The few studies that have been performed appear unlikely to be comparable. Randomized controlled studies with appropriate placebo groups are needed to determine the real effectiveness of PRP for treating chronic musculoskeletal injuries. [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. Even if the mechanotransduction theory is commonly accepted, the physiology of tendons is not clearly understood. We aimed to better define the biomechanical and histological changes that affect healthy tendon after eccentric and concentric training. Materiel and Methods: This study compared the effects of 2 methods of training (eccentric (E) training and concentric (C) training) with untrained (U) rats. The animals were trained over a period of 5 weeks. The tricipital, patellar and Achilles tendons were removed, measured and a tensile test until failure was performed. A histological analysis (hematoxylin and eosin and Masson's trichrome stains) was also realized. Results: There was a significant increase 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-sectional area than the E- and C-trained groups, but none was constated between E and C groups. No significant difference was observed for the mechanical stress between the three groups for all three tendons. Histological studies demonstrated the development of a greater number of blood vessels and a larger quantity of collagen in the E group. Discussion and conclusion: 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 healing of tendon. [less ▲]

Background: Fatigue, lack of motivation and low compliance can be observed in nursing home residents during the practice of physical activity. Because exercises should not be too vigorous, whole body vibration could potentially be an effective alternative. The objective of this randomized controlled trial was to assess the impact of 3-month training by whole body vibration on the risk of falls among nursing home residents. Methods: Patients were randomized into two groups: the whole body vibration group which received 3 training sessions every week composed of 5 series of only 15 seconds of vibrations at 30 Hz frequency and a control group with normal daily life for the whole study period. The impact of this training on the risk of falls was assessed blindly by three tests: the Tinetti Test, the Timed Up and Go test and a quantitative evaluation of a 10-second walk performed with a tri-axial accelerometer. Results: 62 subjects (47 women and 15 men; mean age 83.2 ± 7.99 years) were recruited for the study. No significant change in the studied parameters was observed between the treated (n=31) and the control group (n=31) after 3 months of training by controlled whole-body-vibrations. Actually, the Tinetti test increased of + 0.93 ± 3.14 points in the treated group against + 0.88 ± 2.33 points in the control group (p = 0.89 when adjusted). The Timed Up and Go test showed a median evolution of - 1.14 (− 4.75-3.73) seconds in the treated group against + 0.41 (− 3.57- 2.41) seconds in the control group (p = 0.06). For the quantitative evaluation of the walk, no significant change was observed between the treated and the control group in single task as well as in dual task conditions. Conclusions: The whole body vibration training performed with the exposition settings such as those used in this research was feasible but seems to have no impact on the risk of falls among nursing home residents. Further investigations, in which, for example, the exposure parameters would be changed, seem necessary [less ▲]

Introduction. Low back pain (LBP) is common among athletes and can be challenging for athletic trainers and therapists. Unfortunately, little is known about symptoms associated with functional lumbar segmental instability (FLSI) in athletes with LBP. Purpose. To determine subjective and objective symptoms associated with FLSI in athletes with LBP. Materials and Methods. We included 24 male athletes (12 soccer players and 12 tennis players) with non specific LBP mean (± standard deviation) pain intensity (0-100 Visual Analogue Scale) and disability (0-24 Roland-Disability questionnaire) scores reaching respectively 35 (±20) and 4 (±3). Athletes were submitted to a standardized anamnesis (including subjective identifiers of FLSI) and a clinical assessment conducted by a manual therapist who explored objective identifiers of FLSI. Results. According to the manual therapist, 12 athletes (6 tennis and 6 soccer players) presented a FLSI. The two groups did not differ regarding pain intensity and disability (P>0.05). However, athletes with FLSI appeared significantly younger than non FLSI athletes (P<0.01). Only three subjective identifiers appeared significantly related to FLSI in soccer and tennis players with LBP: “reports frequent episodes of muscle spasms”, “reports feelings of giving way or back giving out” and “Pain increased with sudden, trivial, or mild movements”. Regarding objective identifiers of FLSI, “positive prone instability test”, “aberrant movement during active and passive trunk flexion-extension“ and “poor lumbopelvic control” were significantly related to FLSI in these athletes. Conclusions. In this preliminary study, 50% of the athletes with LBP presented a FLSI. Some subjective and objective symptoms are significantly related to FLSI in soccer and tennis players. Implications. Athletes with LSI should be targeted for retraining to restore normal movement control. [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. 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, the few studies of high level of evidence are contradictory. 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 ▲]
