The assessment of human muscle strength is of considerable value in various pathological states with modifications of the performance level. The original concept of isokinetic dynamometry provides a precise and reliable quantification of strength. Identification of underlying deficits in bilateral and reciprocal muscle group relationships plays a great role in the treatment of anterior cruciate ligament (ACL) reconstruction and muscle injuries. The value of this type of assessment for prevention in uninjured subjects practicing sports at risk is suggested. Rehabilitative use of isokinetic includes muscle strengthening and tendinitis treatment by means of eccentric exercises. [less ▲]

Background: Cryopreservation of cortex ovarian tissue before anti-cancer therapy is a promising technique for fertility preservation mainly in children and young women. Ischemia in the early stage after ovarian graft causes massive follicle loss by apoptosis. VEGF111 is a recently described VEGF isoform that does not bind to the extracellular matrix, diffuse extensively and is resistant to proteolysis. These properties confer a significantly higher angiogenic potential to VEGF111 in comparison to the other VEGF isoforms. Methods: We evaluated the morphology of cryopreserved sheep ovarian cortex, grafted in the presence or absence of VEGF111. Ovarian cortex biopsies were embedded in type I collagen with or without VEGF111 addition before transplantation to SCID mice ovaries. Transplants were retrieved 3 days or 3 weeks later. Follicular density, vasculature network, haemoglobin content and cell proliferation were analysed. Results: Addition of VEGF111 increased density of functional capillaries (p=0.01) 3 days after grafting. By double immunostaining of Ki-67 and von Willebrand Factor (vWF) we demonstrated that proliferating endothelial cells were found in 83% of the VEGF111 group when compared to 33% in the control group (p=0.001). This angio-stimulation was associated with a significant enhancement of haemoglobin content (p=0.03). Three weeks after transplantation, the number of primary follicles was significantly higher in VEGF111 grafts (p=0.02). Conclusion: VEGF111 accelerates blood vessels recruitment, functional angiogenesis and improves the viability of ovarian cortex by limiting ischemia and ovarian cortex damage. [less ▲]

The scapula plays an important role in normal shoulder function. In sports in which demands on the shoulder are extremely high, the quality of movements depends on the interaction between scapular and glenohumeral kinematics. Comparatively to a normal status, the scapular dyskinesis is defined as observable alteration in the position of the scapula and in the patterns of scapular motion in relation to the thoracic cage [1]. Surprisingly, only sparse literature focused on the isokinetic assessment of scapulothoracic muscles. To our knowledge, only Cools et al. [2,3] have investigated such evaluation, using a closed kinetic chain system. The aim of this study was to provide new insights in the isokinetic assessment of the scapular muscle performances, among sedentary and overhead athletes populations. 10 sedentary men (23.5  2.6 years; 67.3  62 kg) and 10 overhead athletes (22.2 +/- 2.3 years; 72.9 +/- 9.7 kg) participated into the study. All subjects were free of previous shoulder pathology. The overhead population included 2 volleyball, 2 handball, 3 tennis and 3 badminton players, all with at least 9 years of intensive practice. They sustained a bilateral isokinetic assessment (Biodex 3 dynamometer) of the protractors (PRO) and retractors (RET) of the scapula (closed kinetic chain). Subjects were seated and the closed kinetic chain attachment was placed in a horizontal plane, at 30° from the frontal plane, which corresponded to the scapular plane; the elbow was placed in full extension. The range of motion was individualized from the maximal protraction to the maximal retraction positions. After a specific warm up using an elastic theraband and familiarization on the isokinetic device, the isokinetic protocol consisted in 3 repetitions at slow speed (12.2 cm/s) and 5 repetitions at high speed (36.6 cm/s). The strength performances (peak-force in N) and ratios (Protractors / Retractors; PRO/RET) are described in Tables 1 and 2. The maximum force developed by scapular muscles decreased with increase in motion velocity. Generally, there was no dominance effect, except for the RET at high speed within the sedentary population (Table 1). The PRO/RET ratios remained inferior to 1 indicating higher performances on RET muscle group (Table 2). Even if the athletes recruited in our study used their shoulder in an asymmetrical way, we did not find any significant difference between the dominant and non dominant ratios in that population; only the PRO/RET ratio of sedentaries at high speed showed a dominance effect. The PRO/RET ratios were higher into the athletes, yet the difference did not reach statistical significance. There was no significant difference between both populations, if considering the absolute strength or the bodyweight normalized peak force. The sports population appeared more homogenous with lower standard deviation values for all data. Nevertheless, in such closed kinetic chain assessment, compensations of the trunk during protraction and of the elbow during retraction must be strictly controlled. The shoulder assessment in a closed kinetic chain allowed to investigate the force developed by the protractors and the retractors of the scapula. In spite of upper limb asymmetrical use through overhead activities, a dominance effect in strength performances or agonist-antagonist ratios was not detected among athletes recruited in that study. These preliminary results could be useful for further comparison with pathological cases. REFERENCES 1. W.
