Objectives: The focus of this study is to assess the trunk muscles strength using isokinetic dynamometer then tries to find a relation between back pain and trunk muscles strength. Materials and Methods: Fifty patients with back pain (BP) and 50 healthy subjects were recruited in this study. The flexors and extensors of the trunk muscles were evaluated by Isokinetic dynamometer and compared with control groups. Results: Patients with acute back pain show a significant reduction of the trunk muscles strengths at 120°/s velocities (p value < 0.05) with reversed flexor/extensor ration in comparison with sound subjects. Such a relationship does not show in subacute or chronic back pain patients. Conclusions: Acute back pain associated with decreased the strength of the trunk flexors and extensors at 120°/s. The trunk muscle reinforcement programs must be considered in-patients with acute back pain.展开更多

The aim of this study was to describe the peak isokinetic torque of the knee in professional football players of different League divisions in Cyprus and assess bilateral and unilateral asymmetries of strength. METHODS： Four hundred and twenty-nine professional male football players participated in this study （Division 1, n = 245 and Division 2, n = 184）. The isokinetic muscle function of the knee was measured using the Humac Norm Testing and Rehabilitation system （CSMi Medical ＆ Solution, USA）. Measurements were collected at angle speeds of 60 °/sec and 300 °/sec, for 3 and 25- repetitions respectively. RESULTS： At both angle speeds, peak isokinetic torque of the knee joint was significantly higher in the right and left knees of players in Division 1 （D1） compared to those competing in Division 2 （D2）. At both testing speeds, peak flexor torque of the left hamstrings was significantly higher in players participating in Division 1 compared to those competing in Division 2. The right hamstrings yielded similar results, except at 60 °/sec, where no difference was found between the groups. CONCLUSION： This study provides valuable data regarding the forces produced by the lower body of football players participating in D1 and D2 in Cyprus, whilst also disclosing there to be no bilateral imbalances or abnormal H/Q ratios. The results of this study may provide pertinent information that can be used by the coaching staff for training and recruiting purposes.展开更多
