This study was undertaken by the University of Calgary Sport Medicine Centre, Physical Therapy Section. Financial support for the study was provided by a grant from the BE Schurr Memorial fund and the Canadian Physiotherapy Association (Calgary District). Information on the relative strengths of the muscles that internally and externally rotate the hip is scant. The present study used a Cybex(R) 340 isokinetic dynamometer to investigate hip rotation strength in 60 normal subjects. Subjects performed maximum internal and external hip rotation movements in each of three different testing positions. Results showed that hip rotation torques were significantly dependent on testing position (p < 0.05). Highest torques were obtained using a "seated" position, while a supine position with the knee flexed produced stronger torques than a supine position with the knee extended. Within each test position, internal rotation torques exceeded external rotation torques in all but one situation (p < 0.05). These findings contradicted previous reports that external rotation was the stronger of the two movements. Overall, the results provided valuable normative data on the relative strength proportions of the hip rotation musculature. J Orthop Sports Phys Ther 1992;16(1):43-50.
这项研究由卡尔加里大学运动医学中心物理治疗科进行。研究得到了 BE Schurr 纪念基金和加拿大物理治疗协会（卡尔加里地区）的资助。有关髋关节内、外旋转肌肉相对强度的信息很少。本研究使用 Cybex（R）340 等速测力计对 60 名正常受试者的髋关节旋转力量进行了研究。受试者在三种不同的测试位置分别进行最大髋关节内、外旋转运动。结果表明，髋关节旋转扭矩明显依赖于测试位置（p < 0.05）。采用“坐姿”时获得的扭矩最大，而屈膝仰卧位产生的扭矩比伸膝仰卧位强。在每个测试位置，除一种情况外（p < 0.05），内旋扭矩均大于外旋扭矩。这些发现与先前关于外旋是两种运动中较强的运动的报告相矛盾。总体而言，这些结果提供了髋关节旋转肌肉相对强度比例的有价值的正常数据。J Orthop Sports Phys Ther 1992;16(1):43-50.
