[Purpose] To investigate the difference by degrees in total hip rotation range of motion (ROM) between sides and with regard to gender in healthy young Japanese adults. [Participants and Methods] Data from previously published studies were used. We utilized the left and right hip rotation ROM of 205 Japanese participants aged 18 to 25 years, who satisfied the inclusion criteria and were randomly measured three times in the prone position by the double-blind method. The average value of the three measurements was used to calculate the left-right difference of the hip total rotation ROM in the hip joints, which is the sum of the hip internal and external rotation ROM. We investigated the distribution of the total hip rotation considering the flexibility factor and its relationship with gender. [Results] We confirmed that there were seven participants with 2 SD or more and two with 3 SD or more. No significant difference was found in the left-right difference in the total hip rotation ROM, regardless of gender. [Conclusion] The distribution of left-right differences in the total hip rotation ROM in healthy young adults showed the existence of a significant left-right difference of 2 SD or more.
[目的] 调查健康年轻日本成年人两侧髋关节总旋转活动范围（ROM）的度数差异以及性别差异。[参与者与方法] 使用先前发表研究的数据。我们纳入了205名年龄在18至25岁之间的日本参与者，他们满足纳入标准，并通过双盲法在俯卧位对其左右髋关节旋转ROM进行了三次随机测量。三次测量的平均值用于计算髋关节总旋转ROM的左右差异，即髋关节内旋和外旋ROM之和。我们考虑柔韧性因素研究了总髋关节旋转的分布及其与性别的关系。[结果] 我们确认有7名参与者的差异在2个标准差或以上，2名参与者的差异在3个标准差或以上。无论性别如何，总髋关节旋转ROM的左右差异均未发现显著差异。[结论] 健康年轻成年人总髋关节旋转ROM的左右差异分布显示存在2个标准差或以上的显著左右差异。
