A general lack of descriptive details exists for measurements of hip rotation range of motion. This study was designed to establish the influence of gender and hip flexion position on active range of motion of the hip in external and internal rotation. Sixty (39 females and 21 males) healthy college-age (21.8 +/- 1.7 years) subjects were studied. Hip rotation of the dominant leg of each subject was measured in the prone (hip near 0 degree of flexion) and seated (hip near 90 degrees of flexion) positions using a standard goniometer. Data were analyzed using an analysis of variance model. Pearson's r statistics were used to determine the degree of association between measurements of hip rotation made seated vs. prone. A statistically significant difference (p < 0.05) was found between mean hip external rotation (ER) measured seated (36 +/- 7 degrees) and mean hip ER measured prone (45 +/- 10 degrees). Conversely, mean hip internal rotation (IR) measured seated (33 +/- 7 degrees) was not statistically different than mean hip IR measured prone (36 +/- 9 degrees). Females had statistically more active hip internal and external rotation than males (p < 0.05). A moderate degree of association existed between measurements of hip ER taken in the prone vs. seated position (r = 0.57, p < 0.05). For IR, the degree of association between the two measurement positions was slightly higher (r = 0.72, p < 0.05). Unlike the amount of active hip internal rotation which showed little difference between measurements made prone vs. seated, our data indicate that measurement position had a significant effect on the amount of active range of motion of the hip in ER. These findings are clinically significant for they stress the importance of documenting measurement position. They also stress the need for representative norms to be established for each hip position and gender.
关于髋关节旋转活动范围的测量，普遍缺乏描述性细节。本研究旨在确定性别和髋关节屈曲位置对髋关节主动外旋和内旋活动范围的影响。对60名（39名女性和21名男性）健康的大学年龄（21.8±1.7岁）受试者进行了研究。使用标准角度计在俯卧位（髋关节接近0度屈曲）和坐位（髋关节接近90度屈曲）测量每个受试者优势腿的髋关节旋转。数据采用方差分析模型进行分析。使用Pearson相关系数r统计量来确定坐位与俯卧位髋关节旋转测量值之间的关联程度。发现坐位时测量的平均髋关节外旋（ER）（36±7度）与俯卧位时测量的平均髋关节ER（45±10度）之间存在统计学显著差异（p<0.05）。相反，坐位时测量的平均髋关节内旋（IR）（33±7度）与俯卧位时测量的平均髋关节IR（36±9度）在统计学上无差异。女性的髋关节主动内旋和外旋在统计学上比男性更多（p<0.05）。俯卧位与坐位时髋关节ER测量值之间存在中度关联（r = 0.57，p<0.05）。对于IR，两个测量位置之间的关联程度略高（r = 0.72，p<0.05）。与髋关节主动内旋量在俯卧位和坐位测量时差异不大不同，我们的数据表明测量位置对髋关节ER的主动活动范围量有显著影响。这些发现具有临床意义，因为它们强调了记录测量位置的重要性。它们还强调了需要为每个髋关节位置和性别建立代表性规范。
