The purpose of this study was to quantify and report the intrarater and interrater reliability of hip internal rotation (IR) range of motion supine with the hip and knee at 90° of flexion and for the flexion-adduction-internal rotation (FADIR) test. Hip internal rotation measured in a lying supine position with the hip and knee at 90° of flexion revealed information on hip impairments. To date no simple quantification approach has been presented in this position; therefore, the FADIR test has not been quantified yet.
Twenty participants (mean ± standard deviation [SD] age, 24.0 ± 2.1 years; 10 women and 10 men) without lower-limb or back pain were recruited. Three raters evaluated each participant during 2 testing sessions, 1 day apart. A built-in smartphone compass application was used to obtain the hip IR range of motion in both procedures.
Mean (± SD) supine IR was 51.7° (± 9.7°) and 62.6° (± 11.4°) for men and women, respectively. Concerning the FADIR test, mean values were 41.8° (± 9.64°) and 50.1° (± 8.0°) for men and women, respectively. The mean intrarater and interrater reliability coefficients were 0.80 and 0.72 for hip IR and 0.75 and 0.40 for the FADIR test. The standard error of the mean ranged from 4.8° to 8.3° (minimal detectable difference [MDD], 13.3° to 22.9°) for hip IR and from 4.6° to 10.3° (MDD, 12.8° to 28.6°) for the FADIR test.
Overall, the smartphone compass application is adequate to quantify hip IR in a lying supine position. However, the poor to moderate interrater reliability in the FADIR test and the size of the MDD values suggest that the FADIR test should be standardized.
本研究旨在定量并报告髋关节内旋（IR）在仰卧位时，髋关节和膝关节屈曲 90°的重复性，以及用于测量髋关节内旋的屈伸内收内旋（FADIR）试验的重复性。髋关节在仰卧位时，髋关节和膝关节屈曲 90°，可以提供有关髋关节损伤的信息。迄今为止，尚未在这个位置提出简单的量化方法；因此，尚未对 FADIR 试验进行量化。
20 名参与者（平均年龄 ± 标准差[SD]，24.0 ± 2.1 岁；女性 10 名，男性 10 名），无下肢或腰背疼痛，参与了这项研究。3 名评估者在 2 天的时间内，分别对每位参与者进行了 2 次测试。使用内置的智能手机指南针应用程序，在这两种程序中获取髋关节的内旋范围。
男性和女性的仰卧位内旋分别为 51.7°（± 9.7°）和 62.6°（± 11.4°）。对于 FADIR 试验，男性和女性的平均数值分别为 41.8°（± 9.64°）和 50.1°（± 8.0°）。髋关节内旋的平均组内和组间可靠性系数分别为 0.80 和 0.72，FADIR 试验的平均组内和组间可靠性系数分别为 0.75 和 0.40。均值的标准误差范围为 4.8°至 8.3°（最小可检测差异[MDD]，13.3°至 22.9°），用于髋关节内旋，4.6°至 10.3°（MDD，12.8°至 28.6°），用于 FADIR 试验。
总的来说，智能手机指南针应用程序足以在仰卧位时定量测量髋关节内旋。然而，FADIR 试验的组间可靠性较差，且 MDD 值较大，表明 FADIR 试验应标准化。
