The Flexion ABduction External Rotation (FABER) test is typically used as a provocation special test, but has also been used as a measurement of combined hip range of motion (ROM). It is thought that limited ROM with this measurement may be indicative of hip pathology. To date, normative data, reliability, and minimal detectable change (MDC) of such measurements have not been established.
To determine normative FABER height, assess inter- and intra-rater reliability and MDC for FABER, and compare traditional FABER measurements to methods which account for differences in thigh length.
Descriptive laboratory reliability study.
Nineteen healthy participants without low back, hip, or knee pain in the preceding three months were recruited. Measurements were performed during two sessions (three to seven days between sessions) by three clinicians. FABER height and thigh length measurements were performed. Thigh length normalized FABER range of motion (ROM) and side-to-side FABER ROM symmetry were calculated. One tester also measured FABER with a digital inclinometer. Inter- and intra-rater reliability were calculated using interclass correlation coefficients (ICC) and mean MDC values were calculated.
Mean values for FABER height and normalized FABER ROM were 12.4 ± 2.8 cm and 0.30 ± 0.07, respectively. Inter-rater reliability for FABER and normalized FABER were good (ICC 0.67-0.68) and between session intra-rater reliability were good to excellent (ICC 0.76-0.86). Mean FABER and normalized FABER ROM MDC were 3.7 cm and 0.04, respectively. Mean FABER ROM symmetry was 2.0 ± 0.9 cm with poor inter-rater reliability (ICC 0.20), poor to good intra-rater reliability (ICC 0.38-0.66), and mean MDC of 4.0 cm. FABER measured with a ruler, normalized FABER ROM, and inclinometry all resulted in excellent intra-rater reliability, with the highest ICC being demonstrated for inclinometry (ICC 0.86, 0.86, and 0.91).
Overall, FABER measurements were reliable, whether normalized to thigh length or not. Furthermore, use of inclinometry may increase reliability. Reliability was poor to good when assessing symmetry between limbs.
Level 3.
屈曲外展外旋（FABER）试验通常用作激发性特殊试验，但也被用作髋关节活动范围（ROM）综合测量。人们认为，这种测量中ROM受限可能提示髋关节病变。迄今为止，此类测量的规范数据、可靠性和最小可检测变化（MDC）尚未确定。
确定FABER高度的规范值，评估FABER试验的评分者间和评分者内可靠性以及MDC，并将传统FABER测量方法与考虑大腿长度差异的方法进行比较。
描述性实验室可靠性研究。
招募了19名在过去三个月内无腰、髋或膝关节疼痛的健康参与者。由三名临床医生在两个阶段（阶段间间隔三至七天）进行测量。进行FABER高度和大腿长度测量。计算大腿长度标准化的FABER活动范围（ROM）和双侧FABER ROM对称性。一名测试者还使用数字倾角仪测量FABER。使用组内相关系数（ICC）计算评分者间和评分者内可靠性，并计算平均MDC值。
FABER高度和标准化FABER ROM的平均值分别为12.4±2.8厘米和0.30±0.07。FABER和标准化FABER的评分者间可靠性良好（ICC 0.67 - 0.68），阶段间评分者内可靠性良好至优秀（ICC 0.76 - 0.86）。FABER和标准化FABER ROM的平均MDC分别为3.7厘米和0.04。FABER ROM对称性的平均值为2.0±0.9厘米，评分者间可靠性较差（ICC 0.20），评分者内可靠性从差到良好（ICC 0.38 - 0.66），平均MDC为4.0厘米。用尺子测量的FABER、标准化FABER ROM和倾角测量法均具有出色的评分者内可靠性，其中倾角测量法的ICC最高（ICC 0.86、0.86和0.91）。
总体而言，无论是否根据大腿长度进行标准化，FABER测量都是可靠的。此外，使用倾角测量法可能会提高可靠性。评估肢体间对称性时，可靠性从差到良好。
