Hip strength assessment plays an important role in the clinical examination of the hip and groin region. The primary aim of this study was to examine the absolute test-retest measurement variation concerning standardized strength assessments of hip abduction (ABD), adduction (ADD), external rotation (ER), internal rotation (IR), flexion (FLEX) and extension (EXT) using a hand-held dynamometer. Nine subjects (five males, four females), physically active for at least 2.5 h a week, were included. Twelve standardized isometric strength tests were performed twice with a 1-week interval in between by the same examiner. The test order was randomized to avoid systematic bias. Measurement variation between sessions was 3-12%. When the maximum value of four measurements was used, test-retest measurement variation was below 10% in 11 of the 12 individual hip strength tests and below 5% in five of the 12 tests. No systematic differences were present. Standardized strength assessment procedures of hip ABD, ER, IR, FLEX, with test-retest measurement variation below 5%, hip ADD below 6% and hip EXT below 8%, make it possible to determine even small changes in hip strength at the individual level.
髋关节力量评估在髋关节和腹股沟区域的临床检查中起着重要作用。本研究的主要目的是使用手持测力计检查髋关节外展（ABD）、内收（ADD）、外旋（ER）、内旋（IR）、屈曲（FLEX）和伸展（EXT）的标准化力量评估的绝对测试-重测测量变化。共纳入 9 名受试者（5 名男性，4 名女性），每周至少进行 2.5 小时的体育活动。进行了 12 次标准化等长力量测试，两次测试之间间隔 1 周，由同一位检查者进行。测试顺序随机化以避免系统偏差。两次测试之间的测量变化为 3-12%。当使用四个测量值中的最大值时，在 12 项个体髋关节力量测试中的 11 项中，重测测量变化低于 10%，在 12 项测试中的 5 项中，重测测量变化低于 5%。没有出现系统差异。髋关节 ABD、ER、IR、FLEX 的标准化力量评估程序，重测测量变化低于 5%，髋关节 ADD 低于 6%，髋关节 EXT 低于 8%，使得能够确定个体水平上髋关节力量的微小变化。
