The purpose of this study was to determine the test-retest reliability and precision of Rotterdam Intrinsic Hand Myometer (RIHM) in healthy adults.
Twenty-nine participants originally recruited via convenience sampling at a Midwestern state fair returned approximately 8 days later for retest. An average of three trials for each of the five intrinsic hand strength measurements were collected using the same technique that was used during initial testing. Test-retest reliability was assessed using the intraclass correlation coefficient or ICC and precision was evaluated using the standard error of measurement (SEM), and the minimal detectable change (MDC)/MDC%.
Across all measures of intrinsic strength, the RIHM and its standardized procedures had excellent test-retest reliability. Index finger metacarpophalangeal flexion demonstrated the lowest reliability, and right small finger abduction, left thumb carpometacarpal abduction, and index finger metacarpophalangeal abduction tests had the highest reliability. Precision, as evidenced by SEM and MDC values, was excellent for tests of left index and bilateral small finger abduction strength and acceptable for all other measurements.
Test-retest reliability and precision of RIHM across all measurements was excellent.
These findings indicate that RIHM is a reliable and precise tool in measuring intrinsic strength of hands of healthy adults, although further research is needed in clinical populations.
本研究旨在确定健康成年人使用 Rotterdam 内在手部测力计（RIHM）的重测信度和精密度。
最初通过在中西部州博览会上进行方便抽样招募的 29 名参与者在大约 8 天后返回进行复测。使用与初始测试相同的技术，对五个内在手部力量测量中的每一个进行平均三次测试。使用组内相关系数（ICC）评估重测信度，使用测量标准差（SEM）和最小可检测变化（MDC）/MDC%评估精密度。
在所有内在力量测量中，RIHM 及其标准化程序具有出色的重测信度。食指掌指关节屈曲的可靠性最低，而右手小指外展、左手拇指腕掌关节外展和食指掌指关节外展测试的可靠性最高。SEM 和 MDC 值表明，左手食指和双侧小指外展力量测试的精密度非常好，而所有其他测量的精密度则可以接受。
RIHM 在所有测量中的重测信度和精密度均非常出色。
这些发现表明，RIHM 是一种可靠且精确的工具，可用于测量健康成年人手部的内在力量，但在临床人群中还需要进一步研究。
