This study determined the reliability of muscle function and sensory perception measures of the wrist extensors. The test-retest reliability of the measurements was determined by an intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of measurements (SEMs), and one-way repeated measures ANOVA using the values collected from 25 young (20.6 +/- 1.3 years) healthy male volunteers on two occasions separated by 1 day. The measures consisted of grip strength, wrist extension strength (WES), range of motion in active and passive wrist flexion and extension, choice reaction time (CRT), vibration sense (VIB), joint position error sense (JPE), cold pain (CP) and heat pain threshold, and pressure pain threshold. An acceptable reliability was determined as the ICC values greater than 0.85, CV less than 15%, and SEMs less than 5%. ICC of all measures except for JPE were greater than 0.85, only CV of JPE, CP, and VIB exceeded 15%, SEMs were higher than 5% only for JPE and CP, and the ANOVA showed a significant time effect for CRT and WES. It is concluded that most of the measurements except JPE are reliable and can be used to investigate effects of a physiotherapy intervention on the wrist extensors.
本研究旨在确定腕伸肌的肌肉功能和感觉知觉测量的可靠性。通过使用 25 名年轻（20.6 +/- 1.3 岁）健康男性志愿者在两天内收集的值，采用组内相关系数（ICC）、变异系数（CV）、测量标准误差（SEMs）和单向重复测量方差分析来确定测量的测试-重测可靠性。这些测量包括握力、腕伸肌力量（WES）、主动和被动腕屈和伸的活动范围、选择反应时间（CRT）、振动感觉（VIB）、关节位置误差感觉（JPE）、冷痛（CP）和热痛阈值以及压痛阈值。可接受的可靠性确定为 ICC 值大于 0.85、CV 小于 15% 和 SEMs 小于 5%。除 JPE 外，所有测量的 ICC 均大于 0.85，仅 JPE、CP 和 VIB 的 CV 超过 15%，仅 JPE 和 CP 的 SEMs 高于 5%，方差分析显示 CRT 和 WES 存在显著的时间效应。因此，除 JPE 外，大多数测量结果都是可靠的，可以用于研究物理治疗干预对腕伸肌的影响。
