The purposes of this study were to explore reliability of the ulnar F-wave minimum latency (Fmin) and the ulnar distal motor latency (DML) and to contrast those levels of reliability in order to reveal whether physiologic lability is the primary contributor to unwanted variability in Fmin measurements.
Fmin and DML in the Abductor Digiti Minimi muscle were measured bilaterally by two raters in 50 healthy adults (n = 100 hands, 70 male, 30 female) with 3-14 days between testing sessions.
Intrarater reliability (ICC 3,1) for the Fmin was 0.89 with a standard error of the measurement (SEM) of 0.77 msec. Interrater reliability (ICC 2,1) for the Fmin was 0.80 with a SEM of 1.04 msec. Intrarater reliability (ICC 3,1) for the DML was 0.71 with a SEM of 0.18 msec. Interrater reliability (ICC 2,1) for the DML was 0.76 with a SEM of 0.19 msec.
Contrary to our hypothesis, the Fmin had a higher reliability than the DML. The DML did not display the high reliability other investigators have reported. We conclude the Fmin is a reliable measurement when 10 supramaximal stimulations are administered to healthy, young to middle-aged adult subjects. However, no inferences were made regarding relative levels of psychologic lability for the two latencies.
本研究旨在探讨尺神经F波最小潜伏期（Fmin）和尺神经远端运动潜伏期（DML）的可靠性，并对比这些可靠性水平，以揭示生理易变性是否是Fmin测量中不必要变异的主要因素。
由两名评估者对50名健康成年人（n = 100只手，70名男性，30名女性）双侧小指展肌的Fmin和DML进行测量，两次测试之间间隔3 - 14天。
Fmin的评估者内可靠性（ICC 3,1）为0.89，测量标准误（SEM）为0.77毫秒。Fmin的评估者间可靠性（ICC 2,1）为0.80，SEM为1.04毫秒。DML的评估者内可靠性（ICC 3,1）为0.71，SEM为0.18毫秒。DML的评估者间可靠性（ICC 2,1）为0.76，SEM为0.19毫秒。
与我们的假设相反，Fmin的可靠性高于DML。DML并未表现出其他研究者所报告的高可靠性。我们得出结论，当对健康的年轻至中年成年受试者进行10次超强刺激时，Fmin是一项可靠的测量指标。然而，未对两种潜伏期的心理易变性相对水平进行推断。
