[目的]本研究的目的是通过对两种不同设计的手持式测力仪（hhd - 1,2）分别进行两次等距膝关节肌肉伸展测量，来比较其可靠性。【研究对象】40名年轻健康成人。[方法]采用Bland-Altman分析对测量结果进行信度检验。[结果]Bland-Altman分析发现HHD-1测量的固定偏差平均一致限（LOA）值为−2.1 kgf。对于HHD-2，只检测到随机误差，最小可检测变化（MDC）为11.4 kgf。在两个器件之间观察到固定偏差，平均LOA值为2.2 kgf。当使用体重比时，两种装置的测量结果存在固定偏差，LOA平均值为- 0.03 kgf/kg。两种装置的比较仅显示随机误差，MDC为0.22 kgf/kg。【结论】使用这两种仪器测量HHD时，测量次数以2次为宜，避免两种仪器测量值的比较。
[Purpose] The purpose of the present study was to compare the reliability of 2 hand-held dynamometers (HHD-1, 2) with different designs, by performing isometric knee muscle extension measurements two times each. [Subjects] The subjects were 40 young healthy adults. [Methods] The reliability of the measurements was examined using Bland-Altman analysis. [Results] Bland-Altman analysis found a fixed bias in measurements made by HHD-1 with an average limits of agreement (LOA) value of −2.1 kgf. For HHD-2, only random errors were detected, and the minimal detectable change (MDC) was 11.4 kgf. Fixed biases were observed between the two devices with an average LOA value of 2.2 kgf. When the bodyweight ratio was used, fixed biases were observed in measurements made by both devices, and the average value of LOA was −0.03 kgf/kg. The comparison of the two devices revealed only random errors, and MDC was 0.22 kgf/kg. [Conclusion] For HHD measurements using these two devices, the appropriate number of measurements is two times, and comparison of measurement values between the two devices should be avoided.
