计算机化步态评估通常用于研究和临床环境中，以量化步态力学并检测性能变化。最小可检测变化值最近才被报道，仅适用于患者人群，在许多情况下超过10度。29名健康个体接受了两次生物力学步态评估，间隔5.6（SD 2.2）天，每次有两名评估者。所有受试者以自选的步速和三种受控速度行走。国际刑事法院运动学和动力学指标的SEM和MDC计算为interrater-intrasession，intrarater-intersession和interrater-intersession。对于所有运动学和动力学变量以及所有比较，ICC值均在良好至极佳范围内（r > 0.75）。MDC值低于先前发表的所有类似比较的数据。当前研究的结果表明，在一系列受控步行速度范围内，可靠性为良好至优秀，引入第二名评分者不会明显影响ICC或MDC值。在年轻健康的成年人中，当在会话之间进行比较时，可以确定大于约50的步态运动学变化。由爱思唯尔公司出版
Computerized assessment of gait is commonly used in both research and clinical settings to quantify gait mechanics and detect change in performance. Minimal Detectable Change values have only recently been reported, are only available for patient populations, and in many cases exceed 10 degrees. Twenty nine healthy individuals underwent two biomechanical gait assessments separated by 5.6 (SD 2.2) days, with two raters for each session. All subjects walked at a self selected pace and three controlled velocities. ICC. SEM and MDC for kinematic and kinetic measures were calculated for interrater-intrasession, intrarater-intersession and interrater-intersession. ICC values were in the good to excellent range (r > 0.75) for all kinematic and kinetic variables and all comparisons. M DC values were lower than previously published data for all similar comparisons. The results of the current study suggest that reliability is good to excellent across a range of controlled walking velocities and the introduction of a second rater does not appreciably impact ICC or MDC values. In young healthy adults changes in gait kinematics of greater than approximately 50 can be identified when comparing between sessions. Published by Elsevier B.V.
