Temporal-spatial ICC and MDC values during unperturbed and perturbed walking.

Walking conditions are labeled as NOP–no perturbation, COG–cognitive perturbation, PLAT–physical perturbation, and VIS–visual perturbation. Bold values exhibited excellent between-session reliability (ICC ≥ 0.75).
Temporal-spatial ICC and MDC values during unperturbed and perturbed walking.

行走工况被标记为四类：NOP（无扰动，no perturbation）、COG（认知扰动，cognitive perturbation）、PLAT（物理扰动，physical perturbation）以及VIS（视觉扰动，visual perturbation）。其中加粗数值展现出优异的组间信度，组内相关系数（Intraclass Correlation Coefficient, ICC）≥0.75。无扰动及扰动行走工况下的时空参数组内相关系数与最小可检测变化（Minimum Detectable Change, MDC）数值。
