Retraining impaired gait is essential in post-stroke recovery. This project aims to determine between day variability of spatiotemporal gait measures in treadmill walking post-stroke to differentiate between changes due to the intervention and measurement errors due to between day test-retest variability. Six individuals post-stroke performed a two-minute walk test at a self-selected speed (SSS) for two consecutive days. SSS was assessed through the six-minute walk test. Reflective markers were placed on anatomical landmarks (van den Bogert et al. 2013). The heel markers were used for step detection. We calculated spatiotemporal parameters: stride length, stride time, step length, stance time, and swing time for both paretic and nonparetic legs. We calculated the test-re-test intra-class correlation coefficient (ICC) using a 2,1 model (Shrout, Fleiss 1979) the minimal detectable change (MDC). We list the correlation coefficients, ICC, and MDC values for each spatiotemporal variable. Stride length: r=0.995, p
