概要	This study aimed to examine the characteristics of patients with ataxia after stroke based on their motor function to identify variables associated with fall occurrence. We divided 33 participants who presented with ataxia after stroke into fall and non-fall groups. Data on motor function, cognitive function, and daily functionality were extracted from their admission records. Walking ability was measured as comfortable walking speed and Stride Time Variability (STV). In the multiple logistic regression analysis, only STV was associated ith an increased risk of falls (p < .02). The area under the receiver operating characteristic curve was 0.839; the cutoff value of gait cycle variability for falls was 6.345% (sensitivity, 80.0%; specificity, 74.0%). Increased stride time variability is a useful indicator that sensitively captures fall risk in patients with ataxia after stroke.
