Spatio-temporal parameters during steady walking. Spatio-temporal parameters (mean ± standard deviation) observed during steady walking trials, before (baseline) and after (post-) training, for subjects with cerebellar ataxia (CA; gray bars) and healthy control group (HG; black bars). Pairwise comparisons reaching significance are reported (* p < 0.05, ** p < 0.01, *** p < 0.0001); vertical and horizontal lines are related to the group (CA vs HG) and session (pre vs post) effects, respectively. a step length; b step width; c step duration; d stance%
