Selected results from the comparison across pre-training, post-training, and follow-up visits. Clinical measures: timed up and go (A), dynamic gait index (B). Static balance measure: sway amplitude for eyes closed condition (average of all subjects except #9, 11, 12, 13, who were unable to perform the task) (C). Walking parameters: walking speed (D), stride length (E), double support time percent (F). Average values ± 1 standard error indicated for all measures; asterisks indicate post-hoc comparison for measures with significant differences (p<0.05).
