This study compared the effects of unstable-surface gait training (UGT) and stable-surface gait training (SGT) on gait function, balance ability, and lower extremity strength in patients with subacute stroke. Twenty-four participants (1–6 months post-stroke) were randomly assigned to the UGT group (n = 12) or the SGT group (n = 12). Both groups performed supervised gait training for 30 minutes per session, five times per week, for four weeks. Gait function was assessed using the 10-meter walk test, balance ability using the Berg Balance Scale and postural stability measures, and lower extremity function using the five-times sit-to-stand test and isokinetic strength testing. After the intervention, both groups showed significant improvements; however, the UGT group demonstrated significantly greater improvements in gait speed, balance performance, fall risk, and knee extension strength compared with the SGT group (p < 0.05). These results indicate that unstable-surface gait training is more effective than stable-surface gait training for improving gait function, balance ability, and lower extremity strength in patients with subacute stroke.
