ABSTRACT

PURPOSE: This study investigated the effects of robot-assisted gait training (RAGT) combined with rhythmic auditory stimulation (RAS) on the balance, gait, and activities of daily living (ADL) in patients with chronic stroke. METHODS: Forty-eight patients with chronic stroke were assigned randomly to an experimental group (RAGT with RAS, n = 24) or a control group (RAGT only, n = 24). Both groups received 30-minute sessions, five times per week for four weeks, along with conventional physical therapy. The outcome measures included the Berg Balance Scale (BBS), Functional Reach Test (FRT), Timed Up and Go test (TUG), 10-Meter Walk Test (10MWT), six-Minute Walk Test (6MWT), and Korean Modified Barthel Index (K-MBI). Statistical analyses were performed using the Wilcoxon signed-rank and Mann-Whitney U tests with significance at p < .05. RESULTS: Both groups showed significant within-group improvements in all outcome measures after the intervention (p < .05). Between-group comparisons showed that the experimental group had significantly greater improvements in TUG (p = .007) and 10MWT (p = .014) than the control group. No significant between-group differences in BBS, FRT, 6MWT, or K-MBI were found. CONCLUSION: RAGT combined with RAS effectively improves the gait speed and functional mobility in chronic stroke patients. The addition of RAS to RAGT provides significant benefits for temporal gait parameters and dynamic mobility, offering a practical and cost-effective adjunct to robotic gait rehabilitation. Nevertheless, no additional benefits were observed for the static balance or ADL performance, suggesting that longer intervention periods or targeted outcome measures may be needed to detect broader functional improvements.
