Three-Dimensional Balance Training Using Visual Feedback on Balance and Walking Ability in Subacute Stroke Patients: A Single-Blinded Randomized Controlled Pilot Trial.

BACKGROUND: Trunk-activating exercises for balance are important because trunk weakness is relevant to the functional performance of individuals with stroke. This study aimed to explore the effects of three-dimensional balance training using visual feedback on balance and walking ability in subacute stroke patients. METHODS: Twenty-four participants with subacute stroke were randomly assigned to the experimental or control group. Each group underwent twenty sessions (30 min/day, 5 days/week for 4 weeks). Patients were assessed using the Berg balance scale, gait parameters (gait speed, cadence, step length, and double-limb support period) using GAITRite, and activity-specific balance confidence score, before and after the intervention. RESULTS: The three-dimensional balance training using visual feedback exhibited greater changes in the Berg balance scale, gait speed, cadence, step length, double-limb support period, and activity-specific balance confidence compared with the control group. Statistical analyses showed significant differences in Berg balance scale (P = .012; 95% CI, 2.585-6.415), gait speed (P = .001; 95% CI, .079-.155), cadence (P = .001; 95% CI, 1.622-4.392), step length (P = .003; 95% CI, 1.864-3.908), double-limb support period (P = .003; 95% CI, -3.259 to -0.761) and activity-specific confidence (P = .008; 95% CI, 6.964-14.036) between groups. CONCLUSION: Three-dimensional balance training using visual feedback may be more effective than conventional training in improving balance, walking ability, and activity-specific balance confidence in patients with subacute stroke.

Gait Training with Bilateral Rhythmic Auditory Stimulation in Stroke Patients: A Randomized Controlled Trial.

The aim of this study was to investigate the effect of gait training with bilateral rhythmic auditory stimulation (RAS) on lower extremity rehabilitation in stroke patients. Forty-four participants (<6 months after stroke) were randomly allocated to the gait training with bilateral rhythmic auditory stimulation (GTBR) group (n = 23) and the control group (n = 21). The GTBR group had gait training with bilateral RAS for 30 min a day, 5 days a week, in a 6-week period, in addition to conventional therapy. The control group had gait training without RAS, and conventional therapy. Outcome measures included gait symmetry, gait ability, balance ability, and lower extremity function. Gait symmetry on step time showed significant improvements compared to baseline (p < 0.05) in the GTBR group, but not in the control group. Gait ability was significantly improved in both groups relative to baseline values (p < 0.05), and the GTBR group showed significantly greater improvement in comparison to the control group (p < 0.05). Both groups showed significant improvements in the Timed Up and Go test (TUG), Berg Balance Scale (BBS), and Fugl⁻Meyer Assessment (FMA) compared to baseline (p < 0.05). GTBR is an effective therapeutic method of improving symmetric gait in stroke rehabilitation. Moreover, we found that GTBR beat frequency matching fast step time might be even more beneficial in improving gait symmetry. Future studies may develop a method of applying RAS on step time and length for improvement of gait symmetry in stroke patients.
