OBJECTIVE: This study compared the effects of virtual reality (VR)-assisted gait adaptation training with the overground gait adaptation training on balance and walking in patients with stroke. METHODS: Fifty-four eligible patients were enrolled. All patients were randomly divided into a VR and control group, with 27 patients in each group. The VR group received VR-assisted training on the treadmill, whereas the control group received overground training in a physical therapy room. After the intervention, patients were assessed using walking speed, obstacle avoidance ability, timed up and go (TUG) test, postural stability, and the Barthel Index (BI). RESULTS: Significant improvements in walking speed, obstacle avoidance ability, TUG test and eye-opening center of pressure (COP) speed were observed after the intervention (p < 0.05). No statistically significant differences were found in eye-closing COP speed, tandem COP speed, single-leg COP speed, and BI (p > 0.05). CONCLUSIONS: Stroke patients may benefit from VR-assisted gait adaptation training in improving walking and static balance function and reducing the risk of falls.
