The purpose of this study was to determine the effects of augmented reality (AR)-based postural control training on balance and gait function in stroke patients. Twenty-one stroke patients were assigned to either an experimental group (n = 10) or a control group (n = 11). Patients in both groups received a general physical therapy program for a duration of 30 minutes per session, 5 days per week, for a period of 4 weeks. Participants in the experimental group received additional AR-based postural control training for 30 minutes per day, 3 days per week, for a period of 4 weeks. Patients were assessed with the timed up-and-go test, Berg Balance Scale test, and spatiotemporal parameters using the GAITRite system. Results of repeated-measures analysis of covariance showed a significant main effect of time on timed up-and-go test, Berg Balance Scale, velocity, cadence, step length and stride length of paretic and nonparetic sides. In addition, walking velocity, step length, and stride length on both the paretic and nonparetic sides showed a significant group x time interaction effect. The results of this study provide evidence in support of incorporating an AR environment into postural control training for improving gait of stroke patients.
