The Effects of Robot-Assisted Gait Training with Visual Feedback on Gait, Balance and Balance Confidence in Chronic Stroke Patients

Abstract

Purpose: This study was conducted to assess the effects of robot-assisted gait training with visual feedback on gait, balance, and balance confidence in patients with chronic stroke. Methods: Thirty subjects with chronic stroke were randomly assigned to two groups: the experimental group (n= 15) and the control group (n = 15). The experimental group performed robot-assisted gait training for 30 minutes and the control group performed gait training with assisted devices training for 30 minutes after both groups performed conventional physical therapy for 30 minutes. Both groups performed the therapeutic interventions for 5 days per week, for a period of 4 weeks. For assessment of the 10 m walking test (10 MWT), Figure of 8 on the walk test (F8WT), Timed-Up and Go test (TUG), and Berg Balance Scale (BBS) were used to test the gait and balance, and the Korean version of the Activities-specific Balance Confidence Scale was used to test the balance confidence. Results: The experimental group showed significant improvement in the 10 MWT and the K-ABC (p < 0.05), and the control group showed significant improvement in the BBS and the TUG (p< 0.05). In four measurements, there were significant differences between the two groups (p< 0.05), and the control group showed significant improvement in the F8WT at pre and post intervention (p< 0.05).
