Objective: The purpose of this study was to investigate the effects of intensive gait training with body weight support treadmill training on gait and balance in stroke disability patients. Design: Randomized controlled trial. Methods: Twenty-six stroke patients (20 men and 6 women) participated in this study. All subjects were hospitalized patients. They were randomly divided into two groups: the experimental group (body weight supported treadmill training group, n=14) and control group (treadmill group, n=12). The mean ages were 52.07 years (experimental group) and 53.83 years (control group). Subjects in both groups received conventional training 10 times/wk. Subjects in the experimental group practiced body weight supported treadmill training for 30 minutes a day, 3 day/wk. Subjects in the control group practiced treadmill training for 30 minutes. The Berg Balance Scale (BBS) and GAITRite were used to evaluate balance and gait parameters (step length, cadence and gait speed) before and after the intervention. Results: BBS scores in the experimental group showed significantly greater improvement (4.33±1.54), compared with the control group (p<0.05). Significantly greater improvement in the gait speed (24.13±4.53 cm/s), affected side step length (10.40±3.42cm), sound side step length (11.97±3.29 cm), and cadence (23.88±5.52 step/min), compared with the control group (p<0.05). Conclusions: Intensive gait training with Body Weight Support Treadmill Training may improve gait and balance in subacute stroke.
