Abstract

The purpose of this study was to evaluate the effect of dual-task training with cognitive effort on the walking and balance functions of chronic stroke patients. The study included 14 chronic stroke patients, who were randomly divided into the experimental group (EG) and control group (CG), each with 7 patients. The EG performed the dual-task training with cognitive effort 3 times a week, 30 minutes for 4 weeks, where as the CG performed single-task training three times a week, for 30 minutes for 4 weeks. Outcome assessments were made with 10 m walk test, timed up and go test, 6 minutes walk test, and Berg balance scale. In within-group comparison, subjects from the EG showed significant differences in all variables (p<.05), while subjects from the CG showed only significant differences in 6 minutes walk test, and Berg balance scale (p<.05). Further, there was significant difference in the improvement rate of 10 m walk test. The findings suggest that the dual-task with cognitive effort may be beneficial for improving walking and balance functions of patients with chronic stroke.
