Abstract
Purpose: This study investigated the effects of trunk exercise using less-affected extremities on gait and balance in chronic stroke patients.
Methods: Thirty subjects with chronic stroke disease were divided into two groups: a trunk exercise group that used less-affected extremities (n=15) and a general trunk exercise group (n=15). All interventions were conducted 30 min a day, 6 times per week, for 3 weeks. Gait parameters were measured before and after the intervention using Zebris FDM-1.5. In addition, all subjects were evaluated using the Trunk Impairment Scale, the Berg Balance Scale, and the Functional Gait Assessment before and after the intervention.
Results: Both groups showed improvements on all outcome measured pre- to post-intervention (p<0.05). The groups exhibited significant differences for TIS, BBS, FGA, gait speed, step length, and cadence at post-intervention (p<0.05).
Conclusion: This study showed that trunk exercise using less-affected extremities has therapeutic benefits on gait and balance in individuals with chronic stroke disease.
