PURPOSE: This study compared the effectiveness of trunk control exercise performed on an unstable surface with that of general balance exercise on dynamic balance in the patients with chronic stroke. METHODS: The persons of this study were thirty-seven chronic stroke patients were recruited and randomly divided into 2 groups; (1) those who performed trunk control exercise on a foam roll and (2) those who performed general balance exercise. The exercises were performed 5 times a week for 4 weeks. To determine the effectiveness of the 2 types of exercises, we measured dynamic balance at the beginning of the exercises and again after 4 weeks at the completion of exercises program. RESULTS: After 4 weeks of exercise, both the groups showed increased Berg's balance scale and timed-up-and-go test (p<.001) scores. However, Trunk control exercise group was more effective than general balance exercise group was in increasing the Berg's balance scale (p<.01) and timed-up-and-go test (p<.05) scores. CONCLUSION: We suggest that trunk control exercise may be effective in increasing the balance ability of patients with chronic stroke than general balance exercise. Thus, trunk control exercise is important for such patients. Further studies are needed for better understanding of the effectiveness of trunk control exercise in chronic stroke patients.
