Purpose : This study aimed to identify whether resistance exercise using elastic bands for six weeks can improve muscle strength, muscle tone, balance, and gait in patients with stroke.
Methods : In total, 35 patients with stroke were randomly divided into three groups: resistance exercise using elastic band training combined with less affected side training group, more affected side training group, and both sides training group. Muscle strength, muscle tone, balance, and gait were assessed using a hand-held dynamometer, the modified Ashworth scale, the Berg Balance scale (BBS), and wireless 3-axis accelerometer, before and after training.
Results : All three groups showed a significant increase in muscle strength of the lower extremity after training, and there was a significant difference among the groups. There was no change in muscle tone in all three groups. BBS scores increased significantly in all three groups after training, but these scores were not significantly different. The gait speed increased significantly in all three groups after the training, but the difference was not significant. The cadence increased significantly in Group 2 after training; however, there was no significant difference between Groups 1 and 3. There were no significant differences between the groups before and after the training. Step length increased significantly in Groups 2 and 3 after the training, but it was not significantly different in Group 1. After training, Groups 2 and 3 were significantly greater than Group 1 in the change in step length.
Conclusion : The results show that resistance exercise using elastic bands can improve strength, balance, and gait in patients with chronic stroke. Especially, more affected side training was more effective in improving muscle strength than less affected side training. More affected side and both sides training are thought to be more effective than less affected side training to improve step length.
