Purpose: The purpose of this study was to identify whether resistance exercise using elastic band for 6 weeks could improve the muscle strength, muscle tone, balance and gait in stroke patients.
Method: Eleven stroke patients who had agreed with the study were randomly divided into 3 groups categorized as resistance exercise using elastic band training combined with less affected side training group (experimental group 1, n=4), affected side training group (experimental group 2, n=3), and both side training group(experimental group 3, n=4). The muscle strength, muscle tone, balance and gait were assessed by hand-held dynamometer, Modified Ashworth Scale (MAS), Berg Balance Scale and G-walk at before training and after training. Wilcoxon signed rank test was used to analyze change before and after intervention in intra-group. Kruskal Wallis H test, Mann-Whitney U test were used to analyze changes of all variables in inter-groups.
Result: All the muscle strength except the affected knee flexor and extensor muscle were increased in all three groups but no significant difference. There was no change in muscle tone(MAS) in all three groups. All three groups showed an increase in BBS scores but no significant difference. Walking speed and walking symmetry were increased in all groups but there was no significant difference following training. The changes of affected step length in the experimental group 1 were significantly greater than them of the experimental group 3. The changes of affected step length in the experimental group 3 were significantly greater than them of the experimental group 2.
Conclusion: The result of this study suggest the resistance exercise using elastic would be a potential intervention to
improve muscle strength of lower extremities, balance and gait in stoke patients.
