Purpose:This study was conducted to compare the effect of visual feedback training using mirror and the training without mirror on the balance in people with hemiplegic paralysis.
Methods:A total of 26 stroke patients were enrolled in this study. The participants were allocated randomly to 2 groups : visual feedback training group(n=13) and control group(n=13). Both groups received PNF(proprioceptive neuromuscular facilitation) for 5 times(each 30 minutes) per week over 6 weeks period. The group, which is enrolled in visual feed back training, performed additional exercise in front of mirror for 30 minutes. The control group performed same exercise without mirror. The data was analyzed using a paired t-test and independent t-test to determine the statistical significance.
Results:The visual feedback training group showed significantly increased foot pressure and total pressure compared to the control group(p<.05) and significantly decreased body sway compared to the control group (p<.05). Also, visual feedback training group showed significant increase on the Berg Balance Scale(BBS), Timed Up and Go test(TUG) compared to the control group(p<.05).
Conclusion:These results support the perceived benefits of visual feedback training using mirror to augment the balance of stroke patients. Therefore, visual feedback training using mirror is feasible and suitable for stroke patients.
