| dc.title | Effectiveness of biofeedback on improving stance symmetry in stroke rehabilitation | en_US |
| dcterms.abstract | The purposes of this study are to assess the effectiveness of a clinically practical visual and auditory biofeedback training protocol provided by the Balance Performance Monitor on improving stance symmetry, postural sway, balance function and independence in activities of daily living in stroke rehabilitation; and to suggest the protocol to the physiotherapy field for the management of stroke patients if it is proven to be effective. 20 first stroke patients were conveniently recruited and randomly assigned into the biofeedback training group and the conventional treatment group with 10 subjects in each group. The biofeedback training group received 6 sessions of 15 minutes biofeedback training in two weeks on top of the conventional treatment provided by the clinical management team while the conventional treatment group received the conventional treatment only. Pre-test and post-test on stance symmetry, postural sway, balance function and independence in activities of daily living were measured using the Balance number and the Sway number generated from the Balance Performance Monitor, the Berg's balance scale (Berg et al., 1995) and the Barthel index (Granger et al., 1979) respectively. Mann-Whitney U test was used to test for the differences of mean of all the respective values between the two groups. Wilcoxon Matched-Pairs Signed-Ranks test was used to test the differences of mean between all the pre and post paired values within the same group. Results suggest that there are significant improvement in stance symmetry (p=0.0069), postural sway (p=0.0125), balance function (p=0.0051), independence in activities of daily living (p=0.0051) in the biofeedback training group. For the conventional treatment group, there are significant improvement in balance function (p=0.0077) and independence in activities of daily living (p=0.018) but not in stance symmetry (p=0.2845) and postural sway (p=0.2845). The balance function and independence in activities of daily living in the biofeedback training group are not outstanding when compared to that of the conventional treatment group. It can be concluded that visual and auditory biofeedback provided by the Balance Performance Monitor can effectively improve stance symmetry and postural sway in stroke patients. Therefore, it is strongly recommended that physiotherapists may use biofeedback as an adjunct in stroke rehabilitation to improve stroke patients' stance symmetry and postural sway. However, the transfer of improvement in stance symmetry to balance function and independence in activities of daily living remains questionable. Further researches are recommended to identify the effectiveness of lateral transfer of improvement in stance symmetry to balance function and independence in activities of daily living in stroke rehabilitation. | en_US |
