|
Purpose: This study was conducted in order to investigate the effectiveness of an 8-week virtual reality exercise program designed around the Nintendo Wii (Wii), in improving balance among patients with Multiple Sclerosis (MS).
Methods: The study included 16 patients with MS (10 female, 6 male) who were assigned randomly to experimental (n=8) or control group (n=8). Experimental group performed three 40-minute Wii balance-training sessions per week, for 8 weeks. The control group did not perform any of the training programs. A computerized dynamic posturography (Sensory Organizing Test, SOT) was used to evaluate all patients at baseline and at the end of the treatment protocol. Statistical significance was tested in between the patients before and after treatment by t-test.
Results: After 24 training sessions, SOT showed significant difference on condition 5, 6, and vestibular ratios within the experimental group from baseline to post-intervention. By contrast, no significant difference was observed within the control groups.
Conclusion: These findings demonstrated that the virtual reality training program could improve the outcomes in terms of balance in the MS population. Long term follow ups and the development of more efficient virtual reality training programs are needed.
