To evaluate the effect of the biofeedback balance training using Interactive Balance System (IBS) in acute stroke patients.
We recruited 40 acute stroke patients who were able to stand independently. The patients were divided into two groups. One group received conventional balance training (control group) and the other group received biofeedback balance training using IBS (case group) for 2 weeks. After training, the effects were evaluated using 3 parameters: indices from IBS (stability score, weight distribution index, and distance form zero point to body's center of pressure (COP) in coordinate), balance assessments (Berg balance scale and postural assessment scale for stroke patients), and functional outcome (the Korean version of modified Barthel index).
There were no differences in age and time since onset between the two groups. All parameters were significantly improved in both groups after training. However, the distribution of COP of the case group was significantly closer to the zero point than that of the control group in coordinate after training (p=0.005).
Biofeedback balance training using IBS has a better effect on the symmetry in static condition on evaluation using IBS than conventional balance training for acute stroke patients. (J Korean Acad Rehab Med 2009; 33: 41-47)
