Abstract


Purpose : The purpose of this study is to find out if it helps to improve static balance ability and weight bearing rate for chronic stroke patients with poor balance in clinical intervention through a method of correcting movement errors while performing a task by tactile bio-feedback providing pressure information.

Methods : Fifteen chronic stroke patients (12 men and 3 women) participated in this study. To examine the effects of tactile bio-feedback and general standing without bio-feedback on static balance ability and weight distribution symmetric index in all subjects randomized with R Studio. The static balance ability and weight distribution symmetric index of the participants was evaluated using a Wii balance board and the Balancia program. A paired t-test was used for comparison of each conditions. Statistical significance was set at α=0.05.

Results : The comparisons of static balance ability and weight distribution symmetric index in chronic stroke patients after two different condition are as follows. In the static balance ability and weight distribution symmetric index, the tactile feedback providing pressure information showed a significant difference compared to none feedback(p<.001).

Conclusion : The tactile bio-feedback providing pressure information in real time can support an improve in static balance ability, uniform weight bearing rehabilitation in chronic stroke patients.
