| Research Abstract |
Rehabilitation of trunkal motor dysfunction is very important for standing and walking of brain damaged patients. We developed a new "Computerized-Trunk Exercise Assisting System" with which we are repeatedly able to examine or to exercise the trunkal muscle strength and the sitting balance.
The subject sat on a chair, which was equipped with a gravimeter connected to a computer system to track automatically the movements of Center of pressure(COP). The seat was lifted up until the foot was free from the floor. COP was presented on a display in front of the subject. In the task, the subject was asked to lean his body so that his COP arrived the six indicated targets accurately from a home position as fast as possible. This system, in other words, is the examination of the trunkal muscle control function through visual and deep sensorial feedback control. The data of the COP movements were stored and analyzed with respect to range of COP movements, tracking speed and error in each direction.
We confirmed both the reliability and the reproducibility of these parameters in the normal subjects. Furthermore, we compared these parameters with the results of functional reach test, a traditional trunkal function test. There were no significant correlations between them. These results suggest that this system is useful for both the examination and the training for the trunkal function, and that the data obtained from this system may show a new visuo-trunkal motor function which we have not be able to obtain from the traditional assessment.
