Research on the visual disabilities by the training of orientation and mobility with kinesthetic sence
orientation and mobility
Having well orientation and mobility is very important for the visual disability. Purpose：Compare the difference in the awareness of self-distance and the training effects upon diverse performance of visual disabilities with the different levels in walking distance, deviation and turn angle in a triangular route. Furthermore, explore the relation between visually disable level and body activity. Method： There were ten volunteers of congenitally visual disabilities to participate this experiment (four volunteers were middle- level, six volunteers were serious- level). All subjects joined the tests of awareness of self- distance, the training of a triangular route, and record the walking steps by carrying a pedometer for the duration of two weeks. Results：First, there was obvious difference between the middle- and serious- level groups in the awareness of 1 meter hand- distance. Second, the middle- level group’s distant awareness of the actual step was much correcter than the serious- level group’s. And most of subjects’ self- awareness of step distance was shorter than actual step distance. Third, in the awareness of 6 meter straight walking test, most of subjects were notably over 6 meter and had deviant condition. Fourth, before the training in a triangular route, the performance of the middle- level group in walking distance and deviation was better than the serious- level’s. But the serious- level group had marked advance after training. Fifth, after training, both of the middle- and serious- level groups had noteworthy advancement in the turn angle. Sixth, the levels of visual disabilities obviously affected the amount of body activity and walking custom. And the walking custom (unarmed or with a stick) was notable influence on the value of BMI. Conclusions：By offering test data and using kinesthetic sense to adjust themselves could be notably advance in the distant estimation and deviant control of short-distance walking, and turn angle control.
