PURPOSE : The purpose of this study was to examine the effect of visual control on gait speed and balance in patients with stroke. Static balance and gait speed were investigated with comparison and fixed direction of visual.
METHODS : We included twenty-six patients with stroke. Participants were measured static balance while standing on a forceplate with one of 4 different visual direction in front, floor, non-affected side and affected side for 30 seconds. To compare of the gait speed, participants had to walk with one of fixed visual direction. And to compare of gait speed with visual dispersion, gait speed were measured with visual change in left and right, up and down direction every 5m, 2m and 1m intervals.
RESULTS : The result of the static balance with fixed visual showed that the affected side and the non-affected side were shown significantly increased sway of total sway length, mediolateral distance, anteroposterior distance, average velocity(p<.05). The gait speed with fixed visual showed that affected side was significantly slower(p<.05). And the gait speed significantly increased as interval of visual dispersion decrease in the sagittal and horizontal plane(p<.05).
CONCLUSION : The results from this study showed that the visual direction effected on static balance and the faster visual movement made to increase the gait speed. Therefore the rehabilitation training with visual control may be implemented for stroke patients.
