Abstract
In order to examine the relation between visual field and gait stability, 10-m walking time and coefficient of variation (CV) of 10 trials were obtained from 8 healthy adult subjects under the 4 different conditions of visual fields; without visual constriction, with left homonymous hemianopsia, with left homonymous three fourths hemianopsia, and with complete visual block. With complete visual block, the walking time nearly doubled, and CV was significantly greater, compared with other conditions of visual fields. CV with left homonymous hemianopsia and that with left homonymous three fourths hemianopsia was almost the same as that without visual constriction. These results suggest that the supply of sensory information like lighting of steps or installation of handrails is important for the elderly disabled who have a decreased reserve balance.
