Balance performance under varied conditions of sensory cues

43 junior-high-school girls performed three trials on a dynabilometer on each of seven days. After learning the balance task with all sensory cues available, subjects were tested under three conditions of partial feedback occlusion, i.e., with earphones, blindfold, and combination of earphone and blindfold. When visual feedback was absent, performance deteriorated significantly. Such deterioration did not occur when hearing was occluded.
