Abstract: OBJECTIVE: This study aimed to evaluate the influence of reduced visual information on postural control by comparing low-vision and normal-vision adults in static and dynamic conditions. METHODS: Twenty-five low-vision subjects and twenty-five normal sighted adults were evaluated for static and dynamic balance using four protocols: 1) the Modified Clinical Test of Sensory Interaction on Balance on firm and foam surfaces with eyes opened and closed; 2) Unilateral Stance with eyes opened and closed; 3) Tandem Walk; and 4) Step Up/Over. RESULTS: The results showed that the low-vision group presented greater body sway compared with the normal vision during balance on a foam surface (p <= 0.001), the Unilateral Stance test for both limbs (p <= 0.001), and the Tandem Walk test. The low-vision group showed greater step width (p <= 0.001) and slower gait speed (p <= 0.004). In the Step Up/Over task, low-vision participants were more cautious in stepping up (right p <= 0.005 and left p < 0.009) and in executing the movement (p <= 0.001). CONCLUSION: These findings suggest that visual feedback is crucial for determining balance, especially for dynamic tasks and on foam surfaces. Low-vision individuals had worse postural stability than normal-vision adults in terms of dynamic tests and balance on foam surfaces.
