The purpose of this study was to understand the influence of various information acquisition strategies on foot proprioception and obstacle avoidance in people with low vision. Ten adult males (41.0 ± 7.1 years) with pigmentary retinal degeneration were recruited for this study. Participants acquired obstacle information (obstacle height: 4 cm and 15 cm) through three different strategies, namely, front (A), downward (B), and tactile (C). Subsequently, the participants performed two different tasks; Task 1: After identification of the obstacles, the participants reproduced the obstacle height by lifting their foot while standing still (10 times). Task 2: Following the acquisition of the obstacle information through conditions B and C, participants performed obstacle step-over from a standing position. In task 1, condition B showed significantly higher toe-rise and coefficient of variance in toe-rise (p < 0.05) than in conditions A and C, which both displayed similar toe-rise. Likewise, in task 2, the highest points of the leading and trailing feet while stepping over the obstacle were significantly higher (p < 0.05) in condition B than in condition C. Additionally, the coefficient of effort in condition B was significantly larger (p < 0.05) than that of condition C. These results suggest that differences in information acquisition strategies have an impact on the foot trajectory during obstacle step-over. Out of the three methods used in this study, information acquisition through the tactile sense may be the best obstacle avoidance feedback method for people with low vision.
