本研究旨在了解通过导游的肘部传播的信息对严重视障人士的步行本体感觉的影响。本研究招募了 12 名患有色素性视网膜变性的男性成年人。参与者通过两种方式获取有关台阶的信息（台阶高度：4、10 和 20 厘米）：在向导的帮助下（攀爬台阶时抓住向导的肘部；条件 A）或向下看（在距脚趾 30 厘米处观察障碍物；条件 B）。随后，参与者执行了两项任务。在任务 1 中，参与者通过静态站立时抬起脚（每条腿 10 次）来重现障碍物的高度。任务2：在获得两种情况下的步数信息后，参与者从可以一步完成运动的自由位置爬上台阶。对于任务 1，条件 B 表现出比条件 A 更高的脚趾上升和更高的脚趾上升方差系数。关于任务 2，在条件 B 下，前脚的最高点在上台阶时明显更高。这些结果表明，信息获取策略的差异会影响爬台阶时的脚轨迹。在本研究中使用的两种方法中，通过引导助手获取信息可以为视力低下的人在爬楼梯时提供更好的反馈。
This study aimed to understand the influence of information propagated through the guide’s elbow on foot proprioception among severely visually impaired people. Twelve male adults with pigmentary retinal degeneration were recruited for this study. Participants acquired information about steps (height of steps: 4, 10, and 20 cm) through two methods: being helped by a guide (grasping the guide’s elbow as they climbed the steps; Condition A) or looking downward (viewing the obstacle at 30 cm from their toes; Condition B). Subsequently, participants performed two tasks. In task 1, participants reproduced the height of the obstacles by lifting their foot during static standing (10 times per leg). Task 2: After acquiring information about steps in both conditions, participants climbed the steps from a free position in which they could complete the movement with one step. For task 1, condition B, showed a higher toe rise and higher coefficient of variance in toe rise than condition A. Regarding Task 2, the highest points of the leading feet while stepping up were significantly higher under condition B. These results suggest that differences in information acquisition strategies affect the foot trajectory when climbing steps. Of the two methods used in this study, information acquisition through guide helpers may provide better feedback for individuals with low vision when climbing steps.
