Hybrid Assistive Limb (HAL) is a wearable human assistant cyborg-type robot that helps lower-leg movement based on bioelectrical signals detected from the voluntary movement of the person wearing it. In this study, we developed a novel staged HAL treatment protocol for patients with acute stroke. The Regain Program for Gait with HAL (RPG-HAL) was formulated in four steps, based on the severity of limb paralysis. Twenty-one patients with acute stroke received a combination treatment of RPG-HAL and conventional rehabilitation. The feasibility and safety of RPG-HAL were evaluated based on changes in physical function and activities of daily living (ADL). RPG-HAL yielded improvement in gait speed, cadence, step length, and functional ambulation category (FAC). The effect size was >0.8 in all measurements. FAC (1.90) and Barthel Index (BI) (1.92) exhibited the highest scores. Twelve out of 14 patients with FAC 0 before RPG-HAL reached the upper FAC. Thus, earlier intervention using RPG-HAL as improving physical function, ADL, and gait ability in patients with stroke.
混合辅助肢体 (HAL) 是一种可穿戴的人类辅助仿生机器人，它根据佩戴者自愿运动检测到的生物电信号来帮助下肢运动。在这项研究中，我们为急性中风患者开发了一种新型分阶段 HAL 治疗方案。基于肢体瘫痪的严重程度，制定了带有 HAL 的步态恢复计划（RPG-HAL）。21 名急性中风患者接受了 RPG-HAL 与常规康复相结合的治疗。根据身体功能和日常生活活动（ADL）的变化，评估了 RPG-HAL 的可行性和安全性。RPG-HAL 可提高步行速度、步频、步长和功能性步行分类（FAC）。所有测量的效果量均>0.8。FAC（1.90）和巴氏指数（BI）（1.92）得分最高。在 RPG-HAL 之前，14 名 FAC 为 0 的患者中有 12 名达到了更高的 FAC。因此，尽早使用 RPG-HAL 干预可改善中风患者的身体功能、ADL 和步态能力。
