背景：使用混合辅助肢 (R) (HAL (R)) 进行步态训练可能对中风后步态功能和独立行走产生有益影响。然而，使用 HAL (R) 进行步态训练对中风患者的中长期疗效仍不清楚。 目的：比较偏瘫侧使用单腿版混合辅助肢 (R) (HAL (R)) 进行步态训练与传统步态训练 (CGT) 在恢复期中风患者中的中期疗效。 方法：24 名中风后参与者（HAL (R) 组：n） = 12，CGT 组：n = 12) 完成试验。在 4 周内，所有参与者均接受了 12 次时长 20 分钟的 HAL (R)（在瘫痪侧使用 HAL (R) 的单腿版本）或传统（由熟练且经验丰富的物理治疗师进行）步态训练。在训练前、12 次训练后以及干预开始后 8 周和 12 周对结果指标进行评估。功能性步行类别 (FAC) 是主要结局指标。结果：与传统组相比，HAL (R) 组在 12 次疗程后、第 8 周和第 12 周时 FAC 显着改善（P = 0.02）。结论：结果表明，在干预后 1 个月和 2 个月，基于 HAL (R) 的步态训练计划可能比 CGT 更有效地改善独立行走。
BACKGROUND: Gait training using the Hybrid Assistive Limb (R) (HAL (R)) may have beneficial effects on post-stroke gait function and independent walking. However, the long-term and medium-term efficacies of gait training using HAL (R) in stroke patients remain unclear.OBJECTIVE: To compare the medium-term efficacy of gait training using a single-leg version of the Hybrid Assistive Limb (R) (HAL (R)) on the paretic side with conventional gait training (CGT) in recovery-phase stroke patients.METHODS: Twenty-four post-stroke participants (HAL (R) group: n = 12, CGT group: n = 12) completed the trial. Over 4 weeks, all participants received twelve 20-min sessions of either HAL (R) (using the single-leg version of HAL (R) on the paretic side) or conventional (performed by skilled and experienced physical therapists) gait training. Outcome measures were evaluated prior to training, after 12 sessions, and at 8 and 12 weeks after intervention initiation. Functional Ambulation Category (FAC) was the primary outcome measure.RESULTS: The HAL (R) group showed significant improvement in FAC after 12 sessions, and at 8 and 12 weeks compared to the conventional group (P = 0.02).CONCLUSIONS: The results suggested that a gait training program based on HAL (R) may improve independent walking more efficiently than CGT at 1 and 2 months after intervention.
