摘要

目的康复技术可用于中风后早期阶段的强化训练。本研究旨在评估机器人技术与功能性电刺激(FES)相结合的可行性,并采用 "按需辅助 "的方法为(亚)急性中风患者主动启动的腿部运动提供支持。方法九名亚急性中风患者在有辅助和无辅助的情况下重复进行踝关节背屈和/或膝关节伸展运动。根据 "按需辅助 "算法确定每次重复所需的辅助量和类型。通过描述性统计对有无辅助的重复次数和运动范围进行了比较。结果有 44% 的踝关节背屈重复动作和 5% 的膝关节伸展重复动作需要辅助,膝关节和踝关节的疲劳评分中位数分别为 2.0(IQR:0.2)和 4.0(IQR:1.5),表明有轻度至中度的疲劳感。事实证明,这种方法对踝关节背屈尤其有用。未来的研究应侧重于在临床环境中实施这种方法,以评估其临床适用性和对腿部功能的潜在影响。

Combining robotics and functional electrical stimulation for assist-as-needed support of leg movements in stroke patients: A feasibility study

Purpose

Rehabilitation technology can be used to provide intensive training in the early phases after stroke. The current study aims to assess the feasibility of combining robotics and functional electrical stimulation (FES), with an assist-as-needed approach to support actively-initiated leg movements in (sub-)acute stroke patients.

Method

Nine subacute stroke patients performed repetitions of ankle dorsiflexion and/or knee extension movements, with and without assistance. The assist-as-needed algorithm determined the amount and type of support needed per repetition. The number of repetitions and range of motion with and without assistance were compared with descriptive statistics. Fatigue scores were obtained using the visual analogue scale (score 0–10).

Results

Support was required in 44 % of the repetitions for ankle dorsiflexion and in 5 % of the repetitions of knee extension, The median fatigue score was 2.0 (IQR: 0.2) and 4.0 (IQR: 1.5) for knee and ankle, respectively, indicating mild to moderate perceived fatigue.

Conclusion

This study demonstrated the feasibility of assist-as-needed assistance through combined robotic and FES support of leg movements in stroke patients. It proved particularly useful for ankle dorsiflexion. Future research should focus on implementing this approach in a clinical setting, to assess clinical applicability and potential effects on leg function.
