Stroke rehabilitation often uses the motor relearning concept that require patients to perform active practice of skill-specific training and to receive feedback. Treadmill training augmented with real-time visualisation feedback and functional electrical stimulation may have a beneficial synergistic effect on motor recovery. This study aims to determine the feasibility of this kind of enhanced treadmill training for gait rehabilitation among patients after stroke. A system for dynamic visualisation of lower-limb movement based on 3-dimentional motion capture and a computer timed functional electrical stimulation system was developed. Participants received up to 20-min enhanced treadmill training instead of their over-ground gait training once or twice a week for 6 weeks at Coathill hospital, Lanarkshire, United Kingdom. Number of training sessions attended, and training duration were used to assess feasibility. Ankle kinematics in the sagittal plane of walking with and without functional electrical stimulation support of the pre-tibial muscles were also compared and used to confirm the functional electrical stimulation was triggered at the targeted time. Six patients after stroke participated in the study. The majority of participants were male (5/6) with a age range from 30 to 84 years and 4/6 had left hemiplegia. All participants suffered from brain infarction and were at least 3 months after stroke. Number of training sessions attended ranged from 5 to 12. The duration of training sessions ranged from 11 to 20 min. No serious adverse events were reported. The computerised functional electrical stimulation to the pre-tibial muscles was able to reduce plantarflexion angle during the swing phase with statistical significance (p = 0.015 at 80%; p = 0.008 at 90 and 100% of the gait cycle). It is safe and feasible to use treadmill gait training augmented with real-time visual feedback and computer-controlled functional electrical stimulation with patients after stroke in routine clinical practice.

跑步机训练增强了实时可视化反馈和功能电刺激中风后步态康复：可行性研究。

中风康复经常使用运动再学习的概念，要求患者进行特定技能训练的积极练习并接受反馈。通过实时可视化反馈和功能性电刺激增强的跑步机训练可能对运动恢复产生有益的协同作用。本研究旨在确定这种增强型跑步机训练对中风后患者步态康复的可行性。开发了基于三维运动捕捉和计算机定时功能性电刺激系统的下肢运动动态可视化系统。参与者在英国拉纳克郡的 Coathill 医院接受了长达 20 分钟的增强型跑步机训练，而不是每周一次或两次地面步态训练，为期 6 周。参加的培训课程数量和培训持续时间用于评估可行性。还比较了胫前肌肉在有和没有功能性电刺激支持的情况下行走矢状面的踝关节运动学，并用于确认在目标时间触发了功能性电刺激。中风后的六名患者参加了这项研究。大多数参与者是男性（5/6），年龄范围为 30 至 84 岁，4/6 患有偏瘫。所有参与者都患有脑梗塞，并且在中风后至少 3 个月。参加的培训课程数量从 5 到 12 不等。培训课程的持续时间从 11 到 20 分钟不等。没有报告严重的不良事件。对胫骨前肌肉的计算机化功能性电刺激能够在摆动阶段减少跖屈角度，具有统计学意义（p = 0.015，80%；p = 0.008，90% 和 100% 的步态周期）。在常规临床实践中，对卒中后患者进行实时视觉反馈和计算机控制的功能性电刺激增强的跑步机步态训练是安全可行的。NCT03348215。2017 年 11 月 20 日注册。
