Stroke-induced lower extremity dysfunction has become a severe medical problem nowadays and effective rehabilitation methods are in great demand. In this work, a new real-time Electromyography-driven Functional Electrical Stimulation (FES) cycling system was developed to help chronic stroke patients with lower limb rehabilitation training. To evaluate the feasibility and effectiveness of this system, 3 chronic stroke subjects were recruited and each received 20 training sessions where real-time Electromyography (EMG) was used to interact with the cycling system. During the training, two typical metrics, averaged Area Under Torque (AUT) and maximal EMG amplitude, were adopted to measure the muscle strength changes of hamstring (HS). The training results showed that the two measurements of HS both significantly increased, especially the maximal EMG amplitude in the last trial was twice as much as that in the first trial, indicating paretic limb strength increment and functional recovery, which suggested that our system is effective and helpful in the stroke rehabilitation.
中风引起的下肢功能障碍已成为当今严重的医学问题，因此对有效的康复方法有巨大需求。在这项工作中，开发了一种新型的实时肌电图驱动的功能性电刺激（FES）循环系统，以帮助慢性中风患者进行下肢康复训练。为了评估该系统的可行性和有效性，招募了3名慢性中风受试者，每人接受20次训练，训练过程中使用实时肌电图（EMG）与循环系统进行交互。在训练期间，采用两个典型指标，即平均扭矩下面积（AUT）和最大肌电图幅度，来测量腘绳肌（HS）的肌肉力量变化。训练结果表明，HS的这两项测量值均显著增加，尤其是最后一次试验中的最大肌电图幅度是第一次试验的两倍，表明患侧肢体力量增加和功能恢复，这表明我们的系统在中风康复中是有效且有帮助的。
