A functional electrical stimulation (FES)-robot system controlled by subjects' motor intention was developed in our previous study. The effectiveness of the FES-robot on wrist training was investigated in this work. Five hemiplegic subjects with chronic stroke were recruited for an FES-robot assisted wrist training with 20 sessions. After the training, motor improvements were found in the wrist and...
The effect of using robots to improve motor recovery has received increased attention, while the treatment effectiveness remains a topic of study. We compared the training effects by treatments on the wrist joint of chronic stroke patients with an electromyography (EMG)-driven robot (interactive group, n = 15) and a robot with continuous passive motion (passive group, n = 12) by a randomized controlled...
In this study, we introduced a new index, namely overlap index, to quantify the spatial resolution of cortical activity for muscle coordination based on the measurement of EEG-EMG coherence during a motor task. By applying this index on 4 control and 4 hemisphere chronic stroke subjects we successfully identified that there is a significantly increased overlap between biceps brachii at the elbow and...
