This study investigated whether electrical stimulation (ES) prior to a hand function training session for a total of eight weeks can better improve neuromuscular control and hand function in subacute stroke individuals and change electroencephalography-electromyography (EEG-EMG) coherence, as compared to the control (sham ES).
Subjects were randomly assigned into ES and control groups. Both groups received 20-minute hand function training twice a week, and the ES group received 40-minute ES on the median nerve of the affected side before each training session. The control group received sham ES - electrodes were placed on the same location but no electric current was applied. EEG, EMG and Fugl-Meyer Assessment (FMA) were collected before, at the 4th week, at the end of 8th week, and 4 weeks after the end of intervention.

sensory electrical stimulation was applied prior to upper limb functional training
electrodes were placed on the same location as the Electrical stimulation condition, but no electric current was applied
Fugl-Meyer Assessment for Upper Extremity
evaluate changes in upper extremity function of the stroke subjects
Time frame: before intervention, four weeks after, at the end of the eight-week intervention and four weeks after the intervention period ended
EEG-EMG coherence
evaluate changes in functional connectivity between motor cortex and active muscles
Time frame: before intervention, four weeks after, at the end of the eight-week intervention and four weeks after the intervention period ended
