Electrical Stimulation Combined With Motor Training on EEG-EMG Coherence and Motor Function in Individuals With Stroke

Completed

Phase N/A Results N/A

Trial Description

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).

Detailed Description

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.

Conditions

Interventions

  • Electrical stimulation Other
    Intervention Desc: sensory electrical stimulation was applied prior to upper limb functional training
    ARM 1: Kind: Experimental
    Label: Electrical stimulation
  • Sham electrical stimulation Other
    Intervention Desc: electrodes were placed on the same location as the Electrical stimulation condition, but no electric current was applied
    ARM 1: Kind: Experimental
    Label: Control

Outcomes

Type Measure Time Frame Safety Issue
Primary Fugl-Meyer Assessment for Upper Extremity before intervention, four weeks after, at the end of the eight-week intervention and four weeks after the intervention period ended
Primary EEG-EMG coherence before intervention, four weeks after, at the end of the eight-week intervention and four weeks after the intervention period ended
