Electromyographically triggered electric muscle stimulation for chronic hemiplegia


Phase N/A Results

Trial Description

To evaluate electromyographically triggered electric muscle stimulation (EMS) in combination with conventional treatment in post-cerebrovascular accident outpatients.


  • Electrical stimulation Device
    Intervention Desc: This category includes any form of electrical stimulation intended to improve motor function or pain after stroke.

Trial Design

Controlled trial of 69 patients.

Patient Involvement

All patients had undergone conventional therapy with little or no functional recovery. Electromyographic (EMG) recordings and EMS directed to prime movers of impaired movements were accomplished by way of skin-surface electrodes. Prescribed treatment (patient compliance was frequently substandard) involved several months of four to five sessions per week, focusing on wrist extension and/or ankle dorsiflexion initially, and often other movements later. During 30 to 300 movement attempts per session, EMGs that exceeded a preset threshold triggered immediate stimulation to force movement completion.
