- Electrical stimulation Device
Intervention Desc: This category includes any form of electrical stimulation intended to improve motor function or pain after stroke.
Randomized, controlled, evaluator-blinded, multicenter trial.
Subjects will be assigned to receive either PENS or TENS treatment. PENS treatment involves the temporary insertion of fine-wire electrodes into the shoulder. TENS treatment requires the subject to place adhesive patch electrodes around the shoulder. All subjects will receive 6 hours of stimulation treatment a day for 7 weeks, and will attend 6 office visits. Brief weekly telephone interviews will occur during the treatment period and at end-of-treatment and 3 and 6-month follow-up periods.
