Electrical Stimulation for the Treatment of Post-Stroke Shoulder Pain

The SPR System is an investigational two-staged device which delivers stimulation to the shoulder. Subjects with chronic post-stroke shoulder pain who meet eligibility criteria for the first stage (SPR Trial Stage) will receive a temporary Lead and External Stimulator. Subjects who qualify and who agreed to proceed will advance to the second stage (SPR Implant Stage) which uses an Implantable Pulse Generator (IPG) and Implantable Lead. Subjects will be followed until 36-months after IPG stimulation has been started.
