Painful supernumerary phantom arm following motor cortex stimulation for central poststroke pain. Case report.
In this report, the authors describe a case in which the patient began to experience a supernumerary phantom arm after she received motor cortex stimulation for central pain. The patient had a history of right thalamocapsular stroke. It is speculated that the motor cortex activation triggered a response in the patient's parietal lobe, precipitating perception of the phantom limb. To the authors' knowledge this is the first reported case of its kind.
