Electromyographic biofeedback use in the treatment of voluntary posterior dislocation of the shoulder: a case study

Voluntary posterior dislocation of the shoulder has been difficult to treat successfully. Electromyographic biofeedback is a nonoperative treatment measure that has been successfully used for this condition in three previously reported cases. The purpose of this article is to present a case history in which electromyographic biofeedback was used successfully as part of a nonoperative treatment program for voluntary posterior dislocation of the shoulder.
