Facial paralysis rehabilitation: retraining selective muscle control.

Traumatic facial paralysis can be improved with surgical techniques but alone will not restore full function. EMG sensory (bio) feedback can, however, facilitate rehabilitation. Four cases are described using a combined treatment technique of EMG, behavioural modification and specific action exercises. Retraining of eyelid control was also accomplished. Standardized evaluation methods are described. All four patients showed improvement, despite the failure of traditional retraining methods.
