Abnormal facial sensation has a negative impact on patients' oral behaviors and may adversely affect a patient's quality of life if the altered sensation persists. Many patients with abnormal sensations retain some sensory function and do not develop chronic pain, and for those individuals there are currently no evidence-based noninvasive therapies. The goal of this project is to evaluate sensory re-training, a rehabilitative therapy that offers significant potential for patients who experience impaired sensory function regardless of the cause. This behavioral therapy approach has been used with substantial clinical success with hand injury patients since the 1970s. Re-training appears to enhance central reorganization of impulses from an injured sensory nerve to the cerebral cortex so that the altered sensory signals can be interpreted and translated into functionally meaningful motor functions.
