EXTRACORPOREAL PHANTOM TICS IN TOURETTES-SYNDROME

Some ties are intentional movements made in an attempt to diminish unc omfortable sensations. These sensations, sometimes termed sensory ties , are focal and usually arise in the part of the body involved in the subsequent motor act. We report a patient whose sensations associated with ties were felt in other people and in objects. The discomfort ass ociated with his out-of-body sensations was temporarily relieved by to uching or scratching the object involved. The definition of premonitor y sensations should be expanded to include extracorporeal sensations, and a history of external sensations should be sought in patients with Tourette's syndrome. Theories on the generation of ties must incorpor ate an explanation for extracorporeal sensations.
