  Purpose

This study will collect information on (tricks) patients with focal dystonia use to relieve their symptoms. Dystonia is a movement disorder caused by sustained muscle contractions often causing twisting and abnormal posturing. Dystonia may be generalized, affecting at least one leg and the trunk of the body, segmental, affecting adjacent body parts, or focal, affecting a single body part, such as the hand or eyelid. It may be task-specific, such as writer's, musician's or sportsman's cramps. Some patients with focal dystonia use (tricks), such as touching the face or hand, to stop or alleviate the abnormal movement. This study will survey the types of tricks people with focal dystonia use in order to learn more about the disorder.

Patients 18 years of age and older with focal dystonia may be eligible for this study. Candidates will be screened for eligibility with a medical history, clinical evaluation, and review of their medical records.

In one 30- to 45-minute clinic visit, participants will be interviewed about their dystonia symptoms and the tricks they use to relieve the symptoms. They may be asked to show the investigators how the tricks work

Detailed Description:

The purpose of this study is to collect and organize information concerning a phenomenon known as 'sensory tricks' or Geste antagoniste in focal dystonia. Sensory tricks, which we will refer to as 'tricks' since some involve motor as well as sensory input, are various stimuli used by dystonic patients to transiently diminish their spasms (Jankovic and Fahn 1993). The phenomenon of tricks is evidence for the abnormality of sensorimotor integration in focal dystonia, yet it is little studied or understood. A survey of the history and characteristics of tricks will lead to a better understanding of this puzzling phenomenon, and a step toward the understanding of the mechanism of focal dystonia.
