Sensory Training to Treat Focal Dystonia
Sensory Training for Treatment of Focal Dystonia
This study will examine the effectiveness of Braille reading as a sensory training program for improving symptoms of focal (localized) dystonia, a movement disorder caused by sustained muscle contractions. Musicians, writers, typists, athletes and others whose work involves frequent repetitive movements may develop focal dystonia of the hand. Dystonia patients have an impaired sense of touch, and it is thought that symptoms may improve with sensory tactile (touch) training.
Patients with task-specific dystonia and healthy normal volunteers may be eligible for this 8-week study. Patients will undergo evaluation of their dystonia and a complete neurologic examination. Healthy volunteers will have a complete physical examination.
On the first day of the study, after 4 weeks and after 8 weeks, all participants will have a gap detection test for sensory perception testing. The test uses eight plastic devices called JVP-Domes with ridges of different widths on the surface. The subject's arm and hand are held in palm-up position and the right index finger is tested for about 1 second 20 times with each dome. The subject is asked to report whether the direction of the dome is vertical or horizontal. The test takes about 30 minutes. Patients with dystonia will also have a their symptoms evaluated at these visits. The evaluation involves completing a written questionnaire and writing a paragraph.
All participants will be trained in Braille reading at NIH. Sessions will be given every day the first week, twice a week the second and third weeks, and once a week the following weeks.
