National Institute of Neurological Disorders and Stroke NINDS study will use high-resolution magnetic resonance imaging (MRI) to look for subtle differences in brain anatomy between patients with focal hand dystonia (also called writer's cramp) and healthy normal volunteers. Patients with hand dystonia have prolonged muscle contractions that cause sustained twisting movements and abnormal postures. These abnormal movements often occur with activities such as writing, typing, playing certain musical instruments such as guitar or piano, or playing golf or darts.
