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.

Study conducted and completed to determine if the calcium channel blockers, amlodipine can augment the effect of botulinum toxin injections in the treatment of focal dystonia.

Study will examine how the brain controls speech in patients with spasmodic dysphonia, a voice disorder that involves involuntary spasms of muscles in the larynx (voice box), causing breaks in speech. Although the causes of spasmodic dysphonia are unknown, recent studies found changes in brain function in patients with the disorder that may play a role in its development.
