Summary

This study will examine how the brain operates during execution and control of voluntary movement and what goes wrong with these processes in disease. It will use electroencephalography (EEG) and electromyography (EMG) to compare brain function in normal subjects and in patients with focal hand dystonia. In dystonia, involuntary muscle movements, or spasms, cause uncontrolled twisting and repetitive movement or abnormal postures. Focal dystonia involves just one region of the body, such as the hand, neck or face.

EEG measures the electrical activity of the brain. The activity is recorded using wire electrodes attached to the scalp or mounted on a Lycra cap placed on the head. EMG measures electrical activity from muscles. It uses wire electrodes placed on the skin over the muscles.

Adult healthy normal volunteers and patients with focal hand dystonia may be eligible for this study. Patients will be selected from NINDS's dystonia patient database.

Participants will sit in a semi-reclining chair in a darkened room and be asked to move either their right index finger, right foot, or the angle of their mouth on the right side at a rate of one movement every 10 seconds. Brain and muscle activity will be measured during this task with EEG and EMG recordings.
