Dystonia (literally, "abnormal muscle tone") is a generic term used to describe a neurological movement disorder involving involuntary, sustained muscle contractions. Dystonia may affect muscles throughout the body (generalised), in certain parts of the body (segmental), or may be confined to particular muscles or muscle groups (focal). ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

The precise cause of primary dystonia is unknown. In many cases it probably involves some genetic predisposition towards the disorder combined with environmental conditions.
