A movement disorder affecting the limbs, trunk, and facial muscles that is characterized by involuntary, unpredictable jerking movements.

A neurological condition affecting the involuntary movements. It is characterized by brief, non-repetitive irregular muscle contractions. It is seen in patients with Huntington's disease.

Ceaseless occurrence of rapid, highly complex jerky movements that appear to be well coordinated but are performed involuntarily.

characterized by random and involuntary quick, jerky, purposeless movements. Seen in Huntington's disease.

Chorea (Greek for 'dance') refers to widespread arrhythmic involuntary movements of a forcible, jerky and restless fashion. It is a random-appearing sequence of one or more discrete involuntary movements or movement fragments. Movements appear random because of variability in timing, duration or location. Each movement may have a distinct start and end. However, movements may be strung together and thus may appear to flow randomly from one muscle group to another. Chorea can involve the trunk, neck, face, tongue, and extremities.

Involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement. Hypotonia and pendular reflexes are often associated. Conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as CHOREATIC DISORDERS. Chorea is also a frequent manifestation of BASAL GANGLIA DISEASES.

Chorea, neurological disorder characterized by irregular and involuntary movements of muscle groups in various parts of the body. The principal types of chorea are Sydenham chorea (St. Vitus dance) and Huntington...
