Movements that are involuntary, brief, rapid, jerky, irregular, and unpredictable, involving distal limbs, trunk, and face, and that seldom repeat; this describes which disorder?

Movements described are characteristic of chorea. Chorea involves involuntary, brief, rapid, jerky, irregular, and unpredictable movements that can involve the distal limbs, trunk, and face, and they usually do not repeat in a fixed pattern. This sets it apart from tremor, which is rhythmic and oscillatory; dystonia, which causes sustained or repetitive twisting and abnormal postures; and tics, which are stereotyped, often suppressible, and typically preceded by a premonitory urge. Chorea arises from dysfunction in the basal ganglia circuits, with Huntington’s disease and Sydenham chorea as classic examples.
