Movement - unpredictable or jerky

Chorea; Muscle - jerky movements (uncontrolled); Hyperkinetic movements; Myoclonus; Ballismus

Jerky body movement is a condition in which a person makes fast movements that they cannot control and that have no purpose. These movements interrupt the person's normal movement or posture.

When abnormal movements are excessive, they are called ‘hyperkinetic’ movements and include myoclonus (jerking and twitching) and ballismus (violent flinging of extremities), chorea (slow, twisting, or continued movements), among others.
