Definition
Jactitation is a medical term that describes restless, repetitive movements, often rhythmic and involuntary. It can involve rocking, twitching, or other motor behaviors. Think of it as an extreme form of fidgeting, but often associated with underlying medical or psychological conditions. It's not simply being restless; it's a persistent, often uncontrollable movement. It is a symptom of a medical condition, such as neurological disorders or severe anxiety. Jactitation can be observed in different body parts. It contrasts with voluntary movement as the individual has little or no control over it.
