Akathisia is a movement disorder characterized by a feeling of inner restlessness and a compelling need to be in constant motion, as well as by actions such as rocking while standing or sitting, lifting the feet as if marching on the spot, and crossing and uncrossing the legs while sitting.
Severe akathisia can become a very harrowing experience. Jack Henry Abbot (1981) describes the sensation: ...[It comes] from so deep inside you, you cannot locate the source of the pain â¦ The muscles of your jawbone go berserk, so that you bite the inside of your mouth and your jaw locks and the pain throbs.
