The disorder often leads to bodily injury from unwanted movements. Because of these incessant muscle contractions, patients' sleep patterns are often disrupted. It differs from restless legs syndrome in that RMD involves involuntary muscle contractions before and during sleep while restless legs syndrome is the urge to move before sleep. RMD ...
The reproduction of involuntary movement usually happens along the head-tail axis, having a left-right symmetry.

In most cases, the accompanying contralateral involuntary movements are much weaker than the ipsilateral voluntary ...

Psychomotor agitation is a symptom in various disorders and health conditions. It is characterized by unintentional and purposeless motions and restlessness, often but not always accompanied by emotional distress and is always an indicative for admission.
Researcher Vicky Williamson at Goldsmiths, University of London, found in an uncontrolled study that earworms correlated with music exposure, but could also be triggered by experiences that trigger the memory of a song (involuntary memory) such as seeing a word that reminds one of the song, hearing a few notes from the song, or feeling an emotion one associates with the song.
This neurological phenomenon is characterized by a sustained dystonic, conjugate, involuntary upward deviation of both eyes lasting seconds to hours. The term oculogyric is applied in reference to the simultaneous upward movement of both eyes, although the reaction may encompass a variety of additional responses. [ 1 ]
