English term or phrase:Rhythmic movement disorder
Rhythmic movement disorder
From Wikipedia, the free encyclopedia
Rhythmic Movement Disorder (or RMD) is a neurological disorder characterized by involuntary (however may sometimes be voluntary), repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was independently described first in 1905 by Zappert as jactatio capitis nocturna and by Cruchet as rhythmie du sommeil. The majority of RMD episodes occur during NREM sleep, although REM movements have been reported. RMD is often associated with other psychiatric conditions or mental disabilities. The disorder often leads to bodily injury from unwanted movements.
