Rhythmic movement disorder (RMD) is a childhood onset sleep disorder that is characterised by repetitive movements that involve large muscle groups, such as body rocking, rolling and head banging. These rhythmic movements are performed prior to and during sleep and as such can disturb sleep with clinical consequences. There is no standard measure to quantify the severity of rhythmic movements. 3D video offers a contactless method of achieving this without disrupting the child's sleep. Vestibular stimulation has a soothing effect and might be effective in promoting sleep. Furthermore, mild vestibular stimulation in the form of gentle rocking movements generated by the Somnomat device might function as a stimulation substitute for the child's RMD with therapeutic potential.~This study aims to a) investigate the feasibility of the detection of episodes of RMD using contactless 3D video analysis and customised analysis software and b) the use of vestibular stimulation as a therapy for childhood rhythmic movement disorder.
