Vestibular Stimulation Therapy for Rhythmic Movement Disorder
- Conditions
- Sleep Related Rhythmic Movement Disorder (Disorder)
- Interventions
- Other: SoundDevice: Somnomat B
- Registration Number
- NCT03528096
- Lead Sponsor
- Swiss Federal Institute of Technology
- Brief Summary
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.
- Detailed Description
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.

Group Intervention Description Baseline night Sound The sound of the moving bed is played back to the participant at the right sound intensity level. Intervention night Somnomat B Vestibular stimulation, in the form of gentle rocking movements, is provided using the Somnomat B rocking bed. Stimulation is provided for the first 60 minutes of the night and for 10 minutes upon detection of symptoms. The stimulation frequency is in the range of 0.25-2 Hz.
- Primary Outcome Measures
Name Time Method Effect of Therapy on Subjective Sleep Quality 2 nights Difference in perceived sleep quality between baseline and intervention nights. Data is collected in the first hour after awakening using a questionnaire.
Reliability of Automatic Detection of Symptoms 3 nights Episodes of rhythmic movement scored by an algorithm using 3D Video will be compared to the scoring of an expert
- Secondary Outcome Measures
Name Time Method Effect of Therapy on Symptoms 2 nights Severity of symptoms is determined based on 2D video recordings. The number of episodes of rhytmic movement (count) and the duration of episodes (minutes) compared between baseline and intervention nights.
Effect of Therapy on Objective Sleep Quality 2 nights Sleep quality is determined based on 2D video recordings and compared between baseline and intervention nights.
Preferred Stimulation Parameters 1.5 hours Participants can try out different directions of movement (pitch or roll) and different movement frequencies between 0 and 2 Hz and choose their preferred settings (one direction + one frequency).
