Design, development, and optimization of the Somnomat Casa: a rocking bed for sleep studies and nocturnal interventions in home settings.
Autom.(2024)
Abstract
Abstract Vestibular Stimulation (VS) has been shown to positively affect various autonomic body functions, including sleep. In the past, VS was often investigated using large and complex rocking beds that would only allow for short intervention periods in constrained lab settings. In this work, we present an overview of the mechanics, kinematics, dynamics, and tuning of our latest rocking bed, the Somnomat Casa. Its compact dimensions, comparable to a standard single bed, its connectivity, and easy usability, allow for prolonged studies in home settings investigating the effects of VS during sleep. In a first six-month study with a 12-year-old boy suffering from primary mitochondrial disease with an associated severe sleep disorder, we observed significant improvements in sleep duration (+25 %) and quality of life, as well as a 75 % reduction in caregiving interactions and a 40 % reduction in overall caregiving time. Based on these promising findings, we are currently testing the Somnomat Casa with various patient groups for multiple months each, including elderly with insomnia, children with sleep disorders, Parkinson’s disease patients, and individuals with post-stroke insomnia.
