1P2-J05 Verification of Sleep Inducing Effect in Adults by Mother's Embracing and Rocking Motion

Abstract

Recently, twenty percent of Japanese have insomnia problems. The final aim of our project is to develop a sleep inducing machine having rocking motion. As rocking motion, the motion of a mother's embracing and rocking of a baby is adopted. In a previous study, we analyzed the mother's rocking motion and derived two models for baby's motion consisting of linear motion and rotation motion. And we determined the candidate of rocking motion having sleep inducing effect among ten rocking motion. In this paper, we verified sleep inducing effect by the candidate of rocking motion. For this purpose, we compared the sleeping stage with/without rocking motion for ten healthy adults. As a result, there are significant difference between the rocking motion and no rocking motion.
