Outline of Final Research Achievements

Nine infants aged 3-6 months and their mothers were recruited at an infant massage class.Near-infrared light from the laser diodes of a multichannel f-NIRS system (LABNIRS; Shimadzu Corporation, Kyoto, Japan) was directed at the forehead through fibre optic bundles. The mothers massaged the infants for 15 sec, followed by a 15-sec rest period, approximately 10 times session. The oxy-Hb concentration was reduced in six of the nine infants after 5 sec of tactile stimulation. After 5 sec, the rate of reduction was 66.7%, and it was 77.8% after both 10 sec and 15 sec of tactile stimulation. Even at the finishing massage 5 sec later, the rate of reduction was 88.9%. This study suggests that tactile stimulation by massage reduces the concentration of oxy-Hb in the infant brain. Massage therapy can be used to reduce the brain activity of infants and relax and comfort them.
