The purpose of this research was to examine the effects of intervention activities such as singing and touching patients with severe motor and intellectual disabilities (SMID). Their bodily state, such as behavioral reactions and heartbeat reactions were comprehensively evaluated, and the effects of continuous intervention activities were also explored. The intervention activities mainly evaluated their physical condition before and after calling their names and playing or singing music. Their heartbeat interval and behavior were recorded. Music conditions were singing, touching, and singing while touching. Each of these was done at 60 and 120 tempos. Analysis of changes in their pulse rates showed that these intervention activities resulted in remarkably lower pulse rates in all three subjects, especially from the combined singing and touching. Therefore, it was presumed that the combination of sensory stimulation by music with sensory tactile pressure stimulation by touching is effective in altering heartbeat reaction. We also found cases where certain behavioral expressions with movements matched the heartbeat reactions. These findings suggest the possibility that the mental state of a patient with SMID can be inferred from their behavioral aspects, and indicates the importance of appropriate intervention activities.
