Induction of a relaxed state using a vibration stimulus based on the respiratory cycle

Abstract

The purpose of this study was to induce different states using a vibration stimulus based on an individual’s breathing cycle. Based on the results of Lorenz plot area S (LP-area-S), breathing control with the long-period breathing pattern was able to induce a state of increased parasympathetic activity. Parasympathetic activity was greatly reduced during the task with the short-period breathing pattern. The results of LP-area-S and the AAC (alpha attenuation coefficient) showed that LP-area-S was increased with the short- and long-period breathing patterns when AAC was decreasing. Given the results of this experiment, it appears that breathing control using a vibration stimulus based on individual breathing cycles can lead to a relaxed state in terms of the physiological and psychological changes.
