Study of Objective Evaluation of Effect of Psychological Relaxation Using Classic Music

摘要

Objective: Some of classic musics make both relaxation and adequate stress. In brain cortex some classic musics make fruitful concentration and attention.Design: A clinical study.Materials and methods: The subjects were healthy young 1 man and 19 women. We did them Tomita's stress questionnaire. They enjoyed classic music CD with headphone. Accelerated plethysmography (APG) was performed using a pulsimeter with the sensor positioned on the tip of the ventral side of the index finger. Peripheral venous circulation was monitored with venous oxygenation index (VOI) and width of peripheral vein.Results: Tomita's stress questionnaire scores were significantly correlated with low frequency (LF) component powers (maximum entropy method (MEM) and fast fourier transform (FFT)). LF and LF/HF decreased after enjoying classic music. VOI was significantly positive correlated with LF/HF before enjoying classic music.Conclusions: These results suggest that APG, VOI and width of peripheral vein is useful for objective evaluation of psychological stress and relaxation.
