| Research Abstract |
We noninvasively evaluated the condition of the peripheral venous circulation, such as the width of the peripheral vein and venous oxygenation index (VOI), using near-infrared spectrophotoscopy of Astrim SU (Sysmex, Inc., Co.). We also noninvasively evaluated the indices of autonomic nervous function such as the power values of the low frequency component (LF) and high frequency component (HF) and LF/HF ratio using the spectral analysis of heart-rate variability by measuring the acceleratingly plethysmogram (APG) waves.We examined whether or not the width of the vein, VOI, and indices such as LF, HF, and LF/HF were useful for the objective evaluation of the response to a psychological stressor and psychologicalrelaxation to music therapy. The subjects were 51 healthy university students.We used Raven’s colored progressive matrices as a psychological stressor. We examined the indices of autonomic nervous function using Artett type C and the vessel width and VOI using Astrim SU before an

d after Raven’s colored progressive matrices. After the psychological stressor, HF reduced and LF/HF increased. The width of the peripheral vein showed a significant negative correlation with LF/HF. According to the psychological stressor, the parasympathetic activity reduced, sympathetic activity was promoted, and the width decreased with sympathetic activity.The music therapy employing classical music significantly reduced LF and LF/HF. Before the music therapy, VOI showed a significant negative correlation with HF and a positive correlation with LF/HF. Before and after the music therapy, the stress score using the questionnaire showed a significant positive correlation with LF. Therefore, we concluded that, after the music therapy, the sympathetic activity reduced, and suggested that, during rest before the music therapy, VOI decreased with parasympathetic activity and increased with sympathetic activity. We speculated that the sympathetic activity increased with the subjective psychological stressor irrespective of before or after music therapy.in conclusion, the Artett type C and Astrim SU may become new, useful devices to measure psychological stressors and evaluate the effect of music therapy objectively.
