Effect of Clothing Pressure on ANS and CNS

研究服装压力对自主神经系统（ANS）和中枢神经系统（CNS）的影响。以心率变异性、鼓膜、皮肤温度和皮肤血流量作为中枢神经系统活动的指标，以偶发负变异（CNV）、事件相关电位和脑电图（EEG）作为中枢神经系统活动的指标。ANS的活性与压力有关。PNS活性随着压力从0 mmHg增加到10 mmHg而降低。然而，从10毫米汞柱增加到20毫米汞柱。SNS活动也表现出相同的趋势，但其活动的最低水平是在较低的压力下，与10 mmHg相比。10 mmHg的压力也会降低中枢神经系统的活性。

This study was to investigate the effect of clothing pressure on the autonomic nervous system (ANS) and central nervous system (CNS). Heart rate variability, tympanic membrane, skin temperature and skin blood flow were measured as an index of the activity of ANS. Contingent Negative Variation (CNV), one of event related potential and EEG were measured as that of CNS. ANS activity was dependent on the pressure. PNS activity was decreased by the increase of the pressure from 0 mmHg to 10 mmHg. However, it was increased from 10 to 20 mmHg. SNS activity also showed the same tendency, but the minimum level of its activity was obtained at the lower pressure compared with 10 mmHg. CNS activity was also decreased by the pressure of 10 mmHg.
