ABSTRACT
Introduction: This study seeks to discuss the light wave transport characteristicsvariation along the pericardium Meridian under different pressures.Methods: We selected 36 healthy students at the school for this study, tied up thedesktop blood pressure cuff onto subjects’right proximal arms, fixed the detectionprobe immovably on the Neiguan (PC6) acupoint and the reference point which was1cm off the PC6, and collected the light signal along the meridian and non-meridianwhen the laser irradiate Jianshi(PC5), Ximen(PC4) and the corresponding referencepoints respectively under pressure of 0, 100, 130 and 160.Results: The differences in optical transport properties between meridian and nonmeridianwere significant: under the same pressures(0s, 100s,130s, and 160mmHg),the relative attenuation rate of optical signal at the same distance between meridianand non-meridian were significant(p0.05). Under four different pressure situations, the opticalsignal at acupoint(PC5) and non-acupoint(NP) along the meridian were significantlydifferent with the corresponding reference points along the non-meridian(P
