Assessing the Effects of Acupuncture by  Comparing  Needling the Hegu Acupoint and Needling Nearby Nonacupoints by Spectral Analysis of Microcirculatory Laser Doppler Signals

<table>Possible mechanism underlying the changes in the HR and the microcirculatory parameters at the needled site. Applying AS in the Hegu experiment led to significant changes in the HR, the RECs of FR2, and the REC of FR5 at the needled site.</table>
