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

<table>Locations of measurement sites. Measurement sites: “O", Hegu acupoint (Site 1); “X", nearby nonacupoints (lower: Site 2, halfway between Hegu and Yangxi; upper: Site 3, halfway between Hegu and Sanjian); and “open triangle", location of the thermistor. Typical size of the hyperemic response (when it occurred) induced by the inserted needle is indicated. The diameter of the hyperemic response was never larger than 3 mm, which is smaller than the area of the LDF probe head (diameter <i>~</i>6 mm).</table>
