Assessing the Effects of Acupuncture by Comparing Needling the Hegu Acupoint and Needling Nearby Nonacupoints by Spectral Analysis of Microcirculatory Laser Doppler Signals
Figure 3
Comparison of the MBF between acupoints and nonacupoints. (a) Hegu experiment (n =13) and (b) control experiment (n =10). MBF is defined as the average value of LDF flux signal. Data are mean and SD values. *P < .05 and **P < .01, compared with the baseline value by two-tailed paired t-test. In the Hegu experiment, both effects at Hegu were significantly larger than the baseline value, whereas there were no significant effects at the nonacupoints. In contrast to the early effect, the later effect at Hegu tended to return to the baseline value. In the control experiment, there were no significant changes in the MBFs at the three sites.
