Abstract:
During and after the LI4 and LI10 Acupuncture, the volume elastic modulus Ev in the basal phalanx of finger arteries were measured. Ev values were noninvasively obtained using a new type of plethysmograph called the “electric impedance-cuff” which can detect indirect arterial pressure and volume change in the artery. After 15 minutes of rest, 2 minutes acupuncture on LI4 and LI10 were carried out in 16 healthy subjects, respectively. Volume elastic modulus showed a significant decrease (p<0.01) during and after the LI10 Acupuncture. Its decrease were maintained at least 20 minutes after the withdrawal of the needle. While the Ev values did not show the typical change during and after the LI4 acupuncture. These date suggest that the elasticity of the peripheral wall was lagely affected by the LI10 acupuncture, and the effect was caused not only by peripheral reflex but by other factors.
