Abstract
|
|
|
Infrared thermography for temperature distribution monitoring was performed in ten healthy volunteers (M/F, 5/5; mean age ¡¾ SD, 24.9 ¡¾ 3.3 years) before, during, and after stimulation by noninvasive violet (405 nm) laser needle at the Dazhui (GV14) acupoint. Significant (p < 0.001) increases of temperature at a region of interest around the acupoint were observed. Furthermore, temperature also increased significantly (p < 0.05) at a so-called ¡°far field¡± area Zhiyang (GV9). In two persons, however, needle acupuncture and placebo (deactivated laser) did not have the same temperature effects. Violet laser induces changes in skin surface temperature distributions.
