Abstract
|
|
|
|
Infrared thermography for temperature distribution monitoring was performed in ten healthy volunteers (M/F, 5/5; mean age ± SD, 24.9 ± 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.
