A typical example of the temperature distribution registered by infrared thermography before, during, and after violet laser acupuncture at acupoint Dazhui (GV14) is shown in Fig. 2. Temperature increases at the stimulation area (þ0.7C), as well as at a “far field” area (+0.2C) Zhiyang (GV9) were noted.Fig. 3 summarizes the results of temperature analysis of the ten healthy volunteers. Skin temperature measured by infrared thermography changed significantly (p < 0.001) at a distance of 3 cm from acupoint Dazhui (red columns in Fig. 3). It was interesting that temperature also changed significantly (p < 0.05) at a so-called “far field” location (area below the spinous process of the 7th thoracic vertebra, parallel to the inferior angle of the scapula; Zhiyang [GV9]; blue columns in Fig. 3).Nonsignificant changes were found during stimulation by needle acupuncture (Fig. 3; circles); moreover, the placebo procedure with deactivated laser did not lead to any significant change (Fig. 3; squares).Stimulation with the violet laser at Dazhui also resulted in nonsignificant changes in standard monitoring parameters such as heart rate (a, 68.2 ± 10.2; b, 68.1 ± 9.7; c, 68.0 ± 9.4; d, 68.1 ± 9.9 bpm) and mean arterial blood pressure (before, 82.2 ± 10.3; after, 82.5 ± 7.3 mmHg).
