This study compared the effects of a laser needle with those of standard needles with regard to acupuncture treatment. Subjects were 5 volunteers who underwent treatment at the Gokoku point (LI4, Hegu) with a carbon-dioxide laser needle having an energy density of 10.4 J/cm2. At 5 and 10 minutes after irradiation, we measured surface temperatures at the Geiko (LI2, Yingxiang), Chiso (S4, Dicang), Kenryo (SI18, Quanlian), and Orbit points using thermograpy. At 70 minutes after laser irradiation, the volunteers underwent treatment with standard needles at the Gokoku point, and surface temperatures were measured in the same way as described above. The Geiko and Chiso points exhibited temperature rises after both laser needle and standard needle treatment. Interestingly, there was no difference in the temperature increases between the laser and standard needles. Other points showed little increase in temperature after treatment with either the laser or standard needles. These results indicate that the CO2 laser needle can be effective in acupuncture treatment.
