The Change in Cutaneous Temperature When Using Acupuncture at TB-3 and BL-65 Acupoints in Healthy Participants

All participants underwent three 24-hour apart sessions. In each session, the acupuncturist inserted two sterile needles into the left and right acupoints with a 90-degree angle and 0.5 to 1 cun in depth for TB3, 0.3 to 0.5 cun for BL65, and 0.3 to 0.5 cun for SP3. The acupuncturist rotated the needle at an angle of 180-270 degrees within 1 minute, with a frequency of 60 - 120 times/minute for stimulation.
