Khảo sát cảm giác đắc khí và thay đổi nhiệt độ da khi châm thiêu sơn hỏa huyệt tam âm giao trên người khỏe mạnh

Abstract

Objectives: To investigate deqi sensation and changes in skin surface temperature following the Hot-Reinforcing technique at Sanyinjiao acupoint in healthy volunteers.

Subjects and methods: This experimental study involved 46 healthy volunteers aged 18–30, randomly assigned to two groups: The Hot-Reinforcing Technique or neutral acupuncture technique on the left Sanyinjiao acupoint. Skin temperature on both legs was measured using a FLIR C5 infrared camera before and after needling, and the deqi sensation was assessed throughout the acupuncture process.

Results: The Hot-Reinforcing Technique significantly increased skin temperature on the inner left lower leg (p<0.05). Participants in the Hot-Reinforcing Technique group reported significant deqi sensations, including soreness, heaviness, fullness, tingling, numbness, and warmth, compared to the neutral acupuncture technique group (p<0.05).

Conclusion: The Hot-Reinforcing Technique on the left Sanyinjiao acupoint can change skin surface temperature and produces distinct deqi sensations: Soreness, heaviness, fullness, tingling, numbness, and warmth compared to neutral acupuncture technique.
