Infrared Thermography-based Study of the Warming Effect Difference at Waist

Patients allocated to the acupuncture group will be punctured at the pre-specified acupoints. According to the theory of traditional Chinese medicine and clinical experience, we will use the Bilateral Weizhong point (BL 40). Because of the similar anatomy, the Chize point (LU 5) was chosen as a control. Sterile disposable stainless steel acupuncture needles (length: 40 mm, diameter: 0.25 mm; Hwato, Suzhou, China) will be used.

Moxibustion Participants in the moxibustion group will receive moxibustion treatment via portable Moxibustion (Aikeshu, Bozhou, China); the moxibustion is composed of The inner tube (containing the moxa pillar) and the outer tube. To use, pull out the inner tube and light the moxa pillar, then insert the outer tube and fix the moxibustion on the acupuncture points. Two Moxibustion devices will be sequentially applied at two acupoints Weizhong (BL 40) and Chize (LU 5), for 30 minutes.
