Acupuncture
"The main acupoints include Guanyuan (CV4), Zhongwan (CV12), Shangyintang (EX-HN3), bilateral Tianshu (ST25), bilateral Zusanli (ST36), bilateral Hegu (LI4), and bilateral Taichong (LR3). The patient adopts a supine position, and after disinfecting the acupoints, sterile cotton pads are affixed to secure needles.~In the experimental group, filiform needles measuring Φ0.30×40mm are inserted into the skin to a depth of 0.5-1 cun, achieving De Qi sensation. Needles are retained for 30 minutes. At each acupoint (except Shangyintang), manual stimulation including lifting, thrusting, twisting, and plucking is performed once every 10 minutes. The participants received 12 acupuncture sessions over a 4-week period, with three sessions per week scheduled every other day."
Sham Comparator
The acupoints are same with those in the experimental group. The patient adopts a supine position, and after disinfecting the acupoints, sterile cotton pads are affixed to secure needles. The control group use dull needles measuring 0.30 × 25 mm, which are inserted vertically through the fixed pad until reaching the skin surface. The needles are gently lifted, twisted, and rotated slightly three times each, without piercing the skin. The needles are retained for 30 minutes, with no manipulation during this period. The participants received 12 sham acupuncture sessions over a 4-week period, with three sessions per week scheduled every other day.
