Objective To investigate the clinical efficacy of acupuncture at gastrointestinal Back-Shu and Front-Mu points for post-stroke functional constipation. Method Sixty-six patients with post-stroke functional constipation were randomized to treatment and control groups, 33 cases each. The treatment group received acupuncture at gastrointestinal Back-Shu and Front-Mu points: Weishu (BL21), Dachangshu (BL25), Xiaochangshu (BL27), Zhongwan (CV12), Tianshu (ST25) and Guanyuan (CV4). The control group took Chinese herbal medicine Liumo Decoction prescribed originally. The clinical therapeutic effects were compared between the two groups. The CCS score was recorded and fecal characteristics were scored in the patients at baseline, during treatment and at follow-up. Result The total efficacy rate was 90.9％ in the treatment group and 42.4％ in the control group. The CCS score and the fecal characteristic score were lower in the two groups after treatment compared with before (P<0.05) and the therapeutic effect was more marked in the treatment group (P<0.05). The CCS score and the fecal characteristic score increased in the two groups at follow-up, but the increments were significantly smaller in the treatment group than in the control group (P<0.05). Conclusion Shu-Mu point combination acupuncture can significantly relieve the symptoms of post-stroke functional constipation and change fecal characteristics. It is superior to Chinese herbal treatment alone.
