title: [Clinical observation of preventing and treating constipation by electroacupuncture intervention in ischemic stroke patients at acute stage].
abstract: OBJECTIVE
  To observe the efficacy of preventing constipation by electroacupuncture intervention in ischemic stroke patients at acute stage.
  
  
  METHODS
  Three hundred and forty ischemic stroke patients who matched the inclusive criteria were randomly divided into an electroacupuncture (EA) group and a routine treatment group, 170 cases in each one. In the EA group, based on routine western treatment, rehabilitation training and common acupuncture, Tianshu (ST 25) and Zusanli (ST 36) were selected and connected to SDZ-V Hwato brand electric acupuncture apparatus respectively, given stimulation of dense-disperse wave (10 Hz/50 Hz) with electric current of 0.1 to 1.0 mA, once every day and 5 times a week in the first 2 weeks, 2 times a week in the latter 2 weeks. In the routine treatment group, only basic treatment was applied. In the two groups, the course of treatment was 4 weeks and 8 weeks' follow-up was required after treatment. The actual numbers who independently defecated less than 3 times a week after 1 to 4 weeks' treatment and in the 4th and the 8th weeks' follow-up and condition taking laxative medicines during the 12 weeks in the two groups were observed and compared.
  
  
  RESULTS
  Compared on the numbers of constipation cases after 1 to 4 weeks' treatment, those in the EA group were all less than those in the routine treatment group [24.7% (42/170) vs. 36.5%(62/170), 18.8% (32/170) vs. 30.6% (52/170), 10.5% (17/162) vs. 27.5% (44/160), 9.3% (15/162) vs. 19.4% (31/160),P<0.05, P<0.001]. In the 4th and the 8th weeks' follow-up, numbers in the EA group were still less than those in the routine treatment group [9.0% (14/156) vs. 18.1% (28/155), 7.7% (12/155) vs. 16.9 (26/154) both P<0.05)]. During the 12 weeks, the number of cases who took laxative medicines in the EA group was less than that in the routine treatment group [21.2% (36/170) vs. 34.7% (59/170), P<0.05].
  
  
  CONCLUSIONS
  There is clinical significance to electroacupuncture at Tian-shui (ST 25) and Zusanli (ST 36) coibined with basic comprehensive treatment for preventing and treating constipation symptom in ischemic stroke acute stage.
