A randomized controlled study on acupuncture treatment of levator ani syndrome

INTERVENTION: Acupuncture group:After communicating with the patient, the patient was instructed to take the prone position and the local skin was routinely disinfected. The acupuncturist acupunctured the patient 's bilateral Zhongliao ( sacrum, right in the third sacral foramen ) and Xialiao ( sacrum, right in the fourth sacral foramen ). Operation : 3‐inch filiform needle ( 0.35 * 0.75mm ) was punctured into the posterior sacral foramen, obliquely punctured 75mm, the tip of the needle was in the direction of the inner side and the root of the thigh. The needle body was 30 o angle with the longitudinal axis of the human body and 60 o angle with the skin. After acupuncture, the needle was gently lifted, inserted and twisted to obtain qi. After obtaining qi, the needle sensation was radiated to the anus. Bilateral Zhongliao and Xialiao points were connected with electroacupuncture at a frequency of 2 / 15 Hz and a stimulation intensity of 1 5 mA, which was based on patient comfort. Retain the needle for 30 minutes, no needle during the needle retention process.;sham acupuncture group:After communicating with the patient, the patient was instructed to take the prone position and the local skin was routinely disinfected. The acupuncturist took the bilateral false Zhongliao point to open 20 mm outward at the bilateral Zhenzhongliao point, the bilateral false Xialiao point to open 20 mm outward at the bilateral Zhenxialiao point, and the shallow acupuncture was 3‐5 mm. The electroacupuncture electrode placement and parameter setting were the same as those in the acupuncture group. Acupuncture had no operation of deqi, and electroacupuncture had no output. Retain the needle for 30 minutes, no needle during the needle retention process.; CONDITION: levator ani syndrome PRIMARY OUTCOME: Clinical treatment efficiency; SECONDARY OUTCOME: Pain days per month;life quality evaluation;psychological assessment;anorectal manometry;Pelvic floor surface electromyography detection;tcm syndrome score; INCLUSION CRITERIA: Subjects must meet all the following requirements : ( 1 ) Patients who met the diagnostic criteria for levator ani syndrome ( functional gastrointestinal disease Rome IV ) ; ( 2 ) Patients with chronic or recurrent anorectal pain, each pain lasted at least 30 minutes, at least once a week, symptoms appear = 1 year, rectal examination : puborectalis traction pain ; ( 3 ) Age 20 to 70 years old, gender is not limited ; ( 4 ) Those who did not receive acupuncture treatment 3 months before enrollment ; ( 5 ) Participants voluntarily participated and signed informed consent
