Official title
Acupuncture for the Treatment of Parkinson's Disease Related Constipation
Overview
The purpose of the study is to evaluate the efficacy of acupuncture in treating Parkinson's disease related constipation (PDC). In the randomized controlled clinical trial study, patients meeting the criteria for inclusion will be randomly enrolled and divided into two groups in a 1:1 ratio: the acupuncture group and the sham acupuncture group. The intervention is going to be executed using the acupoints EX-HN1（Sishencong),LI4 (Hegu),ST25 (Tianshu),ST37(Shangjuxu),ST36(Zusanli),ST44 (Neiting), ST44 (Taichong), SP6 (Sanyinjiao) and CV4 (Shuangyuan).The acupuncture needles will be inserted to a depth of 0.8 to 1 cm in the acupuncture group. The sham acupuncture group's needles will be inserted to a depth of 0.2 to 0.3 cm with nonacupuncture points located 0.5 cm in lateral to the real acupoint or to the right for midline points. During the study, researchers will observe changes in complete spontaneous bowel movements (CSBMs), Constipation Symptom and Efficacy Assessment Scale (CSEAS) (including the six dimensions of difficulty, Bristol, time, incompleteness, frequency,and bloating), the Patient-Assessment of Constipation Quality of Life questionnaire (PAC-QOL), and the Unified Parkinson's Disease Rating Scale (UPDRS) at baseline (week 0), post-treatment (week 4), and follow-up (week 12).Colonic transit time measurement and conventional anorectal manometry were evaluated at the above time points.
Detailed description
Age, sex, duration of disease, and equivalent daily dose of levodopa were assessed at baseline. From the beginning of the baseline phase to the end of the follow-up phase, patients were requested to complete an electronic bowel diary, which was supervised by an independent outcome assessor. The primary outcome in this study was the number of weekly CSBMs. Weekly CSBMs were collected at baseline (week 0), post-treatment (week 4), and follow-up (week 12), and differences from baseline levels were compared at week 4 and week 12. Anorectal manometry (AM) and colonic transit time (TT) were assessed in the two groups using standardized procedures. In brief, for TT evaluation, patients swallowed a capsule containing 24 radiopaque markers. Abdominal radiographs from patients in the erect posture were acquired 5 days after markers intake. During the test period, patients were instructed to maintain their habitual diet and to avoid laxatives, enema and suppositories. According to manufacturer's indications, the TT was described as "normal" if at least 19 markers (80%) were expelled at day 5. The AM was performed using the stationed pull-through technique, with a 4-channel water-perfused catheter linked to an electronic manometer. The catheter was inserted via the anal canal and positioned in the rectum, with the patient in a left-lateral decubitus position. Functional parameters included the resting and squeeze pressures, the ability of the anal sphincter to relax with straining, the recto-anal inhibitory reflex (RAIR) and the rectal sensation.
