Effect of perineal self-acupressure on constipation: a randomized controlled trial.

Abstract

The efficacy of perineal self-acupressure in treating constipation is uncertain. We aimed to evaluate whether perineal self-acupressure would improve patient reports of quality of life and bowel function at 4 weeks after training. A randomized, parallel group trial was conducted. The study took place at the UCLA Department of Medicine. One hundred adult patients who met Rome III criteria for functional constipation participated. The control group received information about standard constipation treatment options, while the treatment group received training in perineal self-acupressure plus standard treatment options. Primary outcome was the Patient Assessment of Constipation Quality of Life (PAC-QOL). Secondary outcomes included patient assessments of bowel function (as measured by a modified Bowel Function Index (BFI)), and health and well-being (as measured by the SF-12v2). The mean PAC-QOL was improved by 0.76 in the treatment group and by 0.17 in the control group (treatment-effect difference, 0.59 [95 % CI, 0.37 to 0.81]; p < 0.01). The mean modified BFI was improved by 18.1 in the treatment group and by 4.2 in the control group (treatment-effect difference, 13.8 [95 % CI, 5.1 to 22.5]; p < 0.01). The mean SF-12v2 Physical Component Score was improved by 2.69 in the treatment group and reduced by 0.36 in the control group (treatment-effect difference, 3.05, [95 % CI, 0.85 to 5.25]; p < 0.01); and the mean SF-12v2 Mental Component Score was improved by 3.12 in the treatment group and improved by 0.30 in the control group (treatment-effect difference, 2.82, [95 % CI, -0.10 to 5.74]; p < 0.07). The trial was not blinded. Among patients with constipation, perineal self-acupressure improves self-reported assessments of quality of life, bowel function, and health and well-being relative to providing standard constipation treatment options alone.
