Abstract

Introduction and hypothesis Female myofascial pain (MFP) of the pelvic floor muscles (PFM) is a subtype of chronic pelvic pain associated with urinary, anorectal, and sexual symptoms, such as dyspareunia. Treatment remains poorly discussed, and we hypothesized that different treatments could improve outcomes versus placebo or no treatment. Methods A systematic review (CRD 42020201419) was performed in June 2020 using the following databases: PubMed, Cochrane Library, Web of Science, Embase, Scopus, BVSalud, , and PEDro, including randomized clinical trials related to MPF of PFM. Primary outcome was pain after treatment, and secondary outcomes were quality of life and sexual function. Risk of bias and quality of evidence (GRADE criteria) were evaluated. Meta-analysis for continuous variables was performed (mean difference between baseline and treatment and post-treatment mean between groups). Results Five studies were included (n = 218). Final mean VAS score (GRADE: very low) after 4 weeks of treatment (p = 0.14) and the mean difference from baseline and 4 weeks (p = 0.66) between groups were not different between the intervention and control groups. Quality of life according to the SF-12 questionnaire (GRADE: very low) followed the same pattern. However, sexual function (GRADE: low) according to the total FSFI score (MD = -5.07 [-8.31, -1.84], p < 0.01, i(2) = 0%) and the arousal, orgasm, and pain domains improved in the intervention groups when the mean difference from baseline and 4 weeks was compared with controls. Conclusion Pain and quality of life after 4 weeks of heterogeneous intervention differed between the intervention and control groups in sexual function: FSFI in studies improved in almost all domains. VAS (in three studies) and SF-12 (in two studies) failed to demonstrate differences. (AU)
