Efficacy of educational instructions on pelvic floor muscle training in the treatment of urinary incontinence: Systematic review and meta-analysis

Objective: The present study aimed to investigate the efficacy of educational interventions on pelvic floor (PF) muscle training in the treatment of urinary incontinence (UI).Methods: This is a systematic review of literature with meta-analysis, performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). To do so, randomized clinical trials that performed educational interventions of PF, UI, and developed the training of PF muscles (TPFM) for incontinent women, performing group or individual comparisons, with control and experimental groups or with two or more experimental groups were selected. The search for papers was performed in the following databases: PubMed, Scopus, Embase, Web of Science, and SciELO, no specific publication date was chosen. The risk of bias was performed using the PEDro scale and the quality of the evidence was performed using GRADE.Results: The review included six studies with 1003 participants. Most studies presented 5-8 points regarding risk of bias. Most of the studies were performed in the last 5 years, with women of various ages, high educational level and prevalence of UI of effort. The present study showed that offering educational instructions and guiding women on TPFM was capable of reducing urinary symptoms. When compared to control, significant between-group differences were found in the studies, in which the control group did not receive any kind of instructions or treatment (p < 0.05). The use of technologies through mobile apps was efficient in the treatment of incontinent women (p < 0.05). Performing TPFM individually or in groups did not present differences in the results, with both improving urinary symptoms. The meta-analysis presented a mean effect and a clinically important difference in three studies.Conclusion: The interventions involving instructions to TPFM associated to health education brought improvements to urinary symptoms.
