Efficacy of pelvic floor muscle training in women with overactive bladder syndrome: a systematic review
- 38 Downloads
Introduction and hypothesis
Our objective was to evaluate the effectiveness of pelvic floor muscle training (PFMT) in reducing overactive bladder (OAB) symptoms in women.
Searches were performed at MEDLINE, PubMed, Physiotherapy Evidence Database (PEDro), Scielo, and Central Cochrane Library PubMed until January 2017. Controlled trials were researched by two independent reviewers. Eligible studies were restricted to random and controlled clinical trials that investigated the effectiveness of PFMT in decreasing OAB symptoms. Qualitative methodology was evaluated using the PEDro scale. Data was analyzed and interpreted qualitatively.
The final search retrieved eight studies (n = 1161 women with urgency symptoms), which were published between 2002 and 2016. The methodological scores varied between 4 and 7 in the PEDro scale. PFMT, with the objective of controlling urgent micturition, demonstrated improvements in quality of life in women with OAB. Most data in this revision came from small- to moderate-sized trials, with different and inconsistent outcome measures, which could have impacted the end results.
The literature regarding the effectiveness of PFMT in OAB remains heterogeneous and inconclusive.
