Efficacy of Physiotherapy for Treating Vulvodynia: A Systematic Review.

Objectives: We set out to assess the efficacy of physiotherapy for vulvodynia.

Materials and methods: PubMed, Embase, Scopus, Web of Science, SciELO, PEDro, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched in February 2023. Two authors selected and extracted the data independently. The risk of bias was assessed using the Cochrane Risk of Bias tool (Rob 2). Because of the high heterogeneity presented between the studies, it was not possible to carry out qualitative analysis. The results were presented narratively. This systematic review was registered with the PROSPERO database.

Results: A total of 2,274 articles were retrieved. Seven studies met the criteria and were included in a systematic review, which included a total of 477 patients. The interventions included were electromyography biofeedback ( n = 2), transcutaneous electrical nerve stimulation ( n = 1), transcranial direct current stimulation ( n = 1), low-intensity shockwave ( n = 1), physiotherapy treatment ( n = 1), and pelvic floor exercise with behavioral modification ( n = 1). All studies evaluated pain reduction, 5 evaluated sexual function, and 2 evaluated quality of life. All interventions were effective for the main outcomes; only the transcranial direct current stimulation intervention showed no significant difference when compared with the placebo or sham group. Three studies presented a high risk of bias due to the lack of blinding.

Conclusions: The studied interventions (electromyography biofeedback, transcutaneous electrical nerve stimulation, shockwave, physiotherapy, and pelvic floor exercise) seem to improve pain, sexual function, and quality of life. However, the heterogeneity of the studies prevented meta-analysis. In addition, well-designed trials are needed to improve the certainty of this evidence.
