简要总结
About 30% of women experience pain in the perineum and pelvic region one year after the vaginal labor, rising up to 50% when it is triggered during vaginal penetration, called this pain as dyspareunia. An early physiotherapy treatment could be the solution to the pain relief of these women. Thus, the objectives of the present randomised clinical trail are (i) to determine the effectiveness of a physiotherapy treatment based on education therapeutic, the treatment of myofascial pain syndrome (MPS) of the pelvic floor muscles (PFM), and PFM specific training with or without radiofrequency in reducing pain and improving sexual function; and, (ii) to know the facilitating factors and barriers in adherence and perceived self-efficacy towards physiotherapy treatment of women with pelviperineal pain in the postpartum.
Methodology: randomized clinical trial with examinator blinding and two parallel groups, followed by a qualitative study. Thirty eight women per group will be needed with postpartum pelviperineal pain between 8 weeks after labour, with intensity ≥ 4 cm on the visual analogue scale. The assignment will be random to an Experimental 1 group based on therapeutic education, plus conservative and invasive treatment of MPS and specific PFM exercise versus an Experimental 2 group consisted in the same treatment plus non-ablative radiofrequency treatment. In both cases, 12 individual supervised sessions will be held by a physiotherapist specialized in women's health, with evaluations pre- and post-intervention, at 3 and 6 months. The outcome variables will be the intensity of the pain, the presence of MPS at PFM, the PFM contraction quality, sexual function and specific quality of life. The qualitative study will be carried out in the assessment 6 months post-intervention, through interviews semi-structured and focus groups. The interviews will be guided with previous questions established, recorded, transcribed and thematically analyzed by a panel of experts.

结局指标
主要结局
Pain intensity through the Verbal Numerical Scale (0 no pain, and 10 the most bearable pain)
时间窗: Pre-treatment, post-treatment (6 weeks after starting the study), 3 and 6 months after treatment
intensity, behavior and location (pain body chart).
Sexual function
时间窗: Pre-treatment, post-treatment (6 weeks after starting the study), 3 and 6 months after treatment
