EFFECT OF PHOTOBIOMODULATION ON CHRONIC PELVIC PAIN IN WOMEN OF REPRODUCTIVE AGE: PROTOCOL FOR A RANDOMIZED CLINICAL TRIAL
Physical therapy. Pelvic pain. Photobiomodulation.
Introduction: Chronic pelvic pain (CPP) is a multifactorial and highly prevalent condition among women of reproductive age, frequently associated with gynecological, urological, gastrointestinal, musculoskeletal, and psychological causes. This condition negatively impacts functionality, quality of life, sexual function, and pelvic floor muscle (PFM) function, and represents a therapeutic challenge due to its complexity and limited response to conventional treatments. In this context, photobiomodulation (PBM) has emerged as a safe, non-invasive therapeutic approach with analgesic and anti-inflammatory potential. Objectives: To evaluate the effects of PBM on CPP in women of reproductive age and, secondarily, to investigate its effects on quality of life, functionality, sexual function, and PFM function. Methodology: This is a randomized, double-blind, placebo-controlled clinical trial with 30 participants distributed between an experimental group (active PBM) and a control group (placebo PBM). The intervention will be performed
using the FLUENCE MAXX® device (HTM), using red LED (660 nm), continuous mode, dose of 3.0 J/cm² and application time of 54 seconds, according to the guidelines of the World Association for Photobiomodulation Therapy (WALT). The protocol will comprise 12 sessions (once a week, for 12 weeks). Validated instruments will be used to measure the outcomes: Brief Pain Inventory (BPI), WHOQOL-BREF, WHODAS 2.0, Female Sexual Function Index (FSFI) and the New Perfect. Assessments will occur before, during (6 weeks) and after the intervention (12 weeks). Data will be analyzed using IBM SPSS Statistics 21.0 software, using descriptive and inferential statistics (ANOVA and Generalized Linear Models), considering a significance level of p < 0.05. Expected Results: FBM is expected to significantly reduce the intensity of CPD and promote improvements in quality of life, functionality, sexual
function, and pelvic floor muscle function in women with CPD.
