Myofascial pelvic floor pain (MPFP) significantly impacts women's quality of life, affecting physical, emotional, and social aspects. Photobiomodulation (PBM) has emerged as a promising therapy for managing this condition. However, treatment adherence may be a critical factor for therapeutic success.

To investigate adherence to PBM treatment in women with MPFP.

A cross-sectional observational study, derived from a feasibility study for a randomized clinical trial, was conducted with 21 women aged 18 years or older diagnosed with myofascial pelvic floor pain (MPFP). Participants were divided into three groups receiving different PBM dosages: G1 (1J), G2 (4J), and G3 (6J), over eight intervention days, twice a week. Treatment adherence was assessed based on attendance frequency, with adequate adherence defined as attending at least 80% of the sessions. Education level was categorized into incomplete high school and high school or higher. Sociodemographic data, including education level, were collected using a standardized form.

Treatment adherence rates were 100% in the 1J group, 88% in the 4J group, and 100% in the 6J group, with no statistically significant differences between groups (p = 0.098). Regarding education level distribution in G2, 72.4% of participants had only incomplete high school education, while the other groups had a higher proportion of women with high school or higher education (85.7% in G1 and 71.4% in G3).

The results suggest that education level may have a tendency to influence treatment adherence. Strategies to improve adherence, especially among women with lower education levels, should be considered in future studies.

The findings suggest that education level may tend to influence adherence to PBM treatment in women with MPFP. Although not statistically significant, this trend highlights the need for personalized strategies, such as clear guidance and continuous support, particularly for women with lower education levels. The study reinforces the importance of considering sociodemographic factors in managing treatment adherence.
