Urinary incontinence (UI) is a prevalent issue among women, affecting their quality of life and daily functionality. Pelvic floor muscle training (PFMT) is an effective strategy for managing UI, and mobile technologies have emerged as an alternative to improve treatment adherence.

This study analyzed the effects of using a mobile application for pelvic floor muscle training in women with stress and mixed urinary incontinence, focusing on adherence, perceived health improvement, and impact on activities of daily living.

This randomized controlled trial followed CONSORT guidelines and included 52 women diagnosed with stress or mixed urinary incontinence, who used a mobile application for pelvic floor training. The intervention lasted 12 weeks, with pre- and post-intervention assessments using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) and King’s Health Questionnaire (KHQ). Adherence was monitored, and the impact on ADLs and quality of life was analyzed. The data were analyzed by intention to treat. The collected data were tabulated in a database of the EXCEL® program and analyzed using the SPSS statistical software (Statistical Package for the Social Sciences). A descriptive analysis of the data was performed, using simple frequency, mean, standard deviation, p-value, and effect size (D of Cohen) of the quantitative data.The normality of the data was verified using the Shapiro Wilk test. For the analysis of the data, the Two-way ANOVA test with Tukey post-hoc was used. A level significance of 5% was considered.

Participants using the mobile application reported a significant improvement in general health perception (p = 0.009) and a reduction in the interference of UI in daily activities (p = 0.045). However, adherence to the training protocol was low, with an average of 39.59% of the proposed training days completed. Despite this, 84.61% of participants rated the intervention as “excellent.” Improvements in emotional well-being and self-reported quality of life were observed, but limitations in social engagement remained largely unchanged.

Findings suggest that the mobile application was effective in improving perceived health and reducing UI interference in daily life, despite lower adherence rates.

Mobile applications can be a promising tool for PFMT, especially in promoting self-management. However, strategies to enhance adherence, such as reminders, gamification, or remote professional support, should be considered in future research to maximize treatment benefits.
