To design and implement a rehabilitation program based on pelvic floor muscle training (PFMT) to improve the urinary incontinence (UI). Methods: This study is based on a randomized clinical trial. The sample was formed by 66 participants with prostate cancer. The intervention groups were randomized into an experimental group (EG) and a control group (CG). The variables studied are: waist perimeter, variables related to the evolution of UI, muscular strength, and quality of life (QoL). Measurements were taken in order to evaluate changes in both groups. A statistical analysis was conducted using the Student–Fisher t-test, the Mann–Whitney–Wilcoxon test, and the chi-square test. Findings/Conclusions: After 24 weeks an improvement was identified in the EG compared with the CG, in waist perimeter (p .001), variables related to the UI symptom, intensity, frequency, difficulty and limitation of activity (p .0001). A correlation between UI and QoL was observed (p=.039). Clinical relevance: The improvement in QoL is mediated indirectly by the improvement in the UI symptom.
