Considering that physical activity provides important benefits to minimize the physical and emotional impact of the treatment, the Pilates Method is a modality of physical exercises that could increase the quality of life parameters of women survivors of breast cancer. Objective: To study the impact of Pilates Method on pelvic floor muscle (PFMS) strength, sexual function (SF), and health related quality of life related (HRQL) of BC survivors. Method: Randomized clinical trial in which 24 mastectomized women were divided into two groups: Pilates (G1) and control group (G2) exercises for 8 weeks. SF was assessed by the FSFI questionnaire and HRQV by the EORTC QLQ-C30 questionnaire. PFMS was assessed by perineometry and contractility using the PERFECT scheme. Values are expressed as mean ± standard deviation. Inferential analysis was performed using repeated measures ANOVA and Bonferroni post-test. Results: Women of the G1 showed better performance than those of the G2 for the following variables: sexual function, degree of muscle contraction; all items of the PERFECT scheme; QLQ-C30 questionnaire domains: global health status, physical functioning, emotional functioning; symptom scale items fatigue, nausea, and pain, and perception of financial difficulties (p < 0.05). Conclusion: The results show benefits of supervised Pilates exercises on pelvic floor muscle contractility, sexual function, and quality of life after cancer.
