This study will be conducted with the approval obtained from the Institutional Review Board (IRB) of MacKay Memorial Hospital. This parallel-two-group randomized experimental study including an experimental group and a control group examines the effects of pelvic floor muscle training (PFMT) combined with yoga on genitourinary symptoms, symptom-related quality of life, and sexual function. A sample of women with breast cancer experiencing ≥1 genitourinary symptom(s) will be recruited and assigned to an experimental group or a control group by using the block randomization method. The experimental group will receive regular care and a 12-week program of PFMT and yoga. We will provide the experimental group with 12 days of online group practice sections of PFMT and yoga (weekly 60-minute practice incudes yoga 40 minutes, PFMT 15 minutes, and reflection 5 minutes). We expect them to perform 36 days of home-based practice of PFMT and yoga with 3 days/week of yoga for 40 minutes and PFMT for 15 minutes. The control group will receive regular care and relevant educational materials after data collection. Information will be collected at five time points: baseline and 4, 8, 12, and 24 weeks after baseline. Generalized estimating equation procedures will be used to examine the effects of the intervention. We hypothesized that the experimental group will display more significant improvements in genitourinary symptoms, symptom-related influences, and sexual function than those shown in the control group.
