The Impact of Breathing Training on PPSUI: A Randomized Controlled Trial

\*\*Clinical Trial\*\* This clinical trial aims to investigate the clinical therapeutic effects of breathing training on postpartum stress urinary incontinence (PPSUI). Participants will: All participants will receive standard postpartum care and recovery guidance, including routine examinations, health counseling, basic postpartum recovery recommendations, and educational information. Control Group: Participants will receive conventional pelvic floor rehabilitation therapy, which may include one or a combination of the following: magnetic stimulation therapy, electromyographic biofeedback therapy, and manual therapy. The specific treatment methods and frequency will be determined based on individual patient conditions. Intervention Group: In addition to the same pelvic floor rehabilitation therapy as the control group, participants will receive breathing training. Before each session, participants will empty their bladder. The breathing training will be conducted under researcher supervision and guidance, with each session lasting 20 minutes, administered once daily, three times per week for 6 weeks. Participants are encouraged to perform the training in the hospital under researcher supervision. Those unable to attend in-person sessions may conduct home-based training after mastering the technique and must report their training status to researchers afterward. Researchers will monitor weekly training completion and provide timely reminders to ensure adherence. If dizziness or difficulty breathing occurs during training, participants must immediately discontinue the session.
