In this protocol, our team intend to conduct a nation-wide multicenter cohort research to screening for PFD symptoms in early postnatal women in China. Beside clinically significant symptoms, we will also measure the recovery trend of pelvic muscle function, aiming to determine the clinically significant alterations that are sensitive to predict the PFD risks. This is an observational prospective cohort study, following a natural regular clinical visit process. Patients will voluntarily decide whether to receive PFD related treatments and the types of treatments to adopt. Therefore, we will also be able to compare the effectiveness of treatments.
