Pelvic floor (PF) dysfunctions comprise of a wide spectrum of interrelated clinical conditions and represent an important health problem. The PF supporting system can be regarded as a loaded structure with a complex geometry that supports the increase of abdominal pressure and maintain normal position of pelvic organs (Figure 1A). The weakening of the PF supporting system is considered to be the cause of these PF dysfunctions. Recently, scientists have tried to use the finite element (FE) method to calculate the stress distributions to improve the biomechanical understandings in such structure [1].The reliability of the material parameters of the PF muscles is crucial to the FE analysis. However, these material parameters are conventionally characterized through in vitro mechanical tests, which differ from those in the physiological or in vivo state. Therefore, people pay more attention to the in vivo biomechanical properties [2]. This paper develops a non-invasive inverse approach to identify the in vivo material parameters of the PF muscles. This approach tries to provide more realistic material parameters, thus may give more help to the numerical simula-
