چکیده انگلیسی
The objective of this study was to measure and model the passive biomechanics of cadaveric levator ani muscle in the fiber direction at low strains with a moderately slow deformation rate. Nine levator ani samples, extracted from female cadavers aged 64 to 96 years, underwent preconditioning and uniaxial biomechanical analysis on a tensile testing apparatus after the original width, thickness, and length were measured. The load extension data and measured dimensions were used to calculate stress-strain curves for each sample. The resulting stress-strain curves up to 10% strain were fit to four different constitutive models to determine which model was most appropriate for the data. A power-law model with two parameters was found to fit the data most accurately. Constitutive parameters did not correlate significantly with age in this study; this may be because all of the cadavers were postmenopausal.
