FE Evaluation: Application of the Buttock-Thigh FE Model

Investigation Soft Tissue Response in WO-BPS posture vs. in Normal Posture using Established FE Model

1. Interface pressure in two sitting postures was recorded.

Soft Tissue Response in Different Sitting Postures by FE Model

2. Actual recordings of the interface pressure in two  sitting postures were applied to the FE model, together with muscle tone and skin tension.

Displacement  on the skin Focused on the anterior-posterior displacement in six mediolateral sections

Finding: The location of highest displacement is moved from buttock to thigh region with a reduction of displacement

Deformation of muscle below IT bone

Finding: The location of highest deformation is moved from ITto thigh region with a reduction of deformation magnitude.

                                                    Von Mises stress Distribution in the muscle group 1

Finding: Maximum pressure region is moved from buttock to thigh region for WO-BPS with reduction of von Mises stress magnitude.
