Computational model of the left buttock of a patient with a spinal cord injury (SCI patient #5 in Linder‐Ganz et al. 13): (A) MRI slice (left frame) used to generate three‐dimensional model of the left buttock and its mesh (right frame) with three regions of interest (ROIs) defined in the anatomy. F, fat tissue, IT, ischial tuberosity, G, gluteus muscle. (B) Configurations of the finite element models with boundary and loading conditions for the different cushion conditions: foam (upper frame), off‐loading (OL) (mid frame) and air‐cell‐based (ACB) (lower frame) cushions.
