Comparison of mean contact area (CA), average pressure (AP), and peak pressure (PP) on the ischial area (ICA, IAP, and IPP) across four different modes, which include back reclined mode (BRM), lumbar support with back reclined mode (LBM), femur upward with back reclined mode (FBM), and lumbar support with femur upward with back reclined mode (LFBM). Values are mean ± standard deviation (N = 16)
P is given for statistical significance
