TABLE 4.
Comparison of simulated soft tissue thicknesses (mm) under the ischial tuberosity before (T_preload) and after loading (T_loaded) for the four seat conditions. The simulations with (Y) and without (N) considering tissue sliding are compared. The average tissue thicknesses were calculated in two ROIs defined in Figure 5.
