Pressure Ulcers (PU) are soft tissue injuries that may occur when high and extended loads are applied to the tissues. The onset of PU has been mechanically explained by excessive shear strains [1]. When the unloading of the tissues is not possible, medical devices such as dressings can be applied to temporally relieve the tissues. However, there is little evidence showing the mechanical efficacy of these dressings to decrease the strains around PU. This study presents a Finite Element (FE) analysis of such efficacy on an asymptomatic heel and injured heels, with two different stages of PU.
