Prolonged mechanical loading of tissue in between a bony prominence and a support surface can lead to pressure ulcers. Despite recent initiatives to curb down incidence rates, the health care burden of pressure ulcer prevention remains significant . Etiology of pressure ulcers are commonly attributed to interface pressures. As a result, interventions, e.g., support surfaces, routinely aim to reduce contact pressures. However, the clinical effectiveness of such an objective can be questionable . Recent studies have shown that internal mechanics of the tissue can be associated with pressure ulcer development , potentially indicating the inefficacy of interventions targeted solely at contact pressure relief. Tissue characteristics at a bony prominence, e.g., tissue thickness and material properties, also influence load distribution within and on the surface of the tissue. Given the variability in patient populations and for a bony region of interest , it is possible that patient specific risk and load relief (with the use of support surface) may differ widely.
