Abstract
This invention relates generally to an index map comprising both pressure and perfusion information from a diabetic patient foot for the purpose of treatment. The index map may also be a map of perfusion and/or metabolism of the tissue (reflecting oxygen delivery and oxygen extraction, obtained by thermal imaging, hyperspectral imaging, or duplex ultrasound, MRA, CT or laser Doppler imaging. This information aids treatment in prevention of diabetic foot ulceration and amputation and in treatment of tissue compromise to prevent tissue loss in other body regions.

1-57. (canceled)
A method for designing a prosthetic or orthotic device for treatment of a tissue of a subject, the method comprising:
- (A) obtaining a gradient map of the tissue of the subject, wherein the gradient map comprises information about tissue oxygenation, tissue oxygen extraction, tissue metabolism, or tissue perfusion of the tissue;
- (B) determining a pressure or stress applied to the tissue;
- (C) identifying one or more areas of the tissue that are at risk for disease formation or disease progression based on the gradient map, or the pressure or stress applied to the tissue;
- and
- (D) designing the prosthetic or orthotic device to redistribute the pressure or stress across the tissue, wherein the redistribution of the pressure or stress across the tissue reduces the pressure or the stress applied to the one or more identified areas of the tissue that are at risk for disease formation or disease progression.
