Validating Plantar Pressure Measurements from a Pressure-Sensing Orthotic Insole

Diabetic Neuropathy is a decrease of the perceptive ability of pressure changes and is a devastating consequence of

type two Diabetes. Neuropathy can result in ulcers, infection, amputation, and death. Providing alternative

feedback about pressure distributions in the foot is an innovative, low cost way to help reduce high level

pressures resulting in ulceration. In this study, we will calibrate a novel pressure sensing orthotic device for

accuracy in measurement compared to a gold standard pedobarograph. Three studies will be conducted to

evaluate the device’s ability to accurately quantify foot pressures. The first will be an exploration of diabetic

offloading patterns compared to a healthy population. The second study will calibrate the device against a gold

standard pedobarograph. Lastly, a study will be conducted to determine if visual feedback reduces the

frequency of high risk pressure profiles in a neuropathic population. This is the first crucial step to provide proof

of concept and is necessary for the continued development……………………………….
