Abstract
Disclosed herein is a device for repeatably and accurately measuring the threshold sensitivity of the skin on a body part or surface such as the plantar surface of the foot. The machine uses a monofilament pressure test, where a monofilament is applied to the surface of the skin until it buckles at a corresponding force. The device may measure a broad range of pressures and responsive sensation in the patient using multiple applications of the monofilament. The patient indicates a positive or negative response, based on whether the patient sensed the monofilament pressure. The machine may include a foot clamping assembly, a support chassis, a linear motion translation assembly for locating the monofilament at a given position for testing, and a camera for taking images used to identify testing locations and report results. Methods of use and testing protocols are also described herein.
