ABSTRACT:
An improved foot pressure testing structure which comprises a test memory mold plate, a meshed plate and an evenly distributed convex moldboard being stacked with each other on a sole, such that when a patient wears the foot pressure testing structure and walks several steps (or for several minutes) for a test, the test memory mold plate is pressed due to the weight and pressure produced by the patient and the time accumulated in such walking activity, which causes the bottom of the test memory mold plate to be attached closely to and embedded deeply into the meshed plate and the moldboard to form a concave line. The length, depth, area of distribution, and variation of density of the concave line varies with different gaits, and such information can be used as a reference for medical or athletic evaluators to analyze the position and magnitude of the exerted force and the central line of the pressure along a traveling path to facilitate the medical assessment and production of a foot accessory such as a foot base and a pair of shoes. The foot pressure testing structure according to the invention has the features of simple structure, low cost, easy-to-operate, and visually inspecting the result without requiring any other additional measuring instruments.
