Guidelines for Selecting the Appropriate Heel Insert for Long-Standing Ladies

Authors: Atisthan Wuttimanop, Suchada Rianmora, Mahint Mahattanakorn

Abstract:

Feet and ankles are parts of human body that receive high-pressure in every day. Feet disorders such as ankle sprain, achilles tendonitis, heel pain, and plantar fasciitis are very common. There are many causes for these feet disorders such as wearing high heels, obesity, sports activity, and standing for a long time. There are many reliefs for feet disorders such as heel insert. However, they come in various shapes and use different materials. There are no specifications in which type is suitable for specific user. This has led to the proposed research to provide guidelines for selecting the appropriate heel insert for ladies who face with long-standing carriers. This research uses contact-measuring techniques to test forces, contact area, and pressure acting on a person’s feet in various standing positions with different insert materials and shapes. The proper material for making insert will be presented and discussed.

Keywords: Heel inserts, Long-standing person, Contact-data acquisition, Finite element analysis, Ethylene-vinyl acetate (EVA).
