Abstract

The purpose of this study is to investigate the effect of functional shoe apparatus on bone density. To evaluate the usefulness of the flexcage apparatus inserted into the shoes, an appropriate impact force was applied to the feet. The model with the proposed structure had an effective stress of approximately 20–100% higher than that of the model without it, among most of 15 bone extraction points. Although the finite element analysis data from the human body model were not the values of mineral bone densities measured directly but those of the effective bone stresses against impact, the proposed structure was designed to increase the bone mass and improve the mineral bone density by actually improving the density of mineral bone. In conclusion, shoes with flexcage inserts were evaluated to improve the bone density compared with those without inserts.
