簡易足底壓力測試片之研究與開發

Abstract

The purpose of this study was to design an insole-style testing piece for a quick and easy dynamic foot pressure test. Current commercial foot pressure systems are costly and complicated to operate. These systems are not suitable for extensive evaluations of patient's foot or orthoses, either.The material used in this research is TPE-PS shock absorption foam. This foam has three special features: (1) excellent surface contact with foot contour, soft textures that do not irritate the foot, (2) creates permanent foot pressure imprints after brief walking, (3) the foam material does not crack or break under excessive foot pressure. When being assembled within the specially designed module for dynamic foot pressure testing, the test foam pieces exhibit the stamping effect from the foot pressure. The resulting foam pieces could show similar foot pressure distributions as compared to those from the ”print mat method”. The gait evaluation (foot pressure test) was designed to optimize the effectiveness of the foam within the module. This provided the best resulting foot pressure patterns for analysis and creation of a foot pressure distribution diagram. A correlation study between the data collected from a drop-weight test and pressure patterns on the foam was also conducted in order to quantify the pressure exerted on the foam. Data from the conducted experiments showed that the specially designed foam testing piece has the following advantages: (1) low cost-of-material and zero maintenance, (2) easy and quick operation, (3) test results can be read immediately by visual inspection, (4) the foam can also be used to evaluate the foot pressure distribution of custom insoles as a follow up service for patients.
