Development of an evaluation system for foot arch types in the elderly using foot pressure distribution data.
The foot arch serves important functions related to shock absorption and the action of walking. Simple and quantitative classifications of foot arch types, such as flat feet and high arches, help to provide health support services for the elderly. To develop an evaluation system for foot arch types using foot pressure distribution data, discriminant analyses were conducted using data from healthy elderly persons. The midfoot pressure ratio was selected and discriminants were derived. For evaluating the performance of the classification method, the derived discriminants were applied to the data from the other group of healthy elderly persons. Results indicate that both sensitivity and specificity of the classified foot arch types were sufficiently high.
