Reliability of Prevention of Disability and Diagnostic Index of Spread Rate and Spread Angle for Spread Foot

Abstract

We propose a method that can be diagnosed in a simple spread foot to prevent failure in such as sports injuries. In addition, to clarify the boundary value that can be used to predict spread foot and its reliability, we report on our investigation of the effects of merger rate and location of pain and other diseases, using a 6-minute walk distance. Measurement of spread foot is measurement by using the spread angle and spread rate. We checked spread rate and the spread angle at the first and fifth metatarsal angles of the X-ray with correlation. And then we calculated by the regression equation metrics of spread foot. In the case of spread foot, to see the complications of other diseases, we observed the correlation high rate medial longitudinal arch, first toe angle and fifth toe angle. We also observed the merger rate of flatfoot deformity, hallux valgus deformity, and digitus quintus varus. We also examined the occurrence of pain and the occurrence of callus of spread foot.
