Abstract

In this paper, we proposed a new method to measure the C-curve angle of a toenail to evaluate an ingrowing toenail, and analyzed the measured angle of C-curve of toenail to find the related variables, such as, self-judged angle, presence of an ingrowing toenail, walking style, type of shoes, height of heel, the experience of foot care, education and occupation. Basically, in the study of ingrowing toenail, it is important for the C-curve angle of toenail to be a tool of measuring the degree of refraction of toenail, and of evaluating an ingrowing toenail. The survey was performed with questionnaires and the picture of the toenail of respondents were taken. The data from 197 respondents who are female students or female customers of the nailcare shop were analyzed by frequencies, t-test, and F-test (ANOVA). The results of this study were as follows. First, the measured angle of C-curve is very important to study the evaluation of an ingrowing toenail. Second, it is more fit to study the ingrowing toenail than the self-judged angle. Third, it is differed by the presence of an ingrowing toenail. Four, it is differed among the position of the center of mass during walking. Five, it is narrowed in the case of high hill typed footgear. Six, it is narrowed for the group not taken footcare.

Key Words: Ingrowing toenail, C-Curve angle of toenail, Self-judged angle, Walking style, A pain of a toenail
