Abstract

The purpose of this study is to analyze the differences in foot type of female college students according to academic major in both feet. The subjects for this study were 216 female students who took liberal arts classes in Seoul. Dependent variables were students' field of study -specifically whether or not they majored in physical education. Analysis of students' foot type and Malalignment Syndrome were measured using Resting Calcaneous Stance Position (RCSP). There were five categories for RCSP angle: Severe Pes Planus (< $-5^{\circ}$), Pes Planus ($-3^{\circ}{\sim}-4^{\circ}$), Pes Rectus (${\pm}2^{\circ}$), Pes Cavus ($+3^{\circ}{\sim}+4^{\circ}$), Severe Pes Cavus (> $+5^{\circ}$). ${\chi}^2$ analysis was used for statistical analysis. RCSP for all subjects (432 feet) occurred at the following frequency: Pes Planus(43.9%), Pes Rectus(43.8%), and Pes Cavus(12.3%). These levels were different for physical education majors, with Pes Planus at 42.6%, Pes Rectus at 49.4%, and Pes Cavusat 8.0%. Non-physical education majors exhibited Pes Planus at 45.0%, Pes Rectus at 39.9%, and Pes Cavus at 15.1%. 15.3% (33 subjects) of all students had Malalignment Syndrome. In conclusion, 56.2% of female college students had a foot deformity. There was nearly four times more Pes Planus than Pes Cavus. According to these results, exercise can be prescribed to alleviate foot deformities, especially supination. Severe pronation and supination problems appeared less amongst students not majoring in physical education. Thus, although exercise might be one cause of foot deformity, it can also help resolve problems with over-supination. Further study will be needed to understand and resolve the specific mechanism of over-supination.
