The Comparison of Dynamic Balance in Males with Different Foot Types



The aim of this study was to compare the dynamic balance in men with different
foot types. A sample of 90 male students from University of Tehran including 30
subjects with normal foot type (mean height: 176.6±6.2 cm, mean weight:
72.8±10.2 kh, mean age 25.3±1.4 yr), 30 subjects with flat foot (mean height:
177.2±7 cm, mean weight: 73.5±11.1 kg, mean age: 25.1±1.4 yr), and 30 subjects
with pes cavus (mean height: 174.5±6.3 cm, mean weight: 69.3±11.3 kg, mean age:
25.6±1.7 yr) participated in this study. To determine the foot anatomic type,
navicular drop test was used. To assess subjects’ balance, SEBT was used. To
analyze the research data, MANOVA test was applied. The results showed a
significance difference in SEBT performance among groups. Linear coefficients
showed that medial and posterolateral reaches played a greater role in
differentiating the groups. Specifically, medial reach significantly played a role in
differentiating flat foot group and posterolateral reach in differentiating pes cavus
group from other groups. As those with pes cavus apply more pressure on lateral
margin of their foot, it seems that the stability domain is larger in lateral margin
while the reverse is true about those with flat foot. As a whole, it can be concluded
that foot anatomical characteristics influence dynamic balance.
