Effect of Flat Feet on Static and Dynamic Balance in Adults

Abstract

Background: The foot is the most distal segment in the lower extremity chain and represents a small
BOS upon which the body maintains balance. Minor biomechanical alterations in the support surface
can influence postural-control strategies. However, the implications of a flat foot on balance have
received little attention to date.Aimof the present study was to Evaluate the static and dynamic balance
in individuals with flat feet.
Method: A total of 40 subjects were recruited. Participants were assigned to 2 groups case group
and control group depending on foot type, as defined by the foot ink print method. Subjects were
divided into case groups and control groups. The static and dynamic balance were measured through
the Unipedal stance test and star excursion balance test respectively.
There was a significant correlation between single-leg stance time (with eyes opened and closed) and
flat feet (p-value = < .01). There was a significant correlation between reach distance in some direction
(AM, MR, PM, P, AL, LL) with a flat foot (p-value <0 .05).
Conclusion: This study suggests that both static (single leg stance test) and dynamic (SEBT) balance
are affected in individuals with flat feet.
