Abstract

Foot is the most distal segment in lower extremity chain and represents a relatively small base of support
upon which body maintains balance. There are three types of foot postures which are seen 1) Pes planus
2) Pes cavus 3) Neutral. So, it is likely that these deficits in foot posture may impair the foot function and
predispose to loss of balance.
Aim:- The aim of the study was to find the effect of Arch Index of foot on dynamic balance.
Method:-It was a cross sectional study on 175 healthy young individuals in the age group of 18-25yrs.
Individuals were assessed for Inclusion and Exclusion criteria. Arch index was calculated for both the
feet using foot prints with the help of software Auto Cad 2014. Dynamic balance was assessed using Star
Excursion Balance Test (SEBT) for both the feet. Normalised SEBT distances were calculated by dividing
reach distances in all eight directions by limb length.
Results:-. Arch index was found to be negatively correlated with normalised SEBT distances in Posterolateral
(r= -0.341,p= 0.01) and lateral(r= -0.369,p= 0.01) directions and positively correlated in Anterior(r=
0.296,p= 0.01),and medial (r= 0.296,p= 0.01)directions in pronated foot group. There was no correlation
found between Arch index and normalised SEBT distances in any direction for normal arched foot and
supinated foot group.
Conclusion:- Increased Arch Index (i.e. >0.26) implies pronated foot posture which affects dynamic balance
in Postero lateral and lateral directions of Star Excursion Balance Test (SEBT).
