ABSTRACT

Introduction: There are various methods used to assess flat foot in the individuals. Foot posture index-6 (FPI-6) is a qualitative as well as a quantitative tool for assessing flat foot. Chippaux- Smirak index (CSI) is a quantitative method that can be calculated using the ink foot prints. Both of them are reliable methods but foot posture index is very commonly used. Thus, there arises a need to replace foot posture index with a new tool which is purely quantitative. Purpose: To establish concurrent validity between CSI and FPI-6 in asymptomatic flatfoot individuals. Methods: A total of 140 participants of Parul university, Vadodara, Gujarat between the age group of 18-25yrs with no history of pain or injury within last one year were assessed for asymptomatic flexible flatfoot. The CSI and FPI-6 were used to evaluate all individuals for asymptomatic flat foot. Participants were characterised as having flat foot if their CSI and FPI- 6 score were equal to or greater than 45% and 6+ to 12+ respectively. Results: The CSI and the FPI-6 have a Spearman rho correlation value of 0.62 (p<0.05) indicating a moderate positive correlation among the two indices. Conclusion: As there is a moderate positive correlation of CSI with FPI-6, it can be used to assess the foot posture in asymptomatic flat foot individuals.
