AbstractHuman foot posture is highly variable among healthy individuals and ranges from flat- to higharched. The Foot Posture Index (FPI) is a validated method for quantifying standing foot posture, and is being used in a variety of clinical settings. Therefore objective of the study was to find correlation between Foot Posture Index-6 (FPI-6) and Navicular Drop Test (NDT) with functional Ankle Stability in Running Male Athletes. 60 Male Running athletes participated in the study. Foot Posture Index- 6, Navicular Drop Test, Side Hop Test were performed by them and data was recorded. Correlation between them was determined by Pearson correlation coefficient. Functional Ankle Stability using side hop test were calculated of both the feet and correlation with FPI & NDT. Results showed that there is significant correlation between the foot posture index - 6, Navicular Drop Test and Side Hop Test for ankle stability. Hence it was concluded that the ankle instability is correlated with foot posture & navicular drop in healthy running athletes.
