Redmond et al developed the Foot Posture Index (FPI) to determine the pronation or supination of the foot in a person who is standing. The authors are from the University of Leeds.
The index consists of an evaluation of 8 findings.
|
Examination |
Pronation |
Supination |
|
prominence in the region of the talonavicular joint |
bulging |
indentation |
|
position of the calcaneal frontal plane |
everted |
inverted |
|
Helbing's sign (bowing of the Achilles tendon) |
inferior part directed to the lateral side |
inferior part directed to the medial side |
|
supra and infra-lateral malleolar curvature |
curve below the malleolus is more acute than the curve above |
curve above the malleolus is more acute than the curve below |
|
congruence of the lateral border of the foot |
concave |
convex |
|
palpation of the talar head |
more prominent on the medial side |
more prominent on the lateral side |
|
congruence of the medial longitudinal arch |
proximal part lowered |
proximal part elevated |
|
abduction or adduction of the forefoot relative to the rear foot |
forefoot abducts |
forefoot adducts |
|
Scoring |
Points |

|
mild to moderate supination |

total index =
= SUM(points for all 8 findings)
Interpretation:
• minimum score: -16
• maximum score: +16
• The higher the score the greater the pronation.
• The lower the score the greater the supination.
