Some of the studies we discuss in our eJournal Club refer to the Foot Posture Index(1, 2). The Foot Posture Index consists of six specific criteria:
Each Foot Posture Index criterion is scored by an examiner on a 5-point scale ranging from -2 (very supinated) to +2 (very pronated)
- Palpation of the talar head
- Supralateral and infralateral malleolar curvature
- Calcaneal frontal plane position
- TN joint prominence
- Abduction and adduction of the forefoot on the rearfoot.
- Congruence of the longitudinal medial arch
Scores are then summed to give an overall foot posture score. The summed score has the potential to range from –12 (highly supinated) to +12 (highly pronated).(1, 2)
To increase accuracy multiple examiners can be used and the totals averaged.
Studies(1, 2, 3, 4) indicate that the clinical measurement of Foot Posture Index has moderate-to-high reliability when assessing adult populations.
