The Foot Posture Index (FPI-6)

The FPI-6 is a novel method of rating foot posture using set criteria and a simple scale.

Redmond's FPI is intended to overcome some of the shortcomings (poor reliability and validity) with existing clinical measures of foot posture. It is a measure of standing foot posture and so is not a replacement for gait assessment where time and facilities exist. It is however a more valid approach than many of the static weightbearing and non-weightbearing goniometric measures currently used in clinic.

The FPI has been subjected to a thorough validation process details of which can be found in:
Redmond AC., Crosbie J., Ouvrier RA. Development and validation of a novel rating system for scoring foot posture: the Foot Posture Index. Clinical Biomechanics 2006, 21:1; 89-98 or as a PDF downloadable directly here.

The FPI-6 has been validated against the Rasch statistical model:
Keenan AM, Redmond AC, Horton M, Conaghan PC, Tennant A. The Foot Posture Index: Rasch analysis of a novel, foot specific outcome measure. Archives of Physical Medicine and Rehabilitation 2007, 88:1; 88-92.

And a data sets of normative blues has been published as:
