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:
Redmond AC., Crane Y.Z., Menz H.B. Normative values for the foot posture index. BioMed Central, Journal of Foot and Ankle Research 2008, 1:6 1-9.

The FPI datasheets have been released into the public domain and various datasheets, reference sheets and manuals are available for download from this site. For first time users we recommend that you download the full datasheet and the manual in PDF format. A set of datasheets with a handy reference sheet on the reverse are also available here, along with a JPG (image) version for incorporating into customised clinic notes.
