The FPI-6 is a novel method of rating foot posture using set criteria and a simple scale. It is a clinical tool used to quantify the degree to which a foot is pronated, neutral or supinated. 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-6 is a novel method of rating foot posture using set criteria and a simple scale.

Objective
[edit | edit source]
The FPI-6 is a novel method of rating foot posture using set criteria and a simple scale. It is a clinical tool used to quantify the degree to which a foot is pronated, neutral or supinated. 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.
Intended Population[edit | edit source]
Method of Use[edit | edit source]
The patient should stand in their relaxed stance position with double limb support. The patient should be instructed to stand still, with their arms by the side and looking straight ahead. It may be helpful to ask the patient to take several steps, marching on the spot, prior to settling into a comfortable stance position. During the assessment, it is important to ensure that the patient does not swivel to try to see what is happening for themself, as this will significantly affect the foot posture. The patient will need to stand still for approximately two minutes in total in order for the assessment to be conducted. The assessor needs to be able to move around the patient during the assessment and to have uninterrupted access to the posterior aspect of the leg and foot. If an observation cannot be made (e.g. because of soft tissue swelling) simply miss it out and indicate on the datasheet that the item was not scored. If there is genuine doubt about how high or low to score an item always use the more conservative score.

|---|---|---|---|---|---|
| Talar head palpation | Talar head palpable on lateral side/but not on medial side | Talar head palpable on lateral/slightly palpable on medial side | Talar head equally palpable on lateral and medial side | Talar head slightly palpable on lateral side/palpable on medial side | Talar head not palpable on lateral side/but palpable on medial side |

Supra and infra lateral malleoli curvature (viewed from behind) |
Curve below the malleolus either straight or convex | Curve below the malleolus concave, but flatter/more than the curve above the malleolus | Both infra and supra malleolar curves roughly equal | Curve below the malleolus more concave than curve above malleolus | Curve below the malleolus markedly more concave than curve above malleolus |
| Calcaneal frontal plane position (viewed from behind) | More than an estimated 5o inverted (varus) | Between vertical and an estimated 5o inverted (varus) | Vertical | Between vertical and an estimated 5o everted (valgus) | More than an estimated 5o everted (valgus) |
| Prominence in region of TNJ (viewed at an angle from inside | Area of TNJ markedly concave | Area of TNJ slightly, but definitely concave | Area of TNJ flat | Area of TNJ bulging slightly | Area of TNJ bulging markedly |
| Congruence of medial longitudinal arch (viewed from inside) | Arch high and acutely angled towards the posterior end of the medial arch | Arch moderately high and slightly acute posteriorly | Arch height normal and concentrically curved | Arch lowered with some flattening in the central position | Arch very low with severe flattening in the central portion - arch making ground contact |
| Abduction/adduction of forefoot on rearfoot (view from behind) | No lateral toes visible. Medial toes clearly visible | Medial toes clearly more visible than lateral | Medial and lateral toes equally visible | Lateral toes clearly more visible than medial | No medial toes visible. Lateral toes clearly visible. |
Evidence[edit | edit source]
Menz H (1998). Alternative techniques for the clinical assessment of foot posture. JAPMA; 88(3):119-129
Evans A et al (2003). Reliability of the foot posture index and traditional measures of foot position. JAPMA; 93(3): 203-213
Reliability[edit | edit source]
The FPI-6 is a quick, simple and reliable clinical tool which has demonstrated good inter-rater reliability when used in the assessment of the paediatric foot[1].
Validity[edit | edit source]
The FPI-6 has been subjected to evaluation against the Rasch statistical model. This analysis confirms the construct validity of the six-item instrument and the linearity of the metric output[2].
Responsiveness[edit | edit source]
