Normal Values of the Foot Posture Index in a Young Adult Spanish Population

Abstract

The normal FPI range goes from just one point of supination to a certain degree of pronation (+6). The identification of 35 individuals with potentially pathologic feet may help in the implementation of a preventive plan to avoid the appearance of foot disorders.

Evaluation of the paediatric foot using footprints and foot posture index: A cross‐sectional study

“…The FPI values obtained in our sample were 4.3 for the girls and 4.6 for the boys, half a point higher than those reported by Gijon et al . (mean 3.83), Evans et al .…”

“…The FPI values obtained in our sample were 4.3 for the girls and 4.6 for the boys, half a point higher than those reported by Gijon et al 21 30 using the same type of foot (normal or rectus foot sample). Conversely, the footprint values for our sample (mean 31.9) were lower than those observed by Forriol, 31 (mean 40.8 girls, 36.0 boys), although they were similar to the findings of Echarri 32 (mean 30.6) and had the same problem in a sample of only 5% cavus feet (same age range).…”

“…12 Inter-observer reliability for the FPI has been determined to be good (intra-class correlation coefficient (ICC): 0.85-0.89) in children aged 6-12 years. 21 In this study, the FPI was assessed by two examiners (podiatrists) experienced in its use (J Montes-Alguacil, A Marchena-Rodriguez), and good inter-observer reliability was found (ICC: 0.89-0.92). The assessment of a participant's foot posture included the blinding of examiners, with a folding screen placed between participant and examiner, with only the foot and 10 cm of the distal leg visible.…”

“…The FPI is summed to a total score, ranging from −12 (highly supinated) to +12 (highly pronated) . Inter‐observer reliability for the FPI has been determined to be good (intra‐class correlation coefficient (ICC): 0.85–0.89) in children aged 6–12 years . In this study, the FPI was assessed by two examiners (podiatrists) experienced in its use (J Montes‐Alguacil, A Marchena‐Rodriguez), and good inter‐observer reliability was found (ICC: 0.89–0.92).…”

Overweight, obesity and foot posture in children: A cross‐sectional study

“…Our sample of 1798 children presented an average FPI of 3.8, which coincides with the findings of Redmond and Evans et al , of 3.8 and 4, respectively, and which are within normal parameters. This foot posture is almost one point more pronated than in the adult population, for which the average FPI is 3 among the general Spanish population …”
