Abstract Background: The Foot Posture Index (FPI-6) is a validated and rapid clinical method for evaluating standing foot posture through assessing six individual criteria. Although it has been widely used without radiographic examination, evidences for correlation of FPI-6 with radiographic parameters remain scanty. The objective of this study is to investigate the correlation of FPI-6 with radiographic measurements and to assess the feasibility of FPI-6 for clinical evaluation of standing foot postures. Methods: Sixty patients (M:F,33:27, mean age 62 ) of foot and ankle symptoms and 40 asymptomatic male volunteers (age, 20-28), were included in this study. FPI-6 scores were evaluated by 4 raters and inter-rater reliability of FPI-6 was assessed by intraclass correlation coefficient (ICC). Radiologic measurements including talo-first metatarsal angle (TMA), Meary’s angle (MA), talonavicular coverage angle (TNCA), talocalcaneal angle (TCA), calcaneal pitch angle (CPA), and hindfoot alignment angle (HAA) were measured. For the correlation analysis between FPI-6 and radiographic parameters, statistical analysis was performed using Pearson’s correlation test.Results: Inter-rater reliability was ‘high to excellent’ among raters. However, FPI-6 score was more repeatable in patients group and in more experienced raters. In total group, FPI-6 score was correlated with TNCA, TMA, lateral TCA, MA, and HAA. Especially, TNCA and HAA were more strongly correlated among them. When we analyzed the subdomains of FPI-6, the congruence of the medial longitudinal arch and the prominence in the region of the talonavicular joint were most strong indicators for TNCA and HAA, respectively. Conclusion: This study manifested that not only the feasibility of the FPI-6, but also its correlation to radiographic parameters, is significant for both the patients and the asymptomatic group. We assert that FPI-6 scoring system can be used as a first-line tool for foot posture assessment in clinics without radiographic evaluation if used carefully.

Background: The Foot Posture Index (FPI) is a clinical tool for diagnosis that aims to quantify the grade of a foot position as neutral, pronated, or supinated. Its purpose is to develop a simple six-factor method for rating foot posture with an easy and quantitative result. We evaluated possible differences in the FPI by sex and the influences of age, weight, height, foot size, and body mass index (BMI) on foot posture. Methods: In 150 asymptomatic children (79 boys and 71 girls) aged 8 to 13 years, we determined weight, height, BMI, and FPI in the bipedal, static, and relaxed position. The FPI was obtained as the sum of the scores (–2, –1, 0, 1, 2) given to each of the six criteria. Results: The mean ± SD FPI value for the total sample was 5.1 ± 2.1 (boys: 5.1 ± 2.2; girls: 5.2 ± 2.0), so there were no significant differences between the sexes (P = .636). Of the 150 feet examined, none had FPI values of very supinated or highly pronated, two were supinated (1.3%), 76 neutral (50.7%), and 72 pronated (48.0%). Of the total FPI values, 7.7% can be explained by anthropometric variables: height, weight, and foot size (r2 = 0.077; P < .010). Conclusions: The most frequent foot postures in the sample were neutral and pronated. Neither age nor BMI explained variations in the FPI.

<p><strong>Objective</strong><strong>: </strong>This study investigated the relationship between foot type and ankle sprain incidence.</p><p><strong>Method</strong><strong>: </strong>In a prospective cohort study using the FPI, 68 adult male and female indoor football (Futsal) players were measured and their feet were classified according to foot posture index (FPI) as neutral, supinated and pronated. They were followed over 6 month as a one competition season and at the end, any injuries at the ankle during this period were detected.</p><p><strong>Result</strong><strong>: </strong>There was no significant association between FPI score (considering the total FPI score and its six components) and occurrence of ankle sprain. Also, no association was existed between gender, age, height, weight, BMI, duration of professional exercise, dominant foot and occurrence of ankle sprain. In this study, the history of previous ankle sprain was the only significant predictor of the occurrence of ankle sprain in the follow-up period. Participants with the positive history of previous ankle sprain were at higher risk of developing new ankle sprain (OR=6.02, 95% CI: (1.93, 18.84), p=0.002).</p><p><strong>Conclusion</strong><strong>: </strong>There was no significant association between FPI score and occurrence of ankle sprain.<strong></strong></p><p><strong>Limitation: </strong>there was scarce of supinated foot in the study so evaluation of relationship between supinated feet and ankle sprain was not applicable.</p>

The Foot Posture Index is a new multidimensional and multiplanar tool aimed at quantifying the degree of pronation to supination of the foot, comprising eight criteria that sum to produce a final “score” of foot posture. In an initial study involving 31 subjects, angulations measured from dorsoplantar and lateral radiographs were compared with the corresponding Foot Posture Index criteria using Spearman’s rho and the generalized linear model of analysis of variance. Eleven of the participants from Study 1 completed a second study in which wedges were used to alter foot position to determine whether changes to foot position were sensitively reflected in Foot Posture Index criterion scores and associated radiographic images. Study 1 demonstrated a significant correlation for only one criterion (talar head palpation), while Study 2 demonstrated intrasubject sensitivity to overall changes from supinated to pronated and supinated to resting positions but insensitivity to changes from resting to pronated positions. The results suggest that although the Foot Posture Index could be a useful tool to broadly classify foot postures, it is not sensitive to all small movements when assessed by this method.

Background: The path of the center of pressure during walking varies among individuals by deviating to a greater or lesser extent toward the medial or lateral border of the foot. It is unclear whether this variance is systematic and is affected by foot posture. The aim of this study was to explore the relationship between foot morphology and center-of-pressure excursion during barefoot walking. Methods: Pressure data were collected from 83 participants whose foot type had been classified as supinated, normal, or pronated according to the Foot Posture Index. Three center-of-pressure variables were analyzed: medial excursion area, lateral excursion area, and total excursion area. Results: Across the spectrum of foot types, we found that the more supinated a participant’s foot posture, the larger the area of lateral center-of-pressure excursion, and, conversely, the more pronated the foot posture, the smaller the area of lateral center-of-pressure excursion. Furthermore, the supinated foot type had a relatively larger center-of-pressure total excursion area, and the pronated foot type had a relatively smaller center-of-pressure total excursion area. Conclusions: These results indicate the importance of assessing foot posture when measuring center of pressure and may help explain regional differences in pain and injury location among foot types.

Objectives : To compare foot posture in people with and without medial compartment knee osteoarthritis (OA), and to assess association between its abnormalities and medial compartment knee OA. Methods : We compared the foot posture of patients with clinically and radiographically-confirmed medial compartment knee OA and asymptomatic healthy controls using the foot posture index (FPI), navicular height, and the medial arch. Results : We included 100 patients and 80 asymptomatic controls. The mean age of patients was 59 ± 7 (44-76) years and 48 ± 9 (28-60) years in the control (p=0.06). Patients group have more pronated foot for FPI (1.50 ± 2.68 vs 0.72 ± 2.63; p=0.05), more flat foot (42% vs 22%; p=0.03), and less pes cavus than the control group (58% vs 77%; p=0.004). However, there was no significant difference between the groups in the navicular height (3.90 ± 0.85 cm vs 4.00 ± 0.76 cm; p=0.41). In multivariate statistical analysis, after adjusting for age and body mass index, pronated foot in FPI (OR=1.22, 95%IC= [1.06-1.40], p=0.005), and pes cavus (OR=0.32, 95%IC= [0.11-0.93], p=0.03) had a significant correlation with the knee osteoarthritis. Conclusion : Pronated foot posture and flat foot are significantly associated with medial compartment knee osteoarthritis.
