“…This is inconsistent with our results, and it may be due to our longer training session (3 hrs) and use of Redmond’s clinical note7 ) for scoring the individual items. Our reported reliability is also inconsistent with that of Aquino et al10 ) , who demonstrated a moderate to good inter- and intra-rater reliability of the total raw FPI-6 score (ICCs 0.45–0.88) in healthy adults. For foot posture classification, this study reports a moderate to substantial intra- and inter-rater agreement for the total FPI-6 score and a fair to almost perfect inter- and intra-rater agreement for the individual items of the FPI-6.…”

[Purpose] To investigate the reliability of novice and experienced physiotherapists using the normalized navicular height truncated and the foot posture index-6 for classifying foot posture in healthy adults. [Participants and Methods] Thirty asymptomatic adults participated in this study. After brief training, inter-rater reliability was performed by an expert and inexperienced rater (the novice physiotherapist). On the same day, both raters independently performed the normalized navicular height truncated and the foot posture index-6. For intra-rater reliability, the inexperienced rater repeated data collection on the 8th day after the first assessment. Intraclass correlation coefficients (ICCs) and Cohen’s Weighted Kappa ( K w ) were used for continuous and categorical data, respectively. [Results] The normalized navicular height truncated and the Rasch-converted foot posture index-6 scores demonstrated an excellent inter- and intra-rater reliability (ICCs=0.98–0.99). For classifying foot posture, the normalized navicular height truncated and the total foot posture index-6 scores represented more than 90% inter- and intra-rater agreement with K w values ranging from 0.92–0.94, while each item of foot posture index-6 demonstrated inter- and intra-rater agreement ranging from substantial to almost perfect ( K w =0.71–0.94). [Conclusion] The normalized navicular height truncated and the foot posture index-6 are simple and reliable methods that can be used by the inexperienced rater.

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.

“…Values between 0 and +5 are considered a normal foot, < 0 supinated and > 5 pronated [20]. Intrarater reliability of the total test score was previously determined as moderate to high (ICC of 0.66 with CI between 0.45 and 0.82), and interrater reliability was also moderate to high (ICC of 0.79 with CI between 0.64 and 0.88) [21].…”

Hyperelastic tape modifies the kinematics of the pronated foot in young women: self-controlled clinical trial

et al. 2020

Introduction: Excessive pronation has been linked to increased risk of developing lower limb injuries. In this respect, assessing the effectiveness of therapeutic resources, such as hyperelastic taping, becomes relevant. Objective: evaluate the influence of adhesive hyperelastic taping on excessive pronation of the ankle-foot complex in young women. Method: Self-controlled clinical trial of ten women with excessive pronation (Foot Posture Index ≥ 6). Three-dimensional gait was assessed according to the Vicon Oxford Foot Model before and after taping. Hyperelastic tape was applied on the side with greater pronation (experimental side) and the opposite side was used as control (control side). The segments evaluated were the hindfoot, midfoot and forefoot. The Shapiro-Wilk normality, paired t and Wilcoxon tests were applied and Significance was set at p <0.05. Results: No change (p> 0.05) was observed in the hindfoot on the experimental or control side; the midfoot showed a decrease in arch height (p <0.05) only on the experimental side; forefoot eversion (p <0.05) declined only on the experimental side. Conclusion: The use of hyperelastic tape reduced forefoot eversion; however, this decrease is not clinically desirable, since excessive pronation in a closed chain increased in the sample of young women studied.
