Correlation of Foot Posture Index With Plantar Pressure and Radiographic Measurements in Pediatric Flatfoot

Abstract

ObjectiveTo investigate the correlation between the Foot Posture Index (FPI) (including talar head palpation, curvature at the lateral malleoli, inversion/eversion of the calcaneus, talonavicular bulging, congruence of the medical longitudinal arch, and abduction/adduction of the forefoot on the rare foot), plantar pressure distribution, and pediatric flatfoot radiographic findings.MethodsNineteen children with flatfoot (age, 9.32±2.67 years) were included as the study group. Eight segments of plantar pressure were measured with the GaitView platform pressure pad and the FPI was measured in children. The four angles were measured on foot radiographs. We analyzed the correlation between the FPI, plantar pressure characteristics, and the radiographic angles in children with flatfoot.ResultsThe ratio of hallux segment pressure and the second through fifth toe segment pressure was correlated with the FPI (r=0.385, p=0.017). The FPI was correlated with the lateral talo-first metatarsal angle (r=0.422, p=0.008) and calcaneal pitch (r=-0.411, p=0.01).ConclusionOur results show a correlation between the FPI and plantar pressure. The FPI and pediatric flatfoot radiography are useful tools to evaluate pediatric flatfoot.

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

“…A study of 187 children found both the FPI and radiographic measures to be useful for evaluating flat feet; however, our results found that footprint measures are only valid for the paediatric flat foot (planus), with no clear association for either high‐arch (cavus) or normal‐arch (rectus) feet. Hence, footprint and foot posture measures potentially measure different aspects of the foot structure.…”

“…showed a correlation between the FPI and plantar pressure, concluding that the FPI and radiography are both useful tools to evaluate paediatric flat foot. This sample included 19 children with flat foot (9.32 ± 2.67 years) as the study group . Plantar pressures using footprints and pressure platforms have also been investigated.…”

“…This sample included 19 children with flat foot (9.32 AE 2.67 years) as the study group. 33 Plantar pressures using footprints and pressure platforms have also been investigated. Kadhim et al showed that medial midfoot pressure correlated with talonavicular joint uncoverage index, talonavicular angle, medial arch angle, Meary angle and lateral talocalcaneal angle.…”

The Effect of Arch Height and Material Hardness of Personalized Insole on Correction and Tissues of Flatfoot

“…Orthopedic insoles have been revealed to be an effective treatment for flatfoot by elevating the arch height and recovering the body weight supporting and force transmission [5]. Due to the difference between individuals (soft tissue material properties, flatness, etc.…”

Does diabetes affect stability in people with unilateral transtibial amputation?

“…Static and dynamic plantar pressure were measured during standing and walking in shoes using the Gaitview AFA-50 system (alFOOTs, Seoul, Republic of Korea), which includes a 700 × 500 × 45 mm active area, consisting of a 3 mm thick floor mat, comprising 2,304 (48 × 48) force-sensitive sensors; test time: changeable; maximum pressure: 100 N/cm 2 ; acquisition frequency: ≤ 86 images per second. In previous studies, this system demonstrated good to moderate reliability [19,20]. We used the twostep method.…”
