Could a Foot Pressure Platform Replace X-ray to Diagnose Hallux Valgus Deformity?
type: CreativeWork
description: Background: Hallux Valgus (HV) is the most common deformity of the foot. Currently the ‘gold standard’ in diagnosing HV is by X-ray. It has been shown that carcinogenic effects may be associated with the frequent use of diagnostic X-rays. A wide range of foot pressure platforms exist for clinicians to perform biomechanical research of the foot during gait. However, these platforms have not been used as diagnostic tools to evaluate HV. The main aim of this study is to provide a radiation-free diagnostic and screening tool for HV, using a foot pressure platform. Methods and Materials: This study has two parts; a) a cadaveric study and b) a foot clinic study. For the cadaveric study, 20 feet from Thiel embalmed cadavers (five males and five females) were used for the cadaveric pressure study. A portable Novel EMED-M pedography platform collected pressure data from cadavers. A static cadaveric foot pressure was collected by mimicking a weight bearing standing condition for the foot. Plantar pressures, under five anatomical areas (heel, mid-foot, forefoot and toes), were investigated using the following parameters: peak pressure (PP), maximum force (MF) and contact area (CA). For the foot clinic study, 34 participants (17 patients with HV and 17 with healthy feet) were recruited. Plantar pressure during dynamic and static conditions was collected using an EMED Novel X/R high-speed pedography system. Plantar pressure, under ten anatomical areas (heel, mid-foot, 1st metatarsal head (MH), 2nd MH, 3rd MH, 4th MH, 5th MH, great toe, 2nd toe and 3rd to 5th toes), were investigated using six parameters (PP, pressure-time integral (PTI), MF, force-time integral (FTI), contact time (CT) and CA). Additionally, the accuracy of the system, in dividing the foot into multiple anatomical areas (masking), was studied by comparing an automated masking system, and masks created based on X-rays. The Hallux Valgus Angle (HVA) was measured using footprints in both groups. The correlation of …
