The quarter-ellipsoid foot: A clinically applicable 3-dimensional composite measure of foot deformation during weight bearing.

摘要: Abstract Study Design Descriptive Laboratory Objectives To assess change in foot morphology across loading using innovative, clinically accessible 3-dimesional composite measurements of surface area (SA), volume (V), and SA:V ratio recreationally-active young adults. Methods The feet 53 female [mean age:20.7 ± 3.8 years, BMI:23.9 4.2 kg m−2, posture index (FPI):3.8 3.7] 31 male participants (mean age:20.8 2.4 BMI:23.7 2.5 FPI:3.8 4.1) were evaluated. FPI was assessed length, width, dorsal arch height measured sitting bipedal standing used to calculate the SA V a quarter-ellipsoid. ΔSA characterized widening lengthening ΔV deformation during loading. represented changes both size shape. Linear regression performed effects component measures on measurements. compared established ΔArch Height Index (ΔAHI), Arch Flexibility, Foot Mobility Magnitude (FMM), FPI.
