Multi-segment foot kinematics and ground reaction forces during gait of individuals with plantar fasciitis

Abstract Background Clinically, plantar fasciitis (PF) is believed to be a result and/or prolonged by overpronation and excessive loading, but there is little biomechanical data to support this assertion. The purpose of this study was to determine the differences between healthy individuals and thos...

Description
Summary:Abstract Background Clinically, plantar fasciitis (PF) is believed to be a result and/or prolonged by overpronation and excessive loading, but there is little biomechanical data to support this assertion. The purpose of this study was to determine the differences between healthy individuals and those with PF in (1) rearfoot motion, (2) medial forefoot motion, (3) first metatarsal phalangeal joint (FMPJ) motion, and (4) ground reaction forces (GRF). Methods We recruited healthy ( n =22) and chronic PF individuals ( n =22, symptomatic over three months) of similar age, height, weight, and foot shape ( p >0.05). Retro-reflective skin markers were fixed according to a multi-segment foot and shank model. Ground reaction forces and three dimensional kinematics of the shank, rearfoot, medial forefoot, and hallux segment were captured as individuals walked at 1.35 ms−1. Results Despite similarities in foot anthropometrics, when compared to healthy individuals, individuals with PF exhibited significantly ( p
