Relationship of Body Mass Index, Ankle Dorsiflexion, and Foot Pronation on Plantar Fascia Thickness in Healthy, Asymptomatic Subjects

Abstract

Body mass index and foot supination at the subtalar joint are related to increased thickness at the plantar fascia in healthy, asymptomatic subjects. Although the changes in thickness were small compared with those in patients with symptomatic plantar fasciitis, they could play a role in the mechanical properties of plantar fascia and in the development of plantar fasciitis.
