Plantar Fasciitis: Are Pain and Fascial Thickness Associated With Arch Shape and Loading? by Scott C Wearing, James E Smeathers, Patrick M Sullivan, Bede Yates, Stephen R Urry, and Philip Dubois ptjournal Volume 87(8): July 31, 2007 Physical Therapy

The thickness of the proximal insertion of the plantar fascia (d) was measured from sagittal sonograms at a standard reference point 5 mm from the anterior, inferior border of the fascial insertion into the calcaneus (C). Scott C Wearing et al. PHYS THER 2007;87: Physical Therapy
