Abstract: Objective To assess the stiffness and thickness of the plantar fascia using shear wave elastography (SWE) in healthyvolunteers of different ages and in patients with plantar fasciitis. Methods The bilateral feet of 30 healthy volunteers and 23patients with plantar fasciitis were examined with SWE. The plantar fascia thickness and elasticity modulus value weremeasured at the insertion of the calcaneus and at 1 cm from the insertion. Results The elderly volunteers had a significantlygreater plantar fascia thickness measured using conventional ultrasound (P=0.005) and a significantly lower elasticity modulusvalue than the young volunteers (P=0.000). The patients with fasciitis had a significantly greater plantar fascia thickness (P=0.001) and a lower elasticity modulus value than the elderly volunteers (P=0.000). The elasticity modulus value wassignificantly lower at the calcaneus insertion than at 1 cm from the insertion in patients with fasciitis (P=0.000) but showed nosignificantly difference between the two points in the elderly or young volunteers (P=0.172, P=0.126). Conclusion SWE allowsquantitative assessment of the stiffness of the plantar fascia, which decreases with aging and in patients with plantar fasciitis.
