According to Belhan et al. (2019) heel pain in plantar fasciitis (PF) is related to the thickness of the heel fat pad thickness (THFP) and loss of elasticity. Insufficient heel fat pads reduce shock absorption and cause heel pain. In their study, it was seen that the heel pad was thinner in the painful heels of patients with PF.
Musculoskeletal ultrasound was shown to be an accurate, reliable and non-invasive imaging
technique for the measurement of THFP.
