About

Achilles tendon plays a significant role in walking and sporting activities, particularly through ankle joint and lower limbs stability. Ultrasound imaging can be the first-line examination of choice for patients suspected of having Achilles tendon injury, which is more and more frequent. Nowadays, ultrasound elastography can be used to evaluate the viscoelasticity properties of Achilles tendon, however little is known about the reproducibility of the technique. This study aims to evaluate the reproducibility of supersonic shear imaging SWE™ Young's modulus measurements of shear wave velocity (m/s) in Achilles tendon and plantar fascia.

Enrollment: 1,165 patients
