Trial Parameters
Brief Summary
The purpose of this study is to utilize Shear Wave Elastography (SWE) to study the viscoelastic properties of tendons to understand the functional differences between normal/asymptomatic and symptomatic tendon states. The study will also assess the degree of tendon healing following standard of care treatment.
