QUANTIFY: Quantitative Understanding of Advanced Novel Techniques for Imaging Fasciitis and Yielding Biomarkers

An experienced physical therapist with expertise in dry needling will confirm study eligibility and complete a standard clinical exam for myofascial pain. Gold standard for diagnosing myofascial pain as defined by Travell and Simons will be used. The criteria for muscle trigger point (TrP) include: 1) a taut band of skeletal muscle that is tender to palpation, 2) sustained compression of the taut band reproduces or exacerbates the participant's symptoms. Healthy tissue is defined as no palpable taut band.

Shear wave elastography and b-mode ultrasound imaging techniques will capture the biomechanical and structural profile of foot and ankle muscle on the involved side.

T1rho and IDEAL sequences will be used to capture the biochemical and structural profile of foot and ankle muscles on the involved side
