Normative Values for Microvascular Flow and Elastography Measurements in the Asymptomatic Posterior Leg and Gastroc-Soleus-Achilles Complex - AIUM 2024

Persinger J, Hager N, Grogan S, Mincey C

The Geneva Foundation (Tacoma, WA) in conjunction with Uniformed Services University of the Health Sciences (USUHS), and the Podiatry Clinic at Madigan Army Medical Center (MAMC) is conducting a research study to establish normative values for thickness and cross-sectional area (CSA), microvascular flow states, power Doppler flow states, and Young’s modulii in the posterior lower leg muscles (gastroc/soleus) and Achilles tendon. This study supports a concurrent study attempting to validate shear-wave elastography (SWE) and microvascular flow (MVF) as a novel, sensitive, and non-invasive means of determining the health and recovery state of the above structures.

Achilles tendinopathy, plantar fasciitis, and chronic exertional compartment syndrome (CECS) are commonly seen in the active-duty service member and military recruit population. These conditions are common contributors to significant warfighter disability, impacting operational readiness. Non-invasive technology such as microvascular flow and shear wave elastography may prove to be timely and cost effective.
