  • Title: Quantitative Ultrasound Assessment of the Achilles Tendon Under Varied Loads.
    Author: Sahr M, Sturnick DR, Nwawka OK.
    Journal: J Ultrasound Med; 2018 Oct; 37(10):2413-2418. PubMed ID: 29516536.
    Abstract:
    This Institutional Review Board-approved pilot study attempted to detect the correlation between ultrasound shear wave elastographic measures and tendon loads. Five male fresh-frozen cadaveric Achilles tendons were loaded in 10-N increments from 0 to 60 N. Shear wave velocity measurements within each Achilles tendon were obtained at each load in longitudinal and transverse orientations. Shear wave velocity measurements were correlated with tendon tension on both longitudinal and transverse plane imaging and showed moderate and strong positive correlation coefficients, respectively. Of note, limitations of the clinically available shear wave elastographic technology for measuring high velocities exist.
