Fit to Burst: Toward Noninvasive Estimation of Achilles Tendon Load Using Burst Vibrationshttps://www.embs.org/tbme/wp-content/uploads/sites/19/2021/01/TBME-00318-2020-Highlight-Image.jpg170177IEEE Transactions on Biomedical Engineering (TBME)IEEE Transactions on Biomedical Engineering (TBME)//www.embs.org/tbme/wp-content/uploads/sites/19/2022/06/ieee-tbme-logo2x.png
In this study, we present a novel method of noninvasively estimating mechanical load in the Achilles tendon using burst vibrations. These vibrations, produced by a small vibration motor on the skin superficial to the tendon, are sensed by a skin-mounted accelerometer, which measures the tendon’s response to burst excitation under varying tensile load. Characteristic changes in the burst response profile as a function of tendon tension are observed and used as inputs to an ML model, which yields accurate (R2 = 0.85) estimates of ankle loading during gait. Preliminary results of a fully wearable ankle load monitor are also presented.
