Shear Wave Tensiometry in the Evaluation of Achilles Tendon Loading: A Cross‐Sectional Study on Conservatively Treated Tendons After Rupture [PDF]
Journal of Foot and Ankle ResearchPurpose The aim of this study was to quantify differences in the shear wave speed (SWS) between a conservatively treated Achilles tendon (AT) after rupture and the unaffected contralateral tendon.

A Single-Sensor Approach for Noninvasively Tracking Phase Velocity in Tendons during Dynamic Movement [PDF]
Micromachines, 2023 Shear wave tensiometry is a noninvasive method for directly measuring wave speed as a proxy for force in tendons during dynamic activities. Traditionally, tensiometry has used broadband excitation pulses and measured the wave travel time between two ...

A Kalman Filter Approach for Estimating Tendon Wave Speed from Skin-Mounted Accelerometers [PDF]
Sensors, 2022 Shear wave tensiometry is a noninvasive approach for assessing in vivo tendon forces based on the speed of a propagating shear wave. Wave speed is measured by impulsively exciting a shear wave in a tendon and then assessing the wave travel time between ...

Residual force enhancement is affected more by quadriceps muscle length than stretch amplitude [PDF]
eLife, 2022 Little is known about how muscle length affects residual force enhancement (rFE) in humans. We therefore investigated rFE at short, long, and very long muscle lengths within the human quadriceps and patellar tendon (PT) using conventional dynamometry ...

Shear Wave Tensiometry Reveals an Age-Related Deficit in Triceps Surae Work at Slow and Fast Walking Speeds [PDF]
Frontiers in Sports and Active Living, 2020 Prior studies have observed an age-related decline in net ankle power and work at faster walking speeds. However, the underlying changes in muscle-tendon behavior are not well-understood, and are challenging to infer from joint level analyses. This study

Shear wave propagation in the Achilles subtendons is modulated by helical twist and non-uniform loading [PDF]
Royal Society Open ScienceThe triceps surae is composed of the medial gastrocnemius, lateral gastrocnemius and soleus muscles. Each muscle inserts onto a subtendon that undergoes helical twist prior to insertion onto the calcaneus.

Biomechanical Properties of Strictures in Crohn's Disease: Can Dynamic Contrast-Enhanced Ultrasonography and Magnetic Resonance Enterography Predict Stiffness? [PDF]
Diagnostics (Basel), 2022 Strictures and abdominal pain often complicate Crohn’s disease (CD). The primary aim was to explore whether parameters obtained by preoperative contrast-enhanced (CE) ultrasonography (US) and dynamic CE MR Enterography (DCE-MRE) of strictures associates ...

Achilles tendon shear wave speed tracks the dynamic modulation of standing balance [PDF]
Physiological Reports, 2019 Standing balance performance is often characterized by sway, as measured via fluctuations of the center of pressure (COP) under the feet. For example, COP metrics can effectively delineate changes in balance under altered sensory conditions. However, COP
