Abstract
Axial stress or similar properties in a stressed tendon or ligament are measured by mechanical excitation of a shear wave in the tendon or ligament measured using ultrasonic displacement techniques at least two different longitudinal positions to derive a shear wave propagation speed. This shear wave propagation speed may be equated to an axial stress on the tissue using a model. Rapidly repeated measurements allow dynamic axial stress measurements to be obtained for clinical study.
