Aplio's Smart Maps allow you to visualize and quantify shear wave propagation in a user-defined region of interest in realtime. The user can select both dynamic propagation speed and elasticity displays for visual assessment and quantification.
Ultrasound elastography is a means of assessing the mechanical properties of tissue, by
applying stress and detecting tissue displacement using ultrasound. It provides information
on tissue stiffness.
Ultrasound shear wave elastography has been used to assess muscle stiffness in people with
Parkinson's Disease. The assessments were made by assessing the biceps of people with
Parkinson's Disease.
Ultrasound shear wave elastography of the
longitudinal biceps brachii was performed on 46
people with Parkinson's Disease and 31 healthy
controls The mean Young's modulus was 59 kPa in
remarkably symptomatic arms, 47 kPa in mildly
symptomatic arms, and 24 kPa in healthy controls.
A significant difference was found between healthy
controls and all people with Parkinson's Disease.
The distinctiveness of the results enable Ultrasound shear wave elastography to be used as a
quantitative assessment of muscle stiffness in people with Parkinson's Disease.

The principle behind shear wave elastography
Shear waves are generated inside the human body by means of an ultrasonic burst (left). Depending on tissue stiffness, shear waves travel at varying speed, but generally very slowly through the human body. Their propagation can be followed and visualized using conventional ultrasound imaging techniques (right). The propagation speed of the shear waves directly correlates with tissue stiffness
