Convergent validity and test-retest reliability of multimodal ultrasound and related clinical measures in people with chronic stroke
Unilateral alterations in muscle structure1, composition2,3, viscoelastic characteristics3 and microvasculature4 are evident during chronic stages of stroke recovery. Changes to paretic muscle tissue after stroke are mechanistically complex and often inconsistent with alterations typically resulting from disuse, over-stimulation or aging alone5,6. Ultrasound provides a clear diagnostic advantage for objectively measuring muscle changes in real-time7. While commonly used assessments and scales (e.g., Modified Ashworth and Tardieu) provide a clinical gradation of neuromuscular dysfunction (i.e., degree of spasticity, resista...

Measurement of Altered Muscle Properties in Stroke-impaired Muscle Using Shear Wave Ultrasound Elastography
To investigate changes in muscle properties in stroke-impaired muscle, specifically 1) material properties by using a novel technology, shear wave (SW) ultrasound elastography, to measure SW velocity which is related to stiffness and 2) muscle composition by using B-mode ultrasound imaging to measure echogenicity. The second aim was to determine if these changes are related to functional impairment.
