Quantitative assessment of biceps brachii muscle stiffness by using Young's modulus-Angle curve during passive stretching in stroke patients.

ABSTRACT: Purpose: This study aims to use shear wave elastography (SWE) to dynamically describe the characteristics of biceps brachii muscle stiffness during passive stretching in healthy participants, investigate changes in the Young's modulus-angle curve under various states of muscle tone in stroke patients, and develop a new method for measuring muscle tone quantitatively. Methods: In total, 30 healthy volunteers and 54 stroke patients were evaluated for elbow flexor muscle tone on both sides using passive motion examination and were divided into groups based on their muscle tone status. The real-time SWE video of the biceps brachii and the Young's modulus data were recorded during the passive straightening of the elbow. The Young's modulus-elbow angle curves were created and fitte
