Ultrasound elastography in assessment of post-stroke spasticity of the biceps brachii muscle

摘要

Approximately 15 million people experience a stroke each year worldwide and two-thirds of these individuals require rehabilitation. Post-stroke spasticity is one of the common consequences characterized by excessive muscle tone resulting in an increase of muscle stiffness. To date, the assessment of spasticity is still a lack of gold standards. We prospectively evaluated the feasibility of ultrasound strain imaging (USI) to assess biceps brachii muscle (BBM) stiffness and dynamic motion in subjects with post-stroke spasticity.
