剪切波超声弹性成像在脑卒中后痉挛肢体中的应用及研究进展

Application and research progress of shear wave ultrasonic elastography in spastic limbs after stroke

痉挛是由于上运动神经元受损后速度依赖性肌肉张力增加及对牵张反射异常兴奋的运动障碍,其治疗依赖于对痉挛的精准评估。剪切波超声弹性成像作为一种新兴的痉挛评估方法,具有实时、使用范围广泛、操作简单、经济等优点,能克服其他肌肉痉挛评估技术在临床应用中的不足。该文就剪切波超声弹性成像在脑卒中后痉挛评估和痉挛康复疗效中的应用进行了综述,并对其在脑卒中后痉挛康复中的应用进行了展望。

Spasticity is a movement disease caused by increased velocity dependent muscle tone and abnormal excitation of stretch reflex after damage to upper motor neurons,and its treatment depends on accurate evaluation of spasticity.One newly developed technique for assessing spasticity is shear wave ultrasonic elastography.It may overcome the drawbacks of other clinical muscle spasm evaluation approaches and offers the benefits of real-time,wide range of application,simplicity of operation,and economy.Therefore,this article reviewed the application of shear-wave ultrasonic elastography in the evaluation and rehabilitation of spasticity after stroke,and prospects its application in rehabilitation of spasticity after stroke.
