2. 肌张力增高 :多由上运动神经元损伤、锥体外系损害引发,被动活动肢体阻力增大。阻力包含两部分:动态(拉伸时神经反射 + 肌肉生物力学因素)、静态(肌肉弹性势能,非神经来源)。肌张力增高同时混合神经性、非神经性(肌肉、结缔组织黏弹性改变)双重因素。

3. 巴宾斯基反射阳性 :大脚趾背伸,其余脚趾扇形张开,属于痉挛的特征病理征。

非神经源性肌张力增高 :后期肌肉、结缔组织黏弹性改变,关节挛缩,和反射亢进无关。

总结:痉挛≠肌张力增高。痉挛是 速度依赖的神经源性肌张力增高 ;而肌张力增高还包含后期肌肉挛缩、结缔组织改变带来的非神经阻力。中枢神经损伤患者,僵硬往往是两者叠加,康复评估时需要加以区分,不能把所有肢体僵硬都简单判定为痉挛。
