Abstract

To better understand the effects of spasticity on peripheral nerves, we evaluated the electrodiagnostic and nerve ultrasonographic features of the median and ulnar nerves in adults with upper limb spasticity. Twenty chronic stroke patients with spastic hemiparesis underwent nerve conduction study and nerve ultrasonography of the median and ulnar nerves at both upper limbs. Affected versus unaffected upper limb comparisons showed significant differences in the median and ulnar nerve distal motor latencies, compound muscle action potentials and F-wave minimal latencies. Furthermore, we observed a significantly greater median nerve crosssectional area at the elbow of the affected upper limb compared with the unaffected one. Our findings confirmed electrodiagnostic asymmetries and nerve ultrasonographic abnormalities in the affected versus the unaffected upper limb after stroke. Slight changes in lower motor neuron activity and spasticity might contribute to these alterations.

上肢痉挛的电诊断和神经超声特征:一项观察性研究。
为了更好地了解痉挛对周围神经的影响,我们评估了成人上肢痉挛患者正中神经和尺神经的电诊断和神经超声特征。20 名患有痉挛性偏瘫的慢性中风患者接受了双上肢正中神经和尺神经的神经传导检查和神经超声检查。受影响上肢与未受影响上肢的比较显示,正中神经和尺神经远端运动潜伏期、复合肌肉动作电位和F波最小潜伏期存在显著差异。此外,我们还观察到,与未受影响的上肢相比,受影响上肢肘部的正中神经横截面积明显更大。我们的研究结果证实了中风后患侧上肢与非患侧上肢的电诊断不对称和神经超声异常。下运动神经元活动和痉挛的轻微变化可能是导致这些改变的原因。
