神经传导测定技术对腕管综合征病情评估的价值

目的:近年来腕管综合征发病率逐年升高,然而其慢性、隐匿性不易引起人们的重视,发现时往往已造成较大的危害。本文探讨腕管综合征的神经传导测定对病情评估的临床价值,旨在为患者腕管综合征早期发现和后续治疗提供进一步的临床参考依据。方法:选取我院124例确诊的腕管综合征患者。其中无大鱼际肌萎缩者有64例,并选取平均年龄相近的64例正常人作为对照(组A);有大鱼际肌畏缩者60例,并选取平均年龄相近的60例正常人作为对照(组B)。A、B组均经行神经电图检查,握力测定和两点辨别觉测定,分析神经传导速度改变与感觉、运动功能减退程度的关系。结果:A、B两组患者均有不同程度的神经传导改变:在A组患者神经传导改变中,运动和感觉传导速度(MCV和SCV)轻度下降,运动和感觉电位波幅(CMAP和SNAP)轻度下降,潜伏期(ML)轻度延长;在B组患者神经传导中,运动和感觉传导速度(MCV和SCV)明显下降,运动和感觉电位波幅(CMAP和SNAP)明显下降,潜伏期明显延长。结论:腕管综合征患者不同的临床表现有不同程度的神经电图表现,因此神经电图对神经传导的测定结果对腕管综合征患者的病情有良好的评估价值,值得临床推广。

Value of Nerve Conduction Measurement for the Assessment of Carpal Tunnel Syndrome

Objective:The incidence of carpal tunnel syndrome is increasing in recent years, but it is chronic and secretive, so the carpal tunnel syndrome is hard to cause the attention of people. carpal tunnel syndrome also tends to have larger damage when found. This article is to discuss the clinical value of nerve conduction measurement technology for the carpal tunnel syndrome, and to provide further clinical data for the early detection of carpal tunnel syndrome and the follow-up treatment.Methods:124 patients with carpal tunnel syndrome who were diagnosed in our hospital were selected and divided into two groups (group A and group B) .Group A: 64 cases of the patients with no big thenar muscle atrophy, select 64 cases of normal people who have the same average age as control; Group B:60 cases of the patients have big thenar muscle atrophy, select 60 cases of normal people who have the same average age as control. All the patients were detected by the nervous electrical diagram, grip strength and the sense of two-point discrimination to analyze the relationships of the nerve conduction velocity, the sensory and the motor functions.Results:The two groups have varying degrees of nerve conduction. For the nerve conduction of group A: The motor conduction velocity and sensory conduction velocity have mild decline, the compound muscle action potential amplitude and sensory nerve action potential amplitude have mild decline, and the incubation period extended slightly; For the nerve conduction of group B: The motor conduction velocity and sensory conduction velocity have dramatic decline, the compound muscle action potential amplitude and sensory nerve action potential amplitude have dramatic decline, and the incubation period extended dramatically.Conclusion:Patients who have different clinical manifestations also have different degrees of neural electrical performance. Nervous electrical diagram for the nerve conduction measurement have a great assessment value for the patients with carpal tunnel syndrome, it is worthy of clinical promotion.
