摘　　要：目的观察电流感觉阈值测试诊断神经根型颈椎病的特点并分析其诊断价值。方法收集2020年至2022年武汉华润武钢总医院收治的67例单侧发病神经根型颈椎病患者,对损伤的颈神经根节段进行双上肢相应皮区的CPT测试,患侧为实验组,健侧为对照组,行CPT评分比较;以患侧上肢是否存在疼痛症状,将实验组分为疼痛组和非疼痛组,统计疼痛组和非疼痛组2000Hz、250Hz、5Hz三种频率的CPT测试结果的异常率,分别行组内和组间比较。结果实验组92.54%患者CPT测试结果异常,实验组CPT评分高于对照组(t=15.653,P<0.001),疼痛组和非疼痛组CPT评分差异不具有统计学意义(t=0.070,P=0.944>0.05);疼痛组5HzCPT测试结果异常率高于2000Hz和250Hz异常率(2000Hz和5Hz比,P<0.001;250Hz和5Hz比,P<0.001)。疼痛组250Hz和5HzCPT测试结果异常率分别高于非疼痛组(两组250Hz比较P=0.029<0.05;两组5Hz比较P<0.001)。结论CPT测试是一种有效诊断神经根型颈椎病的方法,且对疼痛和非疼痛患者的评价效果一致。疼痛患者主要表现为5HzCPT测试值异常。Objective To observe the characteristics and analyze the diagnostic value of current perception threshold test in the diagnosis of cervical Spondylotic radiculopathy.Methods67 patients with unilateral cervical Spondylotic radiculopathy treated in China Resources and WISCO General Hospital from 2020 to 2022 were collected and their injured cervical nerve root segments were tested by CPT test in the corresponding skin area of both upper limbs,with the affected side as the experimental group and the healthy side as the control group,and the CPT scores was compared.According to whether there were pain symptoms in the affected upper limb,the experimental group was divided into pain group and non-pain group,and the abnormal rates of CPT test results of 2000Hz,250Hz and 5Hz in pain group and non-pain group were counted and compared within and between groups.Results The CPT test result of 92.54%patients in the experimental group was abnormal,and the CPT test result of the experimental group was higher than that of the control group(t=15.653,P<0.001),and there was no significant difference in the CPT score between pain group and non-pain group(t=0.070,P=0.944>0.05).The abnormal rate of 5HzCPT test result in the pain group was higher than that of 2000Hz and 250HzCPT test values(2000Hz/5Hz ratio in experimental group,P<0.001;250Hz/5Hz ratio in experimental group,P<0.001;2000Hz/5Hz ratio in pain group,P<0.001;250Hz/5Hz ratio in pain group,P<0.001).The abnormal rate of 5Hz and 250HzCPT in the pain group was higher than that in the nonpain group(250Hz abnormal rate in the two groups P=0.029<0.05;5Hz abnormal rate in the two groups P<O.oo1).Conclusion CPT test is an effective method for the diagnosis of radiculotic cervical spondylosis,and the evaluation effect is the same in pain and non-pain patients.Patients with pain mainly present with abnormal 5HzCPT test values.
