| 【】目的：比较观察肌电图(electromyography ,EMG)与颈椎核磁共振(nuclear magnetic resonance ,MRI)用于诊断神经根型颈椎病的临床应用价值。方法：以2015年6月~2016年6月我院门诊及收治的92例神经根型颈椎病患者为研究对象,入选研究对象均进行肌电图和颈椎MRI检查。比较两种检查方法对神经根型颈椎病的诊断率,比较两种检查方法测得患者神经累及节段数量以及对两组检查方法的受累及节段定位准确度进行比较。结果：(1) EMG诊断神经根型颈椎病的阳性率为98.91%(91/92),颈椎MRI诊断神经根型颈椎病的阳性率为95.65%(90/92),诊断率比较差异不具统计学意义(P<0.05)；(2) 颈椎MRI检查累及3个及以上神经节段数高于EMG检查法,差异具有统计学意义(P<0.05)；(3) 颈椎MRI累及的颈4-5间盘者、累积的颈7-胸1间盘患者比例明显高于EMG检查相应的C5、C7神经根,差异具有统计学意义(P<0.05),提示EMG检查法有更高的定位准确度。结论：肌电图与颈椎MRI对神经根型颈椎病的诊断均有较高的诊断率,但肌电图检查法的定位神经根位置范围更小,精确度更高。总之,肌电图诊断神经根型颈椎病有着较高的临床应用价值,可为神经根型颈椎病的手术治疗提供参考。 |

| Objective: To compare the clinical value of EMG (electromyography) and MRI (nuclear magnetic resonance) in the diagnosis of cervical spondylotic myelopathy. Methods: 92 patients with nerve root type cervical spondylosis in our hospital from June 2015 to ~2016 in June were selected as subjects. The subjects were examined by electromyography and MRI. To compare the diagnostic rate of two kinds of inspection methods for cervical spondylosis of nerve root type, to compare the number of patients with the cumulative number of nerve segments, and to compare the accuracy of the two methods of the cumulative positioning of the two groups. Results: (1) the positive rate of EMG in the diagnosis of cervical spondylosis of nerve root type 97.83% (90/92), the positive rate of MRI in the diagnosis of cervical spondylosis of 98.91% audit relationship (91/92), the diagnostic rate of the difference was not statistically significant (P<0.05); (2) cervical MRI examination accumulated more than 3 and higher than that of EMG examination of God the number of segments, the difference was statistically significant (P<0.05); (3) cervical MRI cumulative carotid 4-5 intervertebral disc, cervical 7- cumulative 1 thoracic intervertebral disc patients was significantly higher than the proportion of EMG check the corresponding C5, C7 nerve root, the difference was statistically significant (P<0.05), suggesting that EMG has more test location high accuracy. Conclusion: the diagnosis of cervical spondylosis of nerve root type is higher than that of EMG and cervical MRI, but the location of nerve root is smaller and the precision is higher. In conclusion, EMG diagnosis of nerve root type of cervical spondylosis has a high clinical value, can provide reference for the surgical treatment of cervical spondylotic myelopathy. |
