摘要
目的评测运动神经传导速度(MNCV)检查对于确证尺神经损伤的价值,初步研究各项MNCV相关指标与肌力(MP)的相关性。方法以25例尺神经损伤的男性患者作为患病组,同时选择25例健康男性作为对照组。MNCV测定指标包括:潜伏期,波幅,MNCV值。测定前,由同一操作医师测定患者相应的MP(小指展肌、第一骨间肌和尺侧腕屈肌)。结果两组间对比,各项指标均存在显著性差异;患病组MP与MNCV和波幅存在显著相关性。结论MNCV检验可用于确证尺神经损伤,并可初步推测相应肌肉的MP丧失程度,可为尺神经损伤的法医学鉴定提供可靠证据。
Objective To evaluate the value of motor nerve conduction velocity （MNCV） tests for ulnar nerve injury and correlations between measurements related to MNCV tests and muscle power （MP） for medicolegal expertise. Methods 25 patients with ulnar nerve injury and 25 healthy persons with similar age were studied, and the results of their MNCV between two groups were compared. Main tested index included latency, wave amplitude and MNCV. Their MP （including muscle of hypothenar, first interosseus and flexor carpi ulnaris） were also examined by the same operator. Results Significantly difference was found between two groups. Correlation analysis suggests that MP was correlated with MNCV and wave amplitude in patients group. Conclusion Ulnar nerve injury can be proved by MNCV test, rank of MP loss after ulnar nerve injury also can be predict by this test. Therefore MNCV test is a powerful tool for ulnar nerve injury expertise.
