Methods: EMG of 80 patients with PM and DM were analyzed including fibrillation, mean duration of MUP, mean amplitude of MUP, polyphasic, recruitment pattern of maximum voluntary contraction, NCV and musele biopsies.

方法：分析80例多发性肌炎、皮肌炎患者肌电图检查中自发电活动，MUP时限、波幅及多相波，最大随意收缩时的募集形式，以及NCV检查及肌肉活检资料。

Results The NCV showed mainly conduction velocity decreased, amplitude reduced.

结果GBS的NCV异常主要表现为传导速度减慢，波幅降低。

Methods NCV and EMG were examined on 49 patients of chronic phosphine poisoning.

方法对49例慢性磷化氢中毒的患者进行NCV和EMG检测。结果纤颤电位出现率为9.7%，正锐波8.2%；

Collect there general information, history, clinical signs and EMG+ NCV results.

采集受试者的一般情况、病史、体征和EMG+NCV结果。

Results The NCV, NFC and morphologic study of regenerated myelin and CMAP were all better in group C than in group B ( P < 0.01) 8 and 16 weeks postoperatively, but not up to Group A.

结果C组在术后8周及16周时，再生神经的NCV、NFC、纤维形态、支配肌肉的CMAP等指标均优于B组（P<0.01），但不如A组。

Methods: The nerve conduction velocity ( NCV) and QST were examined in 136 diabetic patients and 118 normal controls, and their results were compared.

方法：应用QST仪检测118名正常人与136例DPN病人的冷觉（CS）、热觉（WS）和振动觉（VS）阈值及神经传导速度（NCV）。

NCV in the group without PLDD was significantly lower than that in the sham group ( P < 0.001 ).

治疗组神经传导速度显著快于非治疗组 ( P<0.001 ).

No abnormal electrophysiological changes was appeared on 6 patients of 10 with only SCLC.

2在10例单纯SCLC患者 中,6例EMG、 NCV、SEP无明显异常.

NCV was decreased with an abnormality rate of 25 %-65 %.

结果显示NCV较正常组减慢,异常率为25%～65%.
