cmct

Measurement of central motor conduction time ( cmct ) in healthy Chinese subjects

正常中国人中枢运动系统传导时间的测定

F waves and M waves were also recorded to calculated the central motor conductive time ( CMCT ) .

同时检测F波和M波计算中枢运动传导时间（centralmotorconductivetime，CMCT）。

Conclusion : In extramedullary lesion , measurement of CMCT to the AT is more sensitive .

结论：在髓外病变，AT肌CMCT较为敏感；

Prolonged latency , lowed amplitude and shortened CMCT in MEP suggest the damage of the neurons .

GD患者MEP潜伏期延长、波幅降低及CMCT缩短，提示GD患者神经元有损害。

Results : The latency of cortical and centra motor conduction time ( CMCT ) of motor evoked potential of ( MEP ) in MND patients were longer than those of the controls .

结果：MND组mMEP皮层潜伏期和中枢运动传导时间（CMCT）均明显长于对照组；

Results All 30 patients had abnormal MEPs and manifested by elongation of cortical latency and central motor conduction time ( CMCT ), widened CMAPs duration as well as decreased amplitude or disappeared MEP .

结果全部病人的MEP都出现异常，表现为潜伏期、中枢传导时间（CMCT）延长，时限增宽，波辐降低或不能引出。

Excitability of the motor cortex were assessed by rest threshold ( RT ), central motor conduction time ( CMCT ), central silent period ( CSP ) and amplitude of motor evoked potential ( MEP ) .

采用静息态阈值（RT）、中枢传导时间（CMCT）、中枢静息期（CSP）和运动诱发电位（MEP）的波幅作为评定大脑皮质兴奋性的指标。

Results : The respective latent periods of the MEPs and the CMCT were all lengthened in the 12 patients . There was a significant difference compared with ttat of the control group ( P < 0.05 ) .

结果：12例高位颈髓损伤患者受伤后各时间段的膈肌MEP皮层潜伏期及中枢传导时间（CMCT）均延长，与对照组相比差异有显著性（P<0·05）。

Results : The abnormality rate of MEP during acute stage was 93 % with disappearance of cortical components , prolongation of central motor conduction time ( CMCT ), abnormality of waveforms and an increases in threshold stimulation intensity .

结果：急性期MEP的异常率为93%，主要表现为皮层MEP消失，中枢运动传导时间（CMCT）延长，波形异常及阈刺激强度增高。

Magnetic motor evoked potentials ( MEP ) were measured in 46 patients with Graves ′ disease ( GD ) and 50 normal controls , and its latency 、 amplitude and central motor conduction time ( CMCT ) were recorded .

应用磁运动诱发电位（MEP）检测46例Graves（GD）病患者和50名正常对照组MEP潜伏期、波幅及中枢运动传导时间（CMCT）。

Method : Magnetic stimulation of motor cortex with F wave recording was used to assess central motor conduction time ( CMCT ) and central somatosensory conduction time ( CSCT ) was evaluated by SEPs in 20 patients suffering from cervical spondylotic myelopathy .

方法：对20例影像学或手术证实的脊髓型颈椎病病人进行磁刺激MEPs与F波结合测定CMCT及SEPs的中枢感觉传导时间（CSCT）。

Methods To record the latency and amplitude of diaphragmatic compound muscle action potential ( DCMAP ) from 37 ALS patients and 31 control subjects with surface electrodes after transcranial and transcervical magnetic stimulation , central motor conduction time ( CMCT ) was calculated .
