Conduction velocity from spinal cord to axilla (estimated using the F wave) has been compared with conduction velocity from axilla to wrist (measured in the conventional manner) in the motor fibres of the ulnar nerve in 17 controls subjects and in 11 patients with the Guillain-Barré syndrome (GBS). In the patients with GBS the conduction velocity was, in general reduced to a similar extent in both the proximal and the distal portions of the motor fibres, suggesting that the disease process is usually diffuse. In two patients, however, the conduction velocity in the proximal segment was disproportionally reduced and in one of these the conduction velocity in the distal segment was normal. It is concluded that the estimation of conduction velocity in the proximal segments of motor nerves may be of value in the assessment of patients with GBS.
在17名对照受试者和11名吉兰 - 巴雷综合征(GBS)患者的尺神经运动纤维中,已将从脊髓到腋窝的传导速度(使用F波估计)与从腋窝到手腕的传导速度(以传统方式测量)进行了比较。在GBS患者中,运动纤维近端和远端的传导速度通常都降低到相似程度,这表明疾病过程通常是弥漫性的。然而,在两名患者中,近端节段的传导速度不成比例地降低,其中一名患者远端节段的传导速度正常。得出的结论是,运动神经近端节段传导速度的估计在GBS患者的评估中可能具有价值。
