[Conduction velocity changes in peripheral nerves in the acute stage of the Guillain-Barre syndrome].
In 20 cases of acute Guillain-Barré syndrome (including 4 recurrent cases the conduction velocity was measured in the nerves: facial, axillary, musculocutaneous, peroneal, sural and ulnar (motor and sensory). In the long nerves the maximal as well as minimal conduction velocity was determined. At the peak of development of clinical manifestations all electrophysiological parameters differed from the normal values, in particular, significant changes were found in long nerves (complete parallelism was found between the velocity of conduction and end latency). In the first stage of regression of clinical manifestations the electrophysiological parameters continued to show an increased abnormalities, only later they approached the normal values. Sensory conduction was disturbed in an equal degree as the motor conduction despite absence of clinical sensory disturbances. In recurrent cases slowing down of conduction was much more striking and persisted also during remission. In all studied cases independently of the character and course of the disease there was no correlation between the clinical state and the changes in the determined electrophysiological parameters.
