The motor nerve conduction velocities of n. medianus, n. ulnaris, n. tibfalis and n. peronaeus were compared with the nerve conduction velocities measured after the definition of the shortest F wave latency in the same nerves in 62 subjects with alcoholic neuropathy of different degrees and in 81 healthy persons.

The sensory nerve conduction velocities of n. suralis as well as the form and size of the F wave amplitude of the motor sum potentials and the sensory nerve action potentials were examined and compared in the groups of healthy and alcoholic persons.

The results showed that the average nerve conduction velocity, defined through the F waves, was lower in comparison to the motor nerve conduction velocity in all 4 nerves in the alcoholic subjects.

It was also remarkable that in the 39 alcoholic persons, when a low sensory nerve conduction velocity of n. suralis was found, the difference between the motor nerve conduction velocity and the nerve conduction velocity defined through the F waves in the other 4 nerves was most evident.

The amplitudes of the F waves, the motor sum potentials and the sensory nerve action potentials were lower in the alcoholic subjects than in the healthy ones.
