[Radial nerve potential at the wrist of man].

Radial nerve potential was studied at the level of the wrist in 13 normal subjects. Simultaneous recording at the level of the median nerve potentials and of a block of its conduction showed that median activity spreads to the area of recording of radial potentials. However, the radial latency is shorter so that potentials of each nerve can be distinguished. This technique could be applied in current practice.
