SEPs obtained by stimulation of the median nerve of the wrist were recorded in a group of 33 subjects working with vibrating instruments in 82% of whom the case history was positive for Raynaud's Phenomenon (RP). Electrophysiological investigation revealed a decrease in peripheral nerve conduction speed, which was related to the duration of exposure to risk and the presence of RP. No diseases of the central nervous system were found. The results are discussed on the basis of the data in the literature.
