In some definite patients, a standard neurophysiological tool may not solve a complete differential diagnosis in common nerve peroneal neuropathy. In this study we have assessed a new simple procedure to study the orthodromic sensory conduction of both the superficial peroneal nerves (SPN) and deep peroneal nerves (DPN) in a heterogeneous group of 55 normal subjects. The mean sensory orthodromic conduction velocity of the SPN was 58.35 m/s. The mean sensory orthodromic conduction velocity of the mixed nerve action potential (MNAP) of the DPN was 55.27 m/s. The sensory conduction velocity, the amplitude of sensory-evoked potentials of SPN and DPN across the fibular head and the normative values are discussed. Our results confirm that these recording methods are easy to repeat and reliable in identifying peroneal neuropathy.
