Superficial peroneal nerve conduction studies for electromyographic diagnosis.Muscle Nerve. 1986 May; 9(4):322-6.MN
A new standardized surface technique for conduction studies of the superficial peroneal nerve was developed and applied to 35 normal subjects and 63 patients with peroneal mononeuropathies, lumbar radiculopathies, sciatic neuropathies, lumbosacral plexopathies, or peripheral neuropathies. The response amplitude was greater than 5 microV and the response peak latency was less than 4.1 msec in all normal subjects; however, 8.6% of normal subjects had at least one unelicitable superficial peroneal nerve response (6% of all limbs tested). These data were compared with those of previous studies. Although this technique did not improve the diagnosis of peroneal neuropathy, it did distinguish lumbosacral plexopathy and sciatic neuropathy from L5 radiculopathy and served as a second, easily approachable, sensory conduction study of the leg.
