Pain related potentials by electrical stimulation of skin for detection of small-fiber neuropathy in HIV.
We compared the sensitivity of pain related evoked potentials (PREP), a novel electrophysiological technique, with standard nerve conduction (SNC) testing in the diagnosis of small fiber neuropathy in 47 patients with HIV infection and 31 age matched controls. SNC testing revealed a neuropathy in only 31%, whereas PREP was abnormal in 74% of symptomatic patients. This result hints that PREP is more sensitive in the detection of HIV-associated small fiber neuropathy than standard neurography.
