Pain-Related Vertex Evoked Potentials. Comparison of Surface Electrical to Heat Stimulation.


Guiloff RJ, Campero M, Barraza GR, Treede RD, Matamala JM, Castillo JL


Demonstration of nociceptive fiber abnormality is important for diagnosing neuropathic pain and small fiber neuropathies. This is usually assessed by brief heat pulses using lasers, contact heat, or special electrodes. We hypothesized that pain-related evoked potentials to conventional surface electrical stimulation (PREPse) can index Aδ afferences despite tactile Aß fibers coactivation. PREPse may be more readily used clinically than contact heat evoked potentials (CHEPS).
