[Somatosensory evoked potentials: clinical applications in peripheral neuropathies].
Somatosensory evoked potentials (SSEP) offer a reliable measurement of peripheral and central sensory conduction through the stimulation of mixed or purely sensitive nerves. If their interest is well known for the evaluation of central pathologies (cerebral or spinal), their precise indication and application field in peripheral neuropathies remains unclear. Some specific diseases, like lumbar or cervical radiculopathies or brachial plexopathies, have been extensively studied and large series have been reported in the literature. Relative sensitivity and specificity of SSEPs and electroneuromyography (ENMG) is a matter of debate for specific peripheral nerve affections. We present a practical approach in which SSEPs and ENMG data are integrated toward a better diagnosis. Clinical histories are exposed as an illustrative demonstration of specific interest for combined SSEPs and ENMG in the patient's functional evaluation and follow-up.
