“…The results from these tests can indicate deficit in mixed peripheral nerves, nerve roots, and in the spinal cord and brain (53). A study done by Kraft et al (54) suggests that since SEPs are generated from peripheral nerves, it is difficult to make single root conclusions from the data. SEPs can be useful for the overall investigation of nerve root and rootlet dysfunction (55).…”

“…Electrophysiologic changes usually occur once the condition progresses to conduction block, axon loss, and demyelination of peripheral nerves (41). SEPs are dorsal column dependent and monitor sensory nerve function (54). Because of this, quantitative measurement of motor nerve function often remains normal because of the lack of measurement in the anterolateral column (29).…”

“…These amplitude reductions improved when pressure was removed from the measured stenosed area. In recent years, many studies have been performed to assess the value of SEPs in determining location of disease, prognostic indicators, and therapeutic options (54). In summary, numerous studies have shown SEPs to be useful adjuncts to imaging in the management of LSS.…”

Much like SEPs, DSEPs can detect impaired nerve conduction in multiple segments caused by chronic, low-grade compression (54). The ability of DSEPs to quantitatively measure pain in single nerve roots has advanced the diagnosis of LSS and has been compared to the advancements made in diagnosing distal sensory latency prolongation in CTS.…”

“…Storm et al (61) suggests that DSEPs allow physicians to diagnose LSS well before symptoms occur, allowing therapeutic intervention in early stages of LSS. These advancements allow for more efficient diagnosis and treatment of LSS and also give a better understanding of patients with neurogenic compromise (54). Because of this, physicians are better able to determine which patients are more suited for surgical intervention (54).…”

S Su um mm ma ar ry yLumbar spinal stenosis (LSS) is a narrowing of the spinal canal and/or the neuroforamina through which the spinal cord roots enter and exit. The symptoms of LSS usually begin over the course of several months and include neurogenic claudication. This is characterized by low back pain that radiates down one or both legs producing pain or weakness. LSS can be quite debilitating and can have a profound negative effect on one's activities of daily living and overall quality of life. Imaging studies, such as computed tomography (CT) and magnetic resonance imaging (MRI) are routinely performed in the work-up of suspected LSS. In recent years, there has been much controversy over the actual clinical usefulness of these studies. When compared to electrodiagnostic studies, CT and MRI have been shown to have increased false negative and false positive rates. Electrodiagnostic studies show dynamic physiological neural function and has become a valuable tool in LSS. This information can be used to determine the location and severity of LSS, differentiate LSS from other conditions, and monitor the progression. Electrodiagnostic techniques such as somatosensory evoked potentials, dermatomal somatosensory evoked potentials (DSEPs), and paraspinal mapping (PM) increase both the sensitivity and specificity in diagnosing LSS. DSEPs provide useful information on multi-level, multiple rootlet disease. PM reflects the physiology of nerve roots and has been found to be superior to extremity needle EMG. Electrodiagnostic techniques are becoming the standard in the diagnosis and therapeutic decisions for LSS and other related diseases.Turk J Phys Med Rehab 2010;56:75-80.

Different neurophysiological methods such as evoked potentials (EP), testing of the autonomic nervous system (ANS) or polysomnography have the potential to detect clinically silent lesions or to confirm the existence of an association between a clinical symptom and multiple sclerosis (MS); previously undetected by MRI. Therefore, in the most recent MRI criteria for the diagnosis of MS (MAGNIMS consensus guidelines), neurophysiological confirmation of optic nerve dysfunction (slowed conduction on visual EP), support dissemination in space and, in patients without concurrent visual symptoms, dissemination in time. In this chapter we will review the existing evidence regarding the role of different neurophysiological tests (specifically the role of EPs, autonomic nervous system testing and sleep testing in MS) in the diagnosis and management of MS.
