Answer

Few studies have evaluated the role of EP changes in acute transverse myelitis. Misra et al assessed 10 patients who had lower-limb and upper-limb weakness by using detailed clinical, MRI, and neurophysiologic evaluation in conjunction with median and tibial SEPs, upper- and lower-limb MEPs, and concentric needle EMG; they found that MRI and MEPs were useful in assessing clinical outcome but that SEP played only a limited role.
