Motor-evoked potentials in a child recovering from transverse myelitis.
We describe a 13-year-old female, with an inability to walk because of transverse myelitis, who demonstrated progressive recovery of both motor function and motor- evoked potentials (MEP). At 4 weeks after onset, amplitudes of MEP were decreased, latencies were prolonged, and cortical somatosensory-evoked potentials (SEP) were absent. At 6 and 12 weeks, MEP revealed progressively higher amplitudes and shorter latencies. SEP also recovered. MEP and SEP recovery paralleled clinical recovery. MEP in response to transcranial magnetic stimulation may provide guidance regarding recovery from spinal cord disorders in children.
