Sensory evoked potentials were obtained in 45 patients with adult-onset progressive spastic paraparesis and no clinical evidence of disease outside the spinal cord. Abnormalities in somatosensory evoked potentials documented subclinical dysfunction of the dorsal column-lemniscal system in 17 patients. Stimulation of both upper and lower extremities was necessary to maximize the incidence of abnormal findings. Visual evoked potentials were abnormal in 76% of patients with probable multiple sclerosis. Evoked potential studies were normal in patients with motor neuron disease. We conclude that sensory evoked potentials are useful in the evaluation of patients with an undiagnosed progressive myelopathy of late onset.
