Enhancement of voluntary motor function following spinal cord stimulation--case study

Abstract

One patient with an incomplete traumatic myelopathy underwent epidural spinal cord stimulation for the management of severe intractable spasms, which were abolished by the stimulation. After several months of stimulation, the patient regained some voluntary motor function in the lower extremities. Voluntary motor control of the left quadriceps was present only when spinal cord stimulation was activated and stopped immediately after it was turned off. The effects could be consistently reproduced. EMG polygraphic recordings confirmed the results.
