A study by the Non-Invasive Brain Stimulation and Human Motor Control Laboratory at the Burke Medical Research Institute is featured on the cover of the October issue of the journal Spinal Cord.
The researchers—Dylan Edwards, Ph.D., P.T., Mar Cortes, M.D, and Avrielle Rykman, M.A.—report that corticospinal conduction may be preserved after spinal cord injury even in the absence of voluntary movement. Using transcranial magnetic stimulation (TMS), the researchers recorded normal motor-evoked potential in some of the muscles of the forearm in a patient with C5 spinal cord injury. This finding suggests that TMS could help identify promising targets for rehabilitation that may be missed in clinical assessment.
The study was done in collaboration with Gary Thickbroom, Ph.D. of the University of Western Australia, Alvaro Pascual-Leone, M.D., Ph.D., of Harvard Medical School, and Bruce Volpe, M.D. of the Feinstein Institute for Medical Research.
