Is is possible to know when to operate on a syrinx before the spinal cord is damaged enough to cause significant weakness?
The authors of a recent study feel that electrophysiological testing to evaluate the silent period is more sensitive to change in neurological integrity within the spinal cord in persons with syrinx. Somatosensory evoked potentials and motor evoked potentials may be normal and not detect more subtle, early changes that silent period testing can.
