Conductivity in Elastically Stretched and Relaxed Spinal Cord Evaluated by Somatosensory Evoked Potentials
The effect of neck flexion and extension on early components of the tibial nerve cortical evoked potential was studied in healthy subjects and in multiple sclerosis and scoliosis patients. No significant latency differences were demonstrated, and there was consequently no evidence of an acute decrease of cord conductivity produced by stretching of axons during flexion.
