DSSEPs results from a 51-year-old male in the EI/FI group. The DSSEPs were performed at cervical neutral (A), 20° extension (B) and 35° flexion (C) positions for a patient. The latencies of N9, N13 and N20 waves and the amplitudes of N13 and N20 waves are shown in the figure. The patient’s DSSEP N13 amplitude improved by 58.1 and 20.7% at extension and flexion positions respectively compared to the neutral position, meeting the criteria for entering both EI and FI groups (> 20%)
