Intraoperative setup showing the positioning of the bipolar electrode (white arrow) with the filum lifted on a hook and the underlying cauda equina insulated with a dry cotton (black arrow). Electrophysiological recordings of paraspinal muscles: lowest stimulus intensity at which the paraspinal muscles were activated (n = 22), latency between stimulus and muscle response, and compound muscle activation potential CMAP of the paraspinal muscles. CMAP, compound muscle action potential.
