8. Neurophysiological comparison among tonic, high frequency and burst spinal cord simulation: Novel insights into spinal and brain mechanisms of action

Spinal cord Stimulation (SCS) is an effective option for neuropathic pain treatment. New technological developments, as high-frequency (HF) and Theta Burst Stimulation (TBS), have shown promising results, although putative mechanisms of action are still debated.Twenty-five patients with lower back pain were enrolled and underwent LF, HF and TBS. LEPs were recorded by using a Nd:YAG laser: amplitudes and latencies of the main two components (N1, N2/P2) were compared among different experimental conditions.
