ELECTRICAL CONDUCTION BLOCK IN LARGE NERVES: HIGH-FREQUENCY CURRENT DELIVERY IN THE NONHUMAN PRIMATE

Recent studies have made significant progress toward the clinical implementation of high-frequency conduction block (HFB) of peripheral nerves. However, these studies were performed in small nerves, and questions remain regarding the nature of HFB in large-diameter nerves. This study in nonhuman primates shows reliable conduction block in large-diameter nerves (up to 4.1 mm) with relatively low-threshold current amplitude and only moderate nerve discharge prior to the onset of block.
