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.
