March 9, 2026·34 min·1 clip

Pain Unfiltered podcast Season 3 finale featuring Drs. Jason Pope and Jonathan Goree discussing Saluda Medical's physiologic closed-loop spinal cord stimulation technology (ECAP/EVA).

Experts compare cervical vs. thoracic dosing, discuss durability improvements over traditional open-loop SCS, and debate whether closed-loop stimulation will become the future standard of care.
