10‐Khz spinal cord stimulation for chronic postsurgical pain: Results from a 12‐month prospective, multicenter study
Pain Practice Jul 27, 2020
Gupta M, Scowcroft J, Kloster D, et al. - Via this prospective, single‐arm study, researchers sought to describe the effectiveness of 10‐kHz spinal cord stimulation (10‐kHz SCS) as a treatment for patients with chronic postsurgical pain (CPSP). In individuals with CPSP who were refractory to conventional medical interventions and had pain scores of ≥ 5 cm on a 10‐cm VAS, trial stimulations lasting up to 14 days were performed. Implantation of epidural leads was done at locations relevant for the primary area of pain, and trials resulting in ≥ 40% pain relief were considered successful. A permanent 10‐kHz SCS system was implanted in individuals with successful trials and follow up was performed for 12 months after implantation. Among 34 recruited individuals in trial stimulation, early withdrawal was reported for 1 and there were 29 (87.9%) who had a successful trial and received a permanent implant. Over the course of the study, improvement was reported in pain catastrophizing and vigilance, patient function, physical and mental well‐being, and sleep quality. Further, there were no neurologic deficits in the study. Per these findings, 10‐kHz SCS is effective and tolerated in patients with CPSP.
