“…This scale is anchored at 0 representing “no pain” and 10 representing “worst imaginable pain.” Each number on this 11-point scale has a functional description; for example, a 3 on the scale is “Pain that is starting to affect your ability to perform the current activity,” and a 7 on the scale is “You cannot use or move the painful area. You have difficulty talking and concentrating on anything but the pain.” While initially validated only among the elderly, 13 a recent study 14 reported adequate reliability and validity of a modified version in a sample of patients with chronic pain. FPS data were extracted at three time points for all subjects and the initial point value was used for propensity matching ( Figure 1 ).…”

ObjectiveTo evaluate clinical outcomes and health care utilization at 12 months post spinal cord stimulator (SCS) implantation compared with baseline and a matched sample of patients receiving conventional medical management (CMM) for the treatment of low back and lower extremity pain.PatientsA retrospective study of patients with at least 24 months of active treatment at an interdisciplinary community pain center between December 1, 2014 and December 31, 2017. Thirty-two patients receiving implantation of a high-frequency (10 kHz) SCS and 64 patients receiving CMM were identified through propensity matching at a ratio of 2:1.MethodsData were extracted from medical records, including pain severity, prescribed opioid dose in morphine milligram equivalents, patient perception of disability, and volume of interventional pain procedures and total office visits to the pain center.ResultsReductions in opioid dose were significantly greater for the SCS group than the CMM group. The 26.2 mg morphine equivalent dose reduction represents a 28% reduction from baseline, with 71.4% of those prescribed opioids in the SCS group reducing their dose at 12 months post-implant. Among those with SCS, there were significant within-group reductions in numerical pain score for low back and lower extremity pain, reducing by 46.2% and 50.9% from baseline, respectively. Change in functional pain score was not significant for either SCS group or CMM. Both groups had significant within-group reduction in disability. Reduction of interventional procedure volume was significant for both groups with a greater reduction observed in the SCS group. Office visit volume reduction was significant for the CMM group, but this was not a significant difference from the SCS group.ConclusionsResults support the efficacy of 10 kHz SCS for analgesia, reduction of opioid utilization, reduction of interventional pain procedures, and patient perception of disability.
