Determinants for Meaningful Clinical Improvement of Pain and Health-Related Quality of Life After Spinal Cord Stimulation for Chronic Intractable Pain

Association Between Pain Scores and Successful Spinal Cord Stimulator Implantation

“…This result agrees with similar research done by Murphy et al, which showed that female gender was associated with a 13% higher probability of successful conversion of SCS trial in a multivariate analysis, controlling for age, comorbidity, implant volume, year, insurance, and employment status . Another study of 34 patients by Campos et al also found that female gender was significantly associated with a higher chance of meaningful clinical improvement in physical role function after SCS (OR = 6.4, p = 0.02) . Multiple studies have demonstrated significantly increased response to epidural SCS in female patients for a variety of intractable pain syndromes, including FBSS and cancer‐related pain .…”

Pain Catastrophizing Does Not Predict Spinal Cord Stimulation Outcomes: A Cohort Study of 259 Patients With Long-Term Follow-Up

“…However, in SCS patients, the current evidence of an association between baseline PCS scores and SCS outcomes is equivocal, with published studies having small sample sizes or showing mixed results (9‐13). Therefore, the aim of this cohort study is to investigate if baseline PCS scores can predict SCS outcomes in 259 permanently implanted SCS patients having a follow‐up duration between six months and nine years (median = three years).…”

Predictors of Pain Recurrence After Lumbar Facet Joint Injections

“…Paired-samples “ t ” tests analyzed comparisons between the mean (SD) scores of VAS and ODI scales before and 6 months after FJI. We determined that the amount of change in the VAS and ODI scales by the difference between post-minus pre-surgical scores of VAS and the ODI scales, and the amount of change in VAS and ODI scores to be considered clinically significant were determined based on patient-centered estimation as previously described by our group (Campos et al, 2019). Therefore, we calculated the mean (SD) and the confidence interval of 95% (CI 95%) of the difference between the post-minus pre-surgical scores in the VAS and the ODI scales for each group of patients divided according to the MacNab category of global effectiveness.…”

“…Therefore, we calculated the mean (SD) and the confidence interval of 95% (CI 95%) of the difference between the post-minus pre-surgical scores in the VAS and the ODI scales for each group of patients divided according to the MacNab category of global effectiveness. The inferior limit of the CI 95% of VAS and ODI scales calculated for the group of patients reporting MacNab criteria of good or excellent global effectiveness after the SCS was used to establish the amount of change in pain and disability necessary to be considered clinically significant (Campos et al, 2019).…”

“…For this motive, a therapy as the FJIs may not resolve this pain disorder completely. Recently, there has been an increase in findings on the psychosocial aspects (e.g., depression, catastrophizing, pain sensitivity) as predictors for surgical outcomes among patient with chronic pain (Flor and Turk, 1989; Khan et al, 2011; Campos et al, 2019).…”
