Randomized Controlled Trial
Who Benefits the Most From Different Psychological Chronic Pain Treatments? An Exploratory Analysis of Treatment Moderators.
Different psychological chronic pain treatments benefit some individuals more than others. Understanding the factors that are associated with treatment response-especially when those factors differ between treatments-may inform more effective patient-treatment matching. This study aimed to identify variables that moderate treatment response to 4 psychological pain interventions in a sample of adults with low back pain or chronic pain associated with multiple sclerosis, spinal cord injury, acquired amputation, or muscular dystrophy (N = 173). ⋯ If additional research replicates the findings, it may be possible to better match patients to their more individually suitable treatment, ultimately improving pain treatment outcomes. PERSPECTIVE: Pre-treatment measures of hypnotizability and EEG-assessed brain activity predicted who was more (or less) likely to respond to different psychological pain treatments. If these findings are replicated in future studies, they could inform the development of patient-treatment matching algorithms.

This study examined the association between physiotherapy utilization and subsequent medical healthcare utilization and costs in a population-based sample of adults with back pain in Ontario. We conducted a population-based cohort study of Ontario respondents with back pain (≥18 years) of the Canadian Community Health Survey 2003 to 2010 cycles, linked to health administrative data up to 2018. Physiotherapy utilization was defined as self-reported consultation with a physiotherapist in the past 12 months. ⋯ Adults with back pain who received physiotherapy are more likely to have back pain-specific physician visits up to 5-year follow-up than those who did not. Physiotherapy utilization is linked to some sex-based differences in all-cause healthcare utilization but not differences in costs. Findings inform interprofessional collaboration and allied healthcare delivery for back pain in Ontario.

Pulsed radiofrequency (PRF) has been used for treatment of chronic pain in several body regions, including axial and radicular pain. However, a limited number of reports have specifically demonstrated the effectiveness of PRF for spine-related pain among nonsurgical patients. Therefore, we evaluated the effectiveness of PRF for lumbar spine-associated pain in patients without recent spine surgery, and identified the factors associated with clinically meaningful improvement in pain and quality of life. ⋯ Our results demonstrated that PRF improved pain and patient-reported outcomes for spine-related pain for at least 6 months in our patient cohort. PRF may be a good option for treating lumbar spine-related issues, even with severe pain and/or dysfunction.
