Meta Analysis
Relationship between psychological factors and spinal motor behaviour in low back pain: a systematic review and meta-analysis.
This meta-analysis investigated whether more negative psychological factors are associated with less spinal amplitude of movement and higher trunk muscle activity in individuals with low back pain. Furthermore, it examined whether pain intensity was a confounding factor in this relationship. We included studies that provided at least 1 correlation coefficient between psychological (pain-related fear, catastrophizing, depression, anxiety, and self-efficacy) and spinal motor behaviour (spinal amplitude and trunk muscle activity) measures. ⋯ Pain intensity did not significantly affect the association between these psychological factors and spinal motor behaviour and had a very small independent association with spinal motor behaviour. In conclusion, the very small effect sizes found in the meta-analyses question the role of psychological factors as major causes of spinal movement avoidance in low back pain. Experimental studies with more specific and individualized measures of psychological factors, pain intensity, and spinal motor behaviour are recommended.

The STarT Back approach comprises subgrouping patients with low back pain (LBP) according to the risk of persistent LBP-related disability, with appropriate matched treatments. In a 12-month clinical trial and implementation study, this stratified care approach was clinically and cost-effective compared with usual, nonstratified care. Despite the chronic nature of LBP and associated economic burden, model-based economic evaluations in LBP are rare and have shortcomings. ⋯ Sensitivity analyses indicate the approach is likely to be cost-effective in all scenarios and cost saving in most. It is likely this stratified care model will help reduce unnecessary healthcare usage while improving the patient's quality of life. Although decision-analytic modelling is used in many conditions, its use has been underexplored in LBP, and this study also addresses associated methodological challenges.

Aim: Low back pain is a leading cause of patient disability in the USA. Our goal was to determine association between patient characteristics and their response to lumbar medial branch block, radiofrequency ablation of medial nerves or lumbar facet joint injections. ⋯ Results: At the 3-month post-procedure visit, positive responders were significantly more likely to be non obese patients (BMI <30) and those with pain <5-years. Conclusion: Obesity and chronicity of pain certainly are found to be predictors of response to the above mentioned procedures.

Single-center prospective non-randomized matched cohort comparison. ⋯ The SSP facilitates significantly shorter wait times for MRI and promotes nonoperative treatment strategies. Preoperative patient satisfaction is significantly higher among SSP patients, but there were no significant differences in surgical outcomes.Level of Evidence: 3.

Pain originating from the posterior sacroiliac complex is notoriously difficult to effectively treat due to its complex anatomy and variable innervation. Data on radiofrequency ablation (RFA) is limited. The Abbott Simplicity probe creates 3 monopolar lesions along the medial aspect of the sacroiliac joint and 2 bipolar lesions between the active portions of the probe. This device has been studied previously with improvement of pain-associated disability and pain reduction, but insufficient data is present to determine its utility at this time. Using the most recent literature for the potential innervation of the posterior sacroiliac joint, it is reasonable to explore this novel device and its ability to treat sacroiliac joint pain. ⋯ Radiofrequency ablation of the posterior sacroiliac complex with the Simplicity probe resulted in more functional improvement than analgesia. This study provides more data for clinicians to utilize in managing posterior sacroiliac complex pain. IRB: Protocol number 20170342HU. Not registered in clinical trials.
