Randomized Controlled Trial
Effects of attentional bias modification on chronic low back pain in older outpatients: A randomized crossover trial (pilot study).
In the present study, the effect of attentional bias modification (ABM) on older outpatients, with chronic low back pain, was examined. ⋯ There was no change in pain intensity due to ABM. However, the total Pain Catastrophizing Scale score was significantly decreased, and the EuroQol 5 Dimension-3 levels questionnaire and 30-second chair-stand test were significantly improved (P <.05).

Background and Objectives: Chronic lower back pain (LBP) is a common clinical disorder. The early identification of patients who will develop chronic LBP would help develop preventive measures and treatment. We aimed to develop machine learning models that can accurately predict the risk of chronic LBP. ⋯ The LR, KNN, NB, DT, RF, GBM, SVM, and ANN models showed performances (in terms of AUROCs) of 0.656, 0.656, 0.712, 0.671, 0.699, 0.660, 0.707, and 0.716, respectively, with ten-fold cross-validation. Conclusions: In this study, the ANN model was identified as the best machine learning classification model for predicting the occurrence of chronic LBP. Therefore, machine learning could be effectively applied in the identification of populations at high risk of chronic LBP.

Background and objectives: The influence of changes in spinal alignment after total hip arthroplasty (THA) on improvement in lower back pain (LBP) remains controversial. To evaluate how changes in spinal malalignment correlate with improvement in preoperative LBP in patients who underwent THA for hip osteoarthritis. Materials and Methods: From November 2015 to January 2017, 104 consecutive patients who underwent unilateral THA were prospectively registered. ⋯ Fourteen (54%) of the 26 patients with preoperative LBP showed pain improvement, but there were no significant differences in the radiographic parameters. Conclusions: Although preoperative LBP was likely to be resolved after THA, there were no significant correlations between alignment changes and LBP improvement. The cause of LBP in patients with hip osteoarthritis (OA) patients might be multifactorial.

Vitamin D deficiency has been linked to nonspecific low back pain (Ns-LBP); however, the role of inflammation as a possible mediator between vitamin D levels and Ns-LBP is not well understood. ⋯ Patients with Ns-LBP had lower vitamin D and higher inflammatory marker levels. This association between hypovitaminosis D and Ns-CLBP may be mediated by IL-6. Therefore, large-scale clinical trials are warranted to investigate the clinical efficacy of vitamin D supplementation for decreasing inflammation and relieving Ns-LBP.

Randomized Controlled Trial
A randomized controlled trial of ibuprofen versus ketorolac versus diclofenac for acute, nonradicular low back pain.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line medication for acute low back pain (LBP). It is unclear if the choice of NSAID impacts outcomes. We compared ibuprofen, ketorolac, and diclofenac for the treatment of acute, nonradicular LBP. ⋯ There were no important differences between groups with regard to the primary outcome. These data do not rule out that possibility that ketorolac results in better pain relief and less stomach irritation than ibuprofen.
