It would be desirable to identify patients with acute low back pain (ALBP) who are at high risk for transition to chronic pain early in the course of their disease. This would enable early preventive or therapeutic interventions. Patients with chronic low back pain (CLBP) display signs of central hypersensitivity. This may contribute to the transition to CLBP. We tested the hypothesis that central hypersensitivity as assessed by quantitative sensory tests predicts transition to CLBP. ⋯ We found no evidence to support a clinically relevant ability of current quantitative sensory tests to predict the transition from acute to CLBP.

Controlled Clinical Trial
Assessing the efficacy of a manual-based intervention for improving the detection of facial pain expression.
This article presents the results of a parallel-group, non-randomized, controlled study that evaluated the feasibility of an online training program for improving observer detection of facial pain expression. ⋯ The index of facial pain expression (IFPE) is an online training program that can improve an observer's ability to reliably detect expressions of clinical pain after as few as 3.5-hr of training.

Observational Study
Spinal cord stimulation for chronic refractory pain: long-term effectiveness and safety data from a multicentre registry.
Spinal cord stimulation (SCS) is an established therapy for refractory neuropathic pain. To ascertain the balance between treatment benefits and risks, the French National Authority for Health requested a post-market registry for real-world evaluation of the long-term effectiveness and safety of the therapy. ⋯ This observational, prospective study in a real-life setting followed a large cohort of patients suffering from chronic pain and implanted with SCS devices in France. The study assessed the long-term effectiveness and safety of SCS therapy in a representative sample of implanting sites in France.

Within the Fear Avoidance Model of pain, quantitative neurophysiological factors provide additional conceptual benefit when integrated along with traditional psychologically aspects of the FAM.
