Randomized Controlled Trial
Efficacy of Cabbage Leaf Wraps in the Treatment of Symptomatic Osteoarthritis of the Knee: A Randomized Controlled Trial.
Osteoarthritis (OA) of the knee is one of the most common chronic diseases among older adults. This study aimed to test the effects of cabbage leaf wraps (CLWs) in the treatment of symptomatic OA. ⋯ CLWs are more effective for knee OA than UC, but not compared with diclofenac gel. Therefore, they might be recommended for patients with OA of the knee. Further research is warranted.

Randomized Controlled Trial Multicenter Study
Randomized Sham-controlled Double-Blind Multicenter Clinical Trial to Ascertain the Effect of Percutaneous Radiofrequency Treatment for Sacroiliac Joint Pain: Three-month Results.
To investigate the effect of a percutaneous radiofrequency (RF) heat lesion compared with a sham procedure, applied to the lateral branches of L5, S1, S2, S3, and S4 nerve roots. ⋯ Level 1A.

Randomized Controlled Trial
Efficacy of Pregabalin in the Treatment of Prediabetic Neuropathic Pain.
We report the results of a pilot, enrichment-design, placebo-controlled crossover trial of pregabalin for the treatment of prediabetic small-fiber neuropathic pain. ⋯ This pilot study showed improvement of prediabetic neuropathic pain. Participants with higher pain scores at baseline had higher UENS scores and a lower IENFD. Limitations of the study include the small number of participants and the carry-over effect.

Randomized Controlled Trial
Development and Validation of the Behavioral Avoidance Test - Back pain (BAT-Back) for Patients with Chronic Low Back Pain.
Pain-related fear and avoidance of physical activities are central elements of the fear-avoidance model of musculoskeletal pain. Pain-related fear has typically been measured by self-report instruments. In this study, we developed and validated a Behavioral Avoidance Test (BAT) for chronic low back pain (CLBP) patients with the aim of assessing pain-related avoidance behavior by direct observation. ⋯ Results indicate that the BAT-Back is a reliable and valid measure of pain-related avoidance behavior. It may be useful for clinicians in tailoring treatments for chronic pain as well as an outcome measure for exposure treatments.

Low back pain (LBP) is the second most frequently diagnosed pain condition in the United States, and although a majority of individuals have resolution of pain during the acute period, an estimated 40% of individuals will experience persistent pain. Given the heterogenous nature of LBP, this study sought to describe and compare somatosensory and molecular (gene expression) profiles between individuals with acute LBP and healthy no-pain controls. ⋯ Acute LBP participants showed selective pain sensitivity enhancement and differential gene expression profiles compared with pain-free controls. Further research to characterize pain-associated somatosensory changes in the context of altered mRNA expression levels may provide insight on the molecular underpinnings of maladaptive chronic pain.
