Activity-based treatments play an integral role in managing musculoskeletal conditions including low back pain. However, while therapeutic exercise has been shown to reduce pain in such conditions, certain individuals experience a paradoxical pain increase in response to exercise. The physiological processes underlying this sensitivity to physical activity (SPA) are not fully understood, however stress and inflammation have been shown to contribute to SPA. The present cross-sectional study investigated whether physiological indicators of stress (cortisol) and inflammation (IL-6) help explain SPA. ⋯ This study reveals a correlation between SPA and an objective salivary biomarker of IL-6 in people with low back pain, improving our understanding of this clinically relevant subjective experience.

Chronic low back pain (CLBP) is one of the most common chronic pain conditions that cause both individual suffering and a burden to society. For these patients, several interventional treatment options such as surgery, blocks, radiofrequency, and spinal cord stimulation are available. Lately, dorsal root ganglion stimulation (DRG-S) also has been mentioned as an option by targeting bilateral T12 dorsal ganglia. In this study, we present the outcome of 11 patients with CLBP treated with bilateral T12 DRG-S. ⋯ Bilateral T12 DRG-S seems to be an effective treatment for chronic low back pain, with significant beneficial effect not only on pain but also on quality of life, pain catastrophizing, mental status, sleeping disorder, and physical activity. 4-Hz DRG-S gave a result comparable with or better than 20-Hz stimulation.

Chronic discogenic low back pain (CD-LBP) is caused by degenerated disks marked by neural and vascular ingrowth. Spinal cord stimulation (SCS) has been shown to be effective for pain relief in patients who are not responsive to conventional treatments. Previously, the pain-relieving effect of two variations of SCS has been evaluated in CD-LBP: Burst SCS and L2 dorsal root ganglion stimulation (DRGS). The aim of this study is to compare the effectivity in pain relief and pain experience of Burst SCS with that of conventional L2 DRGS in patients with CD-LBP. ⋯ The clinical trial registration numbers for the study are NCT03958604 and NL54405.091.15.

Recently, we showed that patients with knee osteoarthritis (KOA) demonstrate alterations in the thalamic concentrations of several metabolites compared with healthy controls: higher myo-inositol (mIns), lower N-acetylaspartate (NAA), and lower choline (Cho). Here, we evaluated whether these metabolite alterations are specific to KOA or could also be observed in patients with a different musculoskeletal condition, such as chronic low back pain (cLBP). Thirty-six patients with cLBP and 20 healthy controls were scanned using 1 H-magnetic resonance spectroscopy (MRS) and a PRESS (Point RESolved Spectroscopy) sequence with voxel placement in the left thalamus. ⋯ Additionally, also in patients, both Cho and mIns levels were positively correlated with age ( P < 0.01 and P < 0.05, respectively). Altogether, these results suggest that thalamic metabolite changes may be common across etiologically different musculoskeletal chronic pain conditions, including cLBP and KOA, and may relate to symptoms often comorbid with chronic pain, such as sleep disturbance. The functional and clinical significance of these brain changes remains to be fully understood.

Observational Study
Low back pain, pelvic pain, and associated factors in type 1 diabetic pregnant women.
Pregnancy and diabetes mellitus promote several musculoskeletal changes predisposing this population to complaints of Lower Back (LB) and Pelvic Pain (PP). ⋯ There was a high frequency of LB and PP related to pregnancy in DM1 pregnant women in the second trimester of pregnancy. The incidence of sexual dysfunction and DM1 duration ≥ 17 years increases the chance that DM1 pregnant women will experience pain. There was no association between anxiety. urinary incontinence and pain in DM1 pregnant women.
