To analyze and characterize the intake profile of pain-relief drugs in a population-based study of adults with chronic low back pain (CLBP). ⋯ Analgesic/pain-relief drug intake in patients with active CLBP was very low, even for those with severe pain. The WHO analgesic ladder was carefully followed, with an extremely conservative use of analgesic opioids even for those with severe pain.

Subgrouping of low back pain (LBP) patients may be improved when pain drawings are combined with the painDETECT (PD-Q) questionnaire. We hypothesized that (1) different LBP subgroups determined by their pain radiation show different clinical patterns and (2) the occurrence of neuropathic symptoms depends on pain radiation. ⋯ Radicular patterns of pain drawings in LBP patients indicate severe pain conditions with the most neuropathic components, while axial LBP has the fewest. For the categorization of LBP, pain drawings help explain the underlying mechanism of pain, which might further improve mechanism-based treatment when used in clinical routines and research.

Randomized Controlled Trial Comparative Study
Comparison between bipolar pulsed radiofrequency and monopolar pulsed radiofrequency in chronic lumbosacral radicular pain: A randomized controlled trial.
Chronic lumbosacral radicular pain is a challenging medical problem with respect to therapeutic management. Many patients with lumbosacral radicular pain complain of persistent leg pain after transforaminal epidural steroid injection. Nowadays, pulsed radiofrequency (PRF) stimulation on the dorsal root ganglion (DRG) is widely used for controlling lumbosacral radicular pain. ⋯ The use of bipolar PRF on the DRG can be an effective and safe interventional technique for chronic refractory lumbosacral radiculopathy, particularly in patients whose pain are refractory to epidural steroid injection or monopolar PRF stimulation.
