Randomized Controlled Trial Multicenter Study Observational Study
Cooled Radiofrequency Ablation Treatment of the Genicular Nerves in the Treatment of Osteoarthritic Knee Pain: 18 and 24-Month Results.
The primary objective of this observational, prospective, multicenter study was to evaluate the long-term outcomes, including pain, function, and perceived effect of treatment, in subjects undergoing cooled radiofrequency ablation (CRFA) who have pain due to osteoarthritis (OA) of the knee. ⋯ In this subset of subjects from a randomized controlled trial, CRFA provided sustained pain relief, improved function, and perceived positive effect through 24 months for subjects with OA knee pain with no safety concerns identified.

Chronic pain is commonly reported in individuals with spinal cord injuries (SCIs), with recent prevalence reported as high as 80%. Uncontrolled pain is known to decrease quality of life, attenuate mood, and impact sleep. Spinal cord stimulation (SCS) for the treatment of refractory pain was first used in the SCI population in 1972. To date there have been no randomized controlled trials examining the effect of SCS on neuropathic pain post-SCI. A literature review in 2009 identified 27 studies, the majority prior to 2000, that included at least 1 patient with SCI. Given the significant advancements in the field of SCS, this review examines the updated evidence of SCS for the treatment of neuropathic pain in individuals with SCI and provides guidance on future investigations. ⋯ The synthesized findings from primarily case studies support the safety of SCS in SCI with the suggestion of potential pain relief benefit; however, data from low-quality studies are insufficient for informing clinical practice. A well-designed, prospective clinical trial is proposed to further investigate this indication.

This study aimed to determine the optimal cutoff score of the 9-item short version of the CSI, the CSI-9, by comparing patients with central sensitivity syndrome (CSS) not only to healthy volunteers as with the original version, but also to patients with musculoskeletal (MSK) disorders. ⋯ The optimal CSI-9 cutoff score of 20 is beneficial to clinicians in the evaluation of central sensitization-related symptoms. The cutoff score helps to identify patients who need additional treatments, such as pain neuroscience education and cognitive behavioral therapy.

Clinical Trial
Goal identification before Spinal Cord Stimulation: a qualitative exploration in potential candidates.
Due to the difficulties encountered in the treatment process of patients with chronic pain, it is of utmost importance to involve patients themselves in their rehabilitation trajectory. Patient engagement can be obtained by motivating patients to select their own treatment goals. We hypothesize that applying goal setting, as a form of patient empowerment, in potential candidates for spinal cord stimulation (SCS) may further improve the outcome of SCS. As a first step in creating patient empowerment, patients' goals that they aim to achieve with SCS will be explored. ⋯ The interviews revealed a broad spectrum of individual patients' goals, highlighting the need of individually targeted rehabilitation trajectories in the field of neuromodulation. Goal identification could entail the first step towards individualized medicine in the SCS trajectory.

To further evaluate the efficacy and safety of computerized tomography-guided sphenopalatine ganglion-targeted pulsed radiofrequency treatment for patients with refractory episodic and chronic cluster headache (CH). ⋯ The computerized tomography-guided sphenopalatine ganglion-targeted pulsed radiofrequency procedure is an effective, safe, and repeatedly effective strategy for refractory CH. For patients who have not responded to conservative treatment, this minimally invasive intervention is a reliable alternative.
