The lumbar medial branch nerve has historically been a focus for ablative techniques in the treatment of chronic low back pain (CLBP) of facetogenic origin. Recent developments in the field of neuromodulation have been employed to target these nerves for analgesia and/or functional restoration in broader populations of CLBP patients. The objective of this article was to provide an introductory review of procedural techniques and devices employed for peripheral nerve stimulation (PNS) of the lumbar medial branch of the dorsal ramus for the treatment of CLBP. ⋯ Our review of the current literature regarding techniques for neuromodulation of the medial branch of the dorsal ramus revealed two dominant methods: a temporarily implanted percutaneous coiled-lead approach and a permanently implanted system. The two techniques share some similarities, such as targeting the medial branch of the dorsal ramus, and also have some differences, such as indwelling time, stimulation parameters, duration of treatment, image guidance, and degrees of invasiveness, but they are both demonstrating promising results in clinical trials.

Back pain "red flags": which are most predictive of serious pathology in the Emergency Department?
To determine the frequency of red flag signs and symptoms in patients presenting with back pain to the Emergency Department (ED) and association with serious pathologies and investigations performed. ⋯ The majority of this study cohort had back pain of benign cause. Some red flags were associated with greater risk of serious pathology, others were not. Further evidence regarding red flags and their association with serious pathology is required, to better inform clinical guidelines.

The Mainz Pain Staging System (MPSS), which has been validated primarily in middle-aged and chronic low back pain patients, is designed to predict prognosis and control the use of resources at baseline. In multi-morbid and functionally impaired patients (geriatric patients) with multiple causes of pain, it is unclear whether this instrument can be implemented at all and whether it permits statements to be made on the severity of pain chronification. ⋯ MPSS can be used in multi-morbid and functionally impaired elderly patients undergoing inpatient treatment. Chronification features are more pronounced at higher stages than at lower levels. Only one category of the MPSS cannot be collected by self-assessment. The possibilities of prognosis estimation and resource control using the MPSS should be further investigated for these patients.

Comparative StudyLow Back Pain in School-Aged Martial Arts Athletes in Japan: A Comparison among Judo, Kendo, and Karate.
Martial arts, such as judo, kendo, and karate, are popular worldwide, not only among adults but also among children and adolescents. Although low back pain (LBP) is considered to be a common problem in these sports, it has been scarcely studied, especially in young athletes. The purpose of this study was to elucidate the point prevalence of and factors related to LBP among school-aged athletes in judo, kendo, and karate. ⋯ Older age was significantly associated with LBP in judo (adjusted OR, 2.12 [95% CI, 1.24-3.61]), kendo (1.77 [1.27-2.47]), and karate (2.22 [1.14-4.33]). Lower extremity pain was significantly associated with LBP in judo (6.56 [1.57-27.34]) and kendo (21.66 [6.96-67.41]). Coaches should understand the characteristics of LBP in each martial art to develop strategies to prevent LBP among school-aged martial arts athletes.

Artificial intelligence algorithms can now identify hidden data patterns within the scientific literature. In 2019, these algorithms identified a thermoelectric material within the pre-2009 chemistry literature; years before its discovery in 2012. This approach inspired us to apply this algorithm to the back pain literature as the cause of back pain remains unknown in 90% of cases. ⋯ Artificial intelligence algorithms can successfully extract complex concepts from back pain literature. While use of AI algorithms to discover potentially unknown word associations requires future validation, our results provide investigators with a novel tool to generate new hypotheses regarding the origins of LBP and other spine related topics. To encourage use of these tools, we have created a free web-based app for investigator-driven queries.
