Self-efficacy is one of the important factors affecting chronic diseases. In the current epidemiological context of low back pain (LBP), LBP self-efficacy has become a topic of great practical interest for researchers. However, no bibliometric analysis related to LBP self-efficacy has been performed to date. The purpose of this study was to conduct and explore the current state of research in LBP self-efficacy from 1980 to 2021, by using bibliometric analysis and scientific mapping. ⋯ The volume of literature on LBP self-efficacy has increased linearly over the past 41 years and will continue to increase. The field of study has become more refined. This bibliometric analysis provides valuable support for future directions and research trends in LBP self-efficacy.

We aim to provide an evidence-based overview of the use of psychedelics in chronic pain, specifically LSD and psilocybin. ⋯ Given the current epidemic use of opioids, and that patients are in desperate need of an alternative treatment, it is important that further research is conducted on the efficacy of psychedelics in chronic pain conditions.

We aim to assess the validity and reliability of the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM) and to add to its cross-cultural adaptation process by translating, culturally adapting, and validating the MPIIQM into European Portuguese language in the population of Portuguese musicians. ⋯ MPIIQM-Pt is the first validated questionnaire to evaluate pain among Portuguese musicians. It showed excellent psychometric properties, both in terms of internal consistency, test-retest reliability, factor analysis, and construct validity. Therefore, it is a valid and reliable tool suitable for both research and clinical practice purposes. MPIIQM-Pt will allow the development of more robust studies on pain among musicians and the improved assessment and monitoring of pain in this population, filling an important gap in this field of Pain Medicine.

Case Reports Randomized Controlled Trial
Dorsal Root Ganglion Stimulation for the Treatment of Joint Pain with Predominantly Nociceptive Characteristics: A Case Series.
Dorsal root ganglion stimulation (DRG-S) has recently emerged as a novel therapy in neuromodulation that demonstrated a higher rate of success than spinal cord stimulation (SCS) in a prospective, head-to-head randomized comparative trial to treat complex regional pain syndrome (CRPS) and causalgia. In contrast to SCS, DRG-S also shows promise in treating conditions that are not purely neuropathic such as axial low back pain, which has a prominent nociplastic pain component. It is not known to what extent the effectiveness of DRG-S for such indications is due to effective treatment of the neuropathic pain component versus the effects of DRG-S on mechanical pain. Although rarely studied, reporting outcomes of DRG-S to treat predominantly mechanical/nociceptive pain may help point toward expanding the utility of this therapy. Here, we present five cases of refractory mechanical pain treated with DRG-S. ⋯ This clinical report illustrates the potential utility DRG-S has in treating pain that clinically presents as predominantly refractory mechanical joint pain without a significant neuropathic component. The physiological reasons for our observations may be that DRG-S is able to directly influence the conduction of nociceptive signaling at the DRG and within the spinal cord. Further investigations are warranted to determine if DRG-S is a potential treatment option for chronic mechanical pain.
