Deep Brain Stimulation (DBS) and Motor Cortex stimulation (MCS) are invasive interventions in order to treat various neuropathic pain syndromes such as Central Post-Stroke Pain. While each treatment has varying degree of success, comparative analysis has not yet been performed, and the success rates of these techniques using validated, objective pain scores have not been synthesised. ⋯ The use of neurosurgical interventions such as DBS and MCS are last-resort treatments for Central Post-Stroke Pain, with limited studies exploring and comparing these two techniques. While our study shows that MCS might be a slightly better treatment option, further research would need to be done to determine the appropriate surgical intervention in the treatment of Central Post-Stroke Pain.

Randomized Controlled Trial Multicenter Study Comparative Study
Trigger Point Injections for Myofascial Pain in Terminal Cancer: A Randomized Trial.
The aim of this study was to evaluate the efficacy and safety of a single trigger point injection (TPI) of a local anesthetic for the treatment of myofascial pain syndrome (MPS) in patients with incurable cancer. ⋯ A single TPI of a local anesthetic is safe and efficacious in inducing an immediate reduction in MPS-related pain in patients with incurable cancer. Clinical trials registration number: This study was registered with the Japan Registry of Clinical Trials (approval number: jRCTs051210132) on December 16, 2021. https://jrct.niph.go.jp/en-latest-detail/jRCTs051210132.Approval of the research protocol by a Certified Review Board: The present study was approved by the Wakayama Medical University (reference number: CRB5180004. Registered 26 May 2021).

Radiofrequency ablation is a common non-opioid treatment to manage chronic knee pain. The inferior medial genicular nerve is conventionally targeted. It has been suggested that the infrapatellar branch (saphenous nerve) should also be targeted. There is controversy regarding the contribution of the infrapatellar branch to the innervation of the knee joint capsule. ⋯ Proposed protocol targeting the infrapatellar branch is likely to capture the inferior medial genicular consistently regardless of the anatomical variation of the infrapatellar branch.
