Repetitive Transcranial Magnetic Stimulation Combined with Steroid Joint Injection for the Treatment of Chronic Spinal Pain: Protocol for a Pilot Randomized Controlled Trial
Chronic spinal pain (CSP) is one of the most common chronic pain conditions globally. Steroid joint injections (SJI) are a routine treatment option for patients with CLBP that is recalcitrant to other treatments. However, SJI has been shown to have limited long-term efficacy with patients often requiring another injection within months to adequately control pain. One option to prolong the analgesic effects of SJI is to use a type of noninvasive brain stimulation called repetitive transcranial magnetic stimulation (rTMS). Previous studies have shown rTMS may be capable of providing long-term pain relief in patients with chronic back pain. However, the literature on rTMS in patients with CSP is limited and no study has explored rTMS in patients receiving recurrent SJI for pain control. In this pilot randomized controlled trial study, we'll be investigating if combining rTMS with SJI in CSP individuals will enhance or prolong the analgesic effects of SJI alone. The investigators hypothesize that a combined rTMS and SJI intervention will be feasible, tolerable, and safe and will have larger and longer-lasting effects on CSP than a sham rTMS and SJI intervention.
