Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals suffering from unilateral refractory neuropathic pain for over a year and whose analgesic treatment has been stable for at least one month.
✕Probably not a fit
Patients with a history of drug addiction, epilepsy, cranial trauma, or those who have previously undergone rTMS treatment may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study aims to evaluate the analgesic effectiveness of three different modes of repetitive Transcranial Magnetic Stimulation (rTMS) in patients suffering from chronic neuropathic pain. Participants will be randomly assigned to receive either classical rTMS, deeper rTMS, or a sham treatment after providing informed consent. They will record their pain intensity daily for one week before treatment and continue to do so during the seven weeks of neurostimulation sessions, followed by a two-week follow-up period. The study will assess the effectiveness of these interventions in managing refractory neuropathic pain.
Why it matters
Potential benefit: If successful, this study could provide a new non-invasive treatment option for patients with chronic neuropathic pain who do not respond to conventional therapies.
How similar studies have gone: Other studies have shown promising results with rTMS for pain management, indicating that this approach has potential based on previous findings.
