Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 to 80 with chronic peripheral neuropathy and a pain score of 4 or higher on a numerical rating scale.

Probably not a fit

Patients with neurological disorders, psychiatric illnesses, or contraindications to TMS will not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of three different repetitive transcranial magnetic stimulation (rTMS) protocols in treating patients with chronic peripheral neuropathic pain. A total of 36 patients aged 18 to 80 will be randomly assigned to receive either classical high-frequency rTMS (CHF-rTMS), spaced high-frequency rTMS (SHF-rTMS), or accelerated intermittent theta burst stimulation (ACC-iTBS). The study aims to compare the analgesic efficacy of these protocols to determine the most effective treatment approach for neuropathic pain. Participants will be recruited from the Clinical Neurophysiology department at Henri Mondor University Hospital in France.

Why it matters

Potential benefit: If successful, this study could provide a more effective non-drug treatment option for patients suffering from neuropathic pain.

How similar studies have gone: Previous studies have shown that rTMS can be effective for neuropathic pain, but this specific comparison of protocols is novel.
