Electrical stimulation for chronic upper limb pain relief
Official title: Treatment of Upper Limb Chronic Neuropathic Pain by Electrical Stimulation of the Brachial Plexus Nerve Roots
Run by Centre Hospitalier Universitaire de Nice · NCT05817786 · Data updated 2026-11-12
This study is testing if electrical stimulation of certain nerves can help people with chronic pain in their arms feel better when other treatments haven’t worked.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 80 with moderate to severe unilateral chronic neuropathic pain in the upper limb that has persisted for over 12 months and is refractory to first and second line treatments.
✕Probably not a fit
Patients with brachial plexus avulsion or post-zoster neuropathy may not benefit from this treatment.

What this trial studies
This clinical trial investigates the effectiveness of electrical stimulation of the brachial plexus nerve roots in alleviating moderate to severe chronic neuropathic pain in the upper limb. The study employs a controlled approach to assess pain relief, quality of life improvements, and safety outcomes in patients who have not responded to conventional treatments. Participants will receive either active stimulation or sham stimulation, with the implantation technique guided by ultrasound for precision. The trial aims to provide robust evidence on the efficacy of this novel neuromodulation technique.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce chronic pain and improve the quality of life for patients suffering from neuropathic pain in the upper limb.
How similar studies have gone: While peripheral nerve stimulation has shown promising results in small series, this specific approach for brachial plexus stimulation has not been extensively evaluated in controlled conditions.
