Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with CIPN symptoms for at least three months, moderate pain (≥4/10), at least three months since their last neurotoxic chemotherapy dose, able to attend daily treatments, and able to give informed consent.

Probably not a fit

People who are pregnant or nursing, have implanted electronic medical devices, recent ischemic heart disease, a history of seizures, or who expect imminent further neurotoxic chemotherapy may not be eligible or likely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with persistent CIPN receive up to ten daily one-hour sessions of Scrambler Therapy delivered through adhesive electrodes placed near areas of pain, tingling, or numbness. Some participants may be assigned to active Scrambler Therapy while others receive a sham or no-intervention control to compare effects. The study measures changes in neuropathic pain intensity, related symptoms, function, and quality of life. Treatment may stop early if participants no longer report neuropathic pain.

Why it matters

Potential benefit: If successful, Scrambler Therapy could reduce CIPN pain and numbness and improve daily function without adding systemic medications.

How similar studies have gone: Small prior studies and case series have reported positive effects of Scrambler Therapy for neuropathic pain and the device has FDA clearance, but larger randomized trials are limited.
