Could a gentle brain zap restore sensation after chemotherapy?
NCT ID NCT07673614
First seen Jun 29, 2026 · Last updated Jul 17, 2026 · Updated 4 times
Summary
This trial tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can help cancer survivors with chemotherapy-induced peripheral neuropathy (CIPN). CIPN causes numbness, tingling, pain, and movement problems. The study compares active tDCS to a sham (fake) procedure in 50 cancer survivors who are no longer on active treatment. Researchers measure changes in vibration and cold detection, balance, and walking ability right after stimulation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcranial direct current stimulation (tDCS)
- What this could lead to
- If effective, tDCS could offer a non-drug way to ease nerve pain and improve movement in cancer survivors with lasting chemotherapy side effects.
- What could go wrong
- This is a small, early-stage trial with 50 people. The effects are temporary, and it may not work for everyone or lead to a lasting treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 18 to 85 years of age * Diagnosis of cancer, stages I-IV * Cancer survivor (not currently receiving chemotherapy, radiation, or immunotherapy) * Presence of CIPN defined as new, length-dependent numbness, tingling, and/or pain that developed with neurotoxic chemotherapy * CIPN20 score ≥ 20 * Able to walk unassisted * Proficient in English Exclusion Criteria: * Known brain metastases * Known neurological conditions aside from chemotherapy-induced peripheral neuropathy (CIPN) * History of brain or spinal surgery * Neuropathy other than CIPN * Significant hearing or vision deficits * Vestibulopathy * Currently receiving chemotherapy, radiation therapy, or immunotherapy * Contraindications to transcranial direct current stimulation (tDCS), including recent seizures * Presence of metallic objects in the head * Presence of specific implanted medical devices (e.g., deep brain stimulator, cochlear implant, vagus nerve stimulator, spinal cord stimulator, pacemakers, and intracardiac devices) * Active scalp dermatological conditions
