Could a simple vibrating pad ease chemo nerve damage?
NCT ID NCT04959929
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This study tests whether a wearable device that vibrates the legs can help relieve persistent nerve pain and numbness caused by chemotherapy. The device, called Myovolt, is worn on the legs for about 30 minutes twice a day. Researchers are looking at how practical and acceptable the device is for patients, and whether it improves symptoms and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a wearable device that delivers focal vibration therapy to the legs
- What this could lead to
- If it works, this could offer a drug-free way to manage chemotherapy-induced nerve pain and improve quality of life for cancer survivors.
- What could go wrong
- This is a very early, small feasibility study with only 13 participants, so results may not apply broadly. The device may not provide meaningful relief for everyone.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18 years or older * Cancer patients with current symptoms of chemotherapy induced peripheral neuropathy affecting the feet, persisting for at least 3 months after completion of chemotherapy, and not substantially improving in recent weeks. The CIPN must be painful, or severe enough to interfere with function, activities, or participation (generally NCI-CTCAE Grade II) * Clinically stable to participate in study assessments and the intervention (at a minimum, able to stand independently from a chair and walk household distances without help from another person) * Able to read and speak English, give a voluntary written consent * Sufficient cognition to consent, confirmed by recall of key study points * Use of pain medications (opioids, anti-convulsants, and antidepressants) must be stable in the two weeks prior to study enrollment, and the participant must agree to avoid significant changes in pain medication regimen during the period of active study participation, and to notify the study team if medications change Exclusion Criteria: * Neuropathy (known or suspected) of any etiology other than chemotherapy or diabetes (for example, due to alcohol, vitamin deficiency, autoimmune disorder, CMT, idiopathic * Unsafe/unable to self-apply the focal vibration intervention for any reason (for example, insufficient hand dexterity or cognitive executive function * Recent or fluctuating musculoskeletal injury or lesion that would impact physical performance * Lower limb deficiency/amputations * Pregnant, or planning to get pregnant in the next 6 months. Pre-menopausal females who enroll agree to notify the study team as soon as possible should they become pregnant
