Can a simple massage or vibration ease dialysis cramps?
NCT ID NCT07777354
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial compares two drug-free therapies—leg massage and mechanical vibration—against standard care for reducing muscle cramps and improving comfort in people undergoing hemodialysis. About 160 patients on maintenance dialysis will be randomly assigned to receive either 20-minute leg massages, 10-minute vibration sessions, or usual care, three times a week for two weeks. Researchers will track cramp frequency and severity, sleep quality, and comfort scores to see which approach helps most.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Leg massage and mechanical vibration therapy
- What this could lead to
- If effective, these simple, drug-free therapies could offer personalized ways to reduce cramps and improve comfort for people on dialysis.
- What could go wrong
- This is a small, short-term trial, and results may not apply to all patients. Individual responses to massage or vibration can vary, and the study does not guarantee long-term benefits.
