NCT ID NCT07416708
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a device that gently stimulates a nerve in the ear to see if it can improve thinking, sleep, and inflammation in older adults with frailty. Eighty people over 60 received either the active stimulation or a sham version, along with standard physical therapy, for two weeks. Researchers measured changes in cognitive tests, sleep quality, and blood markers of inflammation.

Active substance
Transcutaneous auricular vagus nerve stimulation (taVNS) device
What this could lead to
If it works, this could offer a simple, non-invasive way to help older adults think more clearly and sleep better.
What could go wrong
This was a small, short-term study (80 people, 2 weeks) with no phase. The results may not apply to everyone, and the sham group might also improve from other therapies.
