Summary

This study tests whether a device that gently stimulates a nerve in the ear (taVNS) can improve arm and hand function in stroke survivors. Thirty adults who had a stroke within the last five years will receive either real taVNS or a sham (fake) stimulation combined with physical therapy for two weeks. Researchers will measure changes in motor skills and daily activities to see if the real stimulation offers extra benefits.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: trans-auricular vagus nerve stimulation (taVNS) device
What this could lead to: If it works, this could offer a non-invasive way to boost arm and hand recovery after a stroke, helping people regain daily function.
What could go wrong: This is a small, early-phase trial with only 30 people over two weeks. Results may not apply to all stroke survivors, and the sham group might show similar improvement.
