Summary

This study tests whether stimulating the tongue with a non-invasive device can improve arm movement and brain plasticity in people who had a stroke at least six months ago. Participants will do a 4-week strength training program for their affected arm, combined with either real or sham tongue stimulation. Researchers will measure changes in arm function and brain activity to see if the tongue stimulation adds benefit.

What this could mean

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

Active substance: cranial nerve non-invasive neuromodulation (CN-NINM) via tongue stimulation
What this could lead to: If it works, this could offer a new, non-invasive way to boost arm recovery after stroke by combining tongue stimulation with strength training.
What could go wrong: This is an early-stage trial with only 74 participants, and the tongue stimulation is experimental for stroke. It may not improve function more than training alone.
