Summary

This trial tests whether gentle air pulses delivered to the throat can help people who have trouble swallowing after a stroke. Half of the 80 participants will receive the active stimulation plus standard rehabilitation, while the other half gets a sham version. Researchers will measure changes in swallowing ability and brain activity using imaging and other tests to see if this approach can rewire the brain's swallowing network.

What this could mean

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

Active substance
Pharyngeal air-pulse sensory stimulation delivered via a device
What this could lead to
If effective, this could offer a new, non-invasive way to improve swallowing function and reduce choking risk in stroke survivors.
What could go wrong
This is a small, early-stage trial, and the sham control may produce similar effects. Results may not apply to all stroke patients.

Participants

About 80 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start
