Summary

This study tests whether an AI-powered app that guides chewing exercises can improve oral hygiene, chewing, and swallowing in people with schizophrenia. 100 participants from two hospitals will be randomly assigned to use the app before meals or receive standard care. The goal is to reduce risks like choking and pneumonia linked to poor chewing and swallowing.

What this could mean

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

Active substance
AI-assisted masticatory muscle training app
What this could lead to
If it works, this could offer a simple, drug-free way to improve chewing and swallowing in people with schizophrenia, reducing risks like choking or pneumonia.
What could go wrong
This is a small, early-stage trial with no blinding, so results may be influenced by placebo effects or participant motivation. The app requires a smartphone and daily commitment, which may limit who can benefit.
