Summary

This study tested whether a breathing exercise using an Ambu-bag (air stacking) can improve lung function and trunk control in people who had a stroke. Twenty stroke survivors did either the air stacking breathing exercise or standard diaphragmatic breathing, three times a week for four weeks. Researchers measured changes in lung capacity, chest expansion, and trunk control before and after the program.

What this could mean

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

Active substance: air stacking-assisted diaphragmatic breathing exercise using an Ambu-bag
What this could lead to: If it works, this breathing technique could become a simple, low-cost way to help stroke survivors breathe better and improve their trunk control.
What could go wrong: This is a very small, early-stage study with only 20 participants. Results may not apply to all stroke patients, and the improvement might be modest.
