Can vibrating airways and chest walls improve sleep in COPD patients?

This study looked at two types of vibrating devices—one that sends vibrations into the airways and one that vibrates the chest wall—to see if they could help people with COPD breathe better and sleep more soundly during a sudden worsening of their condition. 33 adults with severe COPD took part. The researchers measured breathing, sleep quality, and physical function before and after using the devices.
