Breathing Exercises to Improve Speech and Movement in Parkinson's

This pilot study is testing whether a single session of controlled breathing exercises—specifically, brief periods of breathing air with higher carbon dioxide levels—can help improve speech volume, cough strength, and body movement in people with Parkinson's disease. Researchers will compare two slightly different breathing approaches to see which works better and to understand how these treatments affect the body at a biological level.

Parkinson's disease often affects the muscles that control breathing, speech, and core body stability, and current medications don't adequately address these problems. This study is exploring whether breathing-based interventions might offer a new way to help with these difficult symptoms.
