Effects of music-based voice intervention protocol on vocal amplitude, pitch range, respiratory rate, and quality of life of people with Parkinson’s Disease

Parkinson’s Disease (PD) is a chronic neurodegenerative disease in which the symptoms worsen over time. These symptoms are characterized by motor and non-motor problems marked by tremor at rest, muscular rigidity, and slow movements. In addition, people with Parkinson’s Disease (PwP) are prone to de...
