Loss of vocal strength is a common side effect of Parkinson’s. Some people experience difficultywith articulation, as their speech becomes slurred. Muscle and motor issues such as difficulty controlling tongue movement, could cause this. Others experience a decrease in vocal volume that could be influenced by poor breath support.
Singing can help people with Parkinson’s by reinforcing vocal expression and sustaining breath support. People can build strength through singing. Intensive singing interventions have the potential to increase vocal loudness, respiratory muscle strength, and voice-related quality of life in people with Parkinson’s, a study suggests.
According to Elizabeth Stegemöller, an assistant professor of kinesiology at Iowa State University, singing uses the same muscle groups used for swallowing and breathing. Parkinson’s can have a major impact these functions. Singing Therapy for Parkinson’s focus on vocal exercises and songs to improve muscle activity and function. It also improves breath support and posture and increases muscle activity and control, all of which can help improve communications.
