Effects of Active Versus Passive Music Therapy on Functional Ability and Psychophysiological Responses to Goal-Directed Exercise in People With Parkinson's Disease

Using a crossover counterbalanced approach, participants with idiopathic PD (n=28) will be recruited to complete 3 separate experimental visits each with a differing condition: 1) No music (control; CON), 2) PMT, 3) AMT. For each condition, participants will complete a battery of functional testing (sit-to-stand test; STS) and goal-based exercise (6-minute walk test; 6MWT) separated by 20-minutes of rest. Functional ability will be determined via biomechanical parameters (i.e. peak force, braking force, rate of force development) during the 5-time STS test. Exercise capacity (i.e. distance, average walking velocity) will be determined for goal-based exercise during the 6MWT. During each test, a medical grade smartwatch will record psychophysiological (i.e. heart rate, metabolic equivalents, electrodermal activity) responses. Furthermore, psychometric testing for motivation, enjoyment, psychological arousal, fatigue, and rating of perceived exertion will be conducted after each test attempt.
