Quality of life research investigates the function that physical therapy, occupational therapy, exercise or other interventions may play in the quality of life of persons with Parkinson's disease. Persons with Parkinson's disease may experience motor symptoms (tremors, rigidity, slowness of movement, postural instability and gait dysfunctions) as well as non-motor symptoms (neuropsychiatric symptoms, autonomic dysfunction, or other; see Parkinson's disease). Due to this diversity of symptoms, Parkinson's disease may impact upon an individual’s physical, social and mental well-being. For example, difficulties with movement can lead to difficulties with self-care, embarrassment, social-isolation, and depression.
