Sponsor's own description
Parkinson's disease is a neurodegenerative disorder characterized by both motor and non-motor symptoms. The involvement of respiratory muscles can lead to impairments in respiratory function in these patients. In this study is to evaluate the thickness of abdominal accessory respiratory muscles using ultrasonography in patients with Parkinson's disease. Additionally, the relationship between disease severity and expiratory respiratory muscle strength will be examined. The study will include Parkinson's patients at different stages of the disease, with respiratory muscle thickness measured via ultrasonography. The collected data will then be compared with disease severity and expiratory muscle strength.
