Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

This observational, cross sectional 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. In this study is to evaluate the thickness of abdominal accessory respiratory muscles (rectus abdominis, transversus abdominis, and oblique muscles) using ultrasonography in patients with Parkinson's disease. Additionally, the relationship between disease severity and expiratory respiratory muscle strength will be examined. Respiratory muscle strength will be assessed using maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) measurements. Disease severity will be evaluated using standardized clinical scales.

These findings will underscore the importance of evaluating respiratory muscles in Parkinson's disease and may contribute to the development of rehabilitation programs targeting respiratory muscles in the later stages of the disease.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Parkinson Disease (PD)

Abdominal Accesory Respiratory Muscles (rectus abdominis, transversus abdominis, and oblique muscles) and MIP(maximum inspiratory pressure) MEP(maximum expiratory pressure) values of the group with Parkinson's diagnosis and Hoehn Yahr Stage 1-2-3 will be measured, a 6-Minute Walk Test will be performed and the results will be noted.

No interventions assigned to this group

Control Group

Abdominal Accessory Respiratory Muscles (rectus abdominis, transversus abdominis, and oblique muscles) and MIP (maximum inspiratory muscles) MEP(maximum expiratory muscles) values of age and gender matched healthy values of age and gender matched healthy volunteers without any diagnosis of neuromuscular disease or chest diseases will be measured and the results will be noted.

No interventions assigned to this group
