About this study
Official title: Correlation of Diaphragmatic Thickness With Pulmonary Function in Parkinson's Disease
Ultrasound can give important information about the morphology of the diaphragm and the amount of contraction. Our aim, with the prediction that a restrictive pathology will occur in the pulmonary function with the addition of camptocormia in Parkinson's patients; to compare respiratory functions in Parkinson's patients with and without camptocormia, to investigate the correlation between ultrasonographically measured diaphragmatic thickness and pulmonary function test values.
Read the detailed description
Respiratory complications are one of the most common causes of death in Parkinson's patients. In Parkinson's disease, abnormal flexion of the thoracolumbar spine of 45° or more, which is called camptocormia, increases during walking or standing and disappears completely in the supine position. The prevalence of camptocormia among Parkinson's patients is about 7%. Camptocormia in Parkinson's disease is associated with significant disease disability, higher daily dopaminergic drug dosage, and cognitive impairment. Parkinson's patients with camptocormia often complain of shortness of breath, attributed to reduced pulmonary capacity due to limited chest expansion. Diaphragmatic dyskinesia in Parkinson's patients may also lead to a restrictive deterioration in respiratory functions.
Diaphragmatic thickness indicates diaphragmatic contraction and is correlated with PFT. Our aim; It is a comparison of respiratory functions in Parkinson's patients with and without camptocormia.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pulmonary function test
When the patient is in the suIt will be evaluated by conventional spirometric measurements. Pulmonary function tests will be applied to all individuals in a sitting position with the "Vmax Encore PFT system, Carefusion, CA USA" brand test device. In each measurement, the maneuvers will be repeated at least 3 times and the best values will be recorded. Forced vital capacity (FVC), expire in the first second of forced expiration (FEV1), and the ratio of FEV1 to FVC (FEV1/FVC) will be recorded.pine position, by placing a transducer on the chest wall at the level of the right 9th intercostal space, diaphragmatic movement will be monitored during inspiration, and diaphragmatic thickness will be measured at the end of expiration and inspiration. Thrombus location was evaluated proximal and/or distally by performing Doppler ultrasound
Measured: 1 hour
Ultrasonography
When the patient is in the supine position, by placing a transducer on the chest wall at the level of the right 9th intercostal space, diaphragmatic movement will be monitored during inspiration, and diaphragmatic thickness will be measured at the end of expiration and inspiration. Thrombus location was evaluated proximal and/or distally by performing Doppler ultrasound
Measured: 1 hour
Secondary outcomes (1)
Camptocormia measurement
Postural deviations of the spine, knees and hips will be recorded through photographs taken from the side and back in the standing position. The individual's flexion of more than 45° from the thoracolumbar spine will be recorded as the presence of camptocormia. Waist, right and left knee circumference measurements also recorded
Measured: 1 hour

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2024; AzTrials last refreshed its copy on 6 Nov 2026.
