Chronic Obstructive Pulmonary Disorder (COPD) is a common preventable and treatable disease that is characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory response in the airways and the lung to noxious particles or gases. Hypoxia caused by restrictive airflow is one of the symptoms of COPD. Hypoxia can affect the inner ear and vestibular nuclei. Also, balance impairment can be caused by hypoxia. Previous studies show that balance affected negatively in COPD patients. The aim of this study is to investigate of vestibular system influence in individuals with COPD. A total of 10 COPD patients and 10 healthy adults will include the study. This research is planned to be carried out as a cross-sectional/descriptive research. It's planned as a pilot study. Respiratory functions (respiratory function test), vestibular functions (head shake test, head trust test, unterberger test) and postural stability (sensory organization test) of participants will be assessed.Comparisons between study and control groups will be made with independent samples t-test for parametric values and Mann Whitney U for non-parametric values.
