Does Vestibular System Effected in Chronic Obstructive Pulmonary Disease Patients

Study Overview
=================
Brief Summary
-----------------
. The main question is whether the vestibular system is affected by COPD. If there is an influence, the second question is what is the relationship between balance and vestibular interaction in COPD patients. A total of 10 COPD patients and 10 healthy adults will include the study. Respiratory functions, vestibular functions and postural stability of participants will be assessed. This research is planned to be carried out as a cross-sectional/descriptive research. It's planned as a pilot study. 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.

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Vestibular Assessment 1 | Head Shake Test:The head shake test is performed by shaking the head of the patient. The head is rotated at a comfortable range at a frequency of about 2 to 3 Hertz for 10- to 15 seconds. After shaking, the head remains in the center and the eyes of the patient are observed for nystagmus. The head shake test is used to look for signs of dynamic imbalance of vestibular function by evaluating the post-shaking nystagmus. | After the individuals permission, in first 4 minutes | 
| Balance Assessment | Subjects stands on dual force plates and and their anterior posterior sway recorded in different test conditions. Eyes open- stable support Eyes closed- stable support Eyes open- stable support Eyes open-Foam surface Eyes closed-Foam surface Eyes open-Foam surface | After the individuals permission, in first 20 minutes | 
| Respiratory Assessment - Spirometry - Forced expiratory volume in 1 s (FEV1) | *We will supply the information of test results from patients' folders.* Forced expiratory volume in 1 s (FEV1) Spirometry is the term given to the basic lung function -volume, time and flow- tests that measure the air that is expired and inspired. Spirometry is objective and noninvasive. Before performing the forced expiration, tidal (normal) breaths can be taken first, then a deep breath taken in while still using the mouthpiece, followed by a further quick, full inspiration. | After the individuals permission, in first 22 minutes | 
| Respiratory Assessment - Spirometry - Forced vital capacity (FVC) | *We will supply the information of test results from patients' folders.* FVC, the maximum amount of air that can be exhaled when blowing out as fast as possible Spirometry is the term given to the basic lung function -volume, time and flow- tests that measure the air that is expired and inspired. Spirometry is objective and noninvasive. Before performing the forced expiration, tidal (normal) breaths can be taken first, then a deep breath taken in while still using the mouthpiece, followed by a further quick, full inspiration. | After the individuals permission, in first 22 minutes | 
| Respiratory Assessment - Spirometry - Vital capacity (VC) | *We will supply the information of test results from patients' folders.* Vital capacity (VC), the maximum amount of air that can be exhaled when blowing out as fast as possible Spirometry is the term given to the basic lung function -volume, time and flow- tests that measure the air that is expired and inspired. Spirometry is objective and noninvasive.

| Vestibular Assessment 2 | Head Trust Test: A brief, high-acceleration head thrust can test vestibular function of all semicircular canals. Depending on the semicircular canal tested, the head is rotated in a different direction. A corrective catch-up saccade is made in case of vestibular hypofunction. | After the individuals permission, in first 8 minutes | 
| Vestibular Assessment 3 | Unterberger test: Subjects will close their eyes and begin stepping in place for 60 seconds with shoulder at 90 degrees flexion, arms extended forward. The distance will be measured from the start point to end point. | After the individuals permission, in first 10 minutes |
