This cross-sectional study aims to investigate to the impairments in body functions and structures, activities and participation restrictions according to the International Classification of Functioning, Disability and Health (ICF) framework in Chronic Obstructive Pulmonary Diseases (COPD) patients.
To investigate the impairments in body functions and structures, activities and participation restrictions according to the International Classification of Functioning, Disability and Health (ICF) framework in patients with COPD, fifty patients with COPD will be included. The Modified Medical Research Council Dyspnea (MMRC) scale and Six-Minute Walking Test (6MWT) will be used for evaluating the how dyspnea limits the patients' daily activities and functional capacity, respectively. Isometric muscle strength will be measured with a handheld dynamometer of quadriceps femoris. Fear of falling will be assessed with Activities-Specific Balance Confidence (ABC) scale. The level of dyspnea during daily activities will be assessed with London Chest Activity of Daily Living (LCADL) scale. The global impacts of COPD symptoms on overall health status will be evaluated by The COPD Assessment Test (CAT). Pulmonary function data will be retrieved from the last 1-month clinical records of the COPD patients. Statistical analysis will be performed using the Statistical Package for Social Sciences (SPSS) version 21.0. Descriptive statistics of continuous variables will be presented with mean, standard deviation (SD), confidence interval (CI) values, and descriptive statistics of categorical variables will be presented with frequency and percentage values. The conformity of the data to the normal distribution will be evaluated with the "Shapiro Wilk Test". According to the results of the analysis, "Pearson correlation test" or "Spearman correlation test" will be used to determine the relationship between dependent variables. The significance level will be set as p\<0.05.

Activities-Specific Balance Confidence scale
Activities-Specific Balance Confidence (ABC) scale will be used for evaluating the confidence in maintaining the balance in activities daily living. It provides information on the level of concern about falls during16 community-based and home-based activities. Scale scores between 0 (unsafe) to 100 (completely safe) and the total score (0-1600) is divided by 16 to obtain an individual's ABC score, with higher scores indicating greater balance confidence. In patients with COPD, the ABC scale has demonstrated construct validity as well as criterion validity for falls. In addition, the participants will be also questioned concerning the occurrence of falls and the risk of falling during the activity in each item of the ABC scale.

London Chest Activity of Daily Living scale
London Chest Activity of Daily Living (LCADL) scale is used for assessing the level of dyspnea during daily activities. It is a 15-item scale comprised 4 domains: self-care (4 items), domestic (6 items), physical (2 items), and leisure (3 items). Each item scored between 0 (I wouldn't do it anyway) to 5 (I need help in doing this or someone to do it for me) and the total score ranges from 0 to 75, with higher scores indicating a more significant limitation in daily activities. The LCADL scale is a reliable, valid, and responsive instrument to assess limitations in performing daily activities in COPD patients. asked to rate each item in terms of risk of falling using a five-point scale, where 1=very low, 2=low, 3=moderate, 4=high, and 5=very high.
Time frame: Baseline
The COPD Assessment Test
The COPD Assessment Test (CAT) will be used for evaluating the global impacts of COPD symptoms on overall health status. Each item scores between 0 to 5 and the total score ranges from 0 to 40, with higher scores indicating the more severe impact of COPD on health status.

The strength of quadriceps femoris
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
The strength of quadriceps femoris of both sides will be measured with a hand-held dynamometer (kg.N-1) ''Nicholas Manual Muscle Tester" (model 01160, The Lafayette Instrument Company, Lafayette, Indiana). Each limb will assessed 3 times, with a recovery period of 30 seconds and the mean value will be calculated.
Time frame: Baseline
The Modified Medical Research Council Dyspnea scale
The Modified Medical Research Council Dyspnea (mMRC) scale will be used to determine how dyspnea limits the patients' daily activities performance. Itis a five-level rating scale consisting of just five items containing statements about the impact of dyspnea on the patients' daily activities performance and leading to a grade from 1 to 5. Higher scores indicate a greater impact of dyspnea on the patients' daily activities performance.
Time frame: Baseline
Six-Minute Walking Test (6MWT)
Six-Minute Walking Test (6MWT) is a reliable and valid test for evaluating functional capacity. Two 6MWTs will be performed according to the guidelines of the American Thoracic Society. The distance in meters covered over the 6 minutes of the test (6MWD) will be recorded.
