The goal of this observational study is to investigate the relationship between handgrip strength and air trapping in patients with chronic obstructive pulmonary disease (COPD). The main question it aims to answer is: • Is handgrip strength correlated with air trapping in COPD patients? Participants will perform handgrip strength test and lung volume measurement.
This is a cross-sectional study in COPD patients. COPD patients aged 40 years or older were included. Handgrip strength test and lung volume measurement will be tested in each patient. Handgrip strength will be measured using a hand dynamometer. Lung volume will be assessed using a body plethysmograph.

Correlation between handgrip strength and air trapping in COPD patients
This correlation will be reported as correlation coefficient (R).
Time frame: At day 1 of the study
The best cutoff value of handgrip strength for predicting air trapping in COPD patients
The best cutoff value will be determined by the area under the Receiver Operator Characteristic curve (ROC).
