Brief summary
The goal of this observational study is to investigate the correlation between handgrip strength and small airway disease among patients with chronic obstructive pulmonary disease (COPD). The main question it aims to answer is: • Is handgrip strength correlated with small airway disease in COPD patients? Participants will perform handgrip strength test and impulse oscillometry (IOS).
Detailed description
This is a cross-sectional study in COPD patients. COPD patients aged 40 years or older were included. Handgrip strength test and impulse oscillometry will be tested in each patient. Handgrip strength will be measured using a hand dynamometer. Small airway disease will be assessed using IOS.
Interventions
Handgrip strength will be measured by 3 efforts.

Eligibility
Inclusion criteria
* COPD patients aged 40 years or older * Confirmed diagnosis by spirometry (post-bronchodilator FEV1/FVC \<0.7) * Smoking history 10 pack-years or more

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between handgrip strength and small airway disease in COPD patients | At day 1 of the study | This correlation will be reported as correlation coefficient (R). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The best cutoff value of handgrip strength for predicting small airway disease in COPD patients | At day1 of the study | The best cutoff value will be determined by the area under the Receiver Operator Characteristic curve (ROC). |
