Correlation Between Handgrip Strength and Air Trapping in Patients with Stable Chronic Obstructive Pulmonary Disease

Correlation Between Handgrip Strength and Air Trapping in Patients with Stable Chronic Obstructive Pulmonary Disease

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.

Inclusion Criteria:

• Age 40 years or older
• Postbronchodilator FEV1/FVC <0.7
• >10 pack-year smoking history

Exclusion Criteria:

• COPD exacerbation within 3 months
• Inability to perform handgrip strength test or lung volume measurement
