Balance impairment in patients with COPD

Area of Science:

• Pulmonary Medicine
• Geriatrics
• Neurology

Background:

• Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation and respiratory distress.
• COPD shares physiopathological features with risk factors for falls identified in older individuals.
• Understanding balance deficits and fall risk in COPD is crucial for patient management.

Purpose of the Study:

• To compare and quantify functional balance between COPD patients and healthy subjects.
• To investigate the risk of falls in acute stages of COPD.
• To identify risk factors associated with falls in COPD patients.

Main Methods:

• A study involving 46 moderate-severe COPD patients (29 stable, 17 acute exacerbation) and 17 healthy controls.
• Functional balance assessed using Berg Balance Scale (BBS), Single Leg Stance (SLS), and Timed Up and Go (TUG) tests.
• Correlation analysis between balance scores and risk factors like anxiety and depression.

Main Results:

• COPD patients exhibited significantly worse balance scores compared to controls (BBS, TUG, SLS).
• Patients experiencing acute exacerbations of COPD (AECOPD) showed the most severe balance impairments.
• Anxiety and depression levels were significantly associated with poorer balance test outcomes in COPD patients.

Conclusions:

• Moderate-to-severe COPD patients, particularly those with acute exacerbations, face a high risk of falls.
• Balance deficits in COPD are linked to disease severity and psychological factors.
• Targeting anxiety and depression may be important in mitigating fall risk in COPD.
