Exploring Balance Impairment and Determinants in Chronic Obstructive Pulmonary Disease: A Comparative Study with...

Area of Science:

• Pulmonary Medicine
• Neurology
• Geriatrics

Background:

• Balance impairment is a known issue in COPD, influenced by various factors, but determinants remain debated.
• This study aimed to compare balance and related variables between COPD patients and healthy controls.
• A secondary aim was to identify predictors of balance deficits in COPD.

Purpose of the Study:

• To compare balance and associated factors between COPD patients and matched healthy controls.
• To identify independent predictors of postural stability in individuals with COPD.
• To highlight the importance of addressing balance deficits for fall prevention in COPD management.

Main Methods:

• A comparative study involving 23 COPD patients and 23 age/comorbidity-matched healthy subjects.
• Assessment included balance tests (PST, LOST, CTSIB), pulmonary function, muscle strength (respiratory and peripheral), functional capacity (6MWT), and cognitive function.
• Statistical analyses correlated balance measures with clinical variables and identified independent predictors.

Main Results:

• COPD patients showed significant deficits in balance, pulmonary function, muscle strength, and functional capacity compared to controls.
• Postural Stability Test (PST) strongly correlated with maximal inspiratory pressure (MIP) and moderately with quadriceps strength and 6MWT distance.
• MIP, quadriceps strength, and 6MWT distance independently predicted PST performance (R² = 0.336).

Conclusions:

• Balance is demonstrably impaired in adults with COPD, even when matched for age and comorbidities.
• Inspiratory muscle strength, peripheral muscle strength, and functional capacity are significant determinants of balance in COPD.
• Targeted assessment and improvement of these factors are vital for fall prevention and managing COPD.
