Chronic obstructive pulmonary disease (COPD) is an umbrella term used to describe progressive lung diseases such as emphysema, chronic bronchitis, and non-reversible asthma. People with COPD suffer with continued and increasing breathlessness. Too often, patients with COPD avoid exercise because of their shortness of breath. Without exercise and improving endurance, the shortness of breath will only worsen. Physical and occupational therapists can help COPD patients exercise in a safe and secure environment and can improve your strength, endurance, and help you conserve energy doing daily tasks. Therapists can also help reduce difficulty in breathing by providing helpful breathing exercise.
