What is the typical expected improvement in 6-minute walking distance to consider a pulmonary rehab program effective?

1. 5-10%

2. 10-15%

3. 10-20%

4. 20-25%

The correct answer is: 10-20%

The typical expected improvement in the 6-minute walking distance that would indicate an effective pulmonary rehabilitation program is generally considered to be in the range of 10-20%. This range is established based on clinical studies assessing outcomes of various rehabilitation interventions aimed at improving the functional capacity and exercise tolerance of patients with chronic respiratory conditions. An improvement of this magnitude reflects significant physiological and psychological benefits, enhancing not only the physical endurance of the patients but also their overall quality of life. Improvements of less than 10% may not be considered clinically meaningful, while increases above 20% may be indicative of exceptional individual responses rather than typical outcomes seen in most patients participating in such programs.
