Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Two - four 6MWT performed according to ATS standards. Each walk however had specifically altered wording and coaching performed in random order to determine differences in outcomes. One walk was done in the standard ATS fashion. One was done coaching to walk as fast as the patient can walk. One was coached to walk at the patients normal walking pace. One was coached to walk at the patient's leisure walking pace.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Alternate 6MWT where subjects will be asked to walk as fast as they can, walk as normal as they can and walk leisurely as they can in 6 minutes compared to standard of care 6MWT which is walk as far as you can in 6 minutes.
