Large changes needed to indicate true improvement limit 6MWT utility for monitoring cardiac rehab patients; challenges reliability for serial assessments due to learning effects.
Is the six-minute walk test a reliable exercise test for patients referred to cardiac rehabilitation when up to three tests are performed?
The six-minute walk test may lack sufficient absolute reliability to evaluate exercise tolerance in cardiac rehabilitation patients due to a learning effect across repeated tests.
