Functional Test (6MWT)


The patient should know that this is a simple test requiring a walk on a flat, hard surface for six minutes. Speed, distance, and oxygenation levels will be measured. Results provide a good sense of functionality and oxygen requirements with exertion. Subsequent walk test results can help in the assessment of disease progression, as well as response to therapy.
