Functional Test (6MWT)
A Six-Minute Walk Test (6MWT) is a practical, yet simple, low cost test that requires a 100 foot hallway (treadmills are not recommended) to measure the distance a patient can quickly walk on a flat, hard surface in a period of six minutes
The self-paced, unencouraged 6MWT assess submaximal levels of functional capacity, which better reflects most patients functional activities of daily living
- Indications: Pre-treatment and post-treatment comparisons, functional status, and predictor of morbidity and mortality
- Distance walked < 380 meters met with poorer one year survival in clinical trials
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.
