Is a patient self‐recorded 6 minute walk test equivalent to a formally recorded 6 minute walk test

Functional tests such as the 6-minute walk test (6MWT) are used in many areas of medicine to monitor disease progression and outcomes of treatment. They are particularly helpful in Orthopaedic surgery as the outcomes have been shown to be responsive to recovery over time. The 6MWT is typically performed in a controlled supervised environment which may limit its widespread use (Terwee et al., Rheumatology (Oxford), 2006, 45, 890-902). The primary aim is to investigate if a patient measured 6MWT is comparable to a 6MWT performed under formal testing conditions (Täger et al., Int. J. Cardiol. 2014, 176, 94-98).
