Six Minute Walk Test There are many tools for assessing functional exercise capacity, most of which provide good information about the body system. The most popular clinical exercise tests are stair climbing, a 6MWT, a shuttle walking test, exercise-induced asthma detection, a cardiac stress test, and a cardiopulmonary exercise test) (ATS, 2002). In the past, functional exercise capacity was assessed by asking patients “How many flights of stairs can you climb or how many blocks can you walk?”; but this assessment was a subjective measurement. Furthermore, the first objective tool dates back to the 1960s and was the 12-minute walk test; however, it was so exhausting for the patients. Consequently, it has been found that a 6-minute walk test (6MWT) can be used as an objective measurement tool of functional exercise capacity in patients with mild to moderate respiratory and cardiac disease (ATS, 2002). Many studies have concluded that the 6MWT is an inexpensive test and “…is easy to administer, better tolerated, and better reflects activities of daily living than other walking tests” (ATS, 2002). Therefore, this essay will describe the 6MWT and comment on the administration, application, reliability, and validity based on literature reviews. Chang (2006) stated that the 6MWT measures the distance patients can travel on a flat surface as fast as possible with necessary stops. by patients within 6 minutes. Additionally, 6 MWT may reflect the level of exercise needed for daily activities. Morales-Blanhir, Vidal, Romero, Castro, Villegas, Zamboni (2010) demonstrated that the main indications of the 6MWT are to measure the response to the intervention given to patients and it can also be used to measure the functional status of patients. as predictive... half of the article... patients with left ventricular dysfunction were involved in the study. The 6MWT was one of the assessment tools, and the authors performed the 6MWT at baseline, then repeated it after 242 days. The authors compared patients with high 6MWD with patients with lower 6MWD. Consequently, they concluded that patients with a lower 6MWD were significantly more likely to die (Morales-Blanhir et al, 2010). The 6MWT is the best indicator of existing types of functional capacity walking tests for children and can be used to evaluate cardiopulmonary disease. In 2005 a group of authors examined 74 patients with a mean age of 14.2 ± 1.2 years and concluded that the 6MWT can be used to evaluate and evaluate pediatric patients with heart and lung diseases such as cystic fibrosis or bronchiolitis obliterans (Morales-Blanhir et al, 2010)..
