Limited evidence to strong evidence was found for reliability in various chronic conditions .
Little evidence was available for responsiveness and measurement error .
Studies showed large variability in test procedures despite existing guidelines for the performance of the 6MWT .
Evidence for measurement properties of the 6MWT  varies largely among chronic pediatric conditions .
BACKGROUND The Six-Minute Walk Test ( 6MWT ) is increasingly being used as a functional outcome measure for chronic pediatric conditions .
Knowledge about its measurement properties is needed to determine whether it is an appropriate test to use .
PURPOSE The purpose of this study was to systematic ally review all published clinimetric studies on the 6MWT in chronic pediatric conditions .
Objective Assessment of the Cardiorespiratory Function of Adolescents With Idiopathic Scoliosis Through the Six-Minute Walk Test
Study Design . Clinical prospect i ve , r and om study . Objective . Analyze the results of the six-minute walk test ( 6MWT ) in patients with adolescent idiopathic scoliosis . Summary of Background Data . Although it is widely believed that Adolescent Idiopathic Scoliosis ( AIS ) causes cardiorespiratory dysfunctions , there is no report in literature of objective measurements of this restriction in the ventilatory performance during physical exertion . Methods . One hundred twenty-six adolescents matched by gender and age were prospect ively studied at a tertiary teaching institution : 40 patients without spine deformities ( group I – controls ) , and 86 patients with AIS with a spine curve ranging from 45 ° to 138 ° ( group II ) . All patients underwent radiographic evaluations and the 6MWT . Results . Normal controls presented significantly lower mean heart rate and Borg scores , as well as higher oxygen saturation and walked longer distances on the 6MWT . Conclusion . The 6MWT effectively demonstrated the cardiorespiratory restrictions presented by patients with AIS
