Avaliação da distância percorrida e velocidade média durante o TC6 em pacientes com diferentes doenças pulmonares

Resumo (EN)

Objective – Evaluate and compare the six-minute walking distance (6MWD) in different lung disorders with the predicted by Enright-Sherrill; as well as the average speed during the six-minute walk test (6MWT). Beyond this, check if age, body-mass index, lung function and average speed can influence the response of 6MWT. Methods – This study included 124 subjects with lung diseases, which have been divided from the lung functions results in three groups: obstructive, restrictive and mixed. The anthropometrics and personal data was evaluated, and then, they were sent to perform the 6MWT, according to ATS. Results– We observed statistical difference (p<0.001) between the 6MWD obtained by the groups and the predicted by Enright-Sherrill. However, we didn’t observed statistical difference among the groups, when we evaluate the 6MWD. In relation to average speed, we didn’t find difference among groups (p=0.666). However, we observed that the time influenced this variable (p<0.001). Also, we observed correlation between the age (r=-0.29) and average speed (r=0.93) with the 6MWD. Already, the predicted 6MWD had correlation with body-mass index (r=-0.84), age (r=-0.36) and average speed (r=0.37). Conclusions – As to lung disorders, there was no interference about six-minute walk distance and predicted 6MWD, as well as about average speed. However, has been observed that age, body-mass index and average speed are the responsible for the response of 6MWT.
