Sharma N, Sree BS, Aranha VP, et al. - Given that six minute walk test (6MWT), Spirometry and chest expansion are employed regularly to determine the status of functional capacity as well as pulmonary function prior to as well as after operation, researchers herein investigated if Functional capacity Ten meter walk test (10mWT), Nine stair climbing test (9SCT), pulmonary function [Spirometry parameters (FVC, FEV1, FEV1/FVC ratio and PEFR)] and chest expansion have correlation among children receiving open abdominal surgery. Participants were 18 children aged 5–17 years old receiving open abdominal surgery. Findings showed the presence of a moderate correlation between pulmonary function and chest expansion, but functional capacity correlated poorly with pulmonary function and chest expansion. Therefore, individual importance of all the outcome measures (6MWT, 10Mwt, 9SCT, Spirometry, and Chest expansion) was suggested.
