Background: The irreversible alterations in pulmonary functioning have serious implications. The improvement of cognitive and executive processes may be essential therapeutic objectives since they can directly affect children's functioning abilities and quality of life. Objectives: The purpose of this study was to find out if there is a relation between executive function domains and pulmonary functions in Egyptian school-aged children. Methods: An observational cross-sectional (correlational) study including 240 school aged children of both sexes, with age ranged from 8-12 years. working memory, inhibitory control, and cognitive flexibility (executive function domains) were evaluated using the Tower of Hanoi, Eriksen flanker test and Trail-making test B respectively. Moreover, pulmonary functions have been investigated through (forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow rate (PEFR), and FEV1/FVC were measured by the spirometer. Results: There was a significant correlation between all measurable pulmonary function tests (FVC, FEV1, PEF, and FEV1/FVC) andexecutive function domains (working memory, inhibitory control and cognitive flexibility). Conclusion: There was a correlation between pulmonary functions and executive functions in Egyptian school children. pulmonary rehabilitation activities can be used by physical therapists to help children with their executive function.
