Lammers N, van Hoesel MHT, van der Kamp M, et al. - Whether exercise-induced bronchoconstriction (EIB) in asthmatic children can be effectively detected using the Visual Analog Scale (VAS) for dyspnea, was investigated. Researchers also evaluated the value of combining (C-)ACT (Asthma Control Test) results with VAS scores. Participants were 75 asthmatic children (mean age 10.8 years), in whom, a standardized exercise challenge test (ECT) was performed in cold and dry air in order to measure EIB. VAS dyspnea scores were reported by children and parents, both prior to and after the ECT. Via (C-)ACT, they evaluated asthma control. They found a moderate correlation of alterations in VAS scores of children and parents with decline in forced expiratory volume in 1 second. They concluded that VAS could serve as an effective additional tool for detecting EIB in children. For detecting and excluding EIB, high efficacy of a reported difference in VAS scores of ≥ 3 after a standardized ECT combined with low (C-)ACT scores was suggested.
