Method: participants with and without asthma were included in the development and validation phases, respectively. The PAY test includes five activities: transition from sitting to standing, walking 10 meters, step climbing, shoulder extension and flexion, and star jumps. Participants also underwent the Pediatric Glittre test (TGlittre-P), modified shuttle test (MST), and cardiopulmonary exercise test (CPET). Outcomes: PAY test time, oxygen uptake (VO2peak), and distance walked in the MST. Results: 10 healthy volunteers, age 14 (7 -16) years old were included in the development phase and 32 participants with asthma, age 10 (8 -13) years old, in the validation phase. All participants were able to complete the PAY test. The PAY test elicited greater physiological responses (VO2peak 33.5 ± 6.9ml/kg) than TGlittre-P (VO2peak: 27.4 ± 9.0ml/kg), but lower than the MST (VO2peak: 48.9 ± 14.2ml/kg) and CPET (VO2peak: 42.0 ± 8.8ml/kg), p < 0.05. There was moderate correlation between the PAY test time and the TGlittre-P time (r = 0.70, p < 0.001) and distance walked in the MST (r = -0.72, p < 0.001). The PAY test time was longer in participants with asthma than in healthy participants (3.3 1.1 min vs. 2.1 ± 1.0 min, p = 0.01). The PAY test was reproducible (ICC 0.78, CI 95% 0.55–0.90, p < 0.001), with a mean difference of -0.22 (0.90–0.43 min). Conclusions: The PAY test is a valid and reproducible tool for assessing functional performance in children and adolescents with asthma.FootnotesCite this article as Eur Respir J 2022; 60: Suppl. 66, 4313.This article was presented at the 2022 ERS International Congress, in session “-”.This is an ERS International Congress abstract.
