Abstract: Objective: To evaluate the effects of structured pulmonary rehabilitation training in school-age children with pneumonia, and provide references for promoting clinical pulmonary rehabilitation of such children. Methods: A total of 126 school-age children hospitalized with pneumonia in a tertiary grade A hospital in Hefei from August 2025 to January 2026 were conveniently selected and equally divided into a control group and an observation group according to admission time, with 63 cases in each group. The control group received conventional rehabilitation training, while the observation group was given structured pulmonary rehabilitation training. Pulmonary function indexes, 6-minute walking distance, Borg Category-Ratio 10 Scale score, post-exercise heart rate change and other indicators were compared between the two groups after intervention. Results: After intervention, FVC%, FEV1%, and FEV1/FVC% in the observation group were 100.43±12.22, 96.07±13.08, 98.15±6.70, respectively, which were significantly higher than those in the control group (92.68±9.49, 85.87±10.60, 95.20±9.61), all differences were statistically significance (P<0.05). The 6-minute walking distance and rehabilitation compliance score in the observation group were significantly higher than those in the control group (P<0.05). There were no significant differences in Borg Category-Ratio 10 Scale score and post-exercise heart rate change between the two groups (P>0.05). Conclusion: Structured pulmonary rehabilitation training can effectively improve pulmonary function, exercise capacity, and rehabilitation compliance in school-age children with pneumonia.
