Oscillometry is more feasible than spirometry in children with neuromuscular diseases

<title>Extract</title> Pulmonary Function Testing (PFT) plays a critical role in the management of paediatric patients with Neuromuscular Diseases (NMDs) [1]. NMDs impact respiratory function to varying degrees due to their effects on the respiratory drive, muscles, and the neuromuscular junction [2]. Regular assessment of respiratory function, particularly through the measurement of Vital Capacity (VC) <italic>via</italic> spirometry, is recommended by national guidelines to monitor disease progression and identify early signs of respiratory compromise [3]. However, performance of volitional PFT, such as spirometry, requires an ability to understand and physically perform challenging respiratory manoeuvres. In children with NMDs, this may become more difficult as disease progresses, reducing both accuracy and reproducibility [4, 5].
