Communication n° 341 Introduction By listening our Duchenne Muscular Dystrophy (DMD) patients' speech, we noticed a peculiar phonatory profile. We wondered whether it was a proper disfluency and if it could be related to the remarkable impairment in respiratory function experienced by Neuromuscular disorders (NMDs) patients. In fact lung volumes and breathing patterns used during speech differ from those of quiet breathing respiration. NMDs such as DMD and Spinal Muscular Atrophy (SMA) are characterised by progressive loss of respiratory muscle strength, and reduction of pulmonary and chest wall compliance resulting in progressive restrictive disventilatory syndrome develops. The possible relations between these aspects have not previously investigated in NMDs children Aims To analyse speaking and breathing patterns during spontaneous language and reading of brief rigmarole and nursery-rhyme in a group of DMD and SMA patients compared to healthy control subjects and to assess any relationship with respiratory function impairment. Methods 28 italian language school children (12 children affected by DMD, 5 affected by SMA and 11 healthy control subjects) were enrolled and completed the evaluation of patterns of language and fluency during prolonged aloud speech production. All the patients performed a lung function assessment consisting in spirometry with detection of static lung volumes and respiratory muscle strength by means of mouth maximal inspiratory and expiratory pressure and a on-line recording of respiratory rate during speech. Results Compared to healthy control subjects patients with DMD and SMA showed altered speech function expressed by disfluency index in spontaneous language, independently of underling disease. Patients showed different breathing patterns across speaking trials with an increased respiratory rate after the reading task. The respiratory rate's increasing pattern after the reading task is related to impairment of Vital Capacity. Conclusions Altered speech function expressed by disfluency index can occur in patients with NMDs; disfluent speech impairment is related with respiratory function impairment independently of underlying disease. The reading of a text could potentially be considered as an endurance task in the respiratory assessment of school children affected by NMDs.
