Aerodynamic Evaluation and Intervention Effect on Dysarthria / 中国康复理论与实践

ABSTRACT

@#Objective To explore the aerodynamic features and rehabilitation of patients with dysarthria who speak mandarin.Methods From July, 2013 to December, 2016, 45 patients with dysarthria were rehabilitated with physiologic approach (especially the pushing method) for four weeks. The vital capacity, maximum sustained phonation and voicing efficiency were tested before and after intervention.Results After intervention, the peak expiratory airflow, mean sound pressure level during voicing, subglottal pressure and glottal resistance improved (t>2.474, P<0.05), and no significant improvement was found in the expiratory airflow duration, expiratory volume, pitch, maximum phonation time, mean flow rate and vocal efficiency (P>0.05). There was no significant difference in all the indexes among different types of dysarthria (P>0.05).Conclusion The aerodynamic assessment could be a good tool to evaluate the effects on dysarthria, however, it cannot help to define the various type of dysarthria.
