Swallowing sounds in cerebral palsy using Doppler sonar

Dysphagia is a very common symptom in children with cerebral palsy and may be associated with aspiration, leading to chronic lung problems and recurrent pneumonia. Our challenge was to study and compare swallowing sounds in children with and without cerebral palsy using Doppler sonar simultaneously with videofluoroscopy, analysing possible differences between the variables frequency, intensity and time.
