Acoustic analysis of oropharyngeal swallowing using Sonar Doppler.

The evaluation of swallowing in patients with spinocerebellar ataxia and oropharyngeal dysphagia: A comparison study of videofluoroscopic and sonar doppler

INTRODUCTION  Spinocerebellar ataxia (SCA) is a degenerative disease that can cause loss of coordination of voluntary muscle movement such as that required for swallowing. AIMS  The purposes of this cross-sectional and comparative case study were: (1) to assess the severity of dysphagia through a videofluoroscopic swallow study, and (2) to compare differences in frequency, intensity, and dura...

Doppler sonar analysis of swallowing sounds in normal pediatric individuals.

UNLABELLED Among the methods for assessing swallowing sounds - videofluoroscopy modified barium study, fiberoptic swallowing endoscopy, neck auscultation through a microphone, accelerometer and, more recently, the Doppler sonar - we have chosen the latter. AIM to analyze swallowing sounds by cervical auscultation using Doppler sonar, in a population between 2 and 15 years without oro-pharynge...

Characterization of Swallowing Sounds with the Use of Sonar Doppler in Full-Term and Preterm Newborns

Introduction Technological advances have provided a large variety of instruments to view the swallowing event, aiding in the evaluation, diagnosis, and monitoring of disturbances. These advances include electromyography of the surface, dynamic video fluoroscopy, and most recently sonar Doppler. Objective To characterize swallowing sounds in typical children through the use of sonar Doppler. Met...

Doppler sonar analysis of swallowing sounds in normal pediatric individuals Summary

Diagnostic validity of methods for assessment of swallowing sounds: a systematic review.

INTRODUCTION Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. OBJECTIVE This...
