Swallow sound assessment methods showed the following sensitivity and specificity (%) when compared to a videofluoroscopic swallow study:<ul> <li>sonar Doppler: 80.0/100;</li> <li>microphone: 93.9/29.1; and</li> <li>stethoscope with microphone inserted into tubing: 62.0/66.0.</li></ul>Doppler showed the best overall diagnostic accuracy to detect dysphagia while no data was found on accelerometry. Conclusions are based on limited evidence and low methodological quality due to the small number of studies included and small sample sizes. Therefore, further research in this area is warranted.
