Objective: The present study is to develop an algorithm for screening only swallowing movements out of various laryngopharyngeal movements using ultrasonic Doppler sensor and microphone. Background: Only swallowing movements need to be discriminated out of various laryngopharyngeal movements (e.g., vocalization, cough) measured by a swallowing measurement system using ultrasonic Doppler sensor for specialization in swallowing research. Method: laryngopharyngeal movement and audio signals during swallowing, cough, vocalization, respiratory, and neck movement were simultaneously measured three times to five healthy adults by ultrasonic Doppler sensor and microphone. A swallowing screening algorithm calculating movement-to-audio ratio applied with swallowing apnea was developed for screening only swallowing movements. Results: Vocalization, cough, and respiratory movements were perfectly discriminated with swallowing movements by the swallowing screening algorithm; however, neck rotation movements 73% due to occurring no laryngopharyngeal movements. Conclusion: The swallowing screening algorithm developed in the study could discriminate swallowing movements from vocalization, cough, and respiratory movements. Application: The swallowing screening algorithm can be applied to the swallowing measurement device and contribute to accurate evaluation of swallowing movements for patients with dysphagia.
