Instrument configuration and testing protocol.
| Article | Modality | Instrument | Configuration | Protocol |
|---|---|---|---|---|
| Frakking et al. (2022) | Acoustic | Omnidirectional Condenser microphone | Lateral to the cricoid cartilage at C6 | Two presentations of puree, lumpy mash, chewable solid, extremely thick, moderately thick, mildly thick, slightly thick and/or thin fluids. Only one swallow on thin fluids per patient was used |
| Lee et al. (2006) | Accelerometry | Single-axis accelerometer (EMT 25-C) | Inferoanterior to the thyroid notch | Barium-coated boluses of varying consistencies, ranging from thick puree to thin liquid, were fed |
| Lee et al. (2011) | Accelerometry | Dual-axis accelerometer (ADXL322) for valleculae and pyriform sinuses | Just below the thyroid cartilage | Beginning with a thin liquid 40% weight per volume barium suspension and progressing through nectar- and spoon-thick liquids to solid |
| Airflow pressure | Nasal Cannula with pressure transducer (PTAF Lite) | At the nares | ||
| Merey et al. (2012) | Accelerometry | Dual-axis accelerometer (ADXL322) | Level of cricoid cartilage | Barium-coated boluses of varying consistencies, ranging from thick puree to thin liquid, were fed |
| Park et al. (2022) | Acoustic | Embedded microphone of an iPad | 20 cm from patient’s face | Phonate a single syllable for at least 5 s with comfortable pitch and loudness. No swallowing task |
| Sarraf Shirazi et al. (2014) | Acoustic | Microphone (ECM-77B) | On the suprasternal notch of trachea | Different type of solid/liquid food. Type and order determined by speech pathologist |
| Sarraf Shirazi et al. (2012) | Acoustic | Microphone (ECM-77B) | On the suprasternal notch of trachea | Different type of solid/liquid food. Type and order determined by speech pathologist |
| Sejdic et al. (2013) | Accelerometry | Dual-axis accelerometer (ADXL322) | Anterior to the cricoid cartilage | 5 mL sips of thin liquid barium |
| Acoustic | Lapel microphone | Around the neck | ||
| Shu et al. (2022) | Accelerometry | Tri-axis accelerometer (ADXL327) | Anterior to the cricoid cartilage | Swallowing assessment in clinical routine |
| Acoustic | Contact microphone (C411L) | Slightly below the accelerometer anterolateral to larynx |
