We included 60 stroke patients (30 tube-feeding-dependent and 30 on regular oral intake) and 30 healthy controls. An additional 10 healthy people were recruited to assess the reliability of SUS. Measurements of hyoid bone displacement using videofluoroscopic swallowing study (VFSS) and SUS were compared for 12 stroke patients to assess the correlation between the two methods. Changes in tongue thickness and hyoid bone displacement were significantly less in the tube-feeding group. Those with a tongue thickness change of less than 1.0 cm and hyoid bone displacement of less than 1.5 cm were likely to be tube-feeding. SUS showed good intra-rater/inter-rater reliability and correlated well with VFSS measurement. SUS can be an adjunct assessment tool of swallowing. ? 2012 World Federation for Ultrasound in Medicine & Biology.[SDGs]SDG3Assessment tool; Bone displacement; Dysphagia; Healthy controls; Healthy people; Oral intake; Oropharyngeal; Stroke; Stroke patients; Feeding; Tubes (components); Ultrasonics; Ultrasonography; Biological organs; adult; aged; anthropometric parameters; article; controlled study; diagnostic test accuracy study; diagnostic value; disease severity; dysphagia; echography; female; fluoroscopy; functional assessment; human; hyoid bone displacement; interrater reliability; major clinical study; male; medical parameters; oropharyngeal dysphagia; patient assessment; priority journal; reproducibility; sensitivity analysis; stroke patient; submental echography; swallowing; tongue thickness; tube feeding; validity; videofluoroscopy; Aged; Barium Sulfate; Case-Control Studies; Contrast Media; Deglutition Disorders; Female; Fluoroscopy; Humans; Hyoid Bone; Male; Middle Aged; Reproducibility of Results; Sensitivity and Specificity; Statistics, Nonparametric; Stroke; Tongue; Video Recordingjournal article10.1016/j.ultrasmedbio.2012.04.017226985072-s2.0-84864605870
