We are writing to inform the readers of the Dysphagia journal of an error in the following paper: Brates D, Molfenter SM, Thibeault SL. Assessing hyolaryngeal excursion: Comparing quantitative methods to palpation at the bedside and visualization during videofluoroscopy. Dysphagia. 2019, 34(3):298–307. This paper compares the results of clinician perception of hyolaryngeal excursion, both on tactile palpation during clinical swallowing examination (CSE) and visual judgement on videofluoroscopy, with objective measurement of hyoid excursion on videofluoroscopy. Hyoid excursion was measured using both peak position measures and displacement measures. An open source spreadsheet tool, previously available at https://www.steeleswallowinglab.ca was used to calculate the position of the hyoid bone or larynx on lateral view videofluoroscopic images. Subsequently, an error was found in the mathematical formula built into the spreadsheet, The original article can be found online at https://doi.org/10.1007/ s00455-018-9927-2. * Susan L.

which resulted in a reversal of the results for the X and Y planes of measurement. Consequently, The discovery of the calculation error means that directional findings reported for the X and Y plane are reversed for the peak hyoid position measures, i.e., the previously reported results for peak anterior position were actually measures of peak superior position, and vice versa.. The reported measures of displacement are unaffected. We would like to take this opportunity to correct one single finding in the analysis: Comparing CSE to objective measurements, we found that peak superior (not anterior) hyoid position was significantly lower in patients judged to have reduced hyolaryngeal excursion (HE) compared to those judged to have functional HE [t(85) = 3.30, p = 0.001]. There was no significant difference in measures of peak anterior or hypotenuse hyoid positions between patients judged to have reduced versus normal HE. These revised results suggest that palpation by the clinicians in our sample was sensitive only to differences in superior hyoid movement. This finding may be related to the increased tactile perceptibility of superior movement. When palpating th
