Hyoid Peak Position Calculation 

In links provided below, you will find instructions for measuring hyoid peak position. Recent data from research in our lab suggests that measurement of a single point (peak position), relative to a fixed point on the spine (anterior inferior corner of the C4 vertebra), is adequate for capturing variations in hyoid movement during swallowing across different conditions.

These measurements are described in a recent publication:  Molfenter, S. M. & Steele, C. M. (2014). Use of an anatomical scalar to control for sex-based size differences in measures of hyoid excursion during swallowing. Journal of Speech-Language Hearing Research. DOI:10.1044/2014_JSLHR-S-13-0152

Hyoid Displacement Calculations

In the links provided below, you will find instructions for measuring hyoid displacement between a rest and a peak position. While recent data from research in our lab suggests that measurement of a single point (peak position) is adequate for capturing variations in hyoid movement during swallowing across different conditions, you may still wish to measure displacement between a rest and peak position. In this case, we recommend that you choose a rest position at the end of the swallow, after the hyoid has returned to baseline; we call this frame the “Swallow Rest” frame.
