Computer-assisted assessment of hyoid bone motion from videofluoroscopic swallow studies.

Videofluoroscopic examination of swallowing remains the standard for evaluation of patients with swallowing complaints. Although attempts have been made to objectify aspects of the study, findings from the study are largely subjective and reliant on clinician training and judgment leading to considerable inter-rater variability. We describe a computerized image analysis program designed to objectify one component of the swallow study, the movement of the hyoid bone.
