Objective To evaluate the swallowing function of patients with dysphagia after brainstem injury using manofluorography (MFG), analyzing abnormal biomechanical and kinematic parameters as well any correlation between changes in pharynx upper esophageal sphincter (UES) measured manometrically kinematics hyoid bone.

Methods Thirteen (the patient group) 13 healthy participants control underwent manofluorography. Kinematics during were compared two groups correlations observations analyzed.

Results The group showed significantly lower maximum pressure rate change at base tongue hypopharynx, less anterior displacement, smaller briefer UES opening, but higher minimum relaxation. The duration root elevation hypopharynx was also shorter than group, on average. There a negative displacement relaxation positive group.

Conclusions The concurrent use manometry video-fluorography for evaluating can be an objective effective diagnostic tool comprehensive evaluation function.
