Abstract:
Objective To analyze temporal and kinematic parameters of video fluoroscopic images of swallowing using a digital acquisition and analysis system and to verify the reliability of this method.Methods Eighteen patients with dysphagia were requested to completed six swallows (3 ml and 5 ml of thin liquid, thick liquid, and paste mixed with 600 kg/m3 barium sulfate suspension) in the natural sitting position.Video fluoroscopy was used to measure the oral transit times, soft palate elevation times, hyoid movement times, laryngeal closure times, cricopharyngeal muscle opening times, hyoid anterior movement (HAM) , hyoid superior movement (HSM) , cricopharyngeal muscle opening diameter and pharyngeal constriction rate.Each was extracted from the videos four times by two raters working separately with an interval of 4 weeks between the sets of evaluations.Results Reliability varied among the different observations.HAM and HSM showed inter-rater reliability between 0.41 and 0.60 and intra-rater reliability between 0.61 and 0.80.The other observations all demonstrated acceptable reliability.Conclusion The self-designed digital acquisition and analysis system tested showed acceptable reliability and could be applied to analyze swallowing function clinically.
