This study evaluated the feasibility of mixed consistency foods test in patients with dysphagia which developed after stroke or other brain injuries. The findings of a videofluoroscopic swallow study (VFSS) were compared using single versus mixed consistency foods. Forty-nine patients with stroke or other brain injuries who had no significant abnormal findings in the single consistency food VFSS and started regular hospital diet were recruited for this study. Twenty-five (51%) of the 49 patients showed normal findings whereas 24 (49%) patients showed abnormal findings in the mixed consistency food VFSS. Abnormal findings included posterior spillage of liquid prematurely to pyriform sinus (n = 23), laryngeal penetration (n = 6), subglottic aspiration in the oral preparatory phase of swallowing (chewing), solid components (n = 2), and significant (more than 10%) residue in valleculae or pyriform sinus (n = 2). There was an increased risk of abnormal findings in mixed consistency food VFSS such as aspiration and penetration when a patient showed delayed pharyngeal delay time in single consistency food using liquids. In conclusion, VFSS protocols using mixed consistency foods would be useful before starting regular diet for patients after stroke or other brain injuries.
