Abstract | |||||||||
| Purpose. To compare the effect of slow motion and real time review on the accuracy of judgments made during interpretation of radiographic swallow studies. Methods. Video swallow sequences from 6 different patients with varying degrees of dysphagia were prepared for viewing in real time and slow motion formats. Using a repeated measures model, 133 clinicians with a range of experience viewed swallow sequences under either slow motion or real time conditions during an initial session. A second session was held 1.5 hours later where the clinicians viewed the same segments in the opposite viewing format from the first. During each session the clinicians were asked to apply scaled scoring for penetration/aspiration and to identify the pathophysiology of the disordered swallow. Clinicians' individual responses were compared to responses from an expert panel of raters and were then converted to a cumulative total correct score (accuracy). Results. There was a significant difference between accuracy for slow motion and real time viewing across the entire group (p | |||||||||
