When compared to the 95th percentile time duration to first study maneuver (landmark phase assessment) in standard protocol patients (6.1 min), as many as 31.6% of modified protocol subjects could not obtain their first swallow within this time frame (p = 0.0003). We propose that if the patient cannot refrain from swallowing past 5–6 min, the study should proceed with test swallows rather than wait for a quiet period for the landmark phase recording, which can be subsequently obtained at the end of the study.
