Summary
Two normal swallowing patterns were identified: the predominant "tipper" and the "dipper" type. Dipper swallows, where the tongue dips under the bolus, were more common in older adults, impacting oral phase swallowing evaluations.
Area of Science:
- Oropharyngeal physiology
- Deglutition biomechanics
Background:
- Understanding the normal oral phase of swallowing is crucial for diagnosing dysphagia.
- Previous research has primarily focused on the dominant swallowing pattern.
Purpose of the Study:
- To characterize the normal patterns of the oral-swallowing phase.
- To identify variations in swallowing initiation and bolus manipulation.
Main Methods:
- Observational study involving participants with normal oral motor function.
- Characterization of swallowing patterns based on tongue movement and bolus position.
Main Results:
- The predominant swallowing pattern was the 'tipper' type, initiating with the tongue tip against incisors.
- A 'dipper' type swallow, involving tongue depression under the bolus, was also observed.
- Dipper swallows were more prevalent in individuals aged 60 and older.
Conclusions:
- Normal swallowing involves at least two distinct patterns: tipper and dipper.
- The prevalence of dipper swallows increases with age.
- Recognizing both patterns is essential for accurate assessment of normal and abnormal oral swallowing phases.
