NCT03024333 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

Last updated 2023-09-15

No results posted yet for this study

Summary

This study is aimed to establish and identify the normal pattern of swallowing sounds and analyze swallowing sounds of different textured foods and viscous liquids in healthy subjects to provide clinical evidence to update dysphagia patients' food.

Conditions

  • Deglutition Disorder

Interventions

OTHER

Investigators will use the blender to prepare different viscous foods and liquids. Then, a sound detection device will be attached on the participant's neck. The device will record three times of swallowing sounds at three placements (Apleft, Apright, B) separately with participants' head-trunk in neutral position and also record sounds in the neck such as breathing sound, throat clearing and cough sounds. Participants will use 5 ml spoon to intake different viscous foods or liquids. The conversation will also be recorded using a Sony recorder (ICD-SX713) in each data collection session. The voice recording will not be analyzed, which only provides the additional information about which foods or liquids subjects swallow or at which placement sensor records swallowing sounds.
