Inclusion criteria
Inclusion criteria: Participants must be able to understand the study procedures, voluntarily agree to participate, and provide written informed consent. Participants must have intact cognitive function, defined as a Clinical Dementia Rating (CDR) score of 0, and be able to sufficiently understand the experimental instructions and perform the assessments of oral, tongue, and masticatory functions as instructed. Participants must have oral and tongue functions that allow participation in the vibration stimulation experiment, including basic sensory and motor abilities of the tongue.
Exclusion criteria
Exclusion criteria: Individuals with cognitive or psychiatric impairments, including severe cognitive impairment, severe psychiatric disorders, or alcohol or drug dependence, who are unable to understand the experimental instructions or complete the measurements. Individuals taking medications that may affect oral sensation or tongue muscle function, such as sedatives, anesthetics, or muscle relaxants. Any other individuals deemed unsuitable for participation by the principal investigator, including those with markedly poor general health or a limited life expectancy.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measures are changes in the cough reflex threshold, swallowing reflex latency, tongue-related functional parameters, and masticatory performance. The secondary outcome measures include the effects of baseline characteristics on the intervention outcomes. | — |
