Conditions

Dysphagia, Dysarthria

Interventions

A: Training Group: Three conditions will be perform

with waveform feedback, with numerical value feedback, and without feedback of tongue pressure.

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: Patients with 1) decreasing tongue pressure compared with average in participant's age, 2) Dysarthria or Dysphagia.

Exclusion criteria

Exclusion criteria: Participants can't understand the instruction about oral movement because of dementia, higher brain function disorder and aphasia. Participants could aspirate their saliva during tongue elevation because of severe dysphagia.
