Oral Motor and Cognitive Dual-Task Training (OMCDT) Program for Improving Oral and Cognitive Functions Among People With Oral Frailty (OMCDT)
Oral Motor and Cognitive Dual-Task Training (OMCDT) Program for People With Oral Frailty for Improving Oral and Cognitive Functions: a Feasibility Study
The goal of this clinical trial is to proposes a novel Oral Motor and Cognitive Dual-Task Training (OMCDT) program that combines both oral motor exercises and cognitive tasks to improve brain and oral function at the same time. It will also learn about the safety of drug ABC. The main questions it aims to answer is:
Does the OMCDT training can improve the oral and cognitive functions?
Participants will:
Take the OMCDT training once a week for 32 weeks Visit the lab twice in the intervention period (16-week, 32-week) for checkups and tests

実験的:Oral Motor and Cognitive Dual-Task Training (OMCDT) intervention group
The participants will be instructed to relax as much as possible, and the surrounding environment will be set up as monotonous as possible.
Only one PC, one (NIRS) with its accessories will be placed on a table.
Particularly, at Week 1, Week 16 and Week 32, participants will be instructed to sit in a comfortable chair in front of the PC and wear the NIRS device.
The intervention will be carried out follow the modified OCMDT protocol.
Each weekly session includes 28 small training activities lasting about 40 min for 32 weeks.

|
介入なし:Control Group
The participants in the control group will receive usual care
|
|
|
実験的:Oral motor exercise group
Participants in the oral motor exercise group will receive evidence-based oral motor exercises without cognitive training.
The intervention will include four components: tongue-lip coordination exercises, tongue muscle strengthening exercises, lip and cheek muscle strengthening exercises, and mastication exercises.
Each component will be repeated for seven rounds, with a 10-second rest interval between rounds.
The intervention will be delivered once per week.

Self-reported oral health
時間枠:Baseline, 16-week, 32-week
|
The self-reported oral health will be evaluated by General Oral Health Assessment Index (GOHAI).
the Chinese version of GOHAI include 12 items There are five response categories for each question (l=always, 2=often,3=sometimes,4=seldom,and 5=never).
The GOHAI score was computed by adding up the scores of the responses to the 12 questions and a higher score indicates a better reported oral health status.
