Mit akar kideríteni a vizsgálat

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:

A vizsgálat 3 csoportja

• Oral Motor and Cognitive Dual-Task Training (OMCDT) intervention groupA vizsgált kezelés

  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.

• Control GroupNincs vizsgálati kezelés, összehasonlításként

  The participants in the control group will receive usual care

• Oral motor exercise groupA vizsgált kezelés

  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.
