Introduction
 Elderly individuals
 Dementia disorders
 Degenerative
 Alzheimer 's disease
 Parkinson's disease
 Etc.
 Vascular
 Post-stroke vascular dementia
 Dementia with small vessel diseases
 Reversible
 < 5~10%
3
Introduction
 Cognitive impairment
 Dual-Task (DT)
 Physical exercise training
 Balance
 Mobility
 Walking
4
Introduction
 Dual-Task Tai Chi (DTTC)
 Using Kinect
 Include
 DT
 Balance
 Cognitive ability
 12-week program of DTTC training
 A total of 41 elderly individuals
 Training group: n = 26
 Control group: n = 15

Methods
 Participants



Age>= 65
Independent ambulation
Measurement of physical fitness
Rapid Dementia Screening Test(RDST)
 scored 8 or greater

Methods
 Interventions
 Control group(CG)
 75-min standardized training
 Training group(TG)
 75-min standardized training
 5-min DTTC training
9
Methods
 Outcome measures
 Trail-making test (TMT)
 Visual-scanning task
 Cognitive flexibility
 Verbal fluency test (VFT)
10
Results
 Study population
 A total of 41 of the 48 selected subjects
 TG: n = 26, CG: n = 15

Results
 ΔTMT
13
Discussion
 Using ΔTMT score significantly improved
after DTTC training.
 DTTC training, has a positive impact on DT
ability and the prevention of falling.
 TMT-A & B scores were not significantly
improved.
 VFT was not significantly changed.
14
Discussion
 Limitations
 Interventions
 Not due solely to the DTTC
 Health issues
 Fall risk minimization
15
Conclusion
 ANCOVA results of ΔTMT reveal
 Group x time
 Statistically significant
 DTTC training
 Effective to improve Executive Cognitive
Functions
