Does Cognitive-Physical Dual-Task Training Have Better Clinical Outcomes than Cognitive Single-Task Training Does? A...

Area of Science:

• Gerontology
• Neuroscience
• Rehabilitation Science

Background:

• Mild cognitive impairment (MCI) affects executive function and daily living activities in older adults.
• The efficacy of dual-task training for MCI is debated.
• Developing effective interventions for MCI is crucial for maintaining independence.

Purpose of the Study:

• To develop and validate a cognitive-physical dual-task training program.
• To assess the program's impact on executive function in older adults with MCI.
• To compare dual-task training with single-task training.

Main Methods:

• Participants with MCI were randomized into an experimental group (cognitive-physical dual-task training) or a control group (cognitive single-task training).
• Both groups underwent 16 training sessions over 8 weeks.
• Executive function and instrumental activities of daily living were assessed using the EFPT-K, FAB, and K-IADL.

Main Results:

• No significant baseline differences were observed between the experimental and control groups.
• The experimental group demonstrated significant improvements in the EFPT-K, FAB, and K-IADL compared to the control group.
• Effect sizes for improvements in the experimental group were moderate to large.

Conclusions:

• Cognitive-physical dual-task training is clinically effective for enhancing executive function in older adults with MCI.
• The training program also improved instrumental activities of daily living.
• This dual-task approach represents a promising intervention strategy for managing MCI.
