The purpose of this study is to investigate the effect of the dual task exercise program on cognitive and physical function in the elderly with mild cognitive impairment.
All participants provided written informed consent before study participation. A total of 12 community-dwelling participants were randomized either to the exercise group or to the control group.
The exercise group underwent 8-week, 3 times a week, 60-minute group exercise sessions, which were comprised of moderate-to-high intensity exercise and simultaneous cognitive tasks. They also performed moderate-intensity home aerobic exercises for at least 60 minutes per week. The control group performed 60-minute light intensity home exercise, 4 times a week for 8 weeks.
3,872 studies on the registry are indexed under Cognitive Dysfunction; 1,119 are open to participants now.
This study's enrollment of 12 is below the median of 64 across 2,794 interventional studies indexed under Cognitive Dysfunction.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Dual task cost in Timed up and go (TUG)
Participants completed both single-task (ST) and dual-task (DT) tests at baseline and post-intervention. For a ST condition, participants performed motor task only such as Timed up and go (TUG). TUG measured the time of taking to rise from a chair, walking three meters, turning around 180 degrees, walking back to the chair, and sitting down while turning 180 degrees. For a DT condition, participants performed TUG while performing serial 3 simultaneously. Serial 3 is descending subtraction task, where the patient counts down from one hundred by threes. In the DT condition, participants were given no instruction regarding the prioritization of one task over the other. We calculated TUG duration in both conditions. Dual task cost(DTC) were calculated as a percentage as follows: (%DTC) = \[dual task duration or speed - single task duration or speed\] / \[single task duration or speed\] \* 100%. The lower DTC indicates efficiency in cognitive-motor interplay and good dual task ability.

Dual task cost in 10-meter walking test
Participants completed both single-task (ST) and dual-task (DT) tests at baseline and post-intervention. For a ST condition, participants performed motor task only such as 10-meter walking test (10MWT). 10MWT is a performance measure used to assess walking speed over a short distance. For a DT condition, participants performed 10MWT while performing serial 3 simultaneously. Serial 3 is descending subtraction task, where the patient counts down from one hundred by threes. In the DT condition, participants were given no instruction regarding the prioritization of one task over the other. We calculated 10MWT gait speed in both conditions. Dual task cost(DTC) were calculated as a percentage as follows: (%DTC) = \[dual task duration or speed - single task duration or speed\] / \[single task duration or speed\] \* 100%. The lower DTC indicates efficiency in cognitive-motor interplay and good dual task ability.

Korean Montreal Cognitive Assessment (MoCA-K)
MoCA-K is a screening test to assess cognitive functions such as attention, concentration, execution, memory, vocabulary, visual space, abstraction, and calculation. MoCA-K is a test for mild cognitive impairment and it takes about 10 minutes to run. It assesses cognitive functions such as attention, concentration, execution, memory, vocabulary, visual space, abstraction, calculation and support. Of a maximum 30 points, a score of 25 or higher is considered normal.
