| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Dual task cost in Timed up and go (TUG) | Baseline | 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. |
| Primary | Dual task cost in 10-meter walking test | Baseline | 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. |
| Primary | Dual task cost in Timed up and go (TUG) | immediately after the 8-week intervention | 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.

| Secondary | Korean Montreal Cognitive Assessment (MoCA-K) | Baseline | 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. |

| Secondary | Korean Mini Mental Status Examination (K-MMSE) | Baseline | K-MMSE is a screening test for dementia that can evaluate various areas of cognitive function in a short time of 5 to 10 minutes such as time orientation, place orientation, memory, attention and calculation, understanding and judgment, and language. Of a maximum 30 points, a score of less than 24 is considered dementia. |

| Secondary | Computerized cognitive test(digit span test, visual learning test, verbal learning test, the Stroop Color and Word test, Boston naming test, trail making test, and verbal fluency test) | Baseline | Computerized cognitive test is a test method which quantitatively measures patients' cognitive problems in a systematic and standardized manner using a computer. Various neurocognitive function tests such as attention, memory, memory-motor coordination, and comprehensive cognitive thinking ability are possible through computerized cognitive test. Card sorting test, digit span test, visual learning test, verbal learning test, and Stroop word color test were conducted for precise cognitive function evaluation. |
