Interventions

We use MRI to investigate the brain function and structure. Brain function and anatomical networks during executive function tasks and gait speed under dual tasks is measured.

Design outcomes

Primary

Measure	Time frame
1. Research will be conducted by requesting research subjects to answer a questionnaire (exercise items). The questions in the questionnaire are related to the exercise items, and the information to be obtained is as follows. The time required to answer the questions is about 10 minutes. (1) Basic information: gender, age, visual acuity, dominant hand, dominant leg. (2) Questionnaire (exercise items from the basic checklist used in nursing care projects, etc.: Can you climb stairs without leaning against a handrail or wall? Can you stand up from a chair without holding onto anything? Have you fallen in the past year? (Do you have a great deal of anxiety about falling?) (2) The answers to the following questions. 2. The research subjects will be asked to respond to cognitive function tests (Mini Mental State Examination (MMSE) and Trail Making Test (TMT)). The total time required for both tests is about 10 minutes. 3. MRI measurements will be performed on the same subjects. During the MRI measurements, subjects will perform three tasks: an executive function task, a motor task, and a task in which both the executive and motor tasks are performed simultaneously. The executive task will include either the Stroop task or the Flanker task. For the execution task, the task is displayed on a display in the MRI room, and the subject is asked to respond to the task by pressing a button on his/her hand. The exercise task will be a plantar dorsiflexion exercise of the ankle joint. 4. The Time Go Up test (TUG) will be performed as a walking task for the study subjects. The TUG consists of two types of tests: walking only and walking while performing a simple mental arithmetic problem. These measurements will be made in 2 to 3 hours.	—
