Overview

This study will investigate the effects of dual-task-based high-amplitude functional exercises on balance and functional mobility in older adults with mild cognitive impairment. A total of 36 participants aged 65 years and older will be randomly assigned to either a high-amplitude functional exercise group or a traditional balance and mobility exercise group. Both groups will participate in exercise sessions four times per week for four weeks, with each session lasting 60 minutes. The effects of the exercise programs will be evaluated by assessing balance, functional mobility, dual-task performance, walking performance, fear of falling, and independence in daily activities before and after the intervention.

Interventions

Participants will receive a dual-task-based high-amplitude functional exercise program consisting of high-amplitude functional movements combined with progressively challenging cognitive tasks. The program will be administered 4 times per week for 4 weeks, for a total of 16 sessions, with each session lasting 60 minutes. Exercise intensity will be prescribed as maximal effort, corresponding to 7-8/10 on the Borg Rating of Perceived Exertion Scale. The program will include seated and standing functional exercises, large-amplitude stepping movements, dynamic movements, large-amplitude walking, functional task activities, and complex functional tasks.

Traditional Balance and Mobility Exercise GroupOTHER

Participants will receive a traditional balance and mobility exercise program administered 4 times per week for 4 weeks, for a total of 16 sessions, with each session lasting 60 minutes. Exercise intensity will be moderate, corresponding to 4-5/10 on the Borg Rating of Perceived Exertion Scale. The program will consist of motor tasks without cognitive dual-task components.

Inclusion Criteria: * Living independently/actively in a nursing home. * Diagnosis of Mild Cognitive Impairment (MCI) based on a standardized screening test, with a Montreal Cognitive Assessment (MoCA) score of 18-25. * Ability to walk independently for at least 10 meters without an assistive device or with only a cane/single-point support. * Sufficient vision and hearing capacity to follow dual-task instructions and exercise directions, which may be corrected with glasses or hearing aids. * Stable medical condition that does not prevent participation in the exercise program throughout the study. Exclusion Criteria: * Diagnosis of dementia or severe cognitive impairment based on cognitive screening (MoCA \<17). * Neurological conditions that primarily affect balance, such as Parkinson's disease, residual effects of stroke, multiple sclerosis, or cerebellar ataxia. * Severe osteoarthritis, active inflammatory joint disease, or a history of major orthopedic surgery within the previous 6 months that could limit exercise performance. * Uncontrolled hypertension, heart failure (NYHA Class III-IV), or cardiopulmonary instability causing symptoms during exercise. * Advanced vestibular pathology or severe loss of proprioception in the lower extremities that could be the primary cause of balance impairment.

Primary Outcomes

Dual-Task Timed Up and Go Test

The Dual-Task TUG will assess functional mobility under cognitive load by adding a cognitive task to the standard Timed Up and Go test. Test performance will be recorded as the time required to complete the task.
