简要总结
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.

入选标准
- •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-
- •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.
排除标准
- •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.

结局指标
主要结局
Dual-Task Timed Up and Go Test
时间窗: Baseline to post-intervention (4 weeks)
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.
Mini-BESTest
时间窗: Baseline to post-intervention (4 weeks)
The Mini-BESTest will be used to assess balance performance across anticipatory postural control, reactive postural control, sensory orientation, and dynamic gait. The scale consists of 14 items scored from 0 to 2, with a maximum total score of 28. Higher scores indicate better balance performance.
Five Times Sit-to-Stand Test
时间窗: Baseline to post-intervention (4 weeks)
The Five Times Sit-to-Stand Test will be used to assess lower-extremity muscle strength and functional capacity. The time required to complete five full sit-to-stand repetitions will be recorded.
次要结局
