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.
