As the global population ages, the prevalence of mild cognitive impairment (MCI) among older adults, which ranges from 5% to 40%, is expected to rise. MCI significantly increases the risk of developing Alzheimer's disease and is associated with a heightened risk of falls, with evidence suggesting that individuals with MCI have a fall risk five times greater than their cognitively intact peers. While cognitive and physical impairments in MCI are recognized, targeted interventions addressing both aspects are needed.
This study aims to evaluate the effectiveness of the Smart±step exergaming program, an interactive system combining cognitive and motor training through computer-based stepping tasks, in reducing risk of falls, fall rate and improving physical, cognitive, psychological, neurophysiological, and quality of life outcomes in community-dwelling older adults with MCI. Previous research indicates that combined cognitive-motor interventions can improve balance and cognitive outcomes, but evidence on their efficacy in reducing falls is limited.
The study will assess whether the Smart±step program, previously shown to be effective in cognitively healthy populations, can also significantly reduce risk of fall, fall rates and enhance overall function in older people with MCI. If successful, the program could offer substantial benefits by lowering fall-related costs and disabilities, with potential for global adaptation and implementation.
