Objective: This study was conducted to investigate the effects of reaction time (RT) exercises on functional independence, static balance, fall risk, upper and lower extremity RT, and quality of life in older adults. Methods: Forty participants aged 65-77 years were included in the study. Participants' functional independence was evaluated using the Functional Independence Scale, static balance using the Single-Leg -Squat Test, fall risks using the Morse Fall Scale, lower- and upper-extremity RT's using the Light Trainer Flash Light Exercise System (Model LTV2, Turkey, 2017), and their quality of life using the Short Form-36. RT exercises were performed using the Light Trainer Flash Light Exercise System for six weeks, three days a week. Measurements were repeated after the treatment. Results: In the older adults examined, there was a significant difference between before and after the 6-week exercise protocol in functional independence, static balance, fall risk, upper- and lower-extremity RT, and quality of life (p<0.05). Conclusion: The study showed that a 6-week RT exercise program had positive effects on functional independence, static balance, fall risk, upper- and lower-extremity RT, and quality of life in older adults. The results showed that reaction-time exercises can be added to rehabilitation protocols for older adults and can be used in clinical settings.
