This randomized controlled trial aimed to investigate the effects of Action Observation Therapy (AOT) on cognitive function, balance, fatigue, and functional capacity in geriatric individuals. Participants aged 65 years and older were randomly assigned to one of three groups: a control group, an exercise group, or an action observation therapy group. The intervention period lasted 8 weeks. The exercise group received a conventional exercise program, while the action observation therapy group watched exercise videos before performing the same exercises. The control group did not participate in any structured exercise program during the study period. Outcome measures included cognitive function, balance performance, fatigue levels, and functional capacity. The study evaluated whether adding action observation therapy to conventional exercise provides additional benefits in older adults.
