Aging is defined by a reduction in physiological functions, which results in an elevated susceptibility to disease. Encouraging active aging through structured exercise programs becomes increasingly important as the elderly population expands. Telehealth is a promising solution for elevating physical activity levels among institutionalized elders. 200 elderly participants aged 60-75 years were divided into two groups for this experimental study: an experimental group that received telemonitored Otago exercises and a control group that participated in supervised group exercises. Both groups participated in 45-minute sessions three times a week for a period of 12 weeks. The Senior Fitness Test was employed to evaluate physical fitness both before and after the intervention. In the experimental group, there were substantial improvements in the following: chair stand (p<0.001), arm curl (p<0.001), 2-minute step test (p<0.001), chair sit reach (p<0.001), back itch (p<0.001), and up and go test (p<0.001). In contrast, the control group exhibited less significant improvements. The telemonitored group exercise was found to be a highly effective alternative to traditional supervised exercises, as it substantially improved the mobility and strength of the lower body in institutionalized elders.
