 A functional downward spiral characterized by an impairment of several functional domains, such as strength, muscular endurance and motor-cognitive processes, ultimately leading to restricted mobility and decreased physical activity level is commonly observed in frail older people. Interventions that promote the integration of multisensory, cognitive and motor skills can be able to motivate the older people to remain more active for longer periods, despite their limitations. Exergames involve tasks in virtual environments that combine physical and cognitive demands in an attractive and challenging way. The player is encouraged to achieve goals and overcome limits during the game, providing immediate feedback in relation to their performance. The game experience can create a greater sense of self-efficacy and generate a more positive perception of personal skills, modulated by a positive environment reinforcement, consequently increasing motivation and engagement. This combination of greater sense of self-efficacy and greater motivation could provide a positive and necessary influence for most older people to overcome their limitations and create new lifestyle habits 25, decreasing disability. This study sought to investigate the effectiveness of adding exercises using interactive videogames exergames in improving physical functioning on frail and pre frail older people when compared to conventional physiotherapy.
