Optimal aging is characterized by older adults maintaining good functional reserves, complete independence, and physiological resilience to stress. Conversely, some elderly individuals exhibit increased vulnerability to stressors and a diminished recovery capacity [1]. Between robust aging and proven dependence lies an intermediate state known as frailty. Frailty is defined as a clinical syndrome reflecting an increased vulnerability to physical and/or psychological stress. It is linked to a slow and latent reduction in functional capacity and is associated with a high risk of adverse events, such as falls, hospitalization, and institutionalization.
