 A score between 5 and 9 shows seniors still independent, but with reduced physical performance, which can therefore be regarded as fragile and high risk, deserving of special attention and specific interventions, acts to reduce the risk of adverse consequences. Data in the literature confirm that the SPPB correlates with the risk of developing disability in BADL and mobility, in proportion to the decrease of the SPPB score, regardless of age, sex and presence of certain chronic diseases. The SPPB score then emerges as a powerful predictor of disability and mortality in the elderly population. The battery SPPB proved to be a valid predictor of prognosis in heart patients: in elderly hospitalized for acute exacerbation of chronic heart failure, the SPPB score at discharge was able to predict the long-term mortality. This assessment thus appears to be safe and feasible in hospitalized patients: test will be performed in patients with hemodynamic stabilization prior to discharge.
