In order to better cope with the issue of population aging, the World Health Organization (WHO) proposed a new conceptual model of intrinsic capacity in 2015, aiming to pay more attention to the functional status of the elderly, and thus intrinsic capacity becomes a new direction of geriatric research.

In this article, we reviewed the current assessment tools of intrinsic capacity in order to provide a reference for clinical medical staff to assess intrinsic capacity.
