It covers functionality as activity and participation, that is, what human beings can do in different situations or under the influence of different environments, for example. Each category or construct is related to a set that must be completed by qualifiers, numbers that indicate the magnitude of a problem within a specific category. In general, the user must select the categories and qualifiers that identify and express each case.11 The classification must be made based on the multidirectional model of functionality, which integrates the different dimensions, establishing relationships between the environment, the performance of activities and social participation.
