body systems. Body function and structure impairments are related to significant

deviation or loss.

 The activities and participation component collectively covers the complete range

of individual and societal functioning and disability. The model captures the major

actions of all people, regardless of culture or lifespan. Activity is the execution of a task

or action that is completed by an individual in a uniform environment. Activity

limitations are difficulties a person may have in executing activities. Activity includes

self-care, mobility, learning and applying new knowledge, general tasks and demands,

and communication. Participation is the involvement in a life situation in an individual's

current environment. Restrictions in participation are problems a person may experience

in involvement in life situations. Participation includes domestic life, interpersonal

interactions and involvement in relationships, major life areas, and community, social,

and civic life. Activities and participation have two qualifiers within the model. Capacity

is the completion of an item in a neutral or standard environment and focuses on how an

individual actually completes the task. Performance is related to completing the same

item during daily life, at home and in the environment. Capacity limitations indicate the

discordance between capacities of people with and without health related condition.

Performance limitations indicate a need for intervention at the environmental level.

 Environmental and personal factors include external features of the physical, social,

and attitudinal environment in which people live and conduct their lives. Products and

technology, natural environments, human-made changes to the environment, support and

relationships, attitudes, and services, systems, and policies are all aspects of

environmental and personal factors.
