In the ICF framework, the focus is on the actions people perform. The term Activities describes the execution of tasks and actions, including walking, reaching, and activities of daily living. These are concrete actions a person carries out in daily life, not the underlying body parts or their functions.

Body Structure and Body Function refer to the anatomical parts and the physiological processes that support those actions, but they don’t define the tasks themselves. Environmental Factors are the external influences that can help or hinder performance, such as assistive devices or social support, rather than the category of the task.

So, walking, reaching, and activities of daily living fit best under the Activities domain because they are the actual tasks people perform, whereas the other domains describe the bodily components or the external context around performing those tasks.
