What is the ICF model, and how does it influence PT evaluation and prognosis?

• A. It frames body function/structure, activity/participation, and contextual factors for assessment and prognosis.
• B. It is a classification system for medications.
• C. It replaces disease labels with functional terms.
• D. It only considers body structure.

Answer: (C)

The ICF model describes health and functioning across three interconnected areas: body functions and structures, activities and participation, and contextual factors (environmental and personal). This framework guides PT evaluation by linking a patient’s impairments to real-life tasks and roles. You assess how limitations in body function translate into activity restrictions and participation challenges within the person’s actual environment, and you identify contextual facilitators or barriers that can influence outcomes. For prognosis, you consider how these factors interact to affect potential improvement and the patient’s ability to achieve goals, not just the medical diagnosis itself.

The other statements miss key ideas: it is not a classification system for medications, it does not replace disease labels with functional terms, and it does not focus only on body structure.
