Summary of "FisioTEDrapia 2018. MIGUEL BENITO. Clasificación Internacional del funcionamiento"

Purpose and problem

A medical diagnosis (for example, “incomplete spinal cord injury”) describes the health condition but does not fully explain a person’s functioning, activities, or participation in life.
Clinicians need a framework to connect health conditions with real-life functioning to guide evaluation, treatment goals, and outcome measurement.

The International Classification of Functioning, Disability and Health (ICF) was created by the World Health Organization (WHO) in 2001 to link health conditions with functioning and disability.
The ICF uses a systemic (interactional) model: body structures & functions, activity, participation, environmental factors, and personal factors interact to determine overall functioning or disability.
It provides a common international language and codes for describing functioning (for example, the mobility chapter code 4500 = walking short distances: <1 km, through rooms/hallways or short outdoor distances).

The ICF frames disability and functioning as the result of dynamic interactions between a person’s health condition and contextual factors.

Body structures and body functions
- Anatomical parts and physiological/psychological functions relevant to an activity (e.g., ankle, muscles, tone, joint stability).
Activity
- Execution of a task (e.g., walking).
Participation
- Involvement in life situations or social contexts (e.g., shopping, playing sport, leisure). Participation is an activity placed in a social or meaningful life context — the “lived experience.”
Environmental factors
- Physical, social, and attitudinal elements that can facilitate or limit performance.
Personal factors
- Individual preferences, motivations, and characteristics (e.g., enjoyment of running).
Capacity vs Performance
- Capacity = what a person can do in a standardized/clinical setting.
- Performance = what they actually do in their everyday environment.
- A large gap between capacity and performance suggests environmental barriers or contextual issues.

The full ICF contains roughly 1,500 categories describing functioning; to be practical, condition-specific ICF “core sets” (minimum essential items) have been developed (for stroke, low back pain, hip replacement, etc.) to focus assessment and clinical reasoning.
Qualifiers (a severity scale from “no problem” to “complete problem”) are used to measure and track change in body functions, activities, and participation.
Example: an improvement in a body function qualifier (e.g., reduced muscle tone) can be linked to better walking activity and consequently to improved participation in leisure or family life.

Identify the health condition (medical diagnosis).
Use the ICF model to frame the problem: list relevant body structures/functions, activities and participation domains, plus environmental and personal factors.
Select a relevant ICF core set for the condition (minimum essential categories to assess).
Measure baseline using ICF categories and qualifiers (quantify impairments, activity limitations, participation restrictions).
Compare capacity (clinical/therapy performance) versus real-world performance to detect environmental barriers.
Formulate hypotheses that link impairments → activity limitations → participation restrictions (for example: hip instability → difficulty walking long distances → inability to participate in leisure outings).
Prioritize treatment goals using the patient’s “lived experience” (patient-centered participation goals, e.g., returning to shopping, playing sport, snorkeling).
Design interventions that target:
- body functions/structures when that is expected to improve activities and participation, and/or
- environmental modifications and facilitators when performance is limited despite preserved capacity.
Re-measure using the ICF qualifiers to evaluate change and repeat the cycle (assessment → hypothesis → intervention → re-assessment).
Integrate into evidence-based practice: combine best available evidence, clinical judgement, and the patient’s perspective/goals.

Rehabilitation objectives should translate improvements in activity into meaningful participation in the patient’s real life (the “lived experience”).
Therapists are part of the patient’s environment and can act as facilitators; true improvement often requires addressing both individual impairments and contextual/environmental barriers.
Using the ICF provides a shared language, clearer classification (standardized codes like 4500), and a structure to measure and communicate outcomes across settings and internationally.
Core sets make the ICF practical for routine clinical use by focusing on essential categories relevant to a condition.

Two women with the same medical diagnosis (incomplete spinal cord injury) but different functional outcomes — illustrates why diagnosis alone is insufficient.
“Elena” — an example of a participation goal tied to morning routines, shopping, and leisure.
“Paco” — an example linking walking activity to a leisure goal (snorkeling/diving) and using a core set focused on locomotion/walking.
