Summary : This figure presents the International Classification of Functioning, Disability and Health (ICF) model, specifically applied to stroke, illustrating the interrelationships between health condition, body functions, activities, participation, and contextual factors. flowchart: # Nodes : • Health Condition (rectangle): "Stroke" • Body Structures & Functions (Impairment) (rectangle): "Physiological functions of body systems (e.g. muscle power, muscle tone, gait pattern)" • Activities (Limitation) (rectangle): "Execution of functional tasks (e.g. walking, lifting and carrying objects, eating)" – Capacity (sub-rectangle): "in standardized environment" – Performance (sub-rectangle): "in actual environment" • Participation (Restriction) (rectangle): "Involvement in everyday life situations (e.g. recreation and leisure, community life)" • Environmental Factors (rectangle): "Barriers or facilitators" • Personal Factors (rectangle): "Barriers or facilitators" # Connectors : • Arrow from Health Condition to Body Structures & Functions, Activities, and Participation. • Bidirectional arrows between Body Structures & Functions and Activities. • Bidirectional arrows between Activities and Participation. • Arrows from Environmental Factors and Personal Factors to Body Structures & Functions, Activities, and Participation. # Layout : • Central top node (Health Condition) branches to three horizontally aligned nodes (Body Structures & Functions, Activities, Participation). • Activities node is subdivided into Capacity and Performance. • Environmental and Personal Factors are aligned below, with arrows pointing upward to the three main domains. # Analysis : • The diagram visually organizes the ICF framework, emphasizing that stroke (as a health condition) impacts body functions, activities, and participation, all of which are influenced by environmental and personal factors. • The bidirectional arrows highlight the dynamic and reciprocal relationships among impairments, activity limitations, and participation restrictions. • The model underscores the importance of context (environmental and personal factors) in shaping outcomes for individuals with stroke.

Summary : This flowchart illustrates the International Classification of Functioning and Health (ICF) model as applied to hemophilia, showing the relationships between disease, body structure and function, activity, participation, and influencing factors, along with associated outcome assessment instruments. flowchart: # Nodes : • Disease – Hemophilia (rectangle) • Body structure and function (rectangle) • Activity (rectangle) • Participation (rectangle) • Environmental factors (rectangle) • Personal factors (rectangle) • HJHS (rectangle, linked to Body structure and function) • X-ray (rectangle, linked to Body structure and function) • US (rectangle, linked to Body structure and function) • MRI (rectangle, linked to Body structure and function) • FISH (rectangle, linked to Activity) • HAL/PedHAL (rectangle, linked to both Activity and Participation) • HAL/PedHAL (rectangle, linked to Participation) • COPM (rectangle, linked to Participation) • SF-36 (rectangle, linked to Participation) • PROBE (rectangle, linked to Participation) • HAEMO-QoL-A (rectangle, linked to Participation) # Connectors : • Disease – Hemophilia → Body structure and function • Disease – Hemophilia → Activity • Disease – Hemophilia → Participation • Body structure and function ↔ Activity (bidirectional arrow) • Activity ↔ Participation (bidirectional arrow) • Body structure and function → Environmental factors • Body structure and function → Personal factors • HJHS, X-ray, US, MRI → Body structure and function • FISH → Activity • HAL/PedHAL → Activity and Participation • HAL/PedHAL, COPM, SF-36, PROBE, HAEMO-QoL-A → Participation # Layout : • Central vertical flow from Disease – Hemophilia down to Body structure and function, Activity, and Participation. • Body structure and function, Activity, and Participation are horizontally aligned and interconnected. • Environmental factors and Personal factors branch downward from Body structure and function. • Assessment instruments are shown as side branches to their respective domains. # Analysis : • The flowchart demonstrates a multidimensional approach to assessing hemophilia, integrating clinical, functional, and patient-reported outcomes. • Disease impacts body structure/function, activity, and participation, with feedback loops between these domains. • Multiple assessment tools are mapped to specific domains, highlighting the comprehensive evaluation strategy. • Environmental and personal factors are considered as influences on body structure and function.

A composite medical illustration and clinical photograph series demonstrating pediatric physical therapy assessments framed within the International Classification of Functioning, Disability and Health (ICF) domains. Top panel: A clinical photograph shows the 'Body Structure' level via a Straight Leg Raise (SLR) test. A child lies supine with a stabilization strap across the pelvis while a therapist elevates one leg to assess hamstring flexibility or neural tension. Bottom panel (Left - 'a'): 'Body Function' measurement using a hand-held dynamometer (microFET2) to evaluate knee extensor strength. The child is seated on a bench with legs dangling while a clinician applies resistance at the ankle. Bottom panel (Middle - 'b'): 'Activity' domain illustrated by a child performing a component of the Gross Motor Function Measure-66 (GMFM-66), involving transitional movements using a small bench for support. Bottom panel (Right - 'c'): 'Participation' level showing spontaneous motor performance. A child uses a gait trainer (walker) with a 3D accelerometer (Actiwatch) attached to the right ankle to track daily activity levels. This image illustrates the comprehensive evaluation of motor disability in pediatric populations, likely related to cerebral palsy.

| Concept | Meaning |
|---|---|
| Functioning | Umbrella term for body functions, activities, and participation (positive aspects) |
| Disability | Umbrella term for impairments, activity limitations, and participation restrictions (negative aspects) |
| Health Condition | The underlying disease, disorder, or injury (e.g., stroke, diabetes, depression) |
| Contextual Factors | Environmental + personal factors that shape the experience of disability |
| Sector | Example Application |
|---|---|
| Rehabilitation | Physical therapy, occupational therapy, speech-language pathology (e.g., ASHA uses ICF as its practice framework) |
| Education | Special education planning, assessing children with developmental disabilities |
| Mental Health | Documenting functional impact of psychiatric disorders |
| Neurology | Stroke, traumatic brain injury, multiple sclerosis, cerebral palsy |
| Musculoskeletal | Low back pain, arthritis, orthopedic surgery outcomes |
| Primary Care | Chronic disease management (diabetes, COPD, heart failure) |
| Social Policy | Disability benefits, employment support, housing accessibility |
| Insurance | Determining work capacity and disability claims |
| Public Health | Population-level surveys on disability prevalence |
| Digital Health | Integration into electronic health records (EHRs) |
| Old Medical/Biomedical Model | ICF Biopsychosocial Model | |
|---|---|---|
| Focus | Disease and impairment | Functioning and context |
| Disability defined as | A property of the person | Outcome of person-environment interaction |
| Goal | Cure or fix the impairment | Enable participation and quality of life |
| Language | Patient "suffers from" or "is afflicted by" | Person "has a health condition that affects functioning" |
