Contextual Intervention Planning — Incorporate environmental, activity-related, and contextual factors into intervention planning and delivery. - National Physical Therapy Examination NPTE

SECTION 1

Historical Context & Motivation

For much of the twentieth century, physical therapy interventions were designed primarily around impairment-level findings — restricted range of motion, diminished strength, or altered muscle tone — with relatively little attention to where and how patients actually lived. Treatment occurred in clinical environments that bore little resemblance to the homes, workplaces, or community settings where patients needed to function. The concept of contextual intervention planning emerged gradually as researchers and clinicians recognized that gains achieved on a treatment mat often failed to transfer to everyday tasks like navigating a gravel driveway, cooking in a narrow kitchen, or returning to a physically demanding occupation.

This evolution reflected a broader paradigm shift across rehabilitation sciences — from a purely biomedical, body-structure-focused model to one that embraces person-environment interaction as the cornerstone of meaningful recovery. Understanding this historical arc is essential for NPTE preparation, because examination items frequently test whether candidates can identify the most appropriate intervention given a specific environmental, social, or activity context.

1980 • WHO ICIDH Framework

The World Health Organization publishes the International Classification of Impairments, Disabilities, and Handicaps (ICIDH), introducing a linear model that distinguished body-level impairments from functional disabilities and societal handicaps. Although limited, this was the first major international framework acknowledging contextual dimensions of health.

1991 • Nagi Disablement Model Adopted by APTA

The American Physical Therapy Association formally embraces Saad Nagi's disablement model, which delineates pathology, impairment, functional limitation, and disability — explicitly recognizing that disability arises at the intersection of the individual and their environment.

2001 • ICF Published by WHO

The International Classification of Functioning, Disability and Health (ICF) replaces the ICIDH, embedding environmental factors and personal factors as co-equal determinants of activity and participation. This framework becomes the conceptual backbone of contextual intervention planning worldwide.

2008 • APTA Guide to Physical Therapist Practice 2.0

The updated Guide aligns physical therapy practice with the ICF, mandating that examination and intervention address body functions and structures, activities, participation, and contextual factors — codifying contextual intervention planning within entry-level education.

2014–Present • NPTE Blueprint Integration

The Federation of State Boards of Physical Therapy (FSBPT) incorporates context-sensitive decision-making throughout the NPTE content outline, including items on environmental modification, activity-specific training, and community reintegration across all body system domains.

The central question this history addresses is deceptively simple: How do we ensure that the interventions we select and deliver actually work in the patient's real life? Answering that question requires clinicians to systematically incorporate environmental barriers, task demands, and personal contextual factors into every stage of care — from initial evaluation through discharge planning.

SECTION 2

Core Principles & Definitions

Contextual intervention planning rests on several foundational ideas drawn from the International Classification of Functioning, Disability and Health (ICF) and ecological models of motor behavior. At its core, the approach insists that a patient's functional performance is not determined solely by their body structures and functions but is instead the product of dynamic interactions among the individual, the task, and the environment. To apply this principle clinically, physical therapists must understand the key categories of contextual factors and how each modifies intervention selection, intensity, and setting.

Environmental Factors

Physical, social, and attitudinal features of the environment that act as facilitators or barriers to function. Examples include terrain, lighting, stair dimensions, caregiver availability, workplace ergonomics, and community accessibility.

Activity-Related Factors

The specific task demands that a patient must meet, including biomechanical requirements, cognitive load, temporal pacing, and safety constraints. A sit-to-stand transfer in a hospital bed differs markedly from rising off a low toilet in a patient's 1950s ranch home.

Personal Contextual Factors

Individual characteristics not part of a health condition — age, sex, coping style, education, cultural background, motivation, and prior movement experience. These factors shape how a patient interacts with their environment and engages in therapy.

Task-Environment-Individual Triad

Derived from dynamic systems theory and Newell's constraints model, this triad holds that movement emerges from the interaction of organismic (individual), task, and environmental constraints. Effective interventions manipulate one or more of these three nodes.

Participation-Centered Outcome

The ultimate goal of contextual planning is improved participation — the patient's ability to fulfill life roles (parent, worker, athlete, community member) in their actual settings, not merely to demonstrate isolated movements in a clinic.

✦

KEY TAKEAWAY

Think of contextual intervention planning like training a pilot in a flight simulator rather than a classroom. A pilot who only reads textbooks about aerodynamics may understand lift and drag, but without practicing in realistic turbulence, crosswind, and instrument-failure scenarios, they cannot safely fly a real aircraft. Similarly, a patient who can perform a perfect squat in the clinic may still fall on the icy sidewalk outside their apartment if their therapy never incorporated variable surfaces, footwear, and environmental distractions. The context is the intervention.

SECTION 3

Visual Explanation — The ICF Contextual Model

The following diagram illustrates how the ICF framework structures the relationship among a patient's health condition, body functions and structures, activities, participation, and the contextual factors that modulate every interaction. Notice that environmental and personal factors do not sit at the bottom of a hierarchy — they are bidirectional modulators that can facilitate or constrain each domain.

The ICF model positions environmental factors and personal factors as bidirectional modulators (dashed arrows) of body functions, activities, and participation. The contextual intervention plan at the bottom synthesizes all domains into actionable clinical decisions.

As the diagram shows, a health condition such as a stroke does not dictate participation outcomes in isolation. A patient with moderate hemiparesis may achieve full community reintegration if environmental facilitators — accessible home modifications, supportive family, available public transportation — are in place. Conversely, a patient with mild impairments may experience severe participation restrictions if environmental barriers (second-floor apartment, no elevator, limited social support) remain unaddressed. The physical therapist's role is to identify and manipulate these contextual variables alongside traditional impairment-level interventions.

SECTION 4

How Contextual Factors Shape Intervention Design

Rather than relying on mathematical formulas, contextual intervention planning follows a structured clinical reasoning framework. The physical therapist must systematically evaluate three constraint categories — individual (organismic) constraints, task constraints, and environmental constraints — and determine which are modifiable and which require compensatory strategies. This reasoning draws on Newell's constraints model, a conceptual framework widely referenced in motor learning and motor control literature.

Newell's Constraints Model Applied to Intervention

Karl Newell proposed that movement patterns are emergent properties arising from the confluence of three interacting constraint categories. In clinical application, the physical therapist assesses each category to determine the optimal intervention approach. Organismic constraints include structural (height, limb length, body mass) and functional (strength, ROM, cognition, motivation) characteristics of the individual. Task constraints encompass the rules, goals, and implements of the activity — for example, the weight of a grocery bag, the speed required to cross a street before the signal changes, or the fine motor precision needed to button a shirt. Environmental constraints are the physical and social surroundings in which the task occurs — surface type, ambient lighting, temperature, noise level, presence of other people, and regulatory requirements of the space.

Newell's constraints model represented as three overlapping circles. The emergent movement pattern at the center arises from the simultaneous interaction of individual, task, and environmental constraints. The clinician can intervene at any node or at the intersection.

Clinical Reasoning Steps

Identify the target activity. Determine the specific meaningful task the patient needs or wants to perform — e.g., returning to work as a warehouse loader, walking their child to school, or bathing independently.
Analyze task demands. Break the activity into its biomechanical, cognitive, and perceptual components. Identify critical force requirements, balance demands, and temporal constraints.
Map environmental context. Gather data on the physical setting (dimensions, surfaces, fixtures), social setting (caregiver availability, community resources), and institutional setting (workplace policies, school accommodations).
Assess individual constraints. Evaluate impairments, functional limitations, personal factors (motivation, learning style, cultural preferences), and comorbidities that influence treatment tolerance.
Design the intervention. Select techniques that address modifiable constraints — remediate impairments where possible, modify the environment where necessary, adapt the task when both are insufficient, and train compensatory strategies as a last resort.

💡

NPTE TIP

On the NPTE, many intervention items present a clinical scenario and ask you to select the most appropriate next step. The best answer often incorporates a contextual variable — such as adapting the exercise to the patient's home layout, adjusting intensity for an outdoor surface, or involving a caregiver. The purely impairment-focused answer may be clinically sound but is not the best answer if the stem provides contextual information.

SECTION 5

Detailed Breakdown — Categories of Contextual Factors

To plan interventions that genuinely transfer to real life, the physical therapist must systematically consider multiple layers of contextual information. The ICF classifies environmental factors into five chapters and acknowledges personal factors as an unlisted but essential category. For NPTE preparation, it is useful to organize these factors into a clinical taxonomy that directly informs intervention decisions.

Category	Examples	Clinical Intervention Implication
Physical Environment	Stair dimensions, door widths, floor surfaces, bathroom fixtures, outdoor terrain, climate	Train transfers on surfaces matching the home; recommend grab bars or ramps; incorporate outdoor ambulation on varied terrain during therapy
Social Environment	Caregiver availability and skill, family dynamics, cultural expectations of disability, peer support	Include caregiver training in session; design a home exercise program that fits family routines; address cultural beliefs about recovery
Products & Technology	Assistive devices, orthotics, wheelchair specifications, vehicle modifications, smartphone apps for exercise compliance	Match device to environment (e.g., rollator vs. standard walker on carpet); train patient in device use within actual setting; consider cost and insurance coverage
Attitudes & Policies	Employer accommodation willingness, ADA compliance, school policies, community stigma, insurance reimbursement	Advocate for workplace modifications; document functional gains in participation language for payer justification; coordinate with school team for pediatric patients
Activity-Related	Occupational demands (lifting, standing, repetition), recreational tasks, ADL/IADL complexity, driving requirements	Simulate work tasks using job-specific objects; grade ADL training from simple to complex environments; incorporate dual-task training for community mobility
Personal Factors	Age, sex, race, coping style, self-efficacy, health literacy, prior fitness level, psychological status	Tailor communication to health literacy level; select motivational strategies aligned with coping style; adjust exercise intensity for age and fitness baseline

Contextual Factor Categories with Clinical Implications for Intervention Planning

An important clinical principle is the distinction between facilitators and barriers. The same factor can function as either depending on the patient's specific profile. For instance, a supportive spouse is typically a facilitator, but if the spouse becomes overprotective and performs tasks the patient could do independently, the social environment becomes a barrier to functional independence. The physical therapist must evaluate each contextual factor dynamically rather than assuming a universal positive or negative valence.

SECTION 6

Worked Example — Contextual Intervention Planning for a Post-Stroke Patient

Consider the following clinical scenario, representative of the type of reasoning tested on the NPTE. A 68-year-old retired postal worker, Mr. Hernandez, is 4 weeks post right MCA stroke with left hemiparesis. He lives alone in a two-story home with a bedroom and only bathroom upstairs. He has 12 steps with a right-side railing. His daughter visits twice weekly but lives 30 minutes away. He was previously independent in all ADLs and walked his neighborhood daily. His goal is to return home and resume independent living.

Contextual Intervention Plan for Mr. Hernandez

1
Step 1 — Identify Target Activities

Based on the patient interview and functional assessment, the priority activities are: (a) ascending and descending 12 stairs to access the bedroom and bathroom, (b) independent toileting and bathing, (c) meal preparation in a small kitchen, and (d) outdoor ambulation on neighborhood sidewalks. These activities are anchored to his participation goal of living independently at home.

Priority: Stair negotiation, bathroom ADLs, kitchen IADLs, community ambulation
2
Step 2 — Analyze Task Demands

Stair ascent requires concentric hip and knee extension strength, adequate ankle dorsiflexion for foot clearance, single-limb stance balance on each step, and the ability to grip a railing — which in his home is on the right (his unaffected side, fortunately). Bathroom tasks require standing balance for toileting and the ability to step over a tub wall (measured at 15 inches). Kitchen tasks involve reaching, carrying, and standing tolerance for 15−20 minutes. Community walking requires navigating uneven sidewalks with curb cuts and crossing intersections within timed signals (approximately 1.2 m/s walking speed minimum for safe crossing).

Critical task demands: SLS balance, grip strength, tub transfer, walking speed ≥ 1.2 m/s
3
Step 3 — Map Environmental Context

A home evaluation (or detailed interview with daughter if home visit is not feasible) reveals: 12 steps with right-side railing (facilitator — matches unaffected side), standard bathtub-shower combination without grab bars or shower seat (barrier), kitchen with adequate space and microwave at counter level (facilitator), neighborhood sidewalks with some cracking and one busy intersection (barrier — requires adequate walking speed). Social context: daughter available twice weekly (moderate facilitator), patient lives alone otherwise (barrier for emergencies). Personal factors: high motivation, college-educated (facilitator for health literacy), mild depression since stroke (barrier to exercise adherence).

Key barriers: no bathroom safety equipment, limited social support, depressive symptoms, uneven sidewalks
4
Step 4 — Design Context-Specific Interventions

For stair training: practice on clinic stairs with right-side railing, progressing from step-to pattern to step-over-step as strength improves; simulate the exact step count (12) to build endurance and confidence. For bathroom safety: recommend installation of grab bars beside the toilet and in the tub, a tub transfer bench, and a hand-held showerhead; train tub transfers in the clinic using a mock-up of comparable dimensions (15-inch wall height). For kitchen tasks: standing tolerance training with progressive duration at a counter-height surface; reaching exercises simulating cabinet access; carry training with weighted bags. For community ambulation: overground walking on varied surfaces (tile, carpet, outdoor pavement) with dual-task challenges (talking, carrying objects); gait speed training targeting ≥ 1.2 m/s for safe intersection crossing. For depression: integrate enjoyable activities into the program, refer to psychologist for screening, involve daughter in goal-setting sessions to strengthen social support.

Plan addresses modifiable barriers (equipment, task simulation, speed training, social support) while leveraging facilitators (motivation, right-side railing, health literacy)
5
Step 5 — Plan Discharge with Contextual Follow-Through

Discharge planning begins at evaluation. The home exercise program is designed for his actual living space — stair repetitions on his own stairs as a strengthening activity, standing kitchen exercises that double as meal prep practice, and a daily neighborhood walk route with identified rest points (bench at the corner, mailbox at the halfway mark). Daughter receives caregiver education on fall risk monitoring and emergency response. A follow-up home visit or telehealth check-in is scheduled for 1 week post-discharge to assess carryover and troubleshoot unexpected barriers.

Discharge plan integrates HEP into actual environment, includes caregiver training, and schedules contextual follow-up

SECTION 7

Strengths, Limitations, and Clinical Considerations

Contextual intervention planning offers substantial advantages over impairment-only approaches, but it also introduces practical challenges that clinicians must navigate. The following comparison outlines the key strengths and limitations recognized in the rehabilitation literature.

Strengths	Limitations
Improves ecological validity — gains in clinic transfer more reliably to real-world settings	Requires more time for environmental assessment (home visits, detailed interviews, community evaluations)
Enhances patient motivation by linking interventions directly to personally meaningful activities and goals	Environmental modifications may be costly and not covered by insurance; socioeconomic disparities can limit implementation
Reduces fall risk and hospital readmissions through proactive barrier identification and mitigation	Clinician must possess strong clinical reasoning and assessment skills beyond traditional impairment testing
Supports patient-centered care and shared decision-making, aligning with contemporary ethical standards	Contextual information may be incomplete if home visits are not feasible (e.g., acute care setting, telehealth constraints)
Aligns directly with ICF framework and current APTA standards of practice, strengthening documentation and payer justification	Lack of standardized assessment tools for some contextual domains (especially personal factors) can make documentation inconsistent

Strengths vs. Limitations of Contextual Intervention Planning

✦

KEY TAKEAWAY

The limitations of contextual intervention planning are predominantly logistical, not conceptual. The evidence consistently supports its superiority over impairment-only approaches for promoting lasting functional gains. When the NPTE presents a scenario with contextual information, the exam is testing whether you recognize that an excellent biomechanical intervention can still be the wrong choice if it ignores the patient's reality. Even in settings where home visits are impossible, detailed patient and caregiver interviews, photographs, and telehealth walk-throughs can approximate the contextual assessment.

SECTION 8

Connection to Advanced Theory — From Contextual Planning to Ecological Practice

Contextual intervention planning, as covered on the NPTE, represents the foundational level of a broader clinical paradigm often called ecological practice or participation-based practice. As you advance into clinical residencies and specialized practice, these concepts deepen considerably. Understanding the relationship between entry-level contextual planning and advanced ecological models will help you appreciate where the NPTE content sits within the larger professional trajectory.

Dimension	NPTE-Level Contextual Planning	Advanced Ecological Practice
Assessment Scope	Identifies key environmental and personal barriers/facilitators using interview and standardized tools (e.g., Craig Hospital Inventory of Environmental Factors)	Comprehensive ecological assessment across multiple environments over time; participatory mapping with patient, family, community; longitudinal monitoring
Intervention Setting	Simulates the real environment within the clinic setting; may include one or two home visits	Majority of treatment occurs in the actual environment (home, workplace, community); in-situ practice is the default
Interdisciplinary Role	Coordinates with OT, social work, and case management for discharge planning	Leads interprofessional teams in community reintegration programs; collaborates with urban planners, vocational specialists, and policy advocates
Outcome Focus	Function and activity-level outcomes (e.g., Timed Up and Go, 6-Minute Walk Test, FIM scores)	Participation-level outcomes (e.g., COPM, community participation indicators, quality of life indices, return-to-work rates)
Theoretical Depth	ICF model, Newell's constraints model, basic motor learning principles (task specificity, variable practice)	Ecological psychology (Gibson's affordances), complexity theory, self-determination theory, occupational science frameworks

NPTE-Level vs. Advanced Ecological Practice

For current NPTE preparation, focus on mastering the entry-level competencies: systematic identification of environmental and personal contextual factors, integration of these factors into goal-setting and intervention selection, and appropriate use of task-specific training in context-relevant conditions. The advanced concepts — Gibson's affordance theory, complexity science, and participatory action research methodologies — represent the frontier of rehabilitation science that you may encounter in doctoral projects, residencies, and specialized fellowship training.

SECTION 9

Practice Problems

Question 1: CONCEPTUAL

According to the ICF framework, a patient's inability to return to work as a construction laborer after a lumbar fusion, despite achieving full spinal ROM and adequate strength in the clinic, is best classified as a deficit at which level?

Show answer

This scenario describes a deficit at the participation level. The patient has resolved impairments (ROM and strength are adequate) and can likely perform many activities in isolation, but the specific contextual demands of his occupation — heavy lifting, prolonged standing, outdoor conditions, and employer return-to-work policies — create barriers to fulfilling his worker role. Contextual factors (occupational task demands, employer attitudes, workplace layout) are the primary drivers of this participation restriction. The physical therapist should design work-conditioning interventions that simulate actual job demands rather than continuing to target impairments that have already resolved.

Question 2: BASIC APPLICATION

A 74-year-old woman with bilateral knee osteoarthritis uses a front-wheeled walker on the level linoleum floors of her assisted living facility without difficulty. She now wants to visit her daughter's home, which has thick carpet throughout and a 4-inch step at the front entrance with no railing. Identify two environmental barriers and describe one intervention modification for each.

Show answer

The two environmental barriers are: (1) thick carpet, which increases rolling resistance for the front-wheeled walker and destabilizes balance; and (2) the 4-inch step without a railing, which creates a fall risk during entry and exit. For the carpet barrier, the therapist could train the patient on a carpeted surface in the clinic, adjust walker wheel size or type (larger wheels roll more easily on carpet), or recommend a rollator with larger wheels for visits. For the step barrier, the therapist could practice step negotiation in therapy using a comparable step height without railing support, and recommend the daughter install a temporary portable railing or ramp. Both interventions transform the barrier from an insurmountable obstacle into a manageable challenge through environmental modification and task-specific training.

Question 3: INTERMEDIATE

A 45-year-old patient 6 months after traumatic brain injury demonstrates adequate balance and gait in the quiet, well-lit physical therapy gym (Berg Balance Scale = 48/56, gait speed = 1.0 m/s), but reports frequent near-falls at the grocery store. Using Newell's constraints model, analyze which constraint category is most likely responsible for the performance discrepancy and design an appropriate intervention progression.

Show answer

The performance discrepancy between the controlled clinic and the grocery store most likely arises from environmental constraints interacting with residual individual constraints (likely impaired attention and sensory integration after TBI). The grocery store introduces visual complexity (bright fluorescent lighting, moving shoppers, colorful product displays), auditory distraction (announcements, cart noise), and navigation demands (turning corners, reaching for items while standing) that overwhelm the patient's attentional capacity. Using Newell's model, the intervention should progressively increase environmental complexity while maintaining the task. A sample progression: (1) gait training in the clinic with added auditory distractions (background music, conversation); (2) dual-task walking with cognitive loading (counting backwards, naming items from a list); (3) practice walking in a busy hospital hallway with other people and varied lighting; (4) community outing to a store during a quiet time with PT supervision; (5) independent store visit during normal hours with PT observation from a distance. This systematically escalates the environmental constraints until they match the real-world context.

Question 4: APPLIED

A 58-year-old female patient is being discharged from inpatient rehabilitation following a right total knee arthroplasty. She lives alone in a second-floor apartment accessed by 14 exterior stairs with bilateral railings. Her car is parked in a covered lot 100 meters from the building entrance on a concrete surface with a 3% grade. She works as an elementary school teacher and must be able to stand for 3-hour blocks, walk between classrooms on tile floors, and sit in a standard chair at child-height tables. Her insurance covers 6 additional outpatient PT visits. Design a contextual intervention plan that prioritizes goals and allocates visits to maximize her functional outcomes.

Show answer

With only 6 outpatient visits, strategic allocation is critical. Visits 1−2 should focus on stair negotiation (14 steps, bilateral rail technique for safety), progressing from step-to to reciprocal pattern, and a home exercise program targeting knee ROM (goal ≥ 110° flexion for sit-to-stand from child-height chair), quadriceps strengthening, and gait endurance. Visit 3 should address community ambulation: practice walking 100+ meters on a slight grade to simulate the car park, including car transfers. Introduce standing tolerance training at a counter surface for progressive durations (30, 60, 90 minutes). Visits 4−5 should simulate work demands: walking on tile (clinic hallway), sit-to-stand transitions from a low chair (simulate child-height table), and standing for extended periods with intermittent walking. Include sit-to-stand from a standard toilet height and from the lower child chairs. Visit 6 should be a comprehensive review and discharge with an advanced HEP tailored to her apartment and school. Environmental recommendations should include a temporary elevated toilet seat for the first 2 weeks, anti-fatigue mats at the classroom standing station, and a graduated return-to-work schedule coordinated with her principal. This plan prioritizes the most participation-critical tasks first and leverages each visit for maximum contextual relevance.

Question 5: CRITICAL THINKING

Two patients — Patient A and Patient B — both have identical impairment profiles following ACL reconstruction: full ROM, 85% quadriceps strength symmetry, and hop test limb symmetry index of 90%. Patient A is a 22-year-old competitive soccer player whose team practices on natural grass in a rainy Pacific Northwest climate. Patient B is a 22-year-old recreational jogger who runs 3 miles on a paved greenway trail in a temperate Southeastern climate. Argue how contextual factors would lead to fundamentally different return-to-activity interventions despite identical impairment-level outcomes. What are the ethical implications if contextual factors are ignored?

Show answer

Despite identical impairment profiles, the contextual demands diverge dramatically. Patient A requires a return-to-sport program that includes reactive agility drills on natural grass (which is softer and less predictable than clinic flooring), cutting and pivoting maneuvers on wet surfaces (the Pacific Northwest climate means frequent rain during practices), contact confidence drills simulating tackles, and sport-specific endurance under competitive pressure. Environmental constraints — wet grass, cleats, opponent contact, game-speed decision-making — dramatically increase the demand on the ACL graft compared to controlled testing. Patient B requires a progressive running program on a paved surface with gradual mileage increases, which is a primarily linear, predictable activity with minimal lateral force. The contextual demands are substantially lower — no cutting, no contact, consistent surface. Ethically, treating both patients identically based solely on impairment scores would violate the principle of beneficence because Patient A would be cleared for a high-risk environment without adequate preparation, significantly increasing re-injury probability. It would also violate the principle of justice, as Patient A's greater contextual risk is not being addressed equitably. The physical therapist has an ethical obligation to ensure that return-to-activity criteria incorporate the specific demands of the patient's real-world participation context, not merely normalized test scores.

SUMMARY

Lesson Summary

Summary

Contextual intervention planning is a clinical reasoning approach that integrates environmental factors (physical setting, social support, products and technology, attitudes and policies), activity-related demands (biomechanical requirements, cognitive load, temporal constraints), and personal contextual factors (age, motivation, culture, coping style) into every phase of physical therapy care. Rooted in the ICF framework and Newell's constraints model, this approach recognizes that functional movement is an emergent property of the interaction among individual, task, and environmental constraints — not a fixed attribute of the patient alone.

For the NPTE, remember that the best intervention answer in a contextual scenario will address modifiable barriers and leverage available facilitators, incorporate task-specific training that simulates real-world demands, and plan for discharge in the patient's actual environment. The clinical reasoning process — identify target activities, analyze task demands, map the environment, assess individual constraints, and design context-specific interventions — provides a systematic framework applicable across all patient populations and practice settings.
