8Family of Who Classifications ICF belongs to the WHO family of international classifications, the best known member of which is the ICD-10 (the International Statistical Classification of Diseases and Related Health Problems). ICD-10 gives users an etiological framework for the classification, by diagnosis, of diseases, disorders and other health conditions.
9WHO FamilyBy contrast, ICF classifies functioning and disability associated with health conditions. The ICD-10 and ICF are complementary.Encouraged to use them together to create a broader and more meaningful picture of the experience of health of individuals and populations.In short, ICD-10 is mainly used to classify causes of death, but ICF classifies health.
10International Classification of Function, Disability and Health (ICF) Originally ICIDH (international Classification of Impairments, disabilities and Handicaps 1980) now ICF (International Classification of Function, disability and health 2001)Classification was conceived as means to evaluate the effectiveness of health care processes
11International Classification of Function, Disability and Health (ICF) Classification envisioned for three usesStatistics on the consequences of diseaseStatistics on use of health servicesConditions classified according to categories
12Why ICF?There is also an increased recognition among policy makers and service agencies that reductions in the incidence and severity of disability in a population can be brought about by1)enhancing the functional capacity of the person and2) by improving performance by modifying features of the social and physical environment.To analyze the impact of these different interventions, we need a way of classifying domains of areas of life as well as the environmental factors that improve performance.ICF allows us to record this information.
13THE MODEL OF ICFThe medical model views disability as a feature of the person, directly caused by disease, trauma or other health condition, which requires medical care provided in the form of individual treatment by professionals. Disability, in this model, calls for medical or other treatment or intervention, to 'correct' the problem with the individual
14The ICF ModelThe social model of disability, on the other hand, sees disability as a socially created problem and not at all an attribute of an individual. On the social model, disability demands a political response, since the problem is created by an unaccommodating physical environment brought about by attitudes and other features of the social environment.
15The ICF ModelOn their own, neither model is adequate, although both are partially valid.Disability is a complex phenomena that is both a problem at the level of a person's body, and a complex and primarily social phenomena. Disability is an interaction between features of the person and features of the overall context in which the person lives, but some aspects of disability are almost entirely internal to the person, while another aspect is almost entirely external.Summary: Both medical and social responses are appropriate to the problems associated with disability; we cannot wholly reject either kind of intervention.
16The ICF ModelA better model of disability,? synthesize what is true in the medical and social models, without making the mistake each makes in reducing the whole, complex notion of disability to one of its aspects.This model of disability is called the biopsychosocial model.ICF is based on this model, an integration of medical and social. This provides a coherent view of different perspectives of health: biological, individual and social.
17International Classification of Function, Disability and Health (ICF) The ICF was given a mandate to develop a “global common language” in the field of health and disability. The overall objective of the ICF was to develop an operational classification system on human functioning and disability thatWas applicable to every human being. (universality)Addressed multiple dimensions regarding the ‘person’ and ‘environment’ (at body, person and society levels)Was sensitive to International practices,Was based on user needsWas empirically based with field trials on applicability, reliability and utility.

20The ICFUses neutral terms to identify function at the Body function, activity and participation level rather that impairment, disability and handicap
21The ICFThe addition of the emphasis on the interaction of environmental features, both physical and social, adds an important context within which persons with disabilities can be evaluatedIncreased emphasis on function i.e. does the intervention you propose maintain or improve functionAccordingly when measuring outcomes, the effectiveness of the intervention must be seen in the context of the user’s environments

24Activity & Participation Body functions& structures
25Limitation in activity Restriction in participationImpairedbody functions& structures
28Participation is involvement in a life situation. Activity is the execution of a task or action by an individual.It represents the individual perspective of functioning.Participation is involvement in a life situation.It represents the societal perspective of functioning.
29Body structures and functions The ICF includes 4 dimensionsImpairments at a body levelActivities at the person level (formerly disability)Participation at the social level (formerly handicap)Contextual factors which list physical environment factors, such social environment factors, laws, attitudesInteraction of the environmental factors with the 3 levels result in functioning that is either positive or negative
30ActivitiesActivities are performance of person-level tasks or activities undertaken by the personDomains of activity are communication, movement, self care, interpersonal and performing the simple to complex tasks involved in major life activitiesActivities are the observable and reportable performance of actions of individuals in the context of their culture
31ParticipationParticipation is defined as “individual’s involvement in life situations in relation to health conditions, body functions and structures, activities and contextual factorsA key term is Involvement “means inclusion of the individual in life activities in the context of how and where they live”
32ParticipationThe classification of participation restriction is assessed on desired participation of the individual’s life activities within societyIt is measured by placing the observed involvement in a life activity in 1- 9 participation domains that include personal maintenance, mobility, exchange of information, social relationships, home life and assistance to others, education, work and employment, economic life, community, social and civic life
33ParticipationParticipation is qualified by the degree of restriction experiencedFor example, if mobility outside the home is moderately restricted as a function of the lack of the availability of accessible transport, then the participation code (p) would be assigned as follows: chapter 2 (participation in mobility) under the 2nd level heading (230) titled “Participation in mobility outside the home and other buildings” and restriction qualifier of moderate (2) resulting in the full code of p230.2

Within that forest we classify the dimensions of Impairments, Activities and Participation (the trees). In the Activities dimension we have several chapters or domains ranging from simple to complex activities - from sensing and recognizing to interpersonal behaviours (the trunks). Within, for example, the chapter on Interpersonal Behaviours are included activities such as general interactive skills (the branch) and included in that broad category are behaviours such as initiating social contact, responding to cues and so on (the leaves).]Item levels:1st2nd3rd4thItem levels:1st2nd3rd4thItem levels:1st2nd3rd4thItem levels:1st2nd3rd4thItem levels:1st2nd3rd4thDomains and categoriesat different levels
37THE DOMAINS OF ICFThe domains of ICF are arranged in a hierarchy (Chapter, second, third and fourth level domains), which is reflected in the coding:e.g.
38The QualifiersThe list of domains in ICF becomes a classification when qualifiers are used. Qualifiers record the presence and severity of a problem in functioning at the body, person and societal levels.
39For body function and structure, the primary qualifier The primary qualifier indicates the presence of an impairment (5 point Scale)no impairment,mild,moderate,SevereComplete
40Activity and Participation domains, 2 Qualifiers The Performance qualifier describes what an individual does in his or her current environment. Since the current environment always includes the overall societal context, performance can also be understood as "involvement in a life situation" or "the lived experience" of people in their actual context. (The 'current environment' will be understood to include assistive devices or personal assistance, whenever the individual actually uses them to perform actions or tasks.)
41Activity and Participation domains, 2 Qualifiers The Capacity qualifier describes an individual’s ability to execute a task or an action. This indicates the highest level of functioning of a person in a given domain at a given moment.
42ICF Mechanisms for Documenting Disability Status FunctioningStructuresActivityParticipation0= No Problem 1= Mild Problem 2= Moderate Problem 3= Severe Problem 4= Complete ProblemCapacity: What a person can do without assistancePerformance: What a person can actually do42
43Capacity and Performance Data Having access to both performance and capacity data enables ICF user to determine the 'gap' between capacity and performance.
44Capacity and Performance Data? If capacity is less than performance, then the person's current environment has disabled/enabled him or her to perform better:??
45Capacity And Performance: Answer the environment has facilitated performance.
46Capacity And Performance:? If capacity is greater than performance??
47Capacity And Performance: Answer Some aspect of the environment is a barrier to performance.
48Questions re Defining Capacity? Mobility (1) In your present state of health, how much difficulty do you have walking longdistances (such as a kilometer or more) without assistance?(2) How does this compare with someone, just like yourself only without your healthcondition?(Or: "…than you had before you developed your health problem or had the accident?)
49Questions defining Performance? mobility (1) In your present surroundings, how much of a problem do you actually have inwalking long distances (such as a kilometer or more)?(2) Is this problem walking made worse, or better, by your actual surroundings?(3) Is your capacity to walk long distances without assistance more or less than what you actually do in your present surroundings?
50Questions Defining Capacity: Major Life Areas (1) In your present state of health, how much difficulty do you have getting done all thework you need to do for your job, without assistance?(2) How does this compare with someone, just like yourself only without your healthcondition?(Or: "…than you had before you developed your health problem or had the accident?)
51Defining questions Re Performance: Major Life Areas (1) In your present surroundings, how much of a problem do you actually have gettingdone all the work you need to do for your job?(2) Is this problem fulfilling your job requirements made worse, or better, by the way thework environment is set up or the specially adapted tools you use?(3) Is your capacity to do your job, without assistance, more or less than what youactually do in your present surroundings?
56ActivityFor example, inability to walk and use of a wheelchair for mobility would be classified as follows: chapter 4 (Activities of moving around under the level 2 heading of walking activities (410) level of difficulty qualifier (4) and assistance qualifier (1) for a resulting code of a410.41
57Mapping ICF to an assessment forms - eligibility for benefits What, if any, movement difficulty is there? ICF – b (moderate impairment of one side of body)To what extent can you perform personal care?ICF – d (mild impairment maintaining one’s health)Do you require assistance to move from place to place inside your home/school/place of work?ICF– d (no problem moving around within buildings other than home)57

70Characteristics of a ‘Good’ Assessment of Need (AON) The ICF provides a useful framework to support AONs that are:Person centredNeeds DrivenBiopsychosocialAge appropriateMulti-disciplinaryPSI LDSIG 16/04/201070
71Suggested Framework for Assistive Technology Assessment Identify Functional LimitationIdentify Impairments that cause functional limitationWork with rehabilitation specialists to address impairment level issues.Maximize function by collaborating with rehabilitation specialist to create assistive technology solutions which take into account individual impairments.
72Joseph Pre-assessment Example (including ICF components and International Standards Organisation (ISO) 9999 (AT) products)Joseph is a 22-year-old male who received a T-12 incomplete spinal cord injury [body functions and structures (b)] from a diving accident 4 years agoAfter rehabilitation, he returned to his parents’ home and both his mother and father worked hard to meet his physical needs. During the past 3 years, however, he has had a difficult time recognising and acceptingthe changes in his lifestyle he must make [emotional functions (b1) and personal factors, identity]. As a result, Joseph frequently feels angry and depressed (b1, temperament and personality) and often prefers to be alone (d7, interpersonal interactions).At first family and friends would stop by to visit, but his withdrawal, anger and depression led to strained interactions and eventually the visits became rare occurrences (d7, e3 and e4).
73Joseph AssessmentAt Time Point 2, 3 years post-injury, Joseph learned about the existence of a wheelchair basketball team in his city that was looking for an additional player.Joseph is fortunate that he lives in a large enough city that has the facilities and resources to foster a wheelchair basketball team [e5]Joseph uses a lightweight manual wheelchair (e1,ISO 9999 class , bimanual wheel driven wheelchairs), but to play on the team required thatJoseph have an additional specialised wheelchair, that is a sport wheelchair (e1, ISO 9999 class ).His physician recommended an assessment at a local AT centre that focussed on his preferences as well as needs (b7, d4, d7, d9, personal factors), thepurpose and environments of wheelchair use (d9, e2) and desirable product features and add-ons such as special tires and a means for transporting himself and his wheelchair (ISO 9999 class 12).
74Joseph post assessment The outcome of the comprehensive assessment was the selection of a wheelchair among multiple choices that Joseph could afford, was a good match with his needs and preferences, and that performed well for him as a wheelchair basketball player [28–30].Joseph enjoyed playing on the team, and the team valued Joseph’s contribution (e3 and e4). Joseph interacted with other individuals, some who become closer friends than others (d7).The addition of Joseph affected the group identity as a whole as well as each individual (e3 and e4,personal factors). As a group they performed very well and won a regional championship.Now,almost 4 years post-injury, Joseph is finding he is less depressed and angry (b1) and greatly looks forward to being with his teammates not only on the basketball court but socially as well [d7].He is now thinking of returning to university and wants to explore additional ATs to save time and energy.
75In Summary : ICFICF describes all aspects of health in terms of health domainsICF is integration of the medical and social models – biopsychosocial approachICF is designed in a hierarchical scheme based on commonly understood principles and languageThe ICF facilitates collaboration and communication amongst system supportsICF describes situations for functioning and its restrictions and provides a framework to organise this information75
76In Summary The New Approach: ICF The ICF is an active system, it is constantly changingThe ICF understands that disability is the interaction between a person and their environmentThe ICF provides an assessment tool and a means to classify data collection using simple, common language and forms76
