The medicinal improvements: • Reanimation • Neonatology• Surgery• Rehabilitation• Pharmacology
The effects of this:- Decrease in infectious diseases- Increase in chronic diseases and problems- Ageing populations

Critiques of ICIDHCritiques of ICIDH
• Classification founded on the “medical model” :– Linear causality from impairment to
handicap– Description of handicaps: insufficient – Absence of an environmental dimension
• Handicaps are described in a negative way
International conceptual evolution International conceptual evolution in the field of disabilitiesin the field of disabilities
1. Evolution of international norms- Before 1975: UN recommendations based on rehabilitation- Since 1980: a shift from rehabilitation to human rights
- International year of Persons with Disabilities (1982)- Decade of Persons with disabilities- World program actions for Persons with Disabilities- Standard rules for equal opportunities for Persons with disabilities- Convention on the Rights of Persons with Disabilities (13th of December, 2006)
2. Evolution of practices and social representation of disabilitiesa- Emergence of the Independent Living Movement (USA 1960)b- Diffusion of the model and extension of the ILM in the worldc- Development of a theory of the social model of disabilities
3. Evolution of the political representation of people with disabilities- 1993: Creation of the European Forum of persons with disability- Lobbying: UN, WHO, European Council, European Parliament:
- Nothing about us without us- Consultative status of Persons with disabilities NGOs
Models of Disability:Models of Disability:
1- Individual ModelDisability as an individual pathology
2 variants
Biomedical approach:- Prevention: intervention, prenatal diagnosis,eradication of the causal disease- Treatment: recovery by medical or technologicalMeans,- Society’s responsibility: recovery of
Handicappedperson
Functional approach:Prevention: early diagnosis and reeducation
Treatment: means of functional rehabilitation
Society’s responsibility: To improve the daily livesof persons with disabilities by means ofcompensation.
2- Social ModelDisability as a social pathology
“It is society that disables us, not our impairments.”
2 variants
Environmental approach:- The handicap is a consequence of the absence
ofenvironmental planning- Treatment: make the environment accessible- Society's responsibility: identification andelimination of the architectural, economic, socialand psychological barriers
Approach based on human rights:- The handicap results from social organizationproblems and connection problems between thesociety and the individual- Treatment: Reformulation of the political,
economic and social “rules”- Society's responsibility : Reducing theinequalities in rights and permitting, ensuringaccess to full citizen rights
Systemic Model of DisabilitySystemic Model of Disability((P.Fougeyrollas.Fougeyrollas RIPPH/SCCIDIH, Canada, 1998 , J.Sanchez CTNERHI 1989, 2002), J.Sanchez CTNERHI 1989, 2002)
An independent life in an accessible society = Environmental
+ Individual approach + Human Rights
- TRT: individual and collective
- Society's responsibilities: identifying and eliminating individual difficulties and social and psychological barriers
Interaction of ConceptsInteraction of Concepts- 1998: DCP = Explanatory model of the causes and consequences of
disease, trauma and other disruptions to a person’s integrity or development based on the anthropological model of human developpement
Patrick Fougeyrollas and Co (RIPPH, Quebec)
- 2001: ICF as the New Member in the WHO Family of international Classifications
- to provide a scientific basis for consequences of health conditions
- to establish a common language to improve communications
• to permit comparison of data across countries, health care disciplines, services
• to provide a systematic coding scheme for health information systems
A comprehensive modelA comprehensive model
• The DCP is a global approach which considers disability not as a fixed “state” but as a process which limits the person’s activities.
• In this model, the “disability” is differentiated from the “handicap” by the social variable that separates the two.
• The “handicap” is considered as a disturbance in a person’s life habits as a result of interaction between personal factors (impairment or disability) and environmental factors (obstacles). It’s a relative “situation” which varies according to the context and the environment, but which can also be modified by reducing impairment (medical care) and develops capabilities (rehabilitation) as well as adapting the environment (policies, elimination of physical obstacles).

Participation handicap Situation
The disability is not considered as a fixed state but an unsatisfying process that places the person in a situation of handicap
The HS is the partial or non-achievement of life habits resulting from the interaction between personal factors and environmental factors.
« A life habit is a daily activity or a social role promoted by the person or his socio-cultural context according to his/her characteristics (age, sex, cultural identity).

• Assessment of population health
• Impact of disability– economic– social
• Evidence-base for policy makers on different policy
interventions– responsiveness of services– efficiency – performance assessment

ICF-based toolsICF-based tools
In France: the new disability policy defined by the law n°2005-102 is partially based on the ICF concepts. The law attempts to reduce the activities limitations or the restriction of participation by:- A better accessibility- Collective and individual compensations
A multidisciplinary team assesses the compensation needs for a person with disability on the basis of:
- His or her life objectives (life project)- Defining references by the law
Using the GEVA (guide for multidimensional assessment of compensation needs of person with disability) for:
- Assessment the different dimensions of the disability of the person- Analysis compensation needs- Elaborating a compensation plan
the team proposes a personalized plan of compensation of the disability
