The World Health Organization's International Classification of Functioning,
Disability, and Health (WHO-ICF)
Is a framework for describing and classifying health and health-related states. It
provides a standard language and conceptual basis for defining and measuring
health and disability, emphasizing the interaction between an individual's health
condition and environmental and personal factors.
What are the three main components for WHO-ICF?
- Body functions and structures
- Activities and participation
- Environmental and personal factors
Body functions and structures
This component focuses on the physiological and anatomical aspects of the
individual, including speech and language functions that are directly affected by
aphasia.
Activities and participation
This component addresses the individual's ability to perform tasks and engage in
social roles, which aphasia can significantly impact. It includes communication
activities such as speaking, writing, and social interaction.
Environmental and personal factors
This component considers the external and internal factors that influence the
individual's functioning, such as social support, access to therapy, and personal
attitudes toward the condition.
Aphasia Framework for Outcome Measurement (A-FROM) model
Provide a comprehensive and person-centered framework for managing and
measuring outcomes in individuals with aphasia.
,This model is designed to expand the focus from traditional language impairment-
based assessments to a broader consideration of the individual's life
participation, personal identity, and environment. The A-FROM model
complements the WHO-ICF framework
A-FROM model four main components?
- Impairment
- Function
- Participation
- Enviornment
A-FROM: impairment
This is similar to the "Body Functions and Structures" component of the WHO-ICF
model.
It focuses on the specific language deficits caused by aphasia, including
difficulties in speaking, understanding, reading, and writing. The model
emphasizes the importance of assessing and addressing these core language skills.
.
A-FROM: Participation
This element mirrors the "Activities and Participation" in the WHO-ICF and
focuses on the individual's engagement in life situations.
It looks at how aphasia affects the ability to participate in various roles and
activities, such as family interactions, social relationships, vocational roles, and
recreational activities.
A-FROM: Function
This component addresses the individual's ability to use language in real-life
situations, considering communication effectiveness and efficiency
Time Matters
The timing of intervention after injury can impact the effectiveness of
rehabilitation.
Early intervention is often associated with better outcomes, but there are critical
periods during which the brain is more receptive to plastic changes.
, Salience Matters
The training experience must be salient or meaningful to the individual to drive
plasticity.
Therapists should ensure that therapy tasks are relevant and engaging to the client,
enhancing motivation and participation.
Age Matters
Neuroplasticity occurs throughout the lifespan, but age-related differences exist
in the capacity for plastic changes.
While younger brains may be more malleable, older individuals can still
experience significant neuroplasticity with appropriate training.
Transference
Plasticity in response to one training experience can enhance the acquisition of
similar behaviors. Generalization
Therapists can leverage this by designing therapy activities that have broader
applicability to real-world tasks.
Interference
Plasticity in response to one experience can interfere with acquiring other
behaviors.
Therapists should be mindful of potential adverse interactions between different
therapy activities and prioritize the most critical skills for recovery.
Reduction of edema
As the swelling goes down, the compression of surrounding brain tissue is
reduced; areas that were temporarily malfunctioning due to increased intracranial
pressure begin to function more normally again.
Reperfusion
Blood flow is restored to areas of hypoperfusion (e.g., ischemic penumbrae); with
refreshed blood supply to regions surrounding necrotic tissue, surrounding brain
tissue becomes more functional.
Resolution of diaschisis
