Low Technology:
- Defined as being a simplistic
and/or inexpensive item which
assists individuals in
participating within their
preferred occupations.

Examples:
- Communication Boards
- Pencil Grips
- Universal Cuffs

High Technology:
- Defined as being an expensive
item or tool which is either
difficult to make or attain.

Examples:

The handcycle is a piece of high technology as it is a specialized bicycle. It allows those effected with lower body paralysis or weakness. It enables individuals to pedal and steer with their upper extremities and in a similar mechanism.

The Scalacombi is a piece of high technology and it enables caretakers to safely transfer their client or family member down the stairs. It is a modified electric wheelchair which has three rows of wheels. The first row is utilized when one is using the wheelchair on a level surface. The middle row lowers itself onto the stair below and the back row elevates and moves forward onto the step below following the middle row.

The Overlander 4ZS is a piece of high technology which is essentially the combination of a quad and an electric wheelchair. It allows those who are wheelchair bound to explore the wilderness and terrains any normal wheelchair couldn't possibly handle.

Occupational Therapists have many duties and responsibilities when it comes to providing seating and wheel mobility (SWM) services. These services are in place in order to ensure the comfortability and functionality of the individual who utilizes them. The settings must appropriately fit that individual's client factors as well as their environmental and context factors. The HAAT model is often utilized within wheelchair selection and modification in order to increase an individual's occupational performance.

Services Include:
- Evaluations to determine an
individual's skills, mobility and
preferred occupations.
- Address client's needs, goals,
interests, supports, and
barriers which effect their
functionality.
- Assess and recommend
possible equipment,
modifications, and strategies
which appropriately fit the
client's skills and goals.
- Measure client's success with
the piece of equipment which
is established through their
overall health and life
satisfaction.

Stands for:
- Human Activity Assistive
Technology Model

Components:
Human:
- The client factors an individual         has in terms of  physical and
cognitive capabilities.
Activity:
- Occupations an individual
takes part in which may
include ADLs or IADLs.
Assistive Technology:
- The piece of assistive
technology which is selected
for utilization. This can include
low or high technology.
Context:
- The environment or resources
an individual has at disposal
when they are participating
within occupations. These are
in reference to physical, social,
cultural, and institutional
factors.

Explanation of the HAAT Model:
- The HAAT Model is utilized in
order to make practitioners
more aware of how all of the
components intertwine and
overall effect an individual's
occupational performance.
Each component must work
with one another and fit like a
puzzle. If not an individual's
occupation performance will
ultimately decrease.

Example of the HAAT Model :
Human:
- Nicole who has cerebral palsy
with limited functionality in all
four limbs. Intact cognition
with the ability to speak.
Although minimal function in
UE prefers to use RUE to
perform tasks
Activity:
- Digital communication
Assitive Technology:
- Voice command headset
Context:
- School environment with peers
Result:
- Because Nicole enjoys using
her RUE as much as possible
a headset may not be the best
piece of AT for her. The use of
a headset will ultimately
decrease her functionality and
motivation. This is especially
true within the context of a
school as she may feel more
ostracized by her peers.
Instead Nicole would benefit
from an adapted keyboard
which would allow her to use
her RUE proficiently and in a
manner which wouldn't
sacrifice her self-esteem.

The TacTee is a high end rendition of the low technology piece of an universal cuff. Because of the specialization within the TacTee it is considered to be a piece of high technology. The TacTee has strong magnets and individualized cuffs with special attachments including a fork, spoon, and knife. There is also a universal cuff option that allows for the utilization of things such as a toothbrush.

The portable transfer sling is considered to be a piece of low technology as it is a fairly simple design however, holds an important purpose. Although merely being cloth and handles in its entirety this piece allows for easier transfers within tight confinements. This is due to its number of handles and mobility
