1. INTRODUCTION
Netti III and Netti III HD are comfort wheelchairs
meant for both indoor and outdoor use. It is tested
to DIN EN 12183:2014. The tests were carried out
by TÜV SÜD Product Service GmbH in Germany.
In Alu Rehab we believe that wheelchairs should be
chosen based on a thorough assessment focusing
on the needs of the user and demands from the
environment.
It is therefore important to know about the
possibilities and restrictions of the wheelchair. Netti
III is a wheelchair designed for users with the need
for comfort and relief. The combination between
the seating system and the ergonomic solutions in
the frame construction, oers many possibilities for
adaptation and adjustments and possibilities to vary
the sitting position from activity to rest using tilt and
recline functions.
Netti III is available in 2 versions:
- Netti III with seat widths from 350-500 mm
- Netti III HD for hard use and heavier loads -
with seat widths from 350 - 600 mm.
Max user weight:
- Netti III - 145 kg
- Netti III HD - 160 kg
Netti III and Netti III HD have been crash tested
at RISE ( Research Institute of Sweden) and TÜV
Rheinland according to ISO 7176-19:2008 and is
approved for being used as a seat in a car.
When mounting accessories such as power
kit etc, the weight of the accessories must be
subtracted from the max user weight.
Specications varies between countries.

1.2 CONTRA INDICATIONS
With strongly muscular spasticity and involuntary
movements we recommend the Netti Dynamic
System which oers a frame construction that
follows the movement pattern of the user.
Ignoring this advice could in unfavourable
circumstances lead to the deformation or fracture of
metal parts in the area of the back tube, the leg rests
or the arm rests.
1.3 QUALITY AND DURABILITY
The Netti III wheelchair is tested at TÜV SÜD Product
Service GmbH in Germany, following the European
Standard DIN EN 12183:2014.
As manufacturer, Alu Rehab A.S evaluates the test to
be equal to 5-6 years of normal use of the chair. The
disability of the user, the toughness of use as well as
the level of maintenance done foremost decides the
durability of the wheelchair. Thus, the durability will
vary depending on these three factors.
1.1 AREAS OF USE/INDICATIONS FOR
NETTI III AND NETTI III HD
Netti III is a multi- functional wheelchair for wheeled
transport for partially or fully immobile adolecent
and grown up persons with physical and/or mental
disabilities. It provides a means by which a disabled
person who requires the possibility to vary the
sitting position from activity to rest will prot from
using tilt and recline functions. It is designed for
users with the need for comfort and relief. The
combination between the seating system and the
ergonomic solution in the frame construction oers
many possibilities for adaptation and adjustments.
The disabilities may have multiple causes. Netti
III has an adjustable seat and back angle, thus
facilitating for the user change of position,
mobilization or posture correction (stabilization),
wherever the following functional impediments with
their multiple possible causes are present:
• limited or lacking mobility
• limited or lacking muscle power
• limited movement range
• acking or limited trunk and body stability
• hemiplegia
• rheumatic-type disorders
• craniocerebral injuries
• amputations
• other neurological or geriatric disorders.

• The user will have less discomfort during spasm as
the wheelchair supports the movement.
• After a spasm the user returns to the original
sitting position securing a good position and
pressure distribution.
• It prevents unintentional change of position.
• It prevents the user from sliding forward in the
chair and thereby getting a bad sitting position
and inadequate distribution of pressure.
• Extends the lifetime of the wheelchair.
5.4 NETTI DYNAMIC SYSTEM KIT
INTENDED USE
Netti Dynamic System is an advanced mobility
aid for users aected by dystonia. It is for users
with extensive movement patterns resulting
in strong spasms and contractions of the
user’s musculoskeletal apparatus causing joint
dislocations, involuntary movements, sliding, loss
of function and also challenging the strength of the
wheelchair.
Netti Dynamic System kit is ordered and installed by
Alu Rehab.
THE KIT CONTAINS:
• Netti Dynamic Leg supports
• Netti Dynamic seat plate
• Netti Dynamic chair back cylinder
• Netti Dynamic head support
• Frame extender
• Pelvic stabilizer - hip-belt
• Shoe shells
The patented Netti Dynamic System accommodates
the user’s extension movements letting the
wheelchair work in synergy with the user’s
movements. When accommodating the involuntary
extensions pattern, muscle tone and frequency
of involuntary movements could be reduced. The
wheelchair is dynamic and will follow the user’s
movements of both upper and lower body.

Main factors to be considered by a trained
professional:
• The user’s weight, width and height
• The character and strength of the body part
extensions and movement patterns
• Goals and improvement regarding the user’s
“Activity daily life” and health condition.
The user’s movement pattern and muscle tone may
also change over time. It is relevant to assess and
monitor the tting of the wheelchair and the power
of gas cylinders according to the development of the
user’s movement pattern and muscle tone over time.
If the gas spring is too strong, the user will not be
able to make an extension. It will be a “closed kinetic
chain”, or a static position for the user.
If the gas spring is too weak, the user will not be
lifted back to his/hers original seating position after
an extension of the upper body part.
CHAIR BACK HEIGHT
The chair back can be extended by mounting a back
extension.
NETTI DYNAMIC HEAD SUPPORT
The Netti Dynamic System is equipped with a
dynamic head support. The head support follows the
extension movement of the neck.
The depth of the head support should be adjusted
to barely touch the back of the user’s head when
sitting relaxed.
THE NETTI DYNAMIC SYSTEM CONCEPT:
What is Netti Dynamic Seating?
Netti Dynamic System is a tilt and recline wheelchair
which allows controlled Open Kinetic Chain (OK-C)
movements of the user. Static comfort wheelchairs
can be accommodated to support the user’s distal
segments. The controlled OK-C movement has an
extra impact: The distal segments can move, with a
moderate resistance.
OK-C helps to gain control of the proximal segments,
especially when the user cannot inhibit muscle
movements due to their medical condition.
Netti Dynamic System is a modular system that
can be customized and adjusted according to the
user’s need.
Typically Netti Dynamic System or its components
may be used for wheelchair users with involuntary
movements.
Before using Netti Dynamic System (NDS) or any
of its components, a seating assessment should be
carried out by a trained professional.
The therapist’s adaptations and settings of
the dynamic system must not be changed by
unskilled people.
ASSESSMENT OF DYNAMIC BACK SUPPORT GAS
CYLINDER FORCES, SUITING USER STRENGTH
AND MOVEMENT PATTERNS.
An assessment of the user is needed to nd the right
power of the cylinder.
Correct solution: The back cylinder gives full
support on a full, open kinetic chain movement
during the user’s extension pattern. When the user
starts to relax, the cylinder move the back support to
its original position.

MOUNTING, POSITIONING AND ADJUSTMENTS
OF PELVIC SUPPORTS AND SUPPORTIVE
HARNESSES
Netti Dynamic System can be equipped with several
dierent types of pelvic stabilizer and supportive
harnesses each type developed to give the user
the best stabilization support depending on the
conditions:
• Pelvic stabilizer – (included in Netti Dynamic
System)
• Upper body harnesses
• Ankle huggers
• Shoe shells
• Pelvic stabilizer, mounted to the seat plate, helps
the user to keep his position on the seat even
under full spastic extension.
Always use pelvic stabilizer / hip belt when
upper body harness is used.
See separate Mounting Description for upper body
harnesses.
Detailed descriptions are found in separate user
manuals for
• UM0116UK Netti Dynamic System, seat, back and
head support.
