OK-C helps to gain control of the proximal seg-
ments, especially when the user cannot inhibit
muscle movements due to their medical condi-
tion.
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 compo-
nents 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.
ASSESSMENT OF DYNAMIC BACK SUPPORT
GAS CYLINDER FORCES, SUITING USER
STRENGTH AND MOVEMENT PATTERNS
an assessment of the user is needed to find 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.
Main factors to be considered by a trained pro-
fessional:
• 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 as-
sess and monitor the fitting 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 posi-
tion 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.
MOUNTING, POSITIONING AND AD-
JUSTMENTS OF PELVIC SUPPORTS
AND SUPPORTIVE HARNESSES
Netti Dynamic system can be
equipped with several different types
of pelvic stabilizer and supportive har-
nesses 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.
see separate Mounting Description for
upper body harnesses.
