5.2 Brace:
Picture no. 4 NF-Walker 2 brace
The brace has contact with the user’s body at the chest belt (1), hip belt (10), calf bows (7) and at
both of the user’s shoes. The brace system has a chest belt (1), securing the upper body of the user.
This belt is possible to adjust in width. The position of the user’s upper body relative to the Thorax
steel (2) can also be adjusted with the chest belt (1).
The Thorax steels (2) are suspending the fixation point for the chest belt (1) and are adjustable in
height. The Thorax steels (2) are fixed to the hip bows (4).
The Hip bows (4) are connected to a hip plate (3) and are adjustable in width. There are 2 different
sizes of the hip bows (4) to choose among in order to fit the brace to the user.
The hip plate (3) has upholstery in the front where it can come in contact with the user. At the back
there are clamps that allows adjustment of the width of the hip bows (4) and are making a steady
fixation point for the hip bows (4). The hip plate (3) is equipped with a tongue (14) that can be

The hip bows (4) are the fixation point for the hip belt (10) that is adjustable in width and depth. The
hip belt (10) will secure the user’s pelvic and will also place the user correct in the brace relative to
the hip joints (5) turning point.
Hip joints (5) are placed at the outer of the hip bows (4), carrying each of the leg bracings. Each leg is
built up of one hip joint (5), one knee joint (12) and one ankle joint (8).
The braces (11) connecting the joints allows telescopic adjustment of the length of the brace.
At each leg of the bracing, there are two rings (6 and 13). There is one at the knee joint (12) and one
at the ankle joint (8). These are the connection point for the snap hook (15) of the guide strap/elastic
that will run over the rollers at the front and back of the undercarriage. The height of these ring
clamps (6 and 13) can be adjusted by moving the rings to the next free hole.
Underneath the knee joint (12), there is a calf bow (7) for fixation of the user’s calf. The calf bows (7)
are equipped with straps, securing the user’s calf and are upholstered for comfort.
At each of the ankle joints (8), there is a foot steel (16). This foot steel is the bracket for assembling
the user’s shoe to the brace.
Shoe-clips (9) for fixation of the user’s shoes are attached to the foot steel (16). A wing nut (17) is
securing this shoe-clips (9) position. There are several different shoe-clips (9) to choose among. The
shoe-clip that fits to the shoes the user will prefer, will be assembled onto the shoe. The shoe-clip
will ensure that the shoe is held in the correct position while the user is standing in the NF-Walker 2
and provide an easy way of getting the feet out of the brace-system when the use of NF-Walker 2
comes to an end.

5.4 Guide straps/elastics
There are two guide straps/elastics connecting the brace to the undercarriage. One guide
strap/elastic is connected to the ring (6 (chapter 5.2)) near the knee joints (12 (chapter 5.2)) and is
running over the rollers at the U-tube (3 (chapter 5.1)). The other guide strap/elastic is connected to
the rings (13 (chapter 5.2)) at the ankle joints (9 (chapter 5.2)) and is running over the rollers at the
front axle (11 and 12 (chapter 5.1)). The guide straps/elastics can be slacked or tightened according
to each user’s need.
The guide straps/elastics are having a number of functions:
Stretching out the user
Guiding the walking pattern
Placing the legs under the user’s body
Ensuring weight-bearing trough the user’s body
Pulling of the undercarriage while walking
It’s possible to use either guide straps or guide elastics - or a combination of these. This will have to
be assessed for the actual user of the product.
Elastics will give the user more freedom in movement and less correcting of the gait pattern, while
the guide straps will decrease the freedom and increase the correction of the gait pattern.
Some users are using guide elastics for walking and guide straps for stretching in a standing position.
This gives the NF-Walker 2 a possibility to be both a walking aid and a dynamic standing frame.

6. Adjustment to a user
When a NF-Walker 2 is ordered to a new user, measures needs to be taken of the user in order to
decide the correct size of the product, make initial adjustments and for choosing the correct
components for the NF-Walker 2. The user’s physio/ergo-therapist is normally responsible for taking
these measures, and will, together with a consultant from Made for Movement or its
representatives, agree about the need for extra equipment.

6.1 Fitting the NF-Walker 2 to the user:
The fitting of the NF-Walker 2 will be done by the consultant from Made for Movement or its
representatives where the user is sited: school, kinder garden, at home, training center or other.
Brace: The consultant will take accurate measures of the user’s legs and adjust one leg (hip-
knee-ankle) of the brace to fit the user. If there is no difference in leg-length, the measures
are copied to the opposite brace-leg. Accurate measures of the hip width will be taken and
the distance between the hip bows will be adjusted according to this. The hip strap will be
adjusted, ensuring correct position of the user in the brace. The height of the chest belt will
be adjusted to fit the actual user. The shoes with shoe-clips assembled on to them, will be
put onto the brace.
Undercarriage: The brace will be put onto the undercarriage and the height of the column
will be adjusted. When the height is adjusted correctly, the shoes shall almost touch the
floor. The length of the undercarriage will be controlled and if needed, adjusted by
extending the front axle frame part out of the frame. A tip for correct adjustment of the
front axle, is that the ankle joint of the brace should not be allowed to touch the front axle.
This is important for the stability of the NF-Walker 2 and security of the user. Small
adjustments to the length of the damper may be done to compensate the change of angle
caused by extending the front axle. The guide straps/elastics are put on the brace and
adjusted in length so the brace is approximately in a vertical in position when connected to
the frame
Try out: The brace can now be put on to the user. Follow the description in chapter 8.5 –
8.8.
The user is now in the NF-Walker 2. The spring force of the damper can be adjusted so the
user will be given the best possible dynamic and movement. The user is now having weight
bearing in the shoes, but the pressure from the shoes against the floor may be adjusted by
increasing or decreasing the height of the column and/or the force of the damper. The
degree of stretching of the user while she/he is walking, can be adjusted by correcting the
length of the guide straps/elastics. For stretching only, without walking, guide straps can be
adjusted to a length where the user is standing in a vertical position, stretched out in the
degree that is needed for her/him.
Important: NF-Walker 2 must not be adjusted by persons not qualified to do so.

7. How to adjust
7.1 Damper
Height of damper: Loosen the two screws at the top (1), using a 4mm Umbraco key. Lift the
frame up to the wanted height and tighten both screws securely.
Stiffness of damper: Loosen, by hand, the lock nut (3) a couple of turns. If you want the
damper to be harder, turn the spring adjustment nut (2) clockwise. Anti-clockwise will give a
softer suspension. Tighten the lock nut (3) against the spring adjustment nut (2) after
adjustment.

7.2 Height of column
Loosen the screws (2) at both sides of the frame (6 screws in total). Loosen the height
setting screw (3). Adjust the height of the column (1) and tighten all of the screws securely.
Adjustment range: The column can be adjusted within a range of approximately 130mm.
Important: Make sure that the column is at least 105mm down in the main frame. Less
intervention between the main frame and column will cause instability in the undercarriage.
Important: NF-Walker 2 must not be adjusted by persons not qualified to do so.
Important: After adjusting the height of the column, please make sure that the column is not
touching the floor when the suspension is fully compressed.
Picture no. 9 Adjustment of the NF-Walker 2’s column
Important: After adjusting the height of the column, make sure that the guide strap/elastic
are rolling freely over the roller at the U-tube. If not, correct the height of the U-tube by
adjusting the height of the U-tube clamp.
