CDS®Wrist Brace Extension
User Instructions
1. Introduction
1.1. Foreword
Dynamic spring-loaded orthoses can be used
to treat joint contractures caused by both
neurological and orthopaedic conditions.
The shortening of the tissue surrounding the
joint decreases the range of motion affecting
the patient’s everyday life. Therefore, our
CDS®-concept aims to increase the range of
motion without pain by applying a constant,
appropriate low load prolonged stretch (LLPS).
1.2. Customer information
For your own safety please read through these
User Instructions carefully and accurately
before using the brace. The instructions, notes
and procedures must be read and understood
thoroughly in order to benefit from the correct
operation and use of the device. If anything
in the User Instructions is not clear, or any
instructions, operating procedures or safety
information is not fully understandable, please
contact the appropriate specialist retailer or
albrechtGmbH directly, before you use the
brace. This particularly applies to the safety
instructions.
1.3. Mode of operation
The CDS®Wrist Brace Extension functions
accordingly to the CDS®principle and has
been designed to treat an extension deficit
of the wrist. The brace applies a dynamic low
load prolonged stretch to stimulate growth
in the contracted tissue. The adjustable
redression range protects the tissue from
painful overstretching.
1.4. Application
The brace has been designed exclusively for
the orthotic treatment of the wrist joint and
for contact with intact skin.
1.5. Scope of delivery
Please check the completeness of the brace at
delivery.

1.10. Safety Instructions
The optimal effect of the brace is only
achieved when used correctly.
• The brace must only be used in the intact,
complete and mechanically undamaged
condition and with complete and intact
cushioning and walers. This must be verified
by the user before each usage.
• Opening or removing one or more belts,
as well as excessive loosening of the waler
when using the brace leads to a reduction of
the therapeutic effect of the brace and may
lead to injury.
• The brace must not be worn over open
wounds.
• The skin should be free of oils, grease, gels
or other debris, to prevent reactions with the
skin or the structure of the material.
• The orthosis should fit firmly but not
too tight, so as not to restrict the blood
circulation and adversely affect nerve and
lymph vessels. Excessive compression is
therefore to be avoided.
• Combination with other products is currently
not provided for or is to be agreed with the
manufacturer in writing.
• The brace is not intended for single use,
but is intended for multiple use by a single
person.
• The product as delivered is not sterile.
• Contact your physician immediately in the
event of an allergic reaction.
• Please note that cushioned sections can heat
up under direct sunlight. Protect the orthosis
from direct sunlight if necessary.
• Currently there is no test for flammability.
Exercise caution when using the orthosis
in the direct vicinity of open flames such as
lighters and cigarettes.
• The mechanical functions must only be
adjusted using the supplied tools in order to
avoid injuries and damage of the hinge.
• When adjusting the hinge rods to the shape
of the extermity by using an orthopaedic
bending iron, you must not bend the rods in
the area of the hinge housing or the hinge
cover as this could lead to damage or break
of the hinge.

User Instructions
1.11. Warranty
In addition to the legal warranty, we provide
a 6-month durability guarantee for the
orthosis. If properly used, this guarantees
that the orthosis will function without fault.
This excludes the padding and straps, which
are usually liable to a certain amount of
wear and tear. This kind of wear and tear
does not represent a product defect. This
manufacturer’s warranty is subject to the
condition that the orthosis is used as a medical
rehabilitation device and for no other purpose
than that described in the instructions for
use. Changes to the orthosis or the removal /
damage to the quality management seal will
invalidate the warranty.

2. Adjustment by the orthopaedic technician
2.1. Fitting to the patient
• Our CDS®braces are constructed to be adjustable.
• The position of the shell components can be changed and they can be shaped.
• The hinge rods can be adapted to the shape of the extremity by using an
orthopaedic bending iron.
• The strap lengths can be adjusted to different girths and shortened if
necessary.

User Instructions
2.1.1. Adjusting the brace to the arm shape by using an
orthopaedic “bending iron”
The brace is anatomically contoured. However, if a different shape is required,
the hinge rod can be adjusted to the shape of the patient’s forearm with the
aid of an orthopaedic bending iron. Loosen the screws on the shell components
and either move or remove them. Then adjust the hinge rod to the shape of the
extremity.
bending iron
When adjusting the hinge rod to the shape of the extremity by using an
orthopaedic bending iron, you must not bend the rod in the area of the
hinge housing or the hinge cover as this could lead to damage or break
of the hinge.

2.1.2. Setting the shell components
The shell components are moveable.
1 Loosen the screws on the shell components with the supplied tool without
unscrewing them completely.
2 Move the shell components into the desired position.
3 Tighten the screws again.

Please note that, because of its construction, the forearm leg shell in sizes
M/M, S/S and the children‘s size consists of one shell component. The shell
components can be adjusted to the shape of the extremity.

User Instructions
2.1.3. Setting the position of the redression and limitation range
The CDS®Wrist Brace Extension is constructed on the basis of a 360° hinge.
In a 360° hinge, the position of the spring housing is adjustable in relation to
the forearm hinge rod. The position of the redression and limitation range can
be thereby altered and adjusted to the patient. That way, you can adjust the
range of motion of the brace to the patient even if there are extreme motion
deficits. The position of the stops depends on the position of the redression and
limitation range.
1 Remove the pad.
2 Remove the two screws.
3 You can adjust the position of the redression range in 15° steps. Use
a goniometer to determine the desired position and adjust the hinge
accordingly.
4 Insert the screws again and tighten them.
5 Insert the pad again.

2.1.4. Setting the limitation
The limitation restricts the range of motion. Extension and the redression range
are limited by the stop screw. Before setting the extension limitation, you must
deactivate the spring tension.
1 Turn the green switch to „off”.
2 Bring the brace into flexion.
3 There are three holes on the side of the CDS®housing. The number of
degrees depends on the position of the straightening and limitation range
and can be determined with a goniometer. The stop screw is located in one
of the holes.
Then turn the stop screw with the supplied tool from the CDS®housing.
OFF
1 2 3
Before screwing it into one of the three holes, bring the brace into flexion,
so that the holes are freely accessible. Position the stop screw in the desired
position and tighten the screw. The limitation can be adjusted to the treatment
progress with increasing mobility of the patient.
Please be aware that the brace must only be used with the stop screw
positioned and tightened in one of the holes, otherwise the hinge will
be damaged.

2.1.5. Inserting the stop wedge
Flexion can be limited with the stop wedge. Before adjusting the flexion
limitation you must activate the spring tension.
Turn the green switch to „on“ and bring the brace into flexion until you feel
a slight resistance that you have to overcome in order to activate the spring
tension.
There are five positions on the side opposite the three holes. The number of
degrees depends on the position of the redression and limitation range and can
be determined with a goniometer. Insert the stop wedge in the desired position
and fix it with the supplied screw.

wrist.
It is possible for you to adjust the arm rod to the shape of the patient‘s lower
arm by using an orthopaedic bending iron.
