CDS®Elbow Brace Duo
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®Elbow Brace Duo functions
according to the CDS®-principle and has been
designed for the simultaneous treatment
of extension and flexion deficits of the
elbow. The brace applies a dynamic low load
prolonged stretch to stimulate growth in the
contracted tissue. The adjustable redression
range protects the tissue from overstretching
and allows for individual terminal extension
until -10°.
1.4. Application
The brace has been designed exclusively for
the orthotic treatment of the elbow joint and
for contact with intact skin.
1.5. Scope of delivery
The CDS®Elbow Brace Duo is delivered to you
ready to use in the size requested, with User
Instructions and labeling on the product.
Please check the completeness of the brace at
delivery.

of the CDS®Elbow Brace Duo with European

User Instructions
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.
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 moveable shell components can be changed and they can
be shaped.
• The hinge rods can be adapted to the shape of the extremity by bending.
• The strap lengths can be adjusted to different girths and shortened if
necessary.
2.1.1. Adjusting the brace to the arm shape by using an
orthopaedic “bending iron”
To ensure that the brace fits perfectly, the hinge rods can be adjusted to the
shape of the patient‘s arm with the aid of a bending iron.
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.

2.2. Setting the limitation
2.2.1. Setting the flexion stop
Bring the brace into extension. Turn the outer ring of the casing from “STOP”
through flexion as far as the stop. You can now set the flexion stop to the
desired number of degrees.
Then turn the outer ring back until the marker hole clicks into place at STOP.
2.2.2. Setting the extension stop
Bring the brace into flexion. Turn the outer ring of the casing from “STOP”
through “extension” as far as the stop. You can now set the extension stop to
the desired number of degrees.
Then turn the outer ring back until the marker hole clicks into place at STOP.
The extension and flexion stops should be adjusted to the progress of treatment
as the patient‘s mobility increases.

2.2.3. Setting the switchover point between flexion and extension
By moving the brace from flexion to extension and vice versa, the thrust of the
spring changes at one point. This point is called the switchover point. You can
set the switchover point in seven steps between 46° and 92°.
To set this point, you should tense the spring slightly. To adjust the switchover
point, align the spring push rod exactly between the two setting marks on the
joint rod. Swivel the brace accordingly.
The knob can now be pushed in. Turn the knob clockwise in this position until
the stop. The stop pointer shows the number of degrees for the switchover
point on the inner scale.
After you have set the desired number of degrees, turn the knob anticlockwise
until it springs back.
