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.

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.
