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®Ankle Brace |CDS® Ankle Brace
Junior is based on the CDS®-principle and has
been designed to treat an extension deficit of
the ankle. 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 is only used for the orthotic
treatment of the ankle joint and is only
intended for contact with intact skin.
Only for short distances in the house and for
therapeutic purposes. A decision about this lies
with the physician treating the patient.
Orthoses are not suitable for
strengthening or replacing damaged
muscles!

1.8. Indications
The physician will prescribe the type of
treatment to apply based on his or her
diagnostic findings.
Generally, the use is indicated in:
• Joint contraction, among other things, as a
result of:
–vegetative state
–cerebral palsy
–genetic syndromes that are clinically
associated with tonus elevation in the
lower limb
–epilepsy
–spina bifida
–near-drowning
–surgical procedure
–burns
–stroke
–spinal cord Injury
–paralysis
–cranial brain trauma
–osteoarthritis and chronic polyarthritis
–joint replacement
• For preventing new contractures after
arthrolysis
• After conservative therapy of capsular
ligament injuries
For all other indications, the doctor must be
consulted.
1.9. Contraindications
• Bony obstruction, osteoporosis
thrombophlebitis
The brace is intended exclusively for contact
with intact skin.
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.

User Instructions

• 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.

2.1.1. Adjusting the brace by using an orthopaedic “bending iron”
The brace is anatomically contoured. However, if a different shape is required,
the hinge rods can be adjusted to the shape of the patient’s leg 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 rods to the shape of the
extremity.
Bending iron
When adjusting the hinge rods to the shape of the extremity 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. Adjusting the hinge
2.2.1. Adjusting the position of the redression and limitation
range for size L/L, L/M, L/S, M/S.
The CDS®Ankle Brace is constructed on the basis of a 360° hinge. In a 360°
hinge, the spring housing and the lower leg rod can be pivoted against each
other. The position of the redression and limitation range can be thereby altered
and adjusted to the patient.
In neurological patients it may be necessary to bring the redression range of
the CDS®Ankle Brace further into plantar flexion than the factory setting. The
position of the stops depends on the position of the redression and limitation
range.

User Instructions
www.albrechtgmbh.com 17
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.
The setting must be the same for both hinges.

2.2.2. Adjusting the position of the redression area
for sizes S/S, XS/XS, XXS
The CDS®Ankle Brace Junior in sizes S/S, XS/XS and XXS is built on the basis
of the 360° Nano Hinge. In the 360° Nano Hinge, the position of the spring
housing to the lower leg rod can be adjusted. This allows the location of the
redression area to be changed and adapted to the patient.
1 Remove the pad on the back of the hinge.
2 Loosen the central screw with the tool supplied until the hinge rod can be
lifted completely from the toothing.
3 You can adjust the position of the redression range in 10° steps. Use a
goniometer to determine the desired position and adjust the joint accord-
ingly. By changing the redression range, the extension or flexion stop can be
adjusted in 10° increments. The joint settings must be made identically on
both sides.
4 Place the joint rod back onto the gear teeth and tighten the central screw
again.
5 Put the pad back on again

2.2.3. Setting the limitation for size L/L, L/M, L/S, M/S
The limitation restricts the range of motion. All steps must be executed identically
with both hinges.
Dorsal extension and the redression range are limited by the stop screw. In a
second step, the set value can be reduced up to a maximum of 15°, enabling
infinitely variable adjustment of the redression range.
Before setting the dorsal extensions limitation, you must deactivate the spring
tension.
1 Turn the green switches on both hinges to „off”.
2 Bring the brace into plantar flexion.
3 There are three holes on the side of the CDS®housing. The number of degrees
depends on the position of the redression 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.

Before screwing it into one of the three holes, bring the brace into plantar 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.
