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®Manusan functions according to the
CDS®-principle and has been designed to treat
an flexion deficit of the fingers and wrist.
Active use trains the appendicular finger
muscles.
Passive use stimulates growth of contracted
tissue due to continuous dynamic tension.
1.4. Application
The brace must only be used for the orthotic
care of the hand.
1.5. Scope of delivery
Please check the completeness of the brace at
delivery

1.10. Safety Instructions
The optimal effect of the finger brace is only
achieved when used correctly.
• The finger 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 finger brace leads to a
reduction of the therapeutic effect of the
finger brace and may lead to injury.
• The finger 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 finger 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 brace
• 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.
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 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.

2.1.3. Adjusting the position of the redression and limitation range
The CDS®Manusan 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. 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.
That way, you can adjust the range of motion of the brace to the patient even if
there are extreme motion deficits.

2.1.8. 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.
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.
3 Then turn the stop screw with the supplied tool from the CDS®housing.
OFF

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.

2.1.9. 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”. 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.
