† Horizontal adduction/
abduction (Fig. A)
It is the purpose of the adjustment proce-
dures to accommodate the patient in the
most comfortable position possible.
• Press on the indexing knob (12) and
make sure that it locks into place after
the adjustment.
Œ Height adjustment (Fig. B)
Before opening locking screw (14), hold the
moving part of the CPM device by grasping
the holding tube for the length adjustment
(17), to prevent the part from falling down.
• Adjust the height so that the axis of
motor A is level with the pivot of the
shoulder joint (see illustration on page
56). The pivot of motor A and the pivot
of the shoulder joint must be on the
same level.
• Tighten the locking screw.
Å Upper arm length (Fig. C)
The device for adjustment of the upper
arm length is self-locking.
During adjustment, slightly lift motor B
and ensure that the insertion tube does
not wedge in the holding tube.
• Loosen clamping lever (18) and slightly
lift the motor during adjustment.
• Tighten the clamping lever.
è Elbow angle (Fig. D)
In most cases an angle of 90° to 60° is
adjusted for elbow flexion.
• Loosen locking screw (20). To facilitate
the adjustment, slightly lift motor B.
• Complete the adjustment and tighten
the locking screw.
Note!
If the elbow angle is changed to a
flexion value of greater than or less
than 90°, the setting for the upper arm
length will have to be changed, too.
ì Forearm length (Fig. E)
• Loosen clamping lever (26) and pull out
the handle until the forearm can easily
be accommodated between elbow sup-
port and handle.
• Tighten the clamping lever.
Note!
The armrest inclination can be adjusted
until optimally suited to the arm.
To do so, loosen the locking screw (28)
below the armrest. Adjust the inclina-
tion and tighten the locking screw.
Checking the setup,
fine adjustment
• Place the patient's arm on the armrest.
• Check adjustments 1 through 5 to ensure
that
– the pivot of motor A and the pivot of
the shoulder joint are on the same
level
– the axis of motor B, the center of
the elbow joint and the center of the
shoulder joint form a straight line.
To adapt the armrest even better
to the patient, you can also adjust
its height and inclination. To do so,
loosen the locking screw (28) below
the armrest.
• Check that all locking screws are tight-
ened and all clamping levers properly
closed.
