Height adjustment (Fig. B)
;
Before opening locking screw (4), hold the
moving part of the CPM device by grasping
the double joint (3), to prevent the part
from falling down.
• Open screw (4) and set the motion ele-
ment to the appropriate height. Ensure
that the entire upper arm lies on the
support (5). The patient should sit up
straight and be relaxed.
• Tighten screw (4).
• Now check the agreement of the axis of
motor A and the elbow joint. If required,
make a fine adjustment of the vertical
orientation, using locking pin (6).

m Caution!
Patient hazard / equipment damage—
Hold motor B for this adjustment to
secure the device.
• Hold the motion element at bracket (30).
• Now open screw (7) and set the appro-
priate angle.
• Tighten screw (7).

m Caution!
Patient hazard / equipment damage—
Hold motor B for this adjustment to
secure the device.
• Open the cam lever (8) and set the
appropriate length. Make sure that the
slider (9) is free to move at least 2 cm in
either direction. There must be enough
space for the fingers between the hand
support and motor B.
• Tighten the cam lever (8).

(Fig. E)
In most cases the setting is 0 on the scale.
In cases of a deformed forearm, the setting
may have to be changed.
• Open the locking screw (13) and per-
form the adjustment.
• Tighten the locking screw (13).
Backrest adjustment
(
(Fig. F)
Set the backrest to the foremost position
before setting the motion element to an
angle of 0° for horizontal adduction/abduc-
tion. To do so, open adjusting screw (10),
set the backrest to the foremost position
and tighten the screw.
To achieve optimal congruence between
the axis of motor A and the patient's rota-
tional axis of the elbow joint, the backrest
angle can be individually adjusted in all
other horizontal adduction/abduction
positions.
Checking the setup, fine adjustment
Please check the following before using the
CPM device on a patient:
• Check settings 1 to 6 and make sure that
the pivot of motor A agrees with the
pivot of the elbow joint, i.e., that the axis
of motor B vertically passes through the
elbow joint.
• Check that all locking screws and clamp-
ing levers are tight.
