Adjusting The Device To The Patient; Patient Positioning - DJO ARTROMOT-S4 Modo De Empleo

4.2 Adjusting the device to
the patient
Note!
For the following adjustments, the
patient's arm should not yet be placed on
the forearm support of the motion ele-
ment. After you have adjusted the device
to the approximate patient measure-
ments, the patient can place his/her arm
on the armrest for a check of the setup
and for the final adjustment.
The settings are numbered 1 through 7.
For easy orientation, you will find the
same numbers on the CPM device. Al-
ways set up the CPM device in this order.
1. Height adjustment of the motion ele-
ment (rotational axis motor B – height)
2. Adjustment of the shoulder width of
the
motion element (rotational axis motors
A and B – width)
3. Adjustment of the depth of the back-
rest (rotational axis motor A – depth)
4. Upper arm length
5. Elbow positioning angle
(rotational axis motor C)
6. Forearm support
(rotational axis motor C)
7. Forearm length
Then, position the patient's arm and
perform the final adjustment.
On completion of the final adjustment,
note down the mechanical adjustment
values on the back of the patient chip
card.
Before you adjust the ARTROMOT®-S4 to
the patient, you may have to convert the
device for use on the left or right shoul-
der. (see section 6.4 "Conversion")
Before any treatment is possible, adjust the
device as follows and check the settings:

4.2.1 Patient positioning

Before you start setting up the motion ele-
ment, you must adjust the CPM device so it
is comfortable and anatomically correct for
the respective patient.
For patient positioning, the ARTROMOT®-S4
provides a number of padded, exchangeable
supports which can be attached and secured
where required.
1. Ask the patient to sit down on the seat
and to lean back.
2. Next, adjust the headrest (28). This en-
sures that the patient is sitting in the
middle of the chair: The height is adjusted
by means of the height adjustment unit
of the motion element (8); the depth is
adjusted by changing the position of the
guide rods (29), the ball joint of the head-
rest can be used for fine adjustment.
3. Adjust the width (6) and height (5) of the
armrest for the healthy arm to a posi-
tion where the patient sits up straight
(shoulders at the same height) and
comfortable.
4.2.2 Adjusting the motion
element
Standard settings such as for a normal
lateral adduction/abduction movement
combined with anteversion/retroversion
and internal/external rotation.
