4. Ensure seat is in inclined position (front of seat tilted upward
approximately 15°). If not, lift up on seat until it locks into the prop-
er position.
5. Seat patient. Move patient anteriorly or posteriorly to approximate
longitudinal spinal axis with the fixed axis of the Back Ex/Flex
Attachment.
6. Position footrest so that it will not interfere with patient positioning.
7. Adjust patient axis height by pumping seat up or down using Seat
Height Foot Pedal. Align the fixed axis of the machine with the sub-
ject’s anterior superior ileac spines (ASIS’s). Half-strokes move seat
up. Full strokes held down lower seat. Note the value indicated on
the seat height scale so that it may be entered under subject settings.
8. Adjust Sacral Pad to provide desired firmness or maximum patient
comfort. To do this, loosen the Sacral Pad locking knob and slide the
pad to that it is flush against the patient’s sacrum.
9. Insert the Lower Extremity Compression Device into the receiving tube
directly beneath the center of the seat. The Compression Device Locking
Knob should be on bottom with the pads pointing up. Place the patient’s
legs between the anterior and posterior pads and slide the device in
toward the chair until there is firm contact with the femur and the lower
leg is perpendicular to the supporting surface. Tighten the locking knob
for the compression device. Secure pelvic and femur straps.
10. Adjust Scapula Roll to rest between the level of the scapular spines
and inferior angles. To do this, press in simultaneously on the scapu-
lar pad adjustment knobs and slide the pad up or down. Affirm that
this is a comfortable position for the patient.
With the lower torso properly stabilized the patient assumes a
posterior pelvic tilt with a slight degree of knee flexion. Maintenance
of posterior pelvic tilt throughout the range of motion places the
extensor muscles in an elongated position which, when moving into
a flexion posture, allows exercise of a broader range of extensors.
11. If necessary, loosen the Headrest Adjustment Knobs and adjust
Cervical Headrest to below the occipital protuberance, or to patient
comfort.
12. Apply torso straps firmly and adjust clavicle pads on straps for max-
imum patient restraint and comfort. Secure tethering strap across the
patient’s chest.
