SAFETY TETHER OPERATION
(Refer to Figure 14.)
The Safety Tether is factory installed but a few simple adjust-
ments are required to ensure proper operation during
unweighing. The length of the tether strap should equal the
length of the harness rope plus four inches when the harness
rope is fully extended. Follow the steps below to adjust the
safety tether to the correct length.
1. Adjust spreader bar to accommodate patient height.
2. Adjust safety tether strap so that it equals rope length
and add four inches. To adjust the strap length, press in
on the safety tether release and pull up on the strap to
create more slack. Pull down on the free end of the strap
to tighten.
3. After adjusting tether length, there may be excess strap
length that could interfere with patient. If so, use the clip
to adjust the slack strap so it is out of the patient's way.
FREE WHEELING
The Biodex Offset Unweighing System can be used over
the floor or with other exercise devices. Be aware of the
adjustments required when moving from one device to
another. For example, when stepping down from a tread-
mill, the step-up height of the treadmill must be taken into account. This is accomplished by
rotating Handle #1 and lowering the patient. The opposite is true when going from the floor to
the treadmill.
When traveling across the floor there is no need to spin the entire unweighing system around when
the patient runs out of floor space. Simply turn the patient and head in the opposite direction.
NOTE: It is best if the steering casters are behind the patient if the therapist will be steering the unit from
behind the patient. If the patient will be steering the unit, the steering casters should be in front.
JOGGING
The dynamic suspension provides ample dynamics to allow patients to walk briskly or even jog
while attached to the unweighing system.
AMBULATION STOOL
(See Figure 15.)
The Ambulation Stool can be used to provide a posi-
tion from which the clinician can easily observe or
assist patients with foot placement and weight shifting.
To install the stool, hold both stool hinges up (on the
underside of the seat) and slide the stool onto the base
of the left or right support. Lock the hinges in the down
position to secure the stool in place.
