About Your LiteGait®
NOTE: Your LiteGait® may look different than image above
LiteGait® is comprised of several parts.
YOKE: Y-shaped support that has four female buck-
les at the ends and is attached to the actuator with a
flat plate secured by four bolts.
OVERHEAD STRAPS: Four 44” long adjustable straps
with male connectors at one end and padded female
buckles at the opposite end. The male connectors
attach to the yoke buckles and the female buckles
attach to the harness providing postural support for
the patient.
HARNESS/GROIN PIECE: Adjustable wrap with a
buckle closure in the front and three adjustable
straps on each side. The four male connectors at the
top of the harness that attach into the female buck-
les of the overhead straps. The four female buckles
at the bottom of the harness allow for the connec-
tion of the groin piece. The H-shaped stitching on
the groin piece denotes the top (or body side) of the
piece.
ACTUATOR: The mechanism that raises and lowers
the yoke. The actuator consists of a concentric ex-
panding and retracting square tower that houses the
DC motors, gearing and the screw mechanism. It
also provides the structural base to which the adjust-
able handlebars are attached.
CONTROL UNIT: Junction box mounted in the base
for the battery power, handheld switch and contains
electrical safety protection circuitry. The battery pack
connects to this unit and is also located within a
compartment of the actuator.
HANDLEBARS: Unit has two adjustable handlebars.
The handle bars are attached to the unit using two
knobs.
BASE: Two horizontal bars connected by two U-
shaped tubes. The base moves freely over ground or
can be locked into place during use over a treadmill.
However, your unit must be locked into place at all
other times.
CASTERS: Four casters are attached to the base. The
two casters on the left side are total locking and the
two casters on the right are directional locking. Be
certain to lock both caster brakes when using the
unit over a treadmill or when connecting the patient
to the unit.
BISYM (Optional): Provides a display of the pounds/
kilograms of support provided by each arm of the
yoke. The load cells that are installed in the yoke
sense the load on the yoke and feed it to the BiSym
Scale for processing and display.
NOTE: Over tightening the knobs may cause damage.
WARNING: NEVER leave patient unattended in the unit.

Using Your LiteGait®
I. Raising and Lowering Yoke
The LiteGait® MX actuator is raised and lowered by a
hand switch with one up and one down arrow.
Raising the Yoke
Verify that LiteGait® has clearance above the yoke.
Depress the button with the up arrow on the hand
switch. Release the button when the yoke is at the de-
sired height.
Lowering the Yoke
Verify that LiteGait® has clearance below the yoke.
Depress the button with the down arrow on the hand
switch. Release the button when the yoke lowers to
the desired height.
Lowered Yoke Raised Yoke
II. Charging the Yoke
The LiteGait® 100MX and 200MX are equipped with a
24 volt battery pack that needs to be charged on a
weekly schedule. To recharge your battery follow the
steps below:
Step 1:
Insert the end of the charger into the charging port on
the control box.
Step 2:
Plug the charger into the appropriate 110-volt.
Step 3:
Leave LiteGait® on charger for 6-8 hours or overnight
once per week. The time it takes to recharge the battery
pack depends upon the health of the battery pack and
how low the battery pack was before charging began.
Step 4:
After charging the LiteGait® unplug the charger from the
WALL OUTLET AND LiteGait® .
Note: Leaving a charger connected to the LiteGait® while dis-
connected to the wall outlet device decreases the battery life
of the LiteGait® battery. Disconnect the charger from the
WALL OUTLET and LiteGait® to reduce frequency of replacing
the LiteGait® Battery.
Low Battery Indicator Alarm
The LiteGait® unit emits an audible noise when the
charge of the battery is critically low and needs to be
recharged. If you experience audible noise, make sure to
charge promptly after use of the LiteGait®. The LiteGait®
will ONLY lift and lower approximately 2 to 3 more times
before shutting off. The LiteGait® should be charged
before running down to a point where you are unable to
lower a patient.
NOTE: Your LiteGait® may look different than images above

Using Your LiteGait®
Charger
The LiteGait® battery is charged using a low current, hos-
pital guideline approved charger. The charger has an in-
dicator LED light that turns green when the charger is
plugged in and not connected to the LiteGait®. When the
battery is charging the LED turns red and then back to
green after the battery is fully charged.
Green Light
The charger is plugged into the socket (if
the battery is disconnected).
The battery is fully charged (If the
battery is connected and the charger is
plugged into the socket
Red Light
The battery is being charged by the
charger.
Below is a graphic showing the location of all cable that
plug into the control box for the LiteGait®. During use
the battery cable and hand switch cable should be
connected. When charging, the charger cable should be
plugged in and the LiteGait® should not be used.
Note: Ensure that all plugs are inserted completely and se-
curely.
III. Adjusting Handle Bars
Raising and Lowering the Handle Bar
Loosen each knob in equal portions. The knobs should
only need to be turned once to free the handle bars.
Once the knobs are loosened slide the handle bars to
the desired height. Hand tighten both knobs equally.
Again, the knobs should only need to be tightened one
rotation.
WARNING: LiteGait® Handle Bars are designed to be used as
a balance aid while using the LiteGait. Excess loading of the
handle bars may damage handle bars. Avoid Having patients
lift their weigh using the handle bars.

IV. Base and Casters
LiteGait® is equipped with four casters. There are two
total locking casters and two directional lock casters.
Each leg has one type of casters, the total locking are
mounted on the left leg the directional locking are
mounted on the right leg.
Directional Lock
Total Lock
Press tab to lock Locked Caster
Locking and Unlocking Casters
Directional Locking Casters
Directional lock casters are indicated by a green
sticker in the locking lever. To lock the directional
locking casters, press the tab and align the caster with
the frame. Once Aligned this locks the swivel of the
casters and is beneficial for walking in a straight path or
placing LiteGait® over a treadmill. Once the unit is
positioned over a treadmill, all four caster brakes need to
be locked
Directional Locking Casters with Treadmill
Position LiteGait® near the treadmill (or where you
wish the patient to begin walking).
Roll LiteGait® towards the front of the treadmill, until
the casters line up parallel to the treadmill (or
parallel to the path the patient will follow—a
hallway for example).
Press the directional locks to lock swivel of casters
LiteGait® can now be easily rolled back and forth over
the treadmill or on a straight path in the therapy room or
hallway.
NOTE: While locking the caster prevents rolling of the unit, it
DOES NOT prevent the unit from sliding on a sloped, slippery
floor. The unit should only be used on a flat floor away from
stairs or ramps. NEVER leave a patient unattended in the
unit.
STEER
Total Locking Casters
Total locking casters are indicated by a red
sticker on the locking lever. To lock the total locking
casters, press the tab until the brake snaps into place.
The caster will lock the swivel of the caster and rotation
of the wheel. Locking all four casters will make the
device stationary.

V. Harness Application
The harness was designed to support a patient in an upright position, allowing for full hip extension. This upright
posture plays a critical role in the effectiveness of the gait therapy performed with partial weight bearing.
Using Your LiteGait®
Set the Left Zero by pressing the SET button.
Harness Components
The front of the harness wrap refers to the point at which the two ends of the harness meet. The harness can be worn
with the closure either in the front or in the back. There are four buckles on the top and bottom of the harness wrap.
The four top buckles extend beyond the harness from the top seam and attach to the LiteGait® overhead straps. The
bottom four buckles attach to the groin piece and do not extend past the bottom seam of the harness.
Preparing Harness for Application
1. Pick the appropriate harness (based on patient’s girth) and groin piece (based on patient’s anterior -posterior
diameter) for the patient.
2. Adjust the groin strap buckles so there is symmetry in the straps-- equal strap length available on both ends of the
padded groin piece and equal from side to side.
3. Attach the groin piece to the back of the harness.
NOTE: The side of the groin piece with the H‐outline stitching (most
padded) will go against the patient’s body.
Front
Overhead Straps
Groin Pieces
Girth Adjustment
Estimating the Starting Size
Half the Girth Test
1. Estimate the harness girth before placing on the patient by folding the unbuckled
harness in half so that the ends meet.
2. Hold the folded harness in front of the patients torso to estimate the width from one
side of the body to the other.
3. Tighten or loosen the three rows of side straps on each side of the harness to
estimated girth.
Symmetry Test
1. With the unbuckled harness folded in half, check the alignment of the top buckles (the
ones that attach to the overhead straps of LiteGait). The buckles should line up / be
adjacent to each other . If not adjacent , make small adjustment to side straps as
needed to regain symmetry. Each side strap should be similarly lengthened to achieve
symmetry.

Harness Application - While Standing
1. Wrap harness around patient with lowest side straps even with GREATER
TROCHANTER.
2. Connect buckles top to bottom.
3. Adjust side straps* to the patient from bottom to top, alternate sides and
tighten evenly. Be sure to maintain harness position at Greater
Trochanter.
* To Tighten, push slack of strap towards buckle, while pulling free end as
shown. Do not tighten top buckles over rib cage.
Quick Check
 2 fingers should NOT fit between strap and body.
 Bulges of tissue may be present between girth adjustment straps if
adjusted appropriately.
NOTE: A loose harness will ride up when overhead support is applied. This will
cause discomfort in the groin region. A snug harness with no slack will grab the
pelvic girdle and hold in place distributing weight evenly throughout harness
wrap.
Attaching Groin Pieces
1. Route the groin piece between legs to front.
2. Connect both buckles - one on each side.
3. Tighten the groin strap snugly so there is NO slack.
To tighten, grab the groin strap or strap cover and:
i. Pull out toward adductor surface of leg.
ii. Pull up toward groin piece buckle.
iii. Use other hand to pull down on excess strap on free end, then
repeat on other leg.
iv. Tighten back straps in the same fashion to remove all slack.
Quick Check
 Groin Piece should have NO Slack. Padding should be equal front
and back. Padding should cover most of the inner leg with little or
no exposed strap.
 Pull on top buckles, if harness moves up torso, straps require
additional adjustment.

NOTE: A LOOSE GROIN PIECE DOES NOT IMPART GREATER COMFORT TO THE PATIENT, BUT ALLOWS THE
HARNESS TO SLIDE UP THE TRUNK, PUTTING UNWANTED LOAD/FORCE ON THE GROIN AREA. TIGHTEN
THE GROIN STRAP SO THAT NO SLACK REMAINS IN THE STRAPS. THIS ASSURES THAT THE HARNESS WILL
NOT RIDE UP ON THE PATIENT.

20 www.LiteGait.com
1-800-332-9255
CAUTION: SITTING WHILE IN THE LEG STRAPS WILL DISPLACE THE HIP AXIS OF
LOCATION AWAY FROM AND OUT OF THE LEG STRAPS; REPOSITIONING OF THE LEG
STRAPS WILL BE NECESSARY.
Leg Strap Application
1. Wrap Velcro thigh cuff portion below bulk of thigh and above knee so strap does
not interfere with knee function.
2. Strap should be perpendicular to ground and pointing up toward the hip on the
outside of leg.
3. Connect male buckles on leg straps into plastic groin piece female buckles.
4. Tighten all three straps keeping center strap perpendicular to the ground and on
the lateral surface of the leg. The bifurcation point on the strap (where the strap
splits into two) needs to be at the hip joint axis of rotation to maintain symmetry.
5. Straps must be tightened completely, using a two-handed technique and getting
rid of all slack, to properly anchor the harness in place and properly transfer the
support to the thighs.
Harness Application –In Supine
1. Roll patient away from you.
2. Attach groin piece and place harness on patient with half of the harness rolled and
under patient. (Figure 1)
3. Hold harness in place with lowest strap at greater trochanter
4. Roll patient into supine.
5. Pull harness around.
6. Straighten harness. Reach behind patient to feel back buckle position. Check for
symmetry. (Figure 2)
7. Connect front buckles
8. Tighten all 6 side straps with leg straight. (Figure 3)
9. Connect the groin piece to the front buckles and tighten as in previous section.
(Figure 4)
10. Roll patient away from you
11. Tighten back straps of groin piece, removing all slack. (Figure 5)
Quick Check
 Harness should be equally spaced from side to side
