ABOUT YOUR UNIT
LiteGait® is comprised of several parts:
YOKE: The yoke is a Y-shaped piece that has four female buckles at the ends. It is
attached to the actuator with a flat plate secured by four bolts.
OVERHEAD STRAPS: The overhead straps consist of 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. The overhead straps provide postural support for the patient.
HARNESS/GROIN PIECE: The harness is an adjustable wrap with a buckle closure in
the front and three adjustable straps on each side. There are four male connectors
at the top of the harness that attach into the female buckles of the overhead straps.
The four female buckles at the bottom of the harness allow for the connection of the
groin piece. The H-shaped stitching on the groin piece denotes the top (or body
side) of the piece.
ACTUATOR: The actuator is the mechanism that raises and lowers the yoke. It
consists of a concentric expanding and retracting square tower that houses the DC
motors, gearing and the screw mechanism. It also provides the structural base to
which the adjustable handlebars are attached.
CONTROL UNIT: The control unit is the junction box for the battery power, handheld
switch and contains electrical safety protection circuitry. It is located within a
compartment of the actuator. The battery pack connects to this unit and is also
located within a compartment of the actuator.
HANDLEBARS: Your unit has two adjustable handlebars.
The handle bars are
attached to the unit using two knobs. (Note: Over tightening the knobs may cause
damage)
BASE: The base consists of two horizontal bars connected by two U-shaped tubes.
The base has an open end and a closed end where the actuator and battery pack
are placed. 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. Two locks on one side of the base
are locking brakes and the two on the opposite side are directional locks. Be certain
to lock both caster brakes when using the unit over a treadmill or when connecting
the patient to the unit. NEVER leave the patient unattended in the unit.
BISYM (Optional): The BiSym Scale is installed on top of the actuator and 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.

How to adjust the height of the yoke
The LiteGait powered yoke is raised and lowered by a hand- held switch with two
up and two down arrows.
Raising the yoke: Verify that LiteGait has clearance above the yoke. Press the
up arrows on the hand-held remote switch. Release the button when the yoke is
at the desired height.
Lowering the yoke: Verify that LiteGait has clearance below the yoke. Press
the down arrows on the hand-held remote switch. Release the button when the
yoke lowers to the desired height. Maintain at least 5" clearance above the
patient's head.

Overhead Buckles and Straps
Each of your unit’s four straps can be individually adjusted. Adjust each strap to
assure that the patient is in a fully upright position in the correct posture for
walking.
1. To tighten straps:
With one hand pull up on the strap attached to the harness.
With the other hand, pull down on the free end of the strap.
2. To loosen straps:
With one hand, hold the overhead buckle outwards.
With the other hand pull down on the part of the strap attached to
the harness.
3. To prevent the patient leaning to one side, e.g. right side:
Tighten the front and back straps on the right side.
4. To prevent the patient from leaning forward:
Tighten the right and left FRONT straps.
5. To prevent the patient from leaning backward:
Tighten the right and left BACK straps.
3. To prevent the patient leaning to one side, e.g. right side:
Tighten the front and back straps on the right side.
4. To prevent the patient from leaning forward:
Tighten the right and left FRONT straps.
5. To prevent the patient from leaning backwards:
Tighten the right and left BACK straps

Harness Application
Harness and Groin Piece Preparation
1. Pick the appropriate harness and groin piece for the patient (based on patient girth).
2. Estimate the harness girth before placing on the patient by folding the harness in half
so that the ends meet. Then, hold the harness in front of the torso to estimate the width
from one side of the body to the other.
3. Tighten or loosen the 3 rows of side straps on each side of the harness. (To loosen
the side straps lightly pull up on the black tabs on the side buckles.)
4. Keep the harness folded in half and align the top buckles so that they are adjacent
with each other.
5. Take the groin piece and adjust the groin strap padding towards the center of the
strap before putting it on.
6. Adjust the front groin straps so they are equal in length.
7. Adjust the back groin straps so they are equal in length.
8. Attach the groin piece to the back of the harness.
9. The side of the groin piece with the H-outline stitching (most padded) will go against
the patient’s body.
How to put on the Harness
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.
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 straps. The
bottom four buckles attach to the groin piece and do not extend past the bottom seam of
the harness.

Harness Application in Supine (Laying on Back)
1. Patient should be lying down on his/her back.
2. Place one end of the harness on the mid‐lower abdomen.
3. Roll the patient on his/her side away from you.
4. Place the harness on the center of his/her back so that the top buckles are equal distances
from the spine.
5. Place the lowest harness side strap over the greater trochanter. The greater trochanter is a
boney prominence on the side of the upper leg approximately on patient’s hand length below
the waist.
6. Pass the groin piece between the legs to the front.
7. Tighten the groin piece at the back leaving enough length for the front to attach.
8. Hold the harness with your hand.
9. Roll the patient back onto his/her back.
10. Wrap the harness to meet the other end in front.
11. Attach the front buckles.
12. Check the midline position of the harness by feeling for both upper buckles behind the
patient’s back. (They should be the same distance from the spine.)
13. Rotate the harness to adjust, if necessary.
14. Tighten the lower side straps first, as symmetrically as possible. These straps are crucial to
the proper distribution of the patient’s weight and should be as tight as possible. To ensure a
snug fit, pull the strap closest to the body towards its black plastic buckle with one hand while
pulling the free end with your other hand until you cannot pull anymore.
15. Tighten the middle and upper side straps. Make sure to tighten both sides symmetrically
(equally) so that an equal strap length remains on each side. These should be as tight as the
patient can tolerate without discomfort. The top strap should not interfere with breathing.
Bulges of fatty tissue should be apparent (visible on most patients) as the harness is tightened.
These bulges are very important and will allow the harness to securely grab onto the soft tissue
of the abdomen, keeping the harness securely in place throughout the training.

USING YOUR LiteGait®
Harness Application While Standing
1. Wrap the harness around the patient’s torso.
2. Place the lowest strap over the greater trochanter.
3. Attach the front buckles.
4. Tighten the lowest straps first (see Tightening side straps section).
5. Attach the groin piece (see Groin piece attachment section).
Groin Piece Attachment
1. Attach the groin piece to the front harness buckles. The stitched side of the groin piece
should be facing up against the body.
2. Hold the padded part of one end of the groin piece with one hand.
3. Pull it against the patient’s leg. Keep holding it while the other hand pulls the free end of
the groin strap.
4. Tighten the groin strap snugly so there is NO slack.
5. Repeat on the other side.
6. Pull out any wrinkles or bunching from the patient’s clothing.
7. Sit the patient up or stand the patient, if safe
ENSURE AT ALL TIMES THAT THE BOTTOM STRAP OF
THE HARNESS IS AT THE LEVEL OF THE GREATER
TROCHANTER (HIP JOINT CREASE).
Contrary to what may seem reasonable, 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.

USING YOUR LiteGait®
How to Connect the Harness to your LiteGait
1. Lock the caster brakes.
2. Adjust the yoke to the correct position, giving the patient approximately 5-6 inches of
head clearance.
3. Extend the overhead straps until they are long enough to reach the upper connection
on the harness. Attach the four buckles that hang from the overhead straps to the
appropriate buckles on the harness. Pull on the straps until taut.
4. With the patient in the harness, bring the patient into a standing position directly
under the yoke buckles. Have the patient hold the handlebars. Adjust the handlebar
height to suit the patient.
5. Your unit can now be used for over ground therapy, or to assist the patient in
stepping onto the treadmill.
6. With higher level patients, the unit may be positioned over the treadmill before the
patient is buckled into place.
NOTE: Under no circumstances should a patient have
ALL the weight removed from the legs for more than two
minutes at a time.

Control Unit
Control Box is the junction box (connecting point) for LiteGait power system. The
actuator cord(s), the handheld switch, the battery, and the power cord all plug
into this unit. It is located in the base opposite to the battery side and is equiped
with a red STOP button for emergency shut down. Press this button to cut the
power to the actuator and stop all movements or lifting action. Twist the red
button to power up before using the lift mechanism.
On the control box there is a small digial display which notifies you of the
remaining battery life. It will indicate a fully charged battery with four bars. Once
the battery charge is depleted to below 50% a plug icon appears in the display
suggesting it is time to recharge the batteries. Below 25% charge the word
STOP appears on the display.
In order for the contorl box and LiteGait to work, the charging cord must be
unplugged from the wall, the red button must be released and the battery must
be charged.

Adjusting the Handlebars
Raising and lowering the handle bars: 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.

Base and Casters
Total‐Lock Caster
LiteGait is equipped with four or six casters. Half are total‐lock casters and half directional lock
casters. Each leg has one type of caster and it is clearly marked. Directional lock casters have a
green or black brake lever. Standard casters have a gray or silver brake lever.
To lock the total‐lock casters press the caster brake until you feel the brake snap into place.
The caster brakes should be locked whenever the LiteGait is not being moved over the ground.
CAUTION: While locking the casters 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 and away from stairs
and ramps. NEVER leave a patient unattended in the unit.

USING YOUR LiteGait®
Base and Casters
Directional‐Lock Caster
Directional lock casters facilitate rolling the device back and forth over a treadmill
or down a hallway. The directional lock casters will have a green brake. Once
the unit is positioned over a treadmill, all four caster brakes need to be locked.
1. Position LiteGait near the treadmill (or where you wish the patient to begin
walking).
2. 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).
3. Press the directional locks. This will prevent the caster from swiveling.
4. LiteGait can now be easily rolled back and forth over the treadmill or on a
straight path in the therapy room or hallway.
NOTE: When walking patients over ground, first
establish the direction of movement, then lock the
directional casters to ensure the best performance.
To move in the opposite direction, release the caster
brakes and re-establish the direction of movement.
That is, allow the casters to follow the movement rather
than lead it.
