WARNING: LiteGait® Handlebars are designed to be used as a
balance aid while using the LiteGait. Excess loading of the
handlebars may damage handlebars. Avoid Having patients
lift their weigh using the handlebars.
VII. Adjusting Handlebars
Raising and Lowering the Handle Bar
Loosen each knob in equal portions. The knobs should
only need to be turned once to free the handlebars.
Once the knobs are loosened slide the handlebars to the
desired height. Hand tighten both knobs equally. The
knobs should only need to be tightened one rotation.
VIII. 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
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.
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
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.
BRAKE
STEER
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.

Using Your LiteGait®
IX. 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.
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.
