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 buckles 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 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 mechanism that raises and lowers the
yoke. The actuator 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: 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.
HANDLE BARS: Unit has two adjustable handlebars.
The handlebar s 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
the 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.

switch. Release the button when the yoke is at the
desired 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 Raised
Emergency Lowering of Yoke
If the down buttons fail to lower during normal use due
to a low battery. There is an auxiliary down button that
can be pressed to lower the device. Using a pen tip or
small screwdriver, press the black emergency down
button, this lowers one of the two columns of the
LiteGait® when pressed.

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.

BiSym Scale (Optional)
BiSym is a unique option available with LiteGait® to measure unilateral or bilateral support. LiteGait®’s special design
includes a two-armed yoke which holds the patient above each shoulder. From these two points, the harness system
can be adjusted to provide as much or as little support required to each side of the body. The range of support can
vary on each side from full to no support.
BiSym measures this asymmetric support at any given time during the gait cycle. Each arm of the yoke is
instrumented with a load cell with electrical connections to a box at the base of the yoke. This electronic box powers
the load cells, processes the signals and displays the supported loads of each arm or total support on a display unit.
This can be used for charting of therapy progression as well as accommodation of weight bearing status.
Optionally, digital outputs representing the supported loads on both sides of the body are provided for digital
recording on to a PC.
These signals vary as the weight bearing load changes from the right to left side during the gait cycle. This can be
used as biofeedback for the patient. The more weight bearing by the patient = better posture = less work by machine
= smaller BiSym reading.
Connecting the BiSym
Connect Corresponding Load Cell wires from BiSym ready LiteGait®
yoke into BiSym Scale.
Slide BiSym Scale onto the pre-installed bracket at the base of the yoke.
NOTE: Proper installation will leave the monitor visible to the patient supported
in the LiteGait®
Using the BiSym Scale
Press any button to turn the BiSym Scale on.
The BiSym Scale has an AUTO SHUT-OFF that can be adjusting during the CHANGE SETTING? mode (see below)

tual weight of the patient.
Charging the BiSym Scale
The BiSym scale battery is charged by a charger separate from the LiteGait® device. The
BiSym battery should be charged for 6 - 8 hours or overnight once per month.
The BiSym is connected to the BiSym Battery cable located at the top of the LiteGait.
Disconnect the battery cable from the BiSym Scale.
Plug the male end of the charger cable into the female end of the battery cable. Plug the
charger into the appropriate 110 or 220 volt outlet.
