1. Introduction
Intended Use
Designed specifically for rehabilitation and retraining of gait for patients with neurologic and
orthopedic gait dysfunctions, the Biodex Gait Trainer provides both the audio and visual
feedback needed to progress patients quickly and safely to normal ambulation.
The Gait Trainer is easy to use. The clinician need only select the patient’s age and height for
the treadmill to automatically calculate the exact speed needed to achieve desired step cycle.
The rhythmic movement and the audio feedback provide patients with added stimulus for
retraining of neural pathways to improve gait pattern.
The Gait Trainer promotes correct stride length for early phase patients. By starting out slowly
(with the zero starting speed and small, one-step cycle speed increments), it is possible to
manually position the patient’s lower extremities in the desired patterns for gait thus
reinforcing the proper techniques early in the rehabilitation process. As the patient progresses,
correct stride length is coupled to the correct step cycle. When belt speed is increased, the
patient must either take longer or more strides to stay on target. Normative data allows
clinicians to compare patient progress to baseline norms.
Indications for Use
Of course, the Gait Trainer can also be used for many other rehabilitation treadmill
applications. In the treadmill mode, its unparalleled speed control, durability, incline and
decline in both forward and reverse directions, digital feedback, low profile, and choice of
handrail configurations make it the ideal choice for virtually any patient young or old.
The Biodex Gait Trainer comes with a printer that is easy to install and resides on the printer
stand.
Assembly and Installation
The display monitor receives power from the larger Gait Trainer device. Therefore, the Gait
Trainer must be plugged into a wall outlet or surge suppressor and powered on by the ON/OFF
switch at the front base of the unit.
The Gait Trainer deck is instrumented with a strain gage at each of the four corners. It is
important that the Gait Trainer be level for optimal footfall detection. When not level, the user
may see messages concerning Leveling or Offset Calibration. Depending on the situation,
instructional screens will be displayed leading the user through any required process.
When first installed, or if the Gait Trainer is moved, the leveling foot may require an
adjustment. This will require a ¾” wrench. Adjust the rear leveling foot by turning it with the
wrench until the on-screen gage turns green. Please note that there is a jam nut that should be
loosened first, and re-tightened after leveling the foot. Press <OK>.

Power-down
In order to prevent the device’s database from becoming corrupted, it is essential that the
correct power-down sequence is performed. Always turn off the display, by touching the “X” in
the upper right corner of the home screen, followed by “Shut Down”.
Figure 1.5. Power-down sequence.
Once the display has finished its shut down sequence, power may be removed from the
treadmill using the main ON/OFF switch located on the front of the base where the power line
cord enters the treadmill.
CAUTION: Do not unplug the device or turn off the ON/OFF front base switch
before powering down the display!
ATTENTION: Ne débranchez pas l 'appareil ou n'éteignez pas le commutateur
de la base avant avant d' éteindre l 'écran!

Initial Setup and Activation
When the system is first powered on, the following screen is displayed if someone is standing
on the treadmill deck:
Figure 1.7. Footfall Initialization Screen
Note: It is important to not be standing on the treadmill deck when OK is selected to perform
the footfall initialization. The footfall initialization calibrates the treadmill sensors to patient
footfalls. Standing on the treadmill deck while the initialization is in process, will result in
inaccurate footfall readings.
Printer Installation
1. Refer to the supplied printer manual to unpack the printer and ensure that it has not been
damaged by shipping.
2. Position the printer on the Biodex-provided printer stand.

16 Biodex Medical Systems, Inc. © 2017

the printer.
4. Insert the AC plug end of the printer power cable first into the Biodex-provided power
adapter, and then insert the adapter plug into the power cable receptacle on the back, lower
base of the Gait Trainer 3. Do not connect any other equipment to this receptacle.
5. Locate the Biodex-provided 15ft USB cable that will be pre-installed in one of the USB ports
on the Gait Trainer 3 display. Connect the other end of the cable to the port at the back of
the printer.
6. Ensure both cables are positioned such that they will not interfere with the patient or get
caught in the Gait Trainer 3 platform or handles.
7. Refer to the printer manual for directions on installing ink cartridges and paper.
8. With power ON to the Gait Trainer 3, press the <Power ON> switch on the printer. Refer to
the printer manual for additional printer information.

Trainer 3.

GAIT TRAINER 3 (v3.X SOFTWARE) 17
Connecting Components
In addition to the printer that is shipped with the Gait Trainer, other printers may be used with
the device. Most Windows 7 printers are compatible with the Gait Trainer display, but the
drivers for many of those printers may need to be installed. For help with this, please call
Biodex Customer Support at 631-924-9000, Option 3. Similarly, any Windows 7 keyboard or
mouse will automatically connect using one of the USB connections.
It is possible to connect the device to a printer wirelessly. Please call Customer Support for
instructions.
An external monitor can also be connected via the VGA port on the bottom of the display. Once
the external monitor’s cable is connected, the <Mirror to External Monitor> button in System
Utilities must be selected. (This button is accessed by the following navigation steps from the
Home screen: Utilities > Configuration > System Configuration > Screen Configuration.)
Accessing Additional Ports and Connections
The Gait Trainer provides the user with the ability to access additional ports and connections
from the back, bottom side of the monitor. These connections can be used to attach an
additional printer, external monitor, or other component. In the example below, the monitor
has been removed from the device column for demonstration purposes.
To access these ports and connections, the back of the monitor can be temporarily removed as
detailed in Figure 1.9.

2. Gait Trainer Mode
The Biodex Gait Trainer can be used for gait training applications or as a rehabilitation
treadmill. The following section describes use in the Gait Trainer Mode. The rehabilitation
treadmill operation is described later in this manual.
Gait Trainer Mode
The Gait Training Mode is useful for the rehabilitation and retraining of gait for patients with
neurological and orthopedic gait dysfunctions. It provides both audio and visual feedback for
the patient. The rhythmic movement of the treadbelt, along with the audio and visual
biofeedback, provides the necessary stimulus for retraining neural pathways thus improving
gait pattern.
NOTE: It is recommended that the Biodex NxStep Unweighing System be used in conjunction
with the Gait Trainer to provide a safe environment for the patient and clinician, and also to
allow for proper patient positioning for weight distribution and coordination of balance.
The Opening Menu displays three icons: Gait Trainer, Treadmill, and Utilities. Touch <Gait
Trainer> to advance to the Patient Setup screen. This screen allows entry of patient information
and parameters used for gait training.
Figure 2.1. The Gait Trainer Opening Menu.
NOTE: Please be aware that entering patient information into the system for the first time will
require some effort. This information is very important if reports are to be run for statistical
purposes. After the initial set up, information for existing patients is very quickly retrieved
making the session set up faster and easier.
The Gait Trainer Patient Setup Screen
At the Patient Setup screen, touch the appropriate icon to begin entering information. A pop-
up keypad is used to enter some parameters such as Name and Age. Once the desired
information is entered/selected, touch <Next> to advance to the Footfalls/Histogram screen.
