1:Getting Started

Core:Tx is a system that combines software and hardware you can
use as a rehabilitation, preventative, or str engthening tool. The key
hardware is a s mall transceiver that can be attached anywhere on
the body with adjustable straps. Using Motion Track™ technology,
the transceiver senses limb motion relative to a joint and transmits
that information wirelessly to proprietary software.

The software provides motivating and informational feedback for
the patient by providing an entertaining and game-like interface. At
the end of each session or activity, the software provides the patient
with a score.

The system is particularly aimed at exercising neuromuscular
control. In addition, you can set up exercises to emphasize gains in
range of motion or strength. Core:Tx is a versatile tool that is
compatible with and enhances existing rehabilitation, preventative,
and strengthening protocols.

Understanding Core:Tx Terminology

W e use specific terms in Core:Tx and in this guide to describe how
to use and set up Core:Tx:

• Activity—An activity is the selected movement, mode, and
other options in Core:Tx that you set up for a patient. The
Activity panel in Core:Tx shows these settings, guides the
patient’s actions, and displays the patient’s scor e for the activity.

• Exercise—An exercise is the specific motion you have the
patient perform for the activity. For example, if you are
working on knee flexion/extension, the exercise may be squats.

• Mode—You can set an activity in Core:Tx to one of two modes:
– Monitor—Monitor Mode requires the patient to perform a

tracking exercise or to maintain a static joint position.
When you set the speed to greater than zero, the patient
must move through the selected range of motion. When
you set the speed to zero, the patient must maintain the
selected join position.

– Challenge—Challenge Mode requires the patient to keep a

ball on the screen balanced between two opposing forces.
When you set the speed to greater than zero, the balance

1: Getting Started 17

point moves through the selected range of motion. When
you set the speed to zero, the balance point does not move.

• Movement—A movement is a set of motions of a particular

joint of the body. For example, knee flexion/extension and hip
abduction/adduction are examples of movements. You select
the movement in Core:Tx as the first step to setting up an
activity.

3:Setting Up an Activity

After you start Core:Tx and open or create patient data, you are
ready to set up an activity. When you open patient data, the activity
settings default to the last settings you used for that patient.

You can configure the following settings related to a Core:Tx
activity:

• Movement—Make this selection first, because it sets defaults
for the other settings. (See “Selecting a Movement” on
page 31.)

• Mode (See “Selecting the Activity Mode” on page 32.)

• Audio (See “Turning the Audio On or Off” on page 33.)

• Angle (See “Selecting the Activity Angle” on page 34.)

• Speed/Time/Repetitions (See “Selecting the Speed and Total
Time or Repetitions” on page 35.)

• Difficulty (See “Setting the Difficulty” on page 37.)

You can also save an activity’s settings as the default for the system.
For more information, see “Saving Activity Settings as the Default”
on page 38.

Selecting a Movement

A movement is a set of motions of a particular joint of the body. For
example, knee flexion/extension and hip abduction/adduction are
examples of movements.

You should select the movement in Core:Tx as the first step to
setting up an activity, because it sets defaults for the other activity
settings. You can change those default settings as needed.

32 Core:Tx User Guide

Selecting the Activity Mode

The mode in Core:Tx controls the type of activity. You can set an
activity in Core:Tx to one of two modes:

• Monitor—Monitor Mode requires the patient to perform a
tracking exercise or to maintain a static position. When you set
the speed to greater than zero, the patient must move through
the selected range of motion. When you set the speed to zero,
the patient must maintain the selected joint position. This
mode shows the patient an eyepiece to keep over a disc. This is
the default mode for each movement.

• Challenge—Challenge Mode requires the patient to keep a ball
on the screen balanced between two opposing forces. When
you set the speed to greater than zero, the balance point moves
through the selected range of motion. When you set the speed
to zero, the balance point does not move.

Turning the Audio On or Off

You can turn the audio on or off depending on your preference and
environment. When on, the audio provides feedback to the patient
about the activity status. For example, the sound grows louder as
the amount of error increases and softer as the amount of error
decreases. The sound also changes pitch depending on which side
of the disc the eyepiece is (Monitor Mode) or on which side of the
target the ball is (Challenge Mode).

Selecting the Speed and Total Time or Repetitions

The speed setting determines how fast the disc (Monitor Mode) or
target (Challenge Mode) moves. A low number is slow; a high
number is fast.

You can set up a static activity by setting the speed to zero. This
means the disc (Monitor Mode) or target (Challenge Mode) on the
screen does not move.

A static monitor activity measures how well the patient maintains a
specific joint position while performing a selected activity. For
example, the activity can show how well the patient maintains the
lumbar spine in a neutral position while doing spinal stabilization
exercises. When you set up a static activity, you must establish a
“set position” after calibration. For more information, see
“Calibrating the Range of Motion and Starting the Activity” on
page 42.

A static challenge activity requires the patient to perform an
exercise while keeping the ball centered over a stationary target.

You determine the duration of an activity by selecting either the
total time or the number of repetitions. If you select a time,
Core:Tx calculates the number of repetitions. If you select the
number of repetitions, Core:Tx calculates the total time.

The conversion from repetitions to time or vice versa depends on
the selected speed. For example, for a given total time, a faster
speed will result in more repetitions. For a given number of
repetitions, a slower speed will result in a longer total time.

Starting the Activity

After you set up the activity the way you want it, you are ready to
start the activity. For more information about setting up an activity,
see “Chapter 3, Setting Up an Activity” on page 31.

40 Core:Tx User Guide

You must perform the following tasks to start an activity:
1 Position the transceiver on the appropriate part of the patient’s

body. (See page 40.)

2 Calibrate the range of motion and start the activity in the

Core:Tx software. (See page 42.)

Positioning the Transceiver

The transceiver must be securely placed in the proper position
before the patient starts the exercise. Use the straps that came with
the Core:Tx to position the transceiver.

The knobs on the transceiver represent the axis of motion the
transceiver is able to detect. This gives you a visual reference for
proper alignment of the transceiver.

The axis should always be in parallel with the targeted joint axis.
For example, knee joint flexion/extension occurs around a coronal
axis. The transceiver should be placed so that its axis is oriented
along a coronal axis as well.

To position the transceiver:
1 Make sure that the light on the transceiver is on.

• For information about turning on the transceiver, see
“Starting Core:Tx” on page 11, steps 1 and 2.

2 Place the transceiver between the elastic bands of the

appropriate strap.

• For information about which strap to use, see the
appropriate exercise section in “Chapter 7, Lumbar
Stabilization in Sitting Position on Therapy Ball” on
page 59.

the activity. For more information, see “Calibrating the
Range of Motion and Starting the Activity” on page 42.

Calibrating the Range of Motion and Starting the Activity

After you position the transceiver, you must calibrate the range of
motion before you start the activity. This maps the range of motion
to what you see on the Core:Tx screen. You must calibrate the
range of motion at least once when you set up an activity.

For static activities (speed set to zero), you must also tell Core:Tx
the “set position.” This is the position of the joint that you want the
patient to maintain during the activity. For example, the activity
can show how well the patient maintains the lumbar spine in a
neutral position while doing spinal stabilization exercises.

If Core:Tx is not responding to motion or you find that you have to
recalibrate repeatedly while performing an activity, see “Motion
Does Not Display Properly on the Computer Screen” on page 55,
specifically the solutions listed for “Core:Tx does not respond to
motion.”

4: Performing an Activity 43

To start the activity and calibrate the range of motion:
1 In the Core:Tx software, use the arrow keys to select Activity

in the navigation bar and press space bar.

• For information about navigating in Core:Tx, see

“Navigating in Core:Tx” on page 14.

• The Activity Panel displays, showing your settings on the

left side and the word Calibration in the center. The
eyepiece or ball is positioned at one end of the activity
graphic. For more information about the Activity panel, see
“Understanding the Monitor Activity Screen” on page 44 or
“Understanding the Challenge Activity Screen” on page 46.

2 Have the patient move to one extreme of the range of motion.

• Typically, you want the patient’s movement to correspond

to the position of the eyepiece or ball. For example, on a
vertical activity (angle set to 0°), the patient should be at
the highest position when the eyepiece or ball is at the top
of the activity graphic.

3 Press the button on the transceiver or press space bar.

• The eyepiece or ball moves to the opposite position.

4 Have the patient move to the other extreme of the range of

motion.

• Typically, you want the patient’s movement to correspond

to the position of the eyepiece or ball. For example, on a
vertical activity (angle set to 0°), the patient should be at
the lowest position when the eyepiece or ball is at the
bottom of the activity graphic.

5 Press the button on the transceiver or press space bar.
6 If the speed is set to zero (a static activity), have the patient

move to the joint position you want maintained and press the
button on the transceiver or use the Set Position button in the
Core:Tx software.

• After you set the position, the Set Position button changes

to Start.

44 Core:Tx User Guide

7 When the patient is ready to start the activity, use the Start

button.

• After you start an activity, the Start button changes to
Pause. If you need to pause the activity for any reason, use
the Pause button.

• When you pause, everything stops at its current level,
including the eyepiece and disc position (Monitor Mode)
or the ball and target (Challenge Mode), time or repetition
countdown, and the score.

• When you are ready to resume, have the patient position
the eyepiece over the disc (Monitor Mode) or the ball over
the target (Challenge Mode), then use the Start button to
continue where you left off. After you pause the activity, the
Pause button changes back to Start.

Understanding the Monitor Activity Screen

After you configure the activity settings, you can start the activity.
For more information, see “Setting Up an Activity” on page 31. Be
sure to position the transceiver on the patient correctly. For more
information, see “Positioning the Transceiver” on page 40.

For a Monitor Activity, the patient tries to keep the eyepiece
centered over the disc:

• For nonstatic activities, the disc moves along the rails based on
the speed and range of motion you set up. The patient must
perform the exercise you choose at a rate that keeps the
eyepiece centered over the disc through the full range of
motion.

• For a static activity, the patient performs an exercise keeping
the eyepiece over the disc, which does not move. A static
activity encourages the patient to maintain the proper joint
position while performing a selected exercise. For example, the
activity can show how well the patient maintains the lumbar

Understanding the Challenge Activity Screen

After you configure the activity settings, you can start the activity.
For more information, see “Setting Up an Activity” on page 31. Be
sure to position the transceiver on the patient correctly. For more
information, see “Positioning the Transceiver” on page 40.

For a Challenge Activity, the ball does not directly represent the
patient’s position. The patient is essentially balancing the ball
between the magnets on the screen, and the ball is under the
influence of the magnetic force. The patient’s movement also
influences the movement of the ball. The patient must respond to
the ball’s movement away from the target, counteracting this
movement in a controlled manner.

Another analogy is balancing a broom in your hand. In this
analogy, the ball represents the bristles of broom that you ar e trying
to keep aligned with the target.

• For nonstatic activities, the target moves along the rails based
on the speed and range of motion you set up. The patient must
perform the exercise you choose and keep the ball centered
over the target through the selected range of motion.

• For a static activity, the patient performs an exercise keeping
the ball over the target, which does not move.

Understanding the Audio Feedback

The audio feedback gives patients cues about how well they are
doing, in addition to the visual feedback. When on, the audio
provides feedback to the patient about the activity status. For
example, the sound grows louder as the amount of error increases
and softer as the amount of error decreases. The sound also
changes pitch depending on which side of the disc the eyepiece is
(Monitor Mode) or on which side of the target the ball is
(Challenge Mode).

You turn the audio feedback on or off based on the patient’s
preference. Use Activity Setup to change the setting. For more
information, see “Turning the Audio On or Off” on page 33.

Understanding the Score

The score gives you and the patient a measure of how well the
patient is doing. The score measures how close the center of the
eyepiece stays to the center of the disc (Monitor Mode) or how
close the ball stays to the center of the target (Challenge Mode).
The higher the score, the better the patient performed.

The following factors increase the score:

• Total time—Performing the activity fo r a longe r tim e.

• Performance level—Performing the activity better, that is, more
consistently keeping the ball or eyepiece centered.

• Difficulty (Challenge Activity only)—Performing an activity at
a higher difficulty setting.

The activity panel shows both the patient’s score and possible
maximum score, giving the patient a goal to work toward.

Problem or symptom Solution

T ransceiver light blinks at
a fast, steady rate.

T ransceiver light blinks at
a slow, steady rate.

Transceiver does not
come on when I push the
button.

1 Ensure that the base station is connected to

the computer with the USB cable.

2 Place the transceiver on a solid, flat surface

near the base station.

3 Do not move it until the light is on, without

blinking.

• This typically takes less than 30 seconds,
but may take as long as three minutes.

For more information, see “Starting Core:Tx” on
page 11, steps 1 and 2.

Replace the batteries in the transceiver.
For more information, see “Inserting the

Batteries into the Transceiver” on page 8.
Check that the three AAA batteries in the

transceiver are charged and installed properly.
For more information, see “Inserting the

Batteries into the Transceiver” on page 8.

6: Troubleshooting 55

Motion Does Not Display Properly on the Computer Screen

Problem or
symptom

Core:Tx does not
respond to motion.

Solution

1 Make sure the transceiver is properly oriented so

that its axis of motion, shown by the knobs, is
aligned with the joint’s axis of motion, as
described in “Positioning the Transceiver” on
page 40.

2 Make sure the base station is connected to the

computer’s USB port.

• If it is not connected, close the Core:Tx
software, connect the base station, then restart
the Core:Tx software.

• For more information, see “Connecting the
Base Station” on page 10.

3 Make sure the transceiver light is on and not

blinking.

• If it is not on or it is blinking, see the
appropriate solution in “T ransceiver Light Blinks
or Does Not Come On” on page 54.

4 Ensure that the base station lights are both on.

• If both are off, it is not powered by the
computer. Connect the base station to the
computer’s USB port. For more information,
see “Connecting the Base Station” on page 10.

• If one is on and one is off, it is not receiving a
signal from the transceiver. Check the
transceiver and see the appropriate solution in
“Transceiver Light Blinks or Does Not Come
On” on page 54.

• If the problem remains, perform the link-up
process as described in “Linking Up the
Transceiver and Base Station” on page 56.

56 Core:Tx User Guide

Problem or
symptom

Activity graphics are
jerky or do not have
good detail.

Movements on the
screen do not match
your transceiver’ s
movements

Solution

Your computer may not have a graphics card that is
able to display the graphics that Core:Tx uses. The
system will work properly, but the display on your
screen will not look as good as it can.

Your Core:Tx base station may be picking up signals
from a transceiver being used by another person.
Ensure that the transceiver and base station you are
using are linked to each other as described in
“Linking Up the Transceiver and Base Station” on
page 56.

Linking Up the Transceiver and Base Station

If you have received a replacement transceiver or base station, you
must perform the link-up process the first time you use the new
component. This process ensures that the transceiver and base
station “speak the same language” to each other. We call this
process linking up.

You may also need to perform this process if technical support
personnel tell you to do so.

To link up the transceiver and base station:
1 B e s ure that the base station is connected to your computer.

• For more information, see “Connecting the Base Station”
on page 10.

2 Start the Core:Tx software.

• For more information, see “Starting Core:Tx” on page11,
starting with step 3.

• The Link-up panel displays. While the base station and

transceiver attempt to link up, the signal strength icon will
be yellow.

• When the signal strength icon turns green, the link-up

process is complete.

• If the signal strength icon turns red, r eplace the batteries in

the transceiver, then repeat steps 5 through 7. For more
information, see “Inserting the Batteries into the
Transceiver” on page 8.
