In an injured joint, proprioception may be compromised. As a result, muscle activity associated with the joint is not well synchronized, thereby reducing dynamic stability. This in turn
increases the risk of further injury. stability is important in preventing reinjury in both early and late

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.

If you export to an existing data file and the same patient name appears in the existing data file and the data you are exporting, Core:Tx merges the data.
Note
Core:Tx assumes that patients with the exact same name are the same patient. The merged data contains both the data you exported and the data that already existed in the data file.

Importing Core:Tx Patient Data

Core:Tx stores patient data in a database. You can import Core:Tx patient data that has previously been exported fr om Core:Tx or that you backed up from Core:Tx. You may want to do this if you need to share Core:Tx data with another Core:Tx user or with the patient, or if you are moving Core:Tx to another computer.
The import process adds the patients to the current database. It does not overwrite (delete) existing data in the database.
You must first export patient data from Core:Tx on another computer or create a backup, then you can import it into Core:Tx on your computer. For mor e information, see “Exporting Core:Tx Patient Data” on page 24 and “Backing Up the Core:Tx Database” on page 28.

Backing Up the Core:Tx Database

Core:Tx stores patient data in a database. You can back up the database to removable media such as a floppy disk, compact disc (CD), or flash drive (a small storage device that connects to a USB port). This lets you store the data in another location for safe keeping or move the entire database to an other computer where you want to use Core:Tx. We recommend backing up your data regularly.
After you back up the Core:Tx database, you can import the backup file into Core:Tx. You may want to import the database from a backup file if you lost your original database because of a hardware failure, or if you want to move the database to another computer. For more information, see “Importing Core:Tx Patient Data” on page 26.

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.

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.

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.

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.
