Foreword
The Facts about Neuromuscular
Reeducation (NMR)
Neuromuscular control is essential to maximizing a patient’s
functional outcome. In a healthy joint, proprioceptive information
is relayed to the central nervous system triggering a coordinated
muscular response.1This coordinated effort controls joint
excursion and loading,2which enables dynamic joint stability and
prevents injury.3
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.4Clearly, improving joint
stability is important in preventing reinjury in both early and late
stages of the recovery period.5A complete rehabilitation or
performance enhancement program should, therefore, address
these neural deficits to maximize recovery and prevent injury
recurrence.6

1:Getting Started
Core:Tx is a system that combines software and hardware you can
use as a rehabilitation, preventative, or strengthening tool. The key
hardware is a small 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.
About This Guide
This guide tells you how to set up and use Core:Tx. It assumes that
you have a basic understanding of how to use the Windows
operating system.

2 Core:Tx User Guide
Fonts and Symbols
This guide uses several fonts and symbols to help explain how to
use Core:Tx.
Core:Tx Overview
Your Core:Tx system has several components that work together to
give you a versatile rehabilitation tool. The package contents
include the following, as shown in Figure 1:
• Base station
•Transceiver
• Universal Serial Bus (USB) cable
• Three AAA batteries
• Six straps and one strap extension
• Software installation CD
•Core:Tx User Guide (this document)
• Core:Tx Quick Start Guide
• Product registration card
Font or Symbol Definition
Bold Words in bold show items to select, click, or press,
such as menu items, buttons, or keys on the keyboard.
Note This symbol means the following information is a note
that gives you important information that may affect
how you use Core:Tx.
Caution This symbol means the following information is a
caution that warns you about actions that may delete
data from your computer.

Figure 1: Package contents
Base Station
The base station connects to your personal computer or laptop
using the provided USB cable. It collects information from the
Core:Tx transceiver and communicates to your computer.
The base station has the following key parts, as shown in Figure 2:
• Two lights—show that the base station has power and that it
has a connection to the transceiver.
• USB cable port—where you connect the provided USB cable
into the base station.

Transceiver
Position the transceiver on the patient before the patient starts an
exercise. The transceiver has the following key parts, as shown in
Figure 3:
• Orange button—press to turn on the transceiver and interact
with the Core:Tx software.
• Light—shows communication to the base station, as well as
showing that the batteries are low on power.
• Axis knobs—show the Core:Tx axis. The knobs represent the
axis of motion the transceiver is able to detect. This gives you a
visual reference for proper alignment of the transceiver.
• Battery door—on the underside of the transceiver where you
install the batteries. For more information, see “Inserting the
Batteries into the Transceiver” on page 8.

Note
The transceiver automatically turns off after three minutes
of inactivity. This feature helps save battery power.

Straps
Core:Tx comes with a total of six straps and one strap extension.
There are three main styles, with one strap provided in four color-
coded sizes. Refer to the color tab on each strap to differentiate it
from others. Use the strap extension to make a strap longer. You
may need to use the extension when attaching the strap to pieces of
equipment, such as a foam roller.
Use the straps to attach the transceiver to various locations on the
body for specific exercises. To learn how to use the straps, see
“Positioning the Transceiver” on page 40. The exercise section
shows the proper transceiver location for each exercise. For more
information, see “Chapter 7, Lumbar Stabilization in Sitting
Position on Therapy Ball” on page 59.
The straps have the following key parts, as shown in Figure 4:
• Hook and loop strips—adheres to the other part of the strap to
secure it during exercises.
• D-ring—loop the strap through to secure it.
• Elastic bands—where you place and secure the transceiver.

Care and Storage
• Do not drop or subject the transceiver to strong mechanical
shock.
• Do not dismantle or modify the transceiver or base station.
• Do not immerse the base station or transceiver in water or
other liquid.
• Changes or modifications to Core:Tx equipment not expressly
approved by Performance Health Technologies could void your
authority to operate this equipment, as granted by the Federal
Communications Commission (FCC).
To clean:
• Straps—When necessary, wipe down the back of the strap with
mild detergent and hang dry. Hand wash entire strap in mild
detergent if necessary. Do not use solvents to clean the straps.
