Section 1: Introduction

BriefDescription
Noraxon’s myoMOTION™ System is a combination of hardware and software that enables the
capture of human motion in three degrees of freedom (3 DOF). A compact Inertial Measurement
Unit (IMU) placed on any segment of the body precisely tracks the 3D angular orientation of that
body section. By positioning individual IMU sensors on two contiguous body segments, the
intervening joint Range of Motion (ROM) can be determined. This concept is easily expandable
from a single joint of interest to a simultaneous 16 sensor full body measurement across all major
articulations.
The myoMOTION sensors transmit the motion of the human body directly to the myoMOTION
receiver or data logger to quantify the angular changes of the selected body segments. The
captured data may then be analyzed using Noraxon software.
The main advantage of this technology is it is easy and quick to use, fully portable and can be
used with independent external cameras. This unique concept gives the user flexibility to operate
the myoMOTION system without limitations.
The myoMOTION data logger brings even more portability to the system. With the myoMOTION
data logger, users can apply the sensors and, using the data logger, record data anywhere during
any activity. This recorded data can then be imported from the data logger into the software for
processing and analysis.

IntendedUse
Noraxon’s 3-D myoMOTION system is intended to measure and quantify angular changes of
selected body segments. The data logger is used to make the system truly portable by offering an
option for recording data without the use of a myoMOTION receiver or a computer. Recorded
data can then be imported into the software for data analysis and reporting.
Intended Users
Researchers and individuals trained in physical medicine, physical therapy or ergonomics
Subject Populations – Medical
Individuals with cerebral palsy, physical injuries, post-surgical or post stroke conditions
Subject Populations – Non medical
Athletes, workers at their worksite, subjects in new product trials
Common Applications
Movement Technique analysis, gait analysis; tracking over time the outcome of surgical,
therapeutic or orthotic interventions; identification of ergonomic stress factors in the workplace or
new product designs; sports performance analysis, and postural assessment.

Contraindications
Use of the myoMOTION analysis system and data logger is contra-indicated in individuals who
have implanted pacemakers.

GlossaryofTerms
myoMOTION Sensor -- A small individual radio transmitter typically worn on the body used to
measure and transmit motion related signals. The myoMOTION System can accommodate up to
8 body worn myoMOTION Sensors on one receiver, or can be configured with two receivers for
up to 16 sensors.
myoMOTION Serial Number – A unique four-character tag used to identify each myoMOTION
Sensor. The members of any myoMOTION network are determined by their serial numbers.
RF – (Abbreviation for Radio Frequency) Wireless communication takes place on assigned radio
frequencies or channels. For the myoMOTION System, RF transmissions occur at frequencies
between 2.4 GHz and 2.5 GHz. Other wireless systems including WiFi and Bluetooth commonly
operate at the same frequencies and can be a source of interference.
RF Channel – RF transmissions for the myoMOTION System can be selected to occur on one of
24 different radio frequencies. The ability to operate over several different frequencies allows the
myoMOTION System to reposition its radio operation if needed to avoid interference.
RF Traffic – The presence of radioactivity present on a given frequency similar to the number of
cars on an expressway. Several users (wireless devices) may be communicating using the same
frequency. Best operation of the myoMOTION System occurs when the RF Traffic is low (no
other users) on the selected RF Channel.
Serial Number – A unique four-character tag used to identify the myoMOTION Data Logger.

Section 5: Getting Started

QuickStartGuide
To begin using the Data Logger, the user must charge the device using the USB A to mini-B
cable provided with the data logger. Once charged, it is necessary to setup the sensors, time and
date before a measurement can be taken.
Note: It is important to press the Save button after each step to ensure the data logger stores
the changes and it will work properly.
For the initial setup: turn the Data Logger on and Press OK to enter the Setup screen.
1. Setup Sensors
Assign Sensors
Enter the serial number of each sensor into the body
segment it will be attached to. This is also where the
footswitch sensors will be entered, if they are going to
be used.
Enable Sensors
Selects which sensors will be used in the recording
by selecting “ON”. Any sensors not enabled
(switched “OFF”) will not have any data recorded.
Note: Any sensors mistakenly enabled but not being used,
will either create an inaccurate record or give an error if the
data logger is not able to communicate with the sensor.
Footswitches
Adjust the sensitivity of the footswitches
Configuration
a. RF Channel – the radio frequency (RF)
channel can be set to anything from A to F.
This determines the frequency at which the
sensors will communicate with the data
logger.
b. Sample Rate – the sample rate can be set to
100 or 200Hz.
c. Enable Accel – turns acceleration on and off
Note: Research myoMOTION can measure 16 sensors at
100Hz with acceleration enabled, or 8 sensors at 200Hz
with acceleration enabled. Clinical myoMOTION can only
sample at 100Hz and does not have acceleration
capabilities.

2. Set Time
Set the time and press Save.
Note: If no time is set, the data logger will default to 1:00
a.m.
3. Set Date
Set the date and press Save.
Note: If no date is set, the data logger will default to
January 1, 21013.
Note: After the initial setup, the first 3 steps may be skipped, and only the following steps are
necessary to record a measurement.
4. Take a measurement: turn the Data Logger on and Press OK to enter Setup
Apply Sensors
Put sensors on the body segments to be used in the
measurement.
Check Settings
Enable the sensors that will be used and disable the
sensors that will not be used.
Make sure the configuration settings are correct.
Start Measurement
Highlight the State Measurement option and press
OK; this will take the user to the calibration screen.
Select Calibration Position
There are 3 calibration positions available, illustrated
by the image on the screen:
a. Standing straight
b. Standing with arms flexed 90°
c. Sitting with arms and legs flexed 90°
Calibrate
Once the calibration position is selected, press OK
and the calibration countdown will begin.
The calibration will give the user either 20 seconds
(the first calibration) or 5 seconds to get into the
calibration pose before calibration will begin.
The data logger will also have an audio countdown
and beep at the user every second until calibration is
complete.

Any sensor configuration is supported; even single sensor or two distant
sensor measures (left and right foot only) are possible. But we recommend
whenever possible to start with the Pelvic or Upper thoracic sensor and
create uninterrupted sensor chains to distal segments.
Note: anatomical angles can only be calculated if at least two sensors are
located around the joint.
If the Pelvic or Upper thoracic sensors are available, any distal sensor
can be mounted to any position of the selected segment. We recommend
positions that best follow the bone movement and are not too much
influenced by muscle belly movements. Whenever possible the sensors
should have sticky skin contact and not move against the bone (s).
If Pelvic or Upper Thoracic sensors are not used,
it is needed to exactly position extremity sensors
lateral and orientation to the underlying bone
axis.
Please also note that the distance of a given
sensor to the joint center does not influence the
angular calculations in both of the above
mentioned modes.
Calibration of myoMOTION sensors
The calibration procedure defines the 0° point or 90° point (dependent of calibration position) of the
angular displacement that is measured by each myoMOTION sensor. Any calibration position should be
arranged as accurate as possible. For example, if in standing straight position the knee joint cannot be
brought to the neutral zero joint position; there will be an angle offset error in each angle measured later
on.
The calibration position needs to be kept until the audio cues indicate the calibration is complete.
Cal-Position
Standing straight:
All joints are in
„neutral“ zero
position, thumbs in
view direction
Cal-Position Standing

As above, but elbow is


DeviceCommunication(Driver)SoftwareInstallation
No driver installation is needed. The myoMOTION Data Logger uses a G2 driver for
communication over the USB port.

CompanionSoftwareInstallation
The myoMOTION System is compatible with the Noraxon MR3 software program. To install MR3
follow the appropriate instructions given below:
MR3Installation
1. Insert the MR3 Software CD into the PC
2. A menu will automatically pop up
3. Click on “Install MR3” and follow the Wizard’s instructions
4. A new icon will appear on your desktop. Double click on the icon to start
the MR3 software.
SoftwareConfiguration

To analyze the myoMOTION Data Logger data, the data must first be imported into the database.
To do this, connect the myoMOTION Data Logger to the PC via USB cable. Open the MR3
software and click on the Database tab.
Open the Project and Subject the data will be imported into. Then, under the “Import” options,
select the “Import record from MyoMotion DataLogger (*.mml) and find the directory to the Data
Logger.

Section 7: Pre-Use Check-Out

NormalAppearanceofSignals
The sensor’s green STATUS indicator provides a means of communicating its operational state.
In the idle state, the STATUS indicator will flash at a low, once per second rate. When the sensor
is actively measuring a signal, the STATUS indicator will flash recognizably faster.
If the STATUS indicator is not flashing at all, the myoMOTION Sensor must be placed in a
powered charger station to be reactivated. This could be due to a depleted sensor battery or if the
sensor has been deliberately placed in a special shut down mode.

AttachingthemyoMOTIONSensortoaPatientorSubject
For proper operation the myoMOTION Sensor must be applied firmly to the body in the correct
orientation. Care should be taken to make sure the sensor rotates with the limb to which it is
attached. Each sensor has a label indicating the X, Y and Z –axis in the lower right hand corner of
the sensor. Generally all sensors are positioned so that in normal standing position the sensor is
in line with the side of the body (upper extremities) or the front of the body (lower extremities) and
the X-axis vector on the sensor label is pointing vertically up. The only exception to this is the foot
sensor; here the X-axis vector is pointing toward the toes.
Note: When no pelvis sensor is included in the system, extra care needs to be taken to ensure
that the sensors are in line with the underlying bone segment and pointing in the correct direction.
When the pelvic sensor is used, an exact sensor positioning is not required; the accuracy of the
sensor is not affected by a slight variance.
The myoMOTION Sensors can be secured in place using Noraxon supplied double-sided
adhesive tape, clips and/or elastic straps. Straps are recommended if dynamic movements are
expected.
Calibration
Instruct the subject to assume the selected starting position (calibration pose): Standing straight,
Standing arms flexed 90°, or Sitting with arms and legs flexed 90°. During calibration, the sensors
are compared to the known starting position of all the body joints. When ready, the user will hit
the Calibration button to begin. The Data Logger will indicate the start of the countdown to
calibration by a visual countdown on the display screen as well as an audible tone every second
of the countdown until calibration has ended at 0 seconds.

Section 8: Operating Instructions

SafetyInformationSummary
Strictly follow all safety practices given in section 4 of this manual. The most critical ones are
repeated here.
CAUTIONS

Never use the myoMOTION System on a person with an implanted pacemaker
Never operate the myoMOTION System within 1 meter of any critical medical device
NormalFunctionswithInterfacetoaPC
When a record is imported and used with the companion software the myoMOTION System
displays the selected anatomical angles, orientation angles and a skeleton avatar that reflects the
movement of the subject in the myoMOTION Data Logger record.
Consult the user manual for the companion software for descriptions of the setup, playback and
analysis of the data acquired by the myoMOTION system.
SecondaryFunctionswithoutPCInterface
The myoMOTION data logger (part #682) allows the user to travel with the moyMOTION sensors
and portably record their data away from the PC. Recorded data can later be accessed with the
use of a PC and Noraxon’s MR3 software.

ExceptionalFunctions/Situations(errormessages)
Error Message Meaning
Too many sensors
Too many sensors have been enabled or the
sample rate is set too high. The data logger will
support 16 sensors and 2 footswitches at
200Hz sample rate or 8 sensors at 200Hz
sample rate with acceleration enabled
Clinical sensors do not support
acceleration
Clinical sensors do not support acceleration for
clinical sensors. Acceleration needs to be
disabled in order for the data logger to work
with clinical sensors.
Clinical sensors only support 100Hz
sample rate
Clinical sensors do not support 200Hz sample
rate. Sample rate must be changed to 100Hz.
No sensors enabled
Sensors may have been assigned, but they
have not been enabled. Sensors must be
turned on in order to record data.
The following sensors are not responding:
XXXX
The sensors listed are not communicating with
the data logger (XXXX represents the serial
number of the sensors not communicating)
Sensor firmware must be > version X for
sensors
The sensors’ firmware needs to be updated to
a certain version to work with the data logger
