2Introduction
2.1 Brief Description:
Noraxon’s Ultium Motion 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 segment.
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 joint articulations.
The Ultium Motion sensors transmit the motion of the human body directly to the Ultium receiver to
quantify the angular changes of the selected body segments. The captured data may then be analyzed
using Noraxon MR3 software.
The main advantage of this technology is that 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
Ultium Motion system without the traditional laboratory-based measurement limitations.
Ultium Motion complies with all applicable safety and performance standards for electronic devices.
Further, the Ultium Motion System has been designed and tested to operate in a compatible manner
with other devices in a medical care setting.
2.2 Device Safety Categories
The Ultium System incorporates the following ratings:
Class II (double insulation) for electrical safety with internal battery power during operation
CISPR 11 Class A radio frequency compatibility (ref. Section 17 for details)
Note: The EMISSIONS characteristics of this equipment make it suitable for use in industrial areas and
hospitals (CISPR 11 class A). If it is used in a residential environment (for which CISPR 11 class B is
normally required) this equipment might not offer adequate protection to radio-frequency
communication services. The user might need to take mitigation measures, such as relocating or re-
orienting the equipment.
2.3 Intended Use
Noraxon’s 3D Ultium Motion system is intended to measure and quantify angular changes of selected
body segments. These measurements can provide data to assist in understanding movement
abnormalities. The system is designed as a biofeedback tool for clinical, investigational and research
applications.
Intended Users
Researchers or individuals trained in physical medicine, physical therapy, human performance or
ergonomics and who have gained familiarity with the Ultium System and its software.
Subject Populations –Medical
Individuals with neurological disorders, physical injuries, pre/post-surgical or post stroke conditions.

(Rev B)
Subject Populations –Non-medical
Athletes, workers at their work site, subjects in new product trials.
Common Applications
Gait analysis; identification of inconsistencies and abnormalities; tracking over time the outcome of
surgical, therapeutic or orthotic interventions; identification of ergonomic stress factors in the
workplace or new product designs.
Suitable Environments
The Ultium System is suitable for use in hospitals, clinics, academic laboratories except near active HF
SURGICAL EQUIPMENT or MRI IMAGING EQUIPMENT.
Expected (Essential) Performance
The Ultium Motion System (Sensor & Receiver) synchronously acquires and displays motion signals
from joint segments in real time.
Consideration should be given to common place wireless networks that may be present in the
environment. Under the conditions of excessive wireless communications performance of the Ultium
System may exhibit sluggish (non-real-time) behavior.
Risk-Benefit
There is no identified risk of physical harm or injury with use of the Ultium product. The benefit
provided by use of the device is the provision of objective measures to assess the severity of
pathological human movement conditions and gauge any subsequent improvement offered by therapy,
training or design changes.
Special Concerns
The Ultium Motion system operates by means of microwave radio frequency transmissions. Certain
(older, vintage model) pacemaker devices may be susceptible to such microwave transmissions.
Therefore, use of the device is contra-indicated in individuals who have implanted pacemakers.
2.4 Contraindications
Use of the Ultium Motion System is contra-indicated in individuals who have implanted pacemakers.

Ultium Receiver –A USB-connected Receiver which receives signals from one or more Ultium Motion
Sensors.
Ultium Motion Sensor –A small individual radio transmitter typically worn on the body used to
measure and transmit motion related signals (such as position, orientation, or acceleration). The Ultium
System can accommodate up to 16 body worn Ultium Motion Sensors in one network.
Ultium Motion Serial Number –A unique five-character tag used to identify each Ultium Motion Sensor.
The members of any Ultium network are determined by their serial numbers.
RF –(Abbreviation for Radio Frequency) Wireless communication takes place on assigned radio
frequencies or channels. For the Ultium 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 Network –RF transmissions for the Ultium System can be selected to occur on one of 4 different
networks. All networks use frequency hopping to avoid interference.
RF Traffic –The presence of radioactivity present on a given frequency like the number of cars on an
expressway. Several users (wireless devices) may be communicating using the same frequencies. Best
operation of the Ultium System occurs when the RF Traffic is low.

6Basic Operation Instructions
6.1 Safety Information Summary
Strictly follow all safety practices given in Section 1 of this manual. The most critical safety practices
are repeated here.
•Never use the Ultium System on a person with an implanted pacemaker
•Never operate the Ultium System within 1 meter of any critical medical
device
6.2 Ensure the Ultium Sensor is in Measurement Mode
Check the Sensor Status LED
The sensor’s STATUS indicator provides a means of communicating its operational state. In the idle
state, the STATUS indicator will flash blue. When the sensor is actively measuring, the STATUS indicator
will flash green.
If the STATUS indicator is not flashing at all, the Ultium Motion Sensor may be powered off or may have
a depleted sensor battery.
6.3 Determining Sensor Assignments
Before performing a recording, decide which body segments will be included in the recording. Sensor
configuration best practices are listed below.
Note: A full-body recording does not need to be used every time. Additionally, if you have purchased a
partial body set of sensors, you can re-assign sensors to be used for different body segments. Refer to
Section 5.6 for instructions to reassign sensors to different body segments.
Using Object Sensors
Any Ultium Motion Sensor may be used as an object sensor. There is no limit to the number of sensors
that can be used as object sensors. These object sensors are assigned to the hardware configuration
using the sensor’s serial number. For more information on object sensors, refer to Section 7.3.
CAUTION

Ultium Motion Hardware User Manual
20
(Rev B)
Sensor Configuration Best Practices
•For anatomical angles to be calculated, at least two sensors need to be located around a joint.
For example, for the software to calculate elbow angles, the upper arm and lower arm sensors
for the corresponding arm must be used in the configuration.
•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.
•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 relative to the bone (s).
•If the Pelvic or Upper Thoracic sensors are not used, each sensor must be positioned in-line
with the long axis of the bone segment.
•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. However, contralateral sensors
should be placed at equal distance from the joint center.
6.4 Attaching the Sensors
Sensor Attachment
The sensors can be attached with special fixation straps. These straps are designed for clinical use
and slow, not highly dynamic, movements. For sports activities or impact related movements, we
recommend additional fixation of the sensors with the use of elastic self-adhesive tape.
•Pelvis & Lower Thoracic –elastic belt or double-sided tape with torso adapter
•Extremities & Head –elastic strap
•Hands –hand straps
•Feet –shoe adapter
•Upper Thoracic –double-sided tape with torso adapter
Sensor Placement
Sensor Placement Orientation:
•Sensors must be placed so the status LED is facing away from the subject.
•The positive X-coordinate on the sensor label should have a superior orientation (i.e. up to the
sky/ceiling) for the trunk, head, and pelvis. The limb segments sensors should have the
positive X-coordinate in line with a proximal orientation (i.e. towards the proximal joint along
the long axis of the bone segment).
Note: The X-coordinate points distally (toward the toes) for the feet sensors.
Sensor Placement Assumptions for the Ultium Motion System:
•Place sensors symmetrically between each sides of the body.
•Pay careful attention to attachment of the pelvic sensor. Any dislocation between the pelvic
sensor and pelvic bone will influence the accuracy and validity of all angular calculations.
