Noraxon U.S.A, Inc. MyoMOTION SystemP-6828 Rev A (Oct 2014) 1Section 1: IntroductionBrief DescriptionNoraxon’s myoMOTION™ System is a combination of hardware and software that enables thecapture of human motion in three degrees of freedom (3 DOF). A compact Inertial MeasurementUnit (IMU) placed on any segment of the body precisely tracks the 3D angular orientation of thatbody section. By positioning individual IMU sensors on two contiguous body segments, theintervening joint Range of Motion (ROM) can be determined. This concept is easily expandablefrom a single joint of interest to a simultaneous 16 sensor full body measurement across all majorarticulations.The myoMOTION sensors transmit the motion of the human body directly to the myoMOTIONreceiver or data logger to quantify the angular changes of the selected body segments. Thecaptured 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 beused with independent external cameras. This unique concept gives the user flexibility to operatethe myoMOTION system without limitations.The myoMOTION data logger brings even more portability to the system. With the myoMOTIONdata logger, users can apply the sensors and, using the data logger, record data anywhere duringany activity. This recorded data can then be imported from the data logger into the software forprocessing and analysis.Intended UseNoraxon’s 3-D myoMOTION system is intended to measure and quantify angular changes ofselected body segments. The data logger is used to make the system truly portable by offering anoption for recording data without the use of a myoMOTION receiver or a computer. Recordeddata can then be imported into the software for data analysis and reporting.Intended UsersResearchers and individuals trained in physical medicine, physical therapy or ergonomicsSubject Populations – MedicalIndividuals with cerebral palsy, physical injuries, post-surgical or post stroke conditionsSubject Populations – Non medicalAthletes, workers at their worksite, subjects in new product trialsCommon ApplicationsMovement Technique analysis, gait analysis; tracking over time the outcome of surgical,therapeutic or orthotic interventions; identification of ergonomic stress factors in the workplace ornew product designs; sports performance analysis, and postural assessment.ContraindicationsUse of the myoMOTION analysis system and data logger is contra-indicated in individuals whohave implanted pacemakers.
