Noraxon U.S.A, Inc.DTS EMG SensorSection 1: IntroductionBrief DescriptionThe TeleMyo Direct Transmission System for EMG and other biomechanical sensors directlytransmits data from the electrode or sensor site to a Receiver.This direct transmission concept greatly simplifies the arrangement of EMG measurements byeliminating cable connections between the EMG electrodes and EMG amplifier. The small,lightweight probes are also beneficial for small subjects like children and small animals.This unique concept gives the user the flexibility to operate the DTS system without limitations.The Telemyo DTS system is designed to operate any configuration between 4 and 16 channels.Intended UseThe DTS EMG sensor is intended to measure and quantify muscle biopotential signals separatelyor in combination with other kinematic or kinetic signals. This information can be used to affectmuscle training and reeducation.Intended UsersResearchers or 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 ApplicationsGait analysis; tracking over time the outcome of surgical, therapeutic or orthotic interventions;identification of ergonomic stress factors in the workplace or new product designsContraindicationsUse of the DTS EMG sensor is contra-indicated in individuals who have implanted pacemakers.P-5428/5468 Rev A (Dec 2013)1

Noraxon U.S.A., Inc.DTS EMG SensorGlossary of TermsDTS – (Abbreviation for Direct Transmission System) A network of short-range wireless sensorswhere measured data is transmitted directly from each sensor into a receiver for subsequentdisplay and analysis on a computer or intelligent handheld device.DTS Sensor -- A small individual radio transmitter typically worn on the body used to measureand transmit bio-potential signals (such as EMG) or motion related signals (such as position oracceleration).DTS Sensor Type – Refers to different models of DTS Sensors. Each sensor model measures agiven type of physical parameter. Different DTS Sensor Types can be combined in the same DTSnetwork. The most common DTS Sensor Type is EMG. Examples of other types includeAccelerometers, Goniometers and Force sensors.DTS Serial Number – A unique four-character tag used to identify each DTS Sensor. Themembers of any DTS network are determined by their serial numbers. Also DTS Sensor Typesare grouped into a predefined range of serial numbers. Thus by serial number the DTS systemcan automatically determine the type of signal parameter being transmitted from any DTS Sensorin the network.Probe – A generic term for any DTS Sensor.RF – (Abbreviation for Radio Frequency) Wireless communication takes place on assigned radiofrequencies or channels. For the Noraxon DTS System, RF transmissions occur at frequenciesbetween 2.4 GHz and 2.5 GHz. Other wireless systems including WiFi and Bluetooth commonlyoperate at the same frequencies and can be a source of interference.RF Channel – RF transmissions for the DTS System can be selected to occur on one of 24different radio frequencies. The ability to operate over several different frequencies allows theDTS 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 ofcars on an expressway. Several users (wireless devices) may be communicating using the samefrequency. Best operation of the DTS System occurs when the RF Traffic is low (no other users)on the selected RF Channel.Sensor Delay – The sensor delay used when retransmitting data from the sensor to the receiver.P-5428/5468 Rev A (Dec 2013)3

Noraxon U.S.A., Inc.DTS EMG SensorSection 4: General Warnings and CautionsRisks and BenefitsThere is no identified risk of physical harm or injury with use of the DTS EMG sensor. Thebenefit provided by use of the device is the provision of objective measures to assess the severityof pathological human movement conditions and gauge any subsequent improvement offered bytherapy, training, prosthetic alterations or ergonomic design changes.Safety Information SummaryCautions Never use the DTS EMG Sensor on a person with an implanted pacemakerNever operate the DTS EMG Sensor within 1 meter of any critical medical deviceWarnings Do not immerse the DTS Sensors in any water or liquidDo not use the Noraxon DTS system on individuals undergoing MRI, Electro Surgery orDefibrillationThe DTS EMG sensor produces results that are informative, not diagnostic. Qualifiedindividuals must interpret the resultsAttention The operator must be familiar with typical characteristics of the signals acquired by theTeleMyo DTS equipment and be able to detect anomalies that could interfere with properinterpretation.P-5428/5468 Rev A (Dec 2013)5
