42The MP System offers many options for recording surface,needle and fine wire EMG. Record and analyze generalmuscle strength and fatigue or muscle twitch data froma variety of body locations. Alternatively, combine EMGrecording channels with other data channels to displaymuscle contraction simultaneously with other physiologicalevents. Integrate and/or filter raw EMG data duringrecording for immediate analysis. Correlate muscleactivity with data from other sources, such as forceplates, goniometers, and motion analysis equipment.Spike counting and frequency analysis tools are availablefor post-acquisition analysis.Features• Median & Mean Frequency Analysis• EMG Power Spectrum Analysis• Integrated (RMS) EMG• EMG & Force• Active Electrodes & Fine Wire EMG• Automatic Spike Counting & Analysis• Histogram Analysis• Facial EMG & Startle Response• Interface with Imaging Equipment• Single-fiber EMG• Motor Unit Action PotentialSee also — Remote Monitoring (page 46) and Biomechanics(page 44) applicationsEMGMedian & Mean FrequencyAnalysisAnalysis of EMG signals in the frequency domain canprovide useful insight into the nature of the EMG data.The frequency spectrum data may be used to generateother measures associated with EMG frequency analysis.Select an area of EMG data and use the Fast FourierTransform function to perform a linear magnitude FFTon the selected data, then integrate the result todetermine the median and mean frequency.AcqKnowledge can be used to calculate these parametersafter the EMG data has been collected.EMG Power Spectrum AnalysisA common tool for investigating the EMG is the PowerSpectrum Density (PSD). Use AcqKnowledge tocompare responses from one part of the recording tothe next. Calculate the PSD by squaring the linearFFT magnitude.Integrated (RMS) EMG Q40Calculate the integrated EMG envelope on- and off-line.The integration function incorporates an RMS (RootMean Square) feature set to operate over a user-specified
number of samples. Adjust the RMS time constant byincreasing or decreasing the number of samples used toperform the integration. The number of samples used inthe RMS integration divided by the sample rate isproportional to the time constant of the integration.EMG and Force Q41For in-depth studies of muscle work and fatigue, use theEMG100C amplifier with a hand dynamometer(TSD121C). The software will display the forcemeasurements (calibrated in pounds or kilograms) aswell as the raw and integrated EMG data. It’s possible tosimultaneously measure EMG with signals from forceplates, load cells, and pressure transducers.Active Electrodes &Fine Wire EMGThe TSD150 Series of active electrodes interface withthe HLT100C High Level Transducer interface module.The TSD150 electrodes have built-in amplification,which allows the subject to be a greater distance fromthe recording equipment. The TSD150 will record bothsurface and fine wire EMG. The transducers are easilyadapted to fine wire recording by unscrewing the surfaceelectrode pads and attaching spring clamps (includedwith each TSD150).Automatic Spike CountingThe Peak Detection features let users automatically analyzeraw EMG spike data. Selectthe desired measurements andthe software will calculate thevalues for each spike in thedata file or within a selectedarea. This analysis can also beperformed over pre-definedtime intervals—enter a timeinterval and the software will runthrough the file, analyze the data, and enter the resultsinto a Journal file and display the data as a new channel.• Max• Min• Pk-Pk amplitudes• Pk-Pk frequencyHistogram AnalysisUse the Histogram display features to identify trendswithin the EMG data. Select an area of data, or the entiredata file, and the Histogram feature will bin the valuesinto their appropriate amplitude ranges. The softwarewill automatically determine the display range and thenumber of bins, or you can set them manually.Histogramming highlights differences in the EMG whenthe muscle is under a variety of loads and conditions.Facial EMG & Startle Response Q11Use the STM100C stimulator and the MP SystemControl channels to perform multiple stimulusparadigms. Present a pre-defined auditory stimulus orstimulate the subject based on the result of a physiologicalresponse. Use the EMG amplifier to record facial EMG(eyeblinks) and set the software to integrate the signalon-line. Calculate the time and amplitude of theresponse using the measurement tools. Automate analysiswith the Peak Detection features and display the resultsas a new channel.Interface with Imaging EquipmentThe MP System can be synchronized with imaging systems(MRI, video capture, etc.). An imaging system can beused to trigger the recording or, alternatively, the MPSystem can be used to trigger the imager.Single-fiber EMGRecord and analyze single-fiber potentials with aconcentric needle electrode (EL451). Set theEMG100C to a 100 Hz - 5 kHz recording bandwidth. Forimproved rejection of low frequency background activityof distant fibers, run the data through a real-time 500 HzHP filter in AcqKnowledge.Motor Unit Action PotentialThe motor unit action potentials (MUPs) are thesummation of all single-fiber potentials innervated.Evaluate waveshapes of MUPs and measure amplitude,rise time and duration using the EMG100C withconcentric needle electrodes (EL451).HardwareOptions:43EMG100C 57ElectromyogramAmplifierDA100C 54General-purposeTransducer AmplifierTSD121C 74General-purpose HandDynamometerTSD130Series 76GoniometersHLT100C 53High Level TransducerModuleINISO 53Input Signal IsolatedAdapterOUTISO 53Output SignalIsolated AdapterTSD109Series 71Tri-axialAccelerometersTSD111 71Heel/Toe StrikeTransducerTSD150 80Active ElectrodesSTM100C 64Stimulator ModuleSTMISOSeries 64Electrical StimulusIsolation AccessoriesTEL100C 66Remote MonitoringModule SetEL Series 83ElectrodesLEAD Series 83Electrode LeadsMEC Series 87Module ExtensionCables
