EMG (Electromyography)

>Two / Four channel acquisition.
>Large amount of data storage which can be
replayed with audio.
>Easy to choose muscle from a well organized list for testing and scoring. Scoring options are user
definable.
>Continuous/Rasterized display.
>Surface EMG, SP Activity, Interference Pattern, Triggered EMG, Single Motor Unit Potential, Turn/Amplitude analysis can be done on a single
screen.
>Advanced quantitative EMG for classifying MUPs into different bins depending upon morphology.
>Manual/ Auto MUPs selection for analysis.
>Guide for commonly used muscles describing its location and needle insertion positions.
NCS (Nerve Conduction Studies)
>Auto Latency/Amplitude marking with user
definable measurements.
>Separate test customization for each Nerve.
>More than one nerve can be tested on a single screen.
>Individual sweep and sensitivity for each trace which is adjustable even after acquisition.
>Direct dragging of markers and traces with mouse.
>Motor and sensory tests can be done on the same screen. F latencies can be marked while doing MNC test its self.
>Multiple sets for recording RNS/ Decrement waves.
>Definable number of traces in all tests.
>Split Screen for viewing Ipsi and Contra recordings in Blink Reflex test.
>Built in wizard for help on electrode placements and stimulus sites for various nerves.
>Fully isolated shock stimulator and amplifiers for patient safety.

EPs (Evoked Potentials)
>Up to 16 waves can be recorded.
>Left/Right sides can be compared on single screen.
>Double buffered (odd/even) averaging technique.
>Both odd/even or normalized average can be viewed.
>User definable marks which gets auto marked on the wave.
SEP, VEP, BERA, 40 Hz
>Auto Protocol with user defined intensities is provided for fast Hearing Threshold
measurements along with Latency-Intensitiy
graph.
>Guide detailed for showing various electrode placements in all EPs along with expected waveforms.
