Quick Examination Innovative hardware and software shorten Low noise, compact amplifier The low noise amplifier speeds up the examination by giving you clean waveforms easily and quickly. You can optionally configure it with amplifiers from 2 channel (JB-942BK) or 4 channel (JB-944BK). Impedance check Needle electrode holder Median nerve inching measurement with low noise amplifier. User-friendly control panel The simple and easy-to-use control panel allows smooth examination. You can change the electric stimulation duration and rate with easy, one-touch operation. Select the measurement side...

User-friendly operation menu You can arrange the settings of the Quick menu window according to your own operation procedure. You can directly open the examination program, saved data, edit program, operation manual and examination guide from the Quick menu. Extensive built-in help The Neuropack Navigator on-screen examination guide shows examination information, electrode, stimulation positions for NCS and other examinations. Onscreen operation manuals are also available. You can refer to Neuropack Navigator and operation manuals anytime. Innovative software Quick EMG and Quick NCS programs...

EMG Routine EMG Examination Program, EMG2 EMG2 is the first routine program to utilize auto MUP detection and classification, and real time turns/amp analysis. A more functional and sophisticated EMG findings screen in EMG2 meets various needs in clinical use by easy and smooth operation. Quick Operation The Muscle List appears when the program starts. Main muscles are displayed in the Quick List box and you can select the muscle by clicking or pressing the number on the left side of the box with the number key. Quick Display You can easily choose from 4 measurement modes - Insertion, Spontaneous,...

Interference Turns/amp measurement is automatically performed in Interference mode. The measurement result at every one second is displayed on the Turns-interval histogram, turns/amp histogram and turns/amp graph. Interference window The turns/amp normative data of Biceps Brachii, Extensor Digitorum Communis, Quadriceps and Tibialis Anteriar muscle are installed as default settings and its normative area is displayed in the turns/amp histogram. You can easily recognize whether or not the measuring waveforms are in the normative range. Normative data area Amp/Turn histogram Amp/Turn graph Turns-Interval...

EMG Routine EMG Examination Program Up to 99 sites of continuous 600 second EMG waveforms can be stored on the hard disk and reviewed. Quick MUP analysis, muscle and site selection, and smooth scroll help in the diagnosis of needle EMG study. Quick MUP analysis Up to 4 selected MUP waveforms are shown in the manual MUP window with the automatically calculated data (duration, amplitude, phase, turns, area and rise time). Quick muscle and site selection You can easily choose the muscle and site from the muscle quick list with the SIDE/SET key and MUSCLE/TEST key on the operation panel. Smooth scroll...

Quantitative EMG Software (QP-946BK) (Option) • QEMG ♦ Real-time MUAP analysis With the template matching method, MUAP are automatically classified into several patterns and the amplitude, phase, turns, area, rise time and firing rate are quantitatively analyzed in realtime. There are two methods of analysis: triggered and continuous. The analysis results can be statistically processed. ♦ Real-time interference pattern analysis Interference patterns can be analyzed in two ways: turns/amp analysis and power spectrum analysis with FFT. Single Fiber and Macro EMG Software (QP-947BK) (Option) Realtime...

NCS NCS program for the ultimate timesaving exam The NCS program lets you perform MCS, SCS and F wave in one program. Up to 42 examinations can be created in your own custom routine protocol by selecting nerve, site and exam. You can change the examination by just clicking the item in the list box. The results of all examinations you performed in the NCS program are compiled in one Microsoft Excel report so you don’t have to make separate reports for each examination. User definable trace annotation Site comments are simultaneously entered in the table and marked on the waveform. Normative latency...

SEP Standard Examination Protocols • • • • • SEP SSEP ECG-SSEP ESCP Electric ♦ ECG artifact-free SSEP With ECG-SSEP protocol, stimulation and averaging is done during the flat period of the ECG waveform so artifact-free waveforms can be recorded. SSEP screen ♦ Signal triggering and back averaging Cortical potentials prior to muscle contraction can be recorded by using a rectified EMG signal trigger and back averaging. ♦ Simultaneous SSEP and SEP measurement Upper and lower extremity measurements can be conducted at the same time on the same screen. SEP/SSEP screen Pattern-VEP Goggle-VEP Flash-VEP...

ABR Standard Examination Protocols • • • • • ♦ 3 types of auditory stimulation Click, tone burst, and tone pip stimulation are available. ♦ ABR auto marking In the ABR protocol, automatic waveform marking allows time saving measurement of latency, amplitude, and interval. ♦ Automatic separation of AP and CM waveforms In EcochG examination, AP and CM can be automatically separated from the original waveforms in real time. The original, AP and CM waveforms are simultaneously displayed on the screen. ♦ Simultaneous ABR and MLR measurement ABR and MLR can be measured simultaneously on the same screen....
