Portable excellence

Neuro-MEP-Micro-V, despite its compact design, allows performing almost all EMG, NCS and EP tests on one dedicated platform for clinical assessments and experimental research:

· NCS – Nerve Conduction Studies:  Motor and sensory conduction velocity, F-wave, H-reflex, motor and sensory inching.

· EMG – Electromyography:  Spontaneous activity, interference curve, motor unit potentials (MUP), macro EMG.

· Neuromuscular junction testing:  Repetitive stimulation, jitter.

· Motor Unit Number Estimation (MUNE).   

· Additional EMG tests:  Blink reflex, sacral reflex, bulbocavernosus reflex, Т-reflex (with optional tendon hammer), galvanic skin response.

· Evoked potentials:

o Somatosensory Evoked Potentials (SEP).

o Visual Evoked Potentials (VEP) – with optional photic stimulator.

o Auditory Evoked Potentials (AEP) – with optional ear phones.

o Vestibular Evoked Myogenic Potentials (VEMP) – with optional ear phones.

2 Channels optimized to perform quickly Motor and Sensory Conduction Tests, Needle EMG

97% of all EMG tests are done with the use of one channel.  Channel 1 is set by default to connect electrodes for motor conduction measurement, and Channel 2 is used to plug in electrodes to measure sensory conduction.

Such channel separation speeds up performing the exams.  As soon as the motor conduction velocity is measured, the user can run sensory conduction velocity test, and program will start the response acquisition using the Second Channel.

Two recording channels

While most of EMG tests are administered in a single channel, two channels significantly improve workflow and speed up assessments:  The two recording channels are optimized to record motor and sensory nerve conduction velocity (CV) and needle EMG tests simultaneously. 

By default, the first channel is intended to plug in the electrodes for M-wave testing, while the second one is designated for electrodes used for sensory nerve conduction velocity during NCS. 

This channel configuration allows considerable saving of examination time.  Upon motor CV-test completion, run a sensory CV test, and the software will run automatically the second test using Channel 2.

Two software-switchable outputs for electrical stimulator electrodes

Two pairs of stimulating electrodes can be placed on the veterinary patient, and either of them can be used for stimulation – switched from software.

Thus, there is no need to physically re-connect the electrodes.

Dedicated keyboard

Neuro-MEP-Micro-V features a designed keyboard that gives an easy access to all main functions – adjusting stimulus, starting stimulation, add data to analysis, etc. – without changing the hand position.  All required controls are always at your fingertips.

The built-in miniature graphic monitor allows controlling stimulation parameters, as well as checking electrode placement quality during the test.

Speed and ease of use:  All-in-one stimulators, acquisition channels, controls, display

Thanks to a built-in keyboard, EMG studies are simple and fast.  On average, an experienced specialist performs standard EMG study 1.5 times faster with such keyboard compared with a standard computer keyboard and mouse.

The color display shows stimulation parameters and electrode placement quality. With Neuro-MEP-Micro this data is always at hand.

High acquisition quality:  Sampling rate – up to 100 kHz

High sampling rate and analog-to-digital conversion (ADC) capacity allow obtaining recorded traces of exceptional quality under any circumstances:

· Perform acquisition without special grounding, when computer is powered from a common three-wire outlet.

· Obtain sensory responses even after the first stimulus (without averaging).

Neuro-MEP-Micro-V signal-acquisition channels are optimized to record needle EMG, with immunity to noise considerably increased.  It makes needle-EMG study faster and improves the quality of needle-EMG acquisition.

Electrical stimulator with ultra-fast switching between two outputs

Two outputs of the electrical stimulator are software-controlled.  They allow placing two stimulating electrodes on a veterinary patient or research veterinary patient and activate them from software.  Thus, during the exam, there is no need to physically switch the electrodes.

To attach the stimulating electrode, either touch-proof or DIN connector can be used.

Operation in unshielded environments

Neuro-MEP-Micro-V is highly efficient – clinically and economically.  It can be used in any unshielded environment and does not require additional expenses for the specialist’s workplace.  This provides comfort both for a specialist and veterinary patient and improves exam performance.

Advanced analysis tools

The software provides the clinician or researcher with the necessary tools to analyze recorded responses.

Intelligent software with veterinary-specific algorithm

The supplied software features a veterinary-specific algorithm.  It ensures EMG recording, calculation of all major parameters, analysis, and report generation.  

Exceptionally high-quality low-noise physiological preamplifiers, combined with high-efficiency wide-dynamic-range analog-to-digital conversion, digital filtering, and digital signal-processing algorithms, were specifically designed for Neuro-MEP-Micro-V based on extensive research and development.  They ensure excellent noise suppression, clear signal recording, and reliable, reproducible calculation of recorded parameters.

This allows not only better diagnostics, but also reliable monitoring for any changes in follow-up assessments over prolonged periods of time.

Intra-operative monitoring

Designed to work in the electro-magnetically harsh OR environment, Neuro-MEP-Micro-V can be used as a reliable intra-operative monitor during surgery and post-operative recovery.

Reports

Reports – with recorded traces, numeric data, and comments – are generated on-screen, can be saved, printed out, and shared.

Database and data export

Measurement data and interpretation, as well as exam reports, are saved in a well-organized software database.  The data and reports can be printed out either at the time of the assessment, or at a later time, and shared with a referring doctor or researcher.

Recorded parameters can be exported to Excel spreadsheets and other statistical software for further data

analysis making it an ideal tool for research projects.

Portability

The device is pocket-sized, and can be placed in a Carrying Case – along with a notebook computer – and can be powered from the computer.  Hence, it can be used both in the clinic and on a visit.

This means that long-term monitoring system is always at hand no matter where you perform surgery:  at your clinic or at another location.

Software compatibility

Neurosoft Software enables highly efficient operation – saving both capital and operating costs – through a number of compatibility features:

Multiple Neurosoft Software:  Neurosoft Software for various Neurosoft instruments can be installed on the same computer – with no conflict between them.  Moreover, all software can share a single database – for greater convenience and work-flow efficiency.

Multiple computers:  Although only one computer can be used for diagnostic test data recording, each Neurosoft Software License allows using software on an unlimited number of computers.  Thus, the data can be recorded on one computer, and then, the data can be shared, analyzed, reviewed on other computers – with no additional Software Licenses.

Other applications:  Neurosoft Software can operate on a computer with Microsoft Office applications – Word, Excel, Outlook, PowerPoint, Access, Project, as well as Adobe and accounting software.  This is particularly efficient in smaller clinics.

Internet:  Computers with Neurosoft Software installed can be connected to the Internet.  In an unlikely and rare event that a Microsoft Operating System update affects a Neurosoft software component, it can be restored by Neurosoft software re-installation, with no loss of data. 

Information system integration

Most clinics, networks and research institutions are equipped with information systems to store and process their data.  HL7 (Health Level 7) is the most commonly used interface engine for exchange, integration, sharing and retrieval of electronic data.

HL7-compatibility allows integrating Neuro-IOM-16-V into the information system of a veterinary clinic, clinical network, or research institution.
