2-, 4- and 5-channel Neuromyoanalyzer modifications.
Wide range of different
variants of functional
capabilities for a user –
from inexpensive up
to an expert class device;
supplied with flexible
combinability of software-
methodical versions
and hardware
modifications.
Effectively used
in functional diagnostics
cabinets, neurological
departments,
sport medicine
and scientific studies.
Wireless connection of neuromyograph patient's
block to remote controller, pattern stimulator
and footswitch significantly reduces the number
of connecting cables and increases study
comfort both for a doctor and for a patient.
|
| Patient's block |
Amplifiers |
- 2, 4 or 5 galvanic insulated EMG and EP amplifiers
- USB interface for connection to PC
- Wireless interface for footswitch, remote controller and pattern stimulator control

Electrodes
|
- current stimulating with fixed electrode gap (for children and adults) with felt or metal end
- surface deferent with fixed electrode gap
- current fork stimulating (for children and adults)
- ground surface electrode
- needle and cup electrodes
|
Remote Controller (RC)
(Makes carrying out of repeated standard studies much easier without using keyboard and PC mouse) |
|
- Used as traditional neuromyograph keyboard and electrostimulator handle simultaneously
- Managing neuromyograph with the help of RC is equal to managing a mobile phone
- «Fast start» of a new test with the help of RC significantly speeds up the analysis of combined and symmetrical muscles or nerves
- PC buttons and wheel-regulator for each of the test have different meanings and allow performing all the necessary functions

Electromyographic studies
|
MCV |
SCV |
F-wave |
- Stimulus artifact rejection algorithm allows recording responses of short nerves
- Integral diagrams compactly display the main results of tests already carried out
|
|
H-reflex |
Blink reflex
Graphic form of results reflects the damage level. |
- Rhythmic stimulation There is an opportunity to create the stimulation scenario and carry it out in automatic mode or manually.
|
|
Surface EMG-express
Allows studying many muscles under different function tests. |
Needle EMG
Allows simultaneous recording different kind of activity, injection, spontaneous, MUP and interferent. |
- The library of nosological study scenarios allows saving time in type studies.
- Surface multichannel EMG ensures the study of mutual muscle group work, calculating the reciprocal, synergism, adequacy coefficient.

Pattern reversal visual evoked potentials
|
The stimulator consists of LCD-monitor
and wireless pattern-reversal
checkerboard generator (PRCG).
Generator is fixed
to the back side of a monitor
with the help of a standard
VESA-100 fixation.
Owing to wireless control
a monitor with PRGC
can be located at the
necessary cabinet place
over a distance from
the doctor's working place.
PRGC monitor can be used
as second Windows monitor
for comfort location of signal
windows, diagrams, etc.
Main stimulator characteristics
- Pattern presentation: full screen, one of the halfs, one of the quarters, central part;
- Picture type: board, horizontal or vertical stripes;
- Picture quality: 800х600 pix, 16 million colours.

Auditory evoked potentials study
|
Short-latency auditory EP of brainstem |
Middle-latency auditory EP |
Long-latency auditory EP |
|
Specially calibrated stereo headphones are used as phonostimulator.
- Stimulus type: click, burst, tone;
- Stimulus intensity (SPL): 1–110 dB;
- Control: independent, right or left channel;
- Contralateral noise masking.

Study of visual evoked potentials for a light flash
|
Photostimulation is performed with the help of original "goggles" on the basis of impulse LED.
- stimulation intensity 2250±750 kJ/м2
- flash duration: 1,0±0,1 мs
- field of view: not less then 20°
- flash repetition rate: 0,2 - 1,6 Hz
