NeuroTrac® MyoPlus 4 Pro

New and Improved touch-screen with full colour display. The new user friendly interface makes it a self-explanatory unit with the interactive learning on the go, including electrode placement, running EMG graph, EMG biofeedback Games and templates as well as many other helpful tools.

Pre-set programmes for Incontinence treatment, Sports and muscular development, neuromuscular Rehabilitation.
Designed for Physiotherapist in mind to be used as a portable tool. Suitable as a personal trainer for in-clinic or home use (under guidance).
2 channel EMG (Biofeedback) combined with 4 channel NMES (stimulation).
2 channel ETS (EMG triggered stimulation) with stimulation on 4 channels.
Simple single-phase or multiphase operation: multiphase allows EMG/ETS/STIM to be combined in one programme.
Multilingual LCD screen and voice prompts for Biofeedback.
Manual and Automatic threshold control.
EMG Biofeedback between stimulation (muscle activity and tiredness indication when using muscle stimulation).
Stand alone device or used in conjunction with established multilingual software.
Up to 10 metres of wireless connection for NeuroTrac Software.
For home users: Produces and prints (with the optional PC Software) the comprehensive patient progress reports on a day to day basis providing average readings (2 channels) on work/rest, peak, onset and muscle release times, work and rest deviations and the average mA current.
Used as a learning tool for both patient and clinician with emphasis on improving treatment techniques in the use of EMG and Neuromuscular stimulation.

Dual channel EMG

EMG Range: 0.2 to 2000 μV RMS (continuous)
Sensitivity: 0.1 μV RMS
3 Accuracy: 4% of ìV reading +/-0.3 μV at 200 Hz
4 Selectable Bandpass filter – 3db Bandwidth,
Wide: 18 Hz +/- 4 Hz to 370 Hz +/- 10% – Reading below 235 microvolts 10 Hz +/-3 Hz to 370 Hz +/- 10% – Reading above 235 microvolts
Narrow: 100 Hz +/- 5% to 370 Hz +/- 10% 1.5 Notch filter: 50 Hz (Canada 60Hz) – 33 dbs (0.1% accuracy)
Common Mode Rejection Ratio: 130 dbs Minimum @ 50 Hz
Work / Rest periods: 2-99 seconds
Number of Trials: 1-99

STIM (Neuromuscular Stimulation)

4 channel Stimulator
Amplitude: 0-90 mA into 500 Ohm load – actual mA will tend to be less than indicated due to electrode impedance: at 1000 Ohms load (Electrodes in poor condition) the maximum will be limited to 75 mA, at 1500 Ohms load the maximum will be limited to 50 mA.
Type: Constant current, maximum output voltage 70 Volts +5 / -10 Volts
Waveform: Symmetrical, rectangular, bi-phasic with net zero DC current
Pulse width selection: 50-450 μS (2% accuracy)
Pulse rate selection: 2-100 Hz (2% accuracy)
Work / Rest periods: 2-99 seconds
Time 1 – 99 minutes
Ramp up time: 0.1 – 9.9 seconds
Preset and user programmable treatment Programs
Automatic output shut off with detection of open electrode above 0.5 mA
Battery: 4 x AA. Low battery indication at 5.4 volts +/- 0.2 volts, automatic shut off when voltage drops below the low indication. Replace the batteries immediately! The device goes off automatically when not in use (energy saving): for example when in settings and no key pressed over 1 minute, when in stimulation mode (home screen) and all channels are 0mA.
Expected average battery set life [of standard 800 mAh, alkaline]:
MyoPlus2: 12-16 hours in STIM, 25 hours in EMG mode.
b. MyoPlus4: 8-16 hours in STIM, 25 hours in EMG mode.
