NeuroTrac MyoPlus 4 EMG

The Neurotrac Myoplus 4 is a dual channel EMG unit. It is packed full of features to make any rehab easy as possible.

FEATURES

• The Classic Biofeedback / ETS / Stimulation device. A proper tool for training and progress assessment.
• 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 PC 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.

TECHNICAL DATA

EMG

• Dual-channel EMG
• EMG Range: 0.2 to 2000 μV RMS (continuous)
• Sensitivity: 0.1 μV RMS
• Accuracy: 4% of μV reading +/-0.3 μV at 200 Hz
• Selectable Bandpass filter – 3db Bandwidth,
• a. 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
• b. Narrow: 100 Hz +/- 5% to 370 Hz +/- 10%
• 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]:

MyoPlus 4: 8-16 hours in STIM, 25 hours in EMG mode.

Environmental Conditions for use:

+5 to +40 degrees Centigrade. 15-93% Humidity.

Environmental conditions for storage & transport:

-25 to +70 degrees Centigrade. 15-93% Humidity.

Physical Dimensions: Length 150 mm, Width 89 mm, Depth 35 mm

Weight: MyoPlus 4, device: 0.16 Kg (without batteries).
