Soterix Medical MEGA-EMG

The Soterix Medical MEGA-EMG provides an all-in-one digital system

MEGA-EMG

With options for up to 4 or 8 acquisition channels, built-in stimulators, and unique, easy-to-use software, MEGA-EMG can be used to perform almost all known electromyography (EMG), evoked potential (EP), and nerve conduction studies (NCS), including:

  • NCS Motor and sensory conduction velocity, F-wave, H-reflex, motor and sensory inching, motor and sensory conduction collision
  • EMG Spontaneous activity, interference curve, motor unit potentials (MUP), macro EMG
  • MOTOR UNIT NUMBER ESTIMATION (MUNE)
  • NEUROMUSCULAR JUNCTION
  • ADDITIONAL EMG TESTS Blink reflex, sacral reflex, bulbocavernosus reflex, Т-reflex*, galvanic skin response, long loop (transcortical) reflexes
  • SOMATOSENSORY EVOKED POTENTIALS (SEP)
  • VISUAL EVOKED POTENTIALS (VEP)
  • AUDITORY EVOKED POTENTIALS (AEP)
  • VESTIBULAR EVOKED MYOGENIC POTENTIALS (VEMP)
  • COGNITIVE EVOKED POTENTIALS (P300, MMN, CNV, MRCP, P50)
  • TRANSCRANIAL MAGNETIC STIMULATION (TMS)**
  • ELECTRORETINOGRAPHY (ERG)***
  • HEART RATE VARIABILITY (HRV)***
  • INTRAOPERATIVE NEUROPHYSIOLOGICAL MONITORING (IONM)

Modular Architecture

Optional Stimulators

Stimulators

The delivery set of MEGA-EMG systems includes the amplifier unit with the option to add an electrical stimulator-control unit, and an auditory-visual stimulator unit to control an auditory stimulator, a pattern stimulator, and a visual stimulator (LED goggles).

Features:

  • Available in 4 or 8 channel configurations optimized to quickly perform motor and sensory conduction tests.
  • High acquisition quality: A sampling frequency of up to 160 kHz allows recording of high quality traces other devices are unable to detect.
  • Low noise, quick artifact rejection and perfect interference immunity.
  • Modular Architecture: Select a configuration of available amplifiers and stimulators flexible enough to meet any clinical demands.
  • All electronic units connect to a computer via USB interface, allowing for connection of up to 10 units.
  • Portable and ergonomic design: a dedicated keyboard and footswitch greatly simplifies the process of EMG study.
  • Includes state of the art, easy to use software, Neuro-MEP.NET.

State-of-the art software (NEURO-MEP.NET)

State-of-the art software (NEURO-MEP.NET)

Software include:

  • Dozens of default templates to study motor and sensory conduction in most nerves accessible for stimulation
  • A help window that displays correct placement of recording, ground and stimulating electrodes
  • Acquisition and analysis of spontaneous EMG activity, interference pattern, and MUP in one window
  • A breakthrough algorithm for automatic jitter detection
  • Ability to perform motor and sensory conduction collision tests using two electrical stimulation channels
  • Automatic detection of the main components of evoked potentials during acquisition of SEPs from different sites
  • Report generation upon study completion that include patient's data, tables, graphs and native traces obtained during the tests and can be edited easily and customized according to individual demands
