Neuro-MEP-Micro General Properties

·                   Surface EMG (spontaneous activity, interference curve)

·                   Stimulation EMG (M-wave, sensory action potential, F-wave, H-reflex (also including paired stimulation), T-reflex*, blink reflex, magnetic stimulation**)

·                   Rhythmical Stimulation (Decrement-test) (impulse series, stimulation by user-defined stimulation algorithm, tetanization)

·                   Needle (Local) EMG (spontaneous activity, interference curve, motor unit potentials)

·                   Somatosensory Evoked Potentials (short- and long-latency SEP)

·                   Transcranial Magnetic Stimulation**

EMG system Neuro-MEP-Micro can be supplemented with the software module and set of stimulators Neuro-EP for short-, middle- and long-latency auditory, somatosensory, visual and cognitive (Р300, MMN, CNV) EP study.
