Study of central and peripheral motor conduction in adults and children
Alternating magnetic field generated by the stimulator easily passes through clothes, skin, scalp, bones and meninges. Reaching the conductive tissues of central and peripheral nervous systems, this field creates alternating electric field which in its turn induces electric current that can activate the neurons as during electrical stimulation. However, if compared to electrical stimulation magnetic stimulation does not cause painful sensations that usually occur due to activation of skin receptors under the electrode and does not require additional preparation time. All this allows performing a wide range of diagnostic tests.
During the study, the recording electrodes are placed on the peripheral muscle and connected to the EMG system. They help obtain the response to the stimulation of the motor cortex representing the respective muscle. Studying the obtained waveform, amplitude and latency allows estimating the state of the motor pathway starting from the cortex.
Diagnostics of neurological disorders
The system allows for quick and painless study of central and peripheral motor pathways, examination of the cranial nerves which is important for early diagnostics, assessment, prognosis and monitoring of various neurological disorders including multiple sclerosis, amyotrophic lateral sclerosis, movement disorders, motor neurone disease, and spinal cord injuries. Besides, the paired pulse stimulation configuration allows assessing the functional state of neurotransmitter mechanisms of the central nervous system (CNS), for example pre/post-synaptic GABAA and GABAB receptors.
Perfect match: powerful monophasic magnetic stimulator and latest-generation EMG system for high-quality recording
Neuro-MS capacity ensures obtaining the reproducible response from both upper and lower limb muscles even in patients with high motor threshold. The paired pulse stimulation configuration allows generating the power pulse that facilitates diagnostics in patients with various CNS diseases owing to the increased pulse duration and intensity.
Digital EMG systems of Neurosoft assure perfect synchronization with the magnetic stimulators. High sampling rate and ADC resolution guarantee ultimate quality of the recorded signal. Sophisticated software offers pre-defined protocols with automatic report generation that help perform an examination quickly and save precious time.
The stimulation can be controlled by the magnetic stimulator, software or even coil. We have carefully thought out every detail so that using our devices was just a pleasure.
Single and paired-pulse stimulation
Single pulse stimulation
The recording electrodes placed on the peripheral muscle are connected to the EMG system. Then the muscle representation in the motor cortex is stimulated and motor evoked potential (MEP) is recorded. The study of the obtained waveform, its amplitude and latency allows estimating the state of the motor pathway starting from the cortex.
Our Neuro-MS magnetic stimulator together with EMG system is a smart solution intended to solve your diagnostic tasks faster and easier! The Neuro-MEP.NET software has implemented standard protocol templates to assess the short-interval intra-cortical inhibition (SICI) and facilitation (SICF). There’s no need to remember the steps, just run the test and the software automatically performs all necessary steps and shows you results as tables and graphs.
The support of HL7 standard allows integrating all diagnostic Neurosoft systems into the information system of a healthcare facility.
