Study of central and peripheral motor pathways
The magnetic field generated by Neuro-MS/D magnetic stimulator can easily penetrate through clothes, skin and bones. When pulsed magnetic field reaches the nerve structures, it induces electrical current and can excite nerve structures. If EMG is recorded at this moment, motor evoked potential (MEP) can be recorded.
Using this approach cerebral, spinal and peripheral nerve pathways can be studied. Such tests are especially important for studying patients with demyelinating diseases of nervous system, in particular, multiple sclerosis, tumorous and vascular lesions.
The magnetic stimulator can operate with EMG recorders of many manufacturers (through TTL/CMOS trig-in/out sockets). However, the maximum diagnostic capabilities can be achieved, if the device is used together with Neurosoft digital neurophysiological systems.
Neuro-MEP.NET software supplied with Neurosoft neurophysiological systems, for example, Skybox, ensures pre-defined templates for wide range of TMS tests:
- Motor evoked potentials (MEP)
- Central motor conduction time (CMCT)
- Silent period (SP)
- Interhemispheric inhibition (IHI or ipsilateral SP)
- Triple stimulation test (TST)
- Low- and high-frequency rTMS
- Stimulation of phrenic nerve for study of diaphragm response
Thus, we encourage you to consider purchasing our Neuro-MS/D together with our EMG system.
7 coils at your choice
In diagnostic configuration 7 different coils can be delivered including ring coils, figure-of-eight coils, angulated figure-of-eight coils and placebo coils. All coils are equipped with “Pulse” button and “Ready” indicator. A waveform of magnetic field, its penetration depth, stimulus number till overheating, maximal intensity of magnetic induction depend on a type of coil. For example, the maximum induction area of the ring coils is at the inner edge, and the maximum induction area of the figure-of-eight coil is in the center. A suitable battery of coils meets all diagnostic needs: focal stimulation, stimulation of large areas, stimulation of deep and superficial structures.
Peak magnetic field — up to 4 T
The peak magnetic field of Neuro-MS/D reaches 4 T, one of the highest values in the industry. Such intensity helps to get reliable motor response even in the most complicated cases.
Delayed charging mode
While working together with digital EMG system a delay for the capacitor charge is set in the single pulse mode to avoid noise impact from the power supply unit during the acquisition. The range of the delay is 0–9.9 seconds.
Connection to computer via USB port
Neuro-MS/D can be used together with neurophysiological systems made by Neurosoft. Just connect the magnetic stimulator to the computer with installed EMG or EEG software via USB port. Neurosoft is the only company in the industry which produces both professional EMG/NCS and TMS machines. It means that integration between TMS and EMG can be done at very deep level. EMG software can completely control all parameters of magnetic stimulator.
