Advanced therapeutic configuration of Neuro-MS/D covers all clinical needs of rTMS practitioners. Convenient system on a trolley includes high-frequency and high-intensity stimulator with effective cooling system and convenient flexible arm for coil positioning
The principle of therapeutic magnetic stimulation is based on the following. The magnetic stimulator uses the magnetic pulses of short duration. The emerging high-intensity electromagnetic field easily penetrates through clothes, cranium bones and soft tissues. It impacts on deep nerve centers, peripheral nerves, cerebral and spinal cord, which is inaccessible for other kinds of stimulation.
This stimulation is commonly used to treat depressions (including severe and drug-resistant), tinnitus. Besides, there are positive and encouraging results obtained at rehabilitation of post-stroke patients and other neurological and psychiatric diseases.
It includes main unit with cooling system and cooled coil placed in a flexible arm that ensures fast and easy coil fixation in any position by rotating one screw. All that is mounted on a smooth-running trolley. The computer to control the stimulation can be also included in the delivery set. In this configuration system allows performing long-term sessions of biphasic rTMS with up to 30 Hz frequencies and up to 5 Hz maximum intensity.
Select any Neurosoft EMG recorder from a wide list of neurophysiological systems to record motor evoked potentials (MEPs).
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:
Number of pulses generated during one session – up to 10 000
The cooling unit and cooled coils included in the delivery set of Neuro-MS/D are intended to avoid overheating of coils during the long-term treatment session. The cooling unit itself is a tank with the cooling liquid, the pump running the cooling liquid through the coil and the fridge. The unit allows increasing continuous operation of up to 10 000 pulses without overheating. Practically, it means that stimulator can operate for hours without overheating.
Neuro-MS.NET software to control magnetic stimulator
This delivery set includes a special Neuro-MS.NET software that allows customizing any stimulation protocols. This software keeps patient database, determines motor response threshold and controls the stimulation courses and sessions. You can perform the stimulation according to pre-defined ptorocols and also create your own ones or customize the preset stimulation programs.
Preset protocols are used to treat depression, Parkinson disease, stroke, tinnitus, etc.
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.
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.
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.
Neurostim is intended for transcranial noninvasive stimulation with direct low current.
