According to different TMS stimulation pulses, TMS can be divided into three stimulation modes: single pulse TMS (sTMS), double pulse TMS (pTMS) and repetitive TMS(rTMS). STMS is controlled by manual non-rhythmic pulse output, and can also stimulate multiple stimuli, but the stimulation interval is long (such as 10 second), which is mostly used for routine electrophysiological examination. PTMS is often used to study the facilitation and inhibition of nerves. The method is to continuously give two kinds of stimuli with different intensities at a short interval at the same stimulation site, or to apply two kinds of stimulators (also called dual-coil TMS, dTMS) at two different sites. RTMS can be divided into high frequency and low frequency, so it is necessary for equipment to give slow-paced low frequency or fast-paced high frequency rTMS at the same stimulation site. RTMS with different stimulation parameters (mode, frequency, intensity, interval, duration, stimulation location, stimulation direction, etc.). ) have different neurophysiological effects. Low-frequency stimulation mode causes cortical inhibition, while high-frequency stimulation mode causes excitement. Clinically, the purpose of diagnosis and treatment is mainly achieved by capturing and utilizing this biological effect.
At present, transcranial magnetic stimulation technology has been widely used, and the domestic transcranial magnetic stimulation technology has reached the world advanced level, especially the appearance of "inert liquid cooling system", which is a new milestone of transcranial magnetic stimulation technology, making this technology really work continuously for a long time and making it widely used in clinic. The treatment of depression has passed the FDA certification in the United States.
