Repetitive transcranial magnetic stimulation（ rTMS） is a new neural stimulation technique developed based on transcranial magnetic stimulation（ TMS）. It has been performed on the principle of electromagnetic induction. It works by stimulating the cortex non-invasively and changing its excitability for therapeutic purposes. In recent years， rTMS has been widely studied and applied in the treatment of insomnia， and some curative effect has been achieved. This paper reviews the clinical research status of rTMS in the treatment of insomnia， by summarizing the relevant studies at home and abroad.
