Knowledge map of transcranial magnetic stimulation for insomnia: a bibliometric and visual analysis

Through scientometric analysis of studies on TMS for insomnia, we visualize the involvement of countries, authors, institutions, cited authors, keywords, and cited references using a knowledge graph. Cluster analysis has revealed the primary research areas in this domain, focusing on the preference for low-frequency TMS in treating insomnia and the superior therapeutic outcomes achieved through stimulating the dorsolateral prefrontal cortex. These discoveries serve as a guide for clinical practitioners in conducting subsequent research endeavors. This is crucial for swiftly and precisely identifying key information in this field.
