ABSTRACT=<sec id="sec1"><title>Background</title><p>The characteristics of disorders of consciousness (DOC) are changes in arousal and/or awareness caused by severe brain injuries. To date, the management of DOC patients remains a complex and challenging task, and neuromodulation techniques offer a promising solution. However, a bibliometric analysis focusing on neuromodulation techniques in DOC is currently absent. The aim of this study is to provide a bibliometric visualization analysis to investigate the research hotspots and frontiers in the field of neuromodulation techniques in DOC from 2012 to 2022.</p></sec><sec id="sec2"><title>Methods</title><p>The publications were collected and retrieved from the Web of Science (WoS) from 2012 to 2022. CiteSpace and Microsoft Excel were utilized perform the first global bibliographic analysis of the literature related to neuromodulation techniques for DOC.</p></sec><sec id="sec3"><title>Results</title><p>The analysis included a total of 338 publications. From 2012 to 2022, a consistent yet irregular increase in the number of articles published on neuromodulation techniques in DOC was observed. Frontiers in Neurology published the highest number of papers (<italic>n</italic> = 16). Neurosciences represented the main research hotspot category (<italic>n</italic> = 170). The most prolific country, institution, and author were the USA (<italic>n</italic> = 105), the University of Liege (<italic>n</italic> = 41), and Laureys Steven (<italic>n</italic> = 38), respectively. An analysis of keywords revealed that UWS/VS, MCS, and TMS constituted the primary research trends and focal points within this domain.</p></sec><sec id="sec4"><title>Conclusion</title><p>This bibliometric study sheds light on the current progress and emerging trends of neuromodulation techniques in DOC from 2012 to 2022. The focal topics in this domain encompass the precise diagnosis of consciousness levels in patients suffering from DOC and the pursuit of efficacious neuromodulation-based evaluation and treatment protocols for such patients.</p></sec>
