The field of rehabilitation healthcare is facing both opportunities and challenges due to issues such as the increase in the number of patients with chronic diseases and the ageing of the population. With the increasing demand for rehabilitation healthcare, these issues are gradually gaining attention. Brain computer interface (BCI), as a brand new diagnostic and therapeutic means, cross-fertilises multiple disciplines, while hybrid brain-computer interface (HBCI) technology is a research hotspot in recent years, which breaks through the limitations of the unimodal BCI technology by combining the two paradigms, and brings a new hope to patients with stroke and other diseases. This paper first analyses the current situation of the rehabilitation medical field and discusses the importance of receiving rehabilitation medical treatment for patients with chronic diseases and other diseases. Subsequently, it introduces the development history of brain-computer interface technology, analyses its research status, and explains its technical principles. Then, the application of hybrid brain-computer interface technology is analysed from three types of diseases, namely, limb movement disorders, chronic consciousness disorders, and mental illnesses. Finally, the current problems of hybrid brain-computer interface technology are discussed, and the prospect of the application of hybrid brain-computer interface technology in the field of rehabilitation medicine is outlooked.
