| Stroke is an acute neurological deficit caused by vascular reasons, with a high rate of disability and mortality, causing a serious social and economic burden. Early assessment and personalized rehabilitation programs are crucial for the functional recovery of stroke patients. Compared with traditional assessment methods, functional near-infrared spectroscopy (fNIRS) not only has a lower cost and is portable, but also has strong resistance to motion artifacts, and has broad application prospects in the rehabilitation assessment of stroke patients. This article reviews the basic principles of fNIRS and its application progress in the assessment of motor, language, cognitive, mental and swallowing function disorders after stroke. Previous studies have shown that fNIRS can effectively detect changes in brain region activation and functional connectivity, providing important evidence for rehabilitation treatment. However, fNIRS still has some limitations in practical application, such as relatively limited detection depth and susceptibility to external signal interference. Therefore, future research needs to be strengthened in multiple fields, increase sample size, and combine with multimodal technologies to further promote the application of fNIRS in the rehabilitation assessment of stroke. |
