Athletic injury are caused by the trauma encountered during exercise,which can lead to different degrees of pain,mobility impairment,and even disability in severe cases.Currently,the traditional rehabilitation methods have limited efficacy and personalized treatment is insufficient.Brain-computer interface(BCI)technology provides a novel solution for the rehabilitation of patients with athletic injuries by establishing a direct communication and control channel between the brain and external device.BCI technology has unique advantages in motor function reconstruction,sensory loss improvement,and neuropathic pain regulation through motor intention decoding,neurofeedback,and artificial sensory feedback.BCI system involves three key aspects:brain signal acquisition,analysis and processing,and external device control and the integration of artificial intelligence(AI)provides new insights for signal analysis and processing in it.To further promote the development of new rehabilitation techniques,reduce treatment costs,and promote the overall rehabilitation of patients,the authors elaborated on the characteristics of BCI technology,existing problems in motor rehabilitation,and applications of BCI in athletic injury rehabilitation so as to provide reference and inspiration for researchers in related fields,accelerate innovation,breakthrough,transformation and application of BCI technology,and benefit more patients with athletic injuries.
