Abstract:

Objective To investigate the effects of visual motion-induced brain-computer interface (BCI) technology on upper limb motor function and cognitive function of patients with stroke.
Methods From July, 2021 to March, 2022, 50 stroke patients with upper limb hand dysfunction in Shaanxi Provincial Rehabilitation Hospital were randomly divided into control group (n = 25) and experimental group (n = 25). Both groups received conventional rehabilitation therapy, in addition, the control group received passive rehabilitation training, and the experimental group received visual motion-induced BCI rehabilitation training, for two weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and Montreal Cognitive Assessment (MoCA) before and after treatment. Brain participation was evaluated during the whole training process of the experimental group.
Results Before treatment, there was no difference in the scores of FMA-UE, MBI and MoCA between two groups (P > 0.05). Two weeks after treatment, the scores of FMA-UE, MBI and MoCA improved in both groups (t > 2.481, P < 0.001), and were better in the exprimental group than in the control group (t > 2.453, P < 0.05); the mean brain participation of the experimental group increased 21% after treatment.
Conclusion Visual motion-induced BCI rehabilitation training could promote the recovery of motor function of upper limb, and cognitive function of patients with stroke.
