ABSTRACT
Objective:To observe the effects of functional electrical stimulation (FES) controlled by brain-computer interface on upper limb motor dysfunction in stroke patients. Methods:From July, 2019 to November, 2020, 34 stroke patients hospitalized in neurological rehabilitation department were randomly divided into control group (n = 17) and experimental group (n = 17). They were treated with simple FES and FES controlled by brain-computer interface, respectively. The reaction time, joint position error of elbow joint, the scores of Fugl-Meyer Assessment-Upper Extremity (FMA-UE), modified Barthel Index (MBI) and event-related desynchronization (ERD) powers of affected upper limb were evaluated before and after intervention. Results:After intervention, the reaction time, joint position error of the elbow joint, the scores of FMA, MBI and ERD power of the affected elbow joint improved in both groups (F > 10.825, |Z| > 3.624, P < 0.05), and they were better in the experimental group than in the control group (F > 5.853, |Z| > 3.201, P < 0.05). Conclusion:FES controlled by brain-computer interface is positive on the rehabilitation of stroke patients with upper limb dysfunction.
