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.
