Application Of Brain-computer Interface Technique In Rehabilitation Of Lower Extremity Motor Function In Stroke Patients With Hemiplegia

Objective: To investigate the effect of brain computer interface technology on the motor function of lower limb in stroke patients with hemiplegia.Methods: From January 2016 to January 2017,40 patients with stroke hospitalized in the Department of Rehabilitation Medicine,the second affiliated Hospital of Nanchang University were randomly divided into observation group(n =20)and control group(n = 20),two groups were treated with routine rehabilitation training,The observation group received brain computer interface rehabilitation treatment for 1 hour once daily,5days per week for 4 weeks in addition to conventional treatments.The control group was trained with the same amount of physical feedback of lower limb flexion and extension.The lower limb motor and balance function and ADL were respectively assessed with Fugl-Meyer score(FMA),modified Bathel index score(BI)and Motor Assessment Scale(MAS)before and4 weeks after treatment.Result: After treatment,both groups showed significant improvement in Fugl-Meyer score(FMA),modified Bathel index score(BI)and Motor Assessment Scale(MAS)compared with that before treatment(P<0.05).Based on FMA,BI and MAS statistically significant improvement were observed in the treatment group comparing with the control group(P<0.05).Conclusion: BCI is helpful to the recovery of lower extremity motor function in patients with hemiplegia,and it can improve the activity of daily life.
