Abstract：Objective To explore the effect of transcranial direct current stimulation(tDCS)combined with auricular vagus nerve stimulation(ta-VNS)on lower limb function in patients with cerebral hemorrhage.Methods A total of 40 patients with hemiplegia after cerebral hemorrhage admitted to Guangdong Sanjiu Brain Hospital from December 2022 to December 2023 were randomly sampled and divided into a control group(20 cases)and an observation group(20 cases).Both groups were given conventional rehabilitation treatment.The control group was given tDCS before exercise therapy,and the observation group was given tDCS and ta-VNS before exercise therapy.Before and after 4 weeks of treatment,the three-dimensional gait analysis and evaluation system was used to analyze the temporal and spatial parameters of lower limb gait during walking,including standing phase,swing phase,step length,step speed,step frequency,stride length,and sagittal lower limb joint mobility.Fugl-Meyer assessment for the lower extremity(FMA-LE)was used to analyze the motor function of the lower limbs.The Berg balance scale(BBS)was used to analyze the balance function of patients and compare between groups.Results There was no significant differences in the three-dimensional gait analysis index,FMA-LE and BBS scores between the two groups before treatment(P>0.05).After 4 weeks of treatment,the three-dimensional gait analysis index,FMA-LE and BBS scores of the two groups were improved compared with those before treatment,and the improvement effects of the observation group were better than those of the control group,and the differences were statistically significant(P<0.05).Conclusion tDCS combined with ta-VNS treatment can significantly improve the lower limb motor function of patients with hemiplegia after intracerebral hemorrhage,and improve their balance and walking ability.
