Abstract:
Objective To explore the clinical effect of transcranial direct current stimulation(tDCS)treatment strategy based on bi-modal balance model on upper limb dysfunction after ischemic stroke.Methods From October,2023 to December,2024,60 patients with ischemic stroke in General Hospital of Ningxia Medi-cal University were randomly divided into control group(n=30)and experimental group(n=30).Both groups received basic rehabilitation,the control group received tDCS based on the theory of interhemispheric competi-tion model,and the experimental group received tDCS based on the theory of bimodal equilibrium model,for four weeks.Before and after intervention,the effect of both groups was evaluated using Fugl-Meyer Assessment-Upper Extremities(FMA-UE),modified Ashworth Scale(MAS),Action Research Arm Test(ARAT)and modi-fied Barthel Index(MBI).Neurophysiological parameters such as cortical latency(CL)and central motor conduc-tion time(CMCT)were detected and correlated analysis was performed.Results Two cases in the control group and one in the experimental group dropped down.After intervention,the scores of FMA-UE,ARAT and MBI increased in both groups(|t|>13.748,P<0.001),and the above scores were higher in the experimental group than in the control group(|t|>2.321,P<0.05);the MAS grade of the elbow flexor muscle group improved in the experimental group(|Z|=2.095,P<0.05).The CL and CMCT in both groups de-creased(|t|>2.752,P<0.001),and they were better in the experimental group than in the control group(|t|>2.082,P<0.05).There was a correlation between FMA-UE and CMCT(r=-0.433,P<0.05).Conclusion tDCS based on bimodal balance model can improve upper limb dysfunction more effectively in patients with ischemic stroke.
