Efficacy of closed-loop-based transcutaneous electrical acupoint stimulation combined with stepped motor imagery training for upper limb and hand function rehabilitation after stroke
Objective To assess the efficacy of transcutaneous electrical acupoint stimulation(TEAS)combined with motor imagery-based training for hand and upper limb motorfunction rehabilitation after stroke.Methods Eighty stroke patients from January 2021 to April 2023 were randomly divided into study group(n=40)and control group(n=40).Both groups received conventional rehabilitation.The study group received additional TEAS combined with stepped motor imagery training,while the control group received TEAS and attention-placebo control intervention for 4 weeks.The hand and upper limb motor functions ofpatients were assessed with the Fugl-Meyer upper limb assessment scale(FMA-UE),wooden box handicap test(BBT),modified Ashworth scale(MAS)and modified Barthel index(MBI)before and after the treatment.The hand mental rotation test was used to evaluate the patient's motor imagery ability before intervention.Results There were 35 and 36 cases in study and control groups who completed the intervention and were included in the final analysis,respectively.After 4 weeks of treatment,the FMA-UE,BBT,and MBI scores in both groups were significantly improved(t>3.545,P<0.001).The total FMA-UE score and proximal and distal subscores in the study group were significantly better than those in the control group(t>2.187,P<0.05).Correlation analysis showed a significant negative correlation(r=-0.676,P<0.001)between the change in the distal subscores of FMA-UE and the pre-treatment reaction time during HMRT in the study group.Conclusion TEAS combined with stepped motor imagery training can effectively improve the upper limb and hand motor function after stroke,and its efficacy is related to the patient's baseline motor imagery ability.
