Abstract：Objective To explore the effect of electromyographic perception-assisted robotic training combined with paired associa-tion stimulation on upper limb function in hemiplegic patients after stroke.
Methods From December,2023 to December,2024,120 hemiplegic patients after stroke in Nanjing Pukou People's Hos-pital(Liangjiang Hospital,Southeast University)were randomly assigned to control group(n=60)and experi-mental group(n=60)using random envelope method.Both groups received medication and routine rehabilita-tion training,the control group received traditional muscle strength training combined with paired associative stimulation,and the experimental group received electromyographic perception robot-assisted training combined with paired association stimulation.Fugl-Meyer Assessment-Upper Extremities(FMA-UE),modified Barthel In-dex(MBI),and modified Ashworth Scale(MAS)were conducted before and four weeks after treatment.The sur-face electromyography(sEMG)was used to detect the root mean square(RMS)and integrated electromyography(iEMG)of the biceps and triceps brachii,and to calculate the corresponding co-activation ratio(CR).
Results Nine cases in the control group and four cases in the experimental group dropped down.After treatment,RMS of triceps,CR of flexion elbow,the scores of FMA-UE and MBI increased in both groups(|t|>2.219,P<0.001),and were better in the experimental group than in the control group(|t|>2.084,P<0.05);the biceps RMS and CR of elbow extension significantly increased in experimental group(|t|>3.863,P<0.001),and were better in the experimental group than in the control group(|t|>2.498,P<0.05).The MAS score of biceps improved in experi-mental group after treatment(Z=-4.097,P<0.001),and was better in the experimental group than in the con-trol group(Z=-3.459,P<0.01).
Conclusion Electromyographic perception robot-assisted training combined with paired association stimulation can im-prove the upper limb motor function and the ability of daily living in hemiplegic patients after stroke.
