Effect Of Rehabilitation Robot On Upper Limb Motor Function In Patients With Hemiplegia After Stroke And Mechanism Research

Objective(s):To explore the effect of intelligent upper limb rehabilitation robot on upper limb motor function in patients with hemiplegia after stroke and its treatment mechanism.Methods:Forty patients with hemiplegic upper limb stroke were selected and randomly divided into an experimental group and a control group,with 20 cases in each group.Both groups of patients were given basic drug treatment and conventional rehabilitation therapy.The experimental group was given intelligent upper limb rehabilitation robot training,and the control group was given upper limb electronic biofeedback treatment.Both groups were given Fugl-Meyer upper limb motor function assessment and resting functional magnetic resonance scan before treatment and after 4 weeks of treatment.Results:1.Before treatment,there was no statistically significant difference in the FMA-UE scores(upper limb,wrist,hand and total score)between the experimental group and the control group(P?0.05),which was comparable;after treatment,the FMA-UE scores(upper limb,wrist,hand and total score)of the two groups of patients were improved compared with before treatment(P?0.05).Intelligent upper limb rehabilitation robot training and electronic biofeedback treatment can improve patients'upper limb motor function;The FMA-UE score(upper limb,wrist and total score)improved better than the control group,the difference was statistically significant(P?0.05),and the improvement in the FMA-UE score of hand function in the experimental group was not statistically different from the control group Academic significance(P?0.05).2.The ReHo value of the patients in the experimental group and the control group after treatment was higher than that before the treatment,the difference was statistically significant(P?0.05),intelligent upper limb rehabilitation robot training and electronic biofeedback treatment can promote the activation of neurons in the cerebral cortex of the patient's ROI area;The increase of ReHo in the experimental group after treatment was higher than that in the control group,the difference was statistically significant(P?0.05),the activation intensity of the intelligent upper limb rehabilitation robot training on the brain neurons in the ROI area of the patient was higher than that of electronic biofeedback treatment;the experimental group and there was no statistically significant difference in the fALFF value of the ROI area of the control group after treatment compared with that before the treatment(P?0.05);there was no significant difference in the degree of change of the fALFF value of the ROI area of the experimental group before and after treatment compared with the control group(P?0.05).3.?FMA-UE and ?ReHo were positively correlated before and after treatment in the experimental group and the control group.The greater the improvement in upper limb motor function,the greater the increase in ReHo value in the ROI area;the experimental group ?FMA-UE and ?ReHo were significantly correlated(r=0.522,P=0.003),the control group ?FMA-UE and ?ReHo were moderately correlated(r=0.447,P=0.13),and the activation intensity of intelligent upper limb rehabilitation robot training on ROI neurons was better than electronic biofeedback Treatment;there is no correlation between ?FMA-UE and ?fALFF before and after treatment in experimental group and control group(P>0.05).Conclusions:1.Intelligent upper limb rehabilitation robot training and electronic bio feedback therapy can improve stroke motor function of hemiplegia;compared with electronic biofeedback therapy,intelligent upper limb rehabilitation robot training has obvious advantages in the recovery of patients' shoulder,elbow and wrist functions.Functional recovery has no advantage.2.The treatment mechanism of intelligent upper limb rehabilitation robot training may be related to the increase of the activation intensity of neurons related to the motor cortex.ReHo analysis can be used as a neuroimaging index to predict the motor function of upper limbs in stroke hemiplegia,and has high clinical application value.
