Abstract:
Objective:To investigate the effect of separation exercise training of upper limb robot in improving upper limb motor function of stroke patients,and to explore the underlying mechanism by transcranial magnetic stimu-lation motor-evoked potential(MEP)evoked potentials. Method:Stroke patients were randomly divided into the experimental group(n=21)and the control group(n=23).The experimental group was trained with a fixed trajectories(the separation movement of elbow flexion-extension and shoulder adduction-abduction),while the control group underwent upper limb robot training with random movement trajectories(a compound action that can reach for objects).Both groups received robot train-ing once a day,20min/time,5 times/week for 3 weeks.The Fugl-Meyer assessment of upper extremity(FMA-UE)and modified Barthel index(modified Barthel index,MBI)were used to evaluate motor function.The la-tency period and central motor conduction time(CMCT)of MEP were detected before and after treatment. Result:After 3 weeks of treatment,the FMA-UE,MBI and MEP were improved compared with before treat-ment in the experimental group(P＜0.05),There was no significant difference between the FMA-UE,MBI and MEP of the control group and that before treatment(P＞0.05);There were no significant differences in in FMA-UE,MBI and MEP between-group comparisons after 3 weeks of treatment. Conclusion:The separation exercise training of the upper limb robot can improve the upper limb motor func-tion and enhance daily living activities in stroke patients,which may be related to enhanced remodeling of brain function in stroke patients.
