Evaluation Based On Low-Frequency Impulse Electrotherapy For Reconstruct Of Upper-Limb's Function

Objectives1.With the application of surface EMG to evaluate upper-limbs' movement function after stroke objectively.2.To observe the influence of low-frequency impulse electrotherapy Rx in upper-limbs' function after stroke.3.To analyse the difference which various low-frequency electrical stimulating factors influence curative effect in order to optimize low-frequency impulse electrotherapy Rx.Methods40 patients suffered from cerebral hemorrhage or cerebral infarct which according with standard were gathered the sEMG of initiative muscles and cooperative muscles in the movement of upper 1imbs' shoulder,elbow,wrist. The eigenvalues of sEMG such as MAX,IEMG were extracted to evaluate upper limbs' movement function.Patients were divided into 2 groups by random.Control group was accepted standard rehabilitation treatment.And electrical stimulating group was accepted standard rehabilitation treatment plus electrical stimulating.Electrical stimulating group was divided into 4 groups by random arranged by Orthogonal test through combination scheme arranged in groups by three factors and two levels.And patients were accepted low-frequency impulse electrotherapy.Each group was assessed with Fugel-Meyer Functional evaluation scale,CSS scale,Barthel ADL scale respectively before and after treatment.Results1,Comparing with MAX,IEMG of initiative muscles and cooperative muscles of healthy side and trouble side in stroke patients' upper limb,there were significant differences between them(P＜0.05)2,Before and after the treatment of low-frequency impulse electrotherapy,the eigenvalue of sEMG such as MAX,IEMG of upper limbs had the significant differences between them.(P＜0.05)3,The adoption of intermittent wave,impulse frequency of 50Hz,electrodes placed movement point to improve upper limbs' movement function can significantly boost MAX,IEMG,Fugl-Meyer movement function mark and Barthel ADL of upper limbs.Curative effect influenced by each factor from greatness to lightness was:impulse wave＞impulse frequency＞electrodes placed site.Conclusions1,There were difference between healthy side and trouble side in stroke patients.Different muscles had various sEMG in different movements. Compared with Fugl-Meyer movement function scale,CSS scale,Barthel ADL scale,sEMG can evaluate limbs' function more accurately and objectively after stroke.2,Low-frequency impulse eleetrotherapy had positive curative effect on the reconstruction of limbs' function after stroke.It can improve the eigenvalues of sEMG,such as MAX,IEMG;improve Fugl-Meyer movement function and Barthel ADL of upper-limb.3,Different factors had the different curative effects on the treatment of low-frequency impulse electrotherapy with the movement function of limbs after stroke.The optimal project was intermittent wave,50Hz,movement point in low-frequency impulse electrotherapy.
