The Study Of Using The Low-Frequency Electrical Stimulation Of Flexors And Extensors Alternating Method In The Rebuilding Of Shoulder And Elbow Functions After Stroke

Purposes: Evaluate the motor function of the stoke patients'shoulder and elbow, objectively; and then study the effects of the flexor-extensor alternative electronic stimulation in rebuilding the upper limbs motor function of the injured side.Methods:First, choose forty cerebral infarction and cerebral hemorrhage patients, divided them into two groups, randomly; and collect the surface electromyogram signal of patients'when they try to do the movement of shoulder flexion, shoulder extension, shoulder abduction, and elbow extension. Pick up the eigenvalue of the integrated EMG(IEMG), the median frequency( MF) and the root mean square value(RMS) from different aspects(such as time domain and frequency domain), and then evaluate the function of the injured upper limb.Second, divide patients into two groups randomly, using the flexor-extensor alternative electronic stimulation; give the common rehabilitation to the control group, and give the extra upper limp flexor-extensor alternation on the common rehabilitation to the treatment group. Similarly, collect the signal of the surface electromyography (sECG), then identify the therapeutic effectiveness according to IEMG, MF, RMS, Fugl-Meyer, Barthel ADL.Results:Firstly, the IEMG, the RMS and the MF of the agonistic muscle, congenerous muscles, and the antagonistic muscle of stork patients'injured sides--when they try to do the movement of shoulder flexion, shoulder extension, shoulder abduction, and elbow extension---are all lower than those of the uninjured sides, especially in the agonistic muscle- which has the highest decrease rate(P
