Objective ① through sEMG signal characteristic analysis, objective evaluation of the functional status of stroke patients with upper limb movement; ② observed pulse modulation frequency electrical stimulation stellate ganglia, brachial plexus, Sanyang hand acupoints, shoulder elbow muscle movement points, on brain shoulder and elbow function after stroke upper limb reconstruction studied to optimize treatment. Methods ① Application sEMG acquisition systems, collecting 30 cases of stroke in patients with shoulder and elbow agonist activity Collaboration muscle sEMG signals; ② sEMG eigenvalue extraction, the patient health, ipsilateral shoulder and elbow movement sEMG were compared. ③ According to the principle of the patients were randomly divided into three groups, the application of pulse modulation frequency electrical stimulation stellate ganglia, brachial plexus, Sanyang hand acupoints, shoulder elbow muscle movement points. Treatment 1 times / day, 6 times / week, continuous treatment for two months; ④ before and after treatment were used sEMG and FMA, ADL Barthel index scale evaluation of the clinical efficacy of each group. Results ① in a quiet state, there is no active muscle contraction, the sEMG signal change; ② different post-stroke patients shoulder and elbow movements, active muscles and Collaboration contralateral muscle sEMG eigenvalues ??iEMG, AVE, MAX were compared with ipsilateral highly significant difference P <0.01; ③ deltoid different actions in patients after stroke, sEMG eigenvalues ??iEMG, AVE was significant difference P <0.05, MAX was no significant difference P> 0.05; ④ pulse modulation frequency electric therapy, three groups of patients with stroke shoulder and elbow different actions, sEMG eigenvalues ??iEMG, MAX than before treatment were highly significant difference P <0.01; ⑤ pulse modulation frequency electric therapy, stroke patients among the three groups sEMG evaluation of muscle function reconstruction are not the same, A group of right supraspinatus muscle, pectoralis major functional reconstruction effective than the other two groups, B group right deltoid, triceps, muscle function after elbow reconstruction more effective than the other two groups; ⑥ pulse modulation frequency electric After treatment, the three groups of patients with stroke assessment scale than before treatment were highly significant difference P <0.01; ⑦ pulse modulation frequency electric therapy, patients with stroke scale among the three groups were significantly different evaluation of P <0.05, B group, C group than the A group. Conclusion ① ipsilateral stroke patients with contralateral significant difference sEMG, sEMG can objectively evaluate the sensitivity of muscle function in patients after stroke and active states; ② sEMG and scale evaluation complement to more objectively reflect the status of stroke patients; ③ Pulse modulation frequency electrical stimulation of the stellate ganglion, brachial plexus reconstruction of shoulder function for a significant effect; ④ pulse modulation frequency electrical stimulation stellate ganglia, brachial plexus, Sanyang hand acupoints on the shoulder and elbow function reconstruction better efficacy .
