Methods: The potential of CNS was induced by six-step Daoyin technique of Chinese medicine, and the potential signal was received in real time by bio-electrical signal receiving equipment and displayed in curve form. Combined with the Operant conditioning biofeedback technique, targeted guidance was given to patients to continuously enhance the action muscle signal intensity and weaken the antagonistic muscle signal intensity, so that the motor program was gradually re-established. Sixty-four patients with hemiplegic elbow dysfunction of old cerebral infarction who had been trained but could not be improved further and had a history of more than 1 year were treated for one course, 90 times and 45 minutes each time. Lovett, Elbow Rom, Fugl-Meyer, program signal intensity and proportion were evaluated before and after treatment. The data were analyzed statistically. Before and after treatment, Lovett MMT, ROM of elbow joint, Fugl Meyer, motor program signal intensity and proportion were assessed, and the data were statistically analyzed. Results: After treatment and before treatment, there was a significant difference between the functional evaluation data (P < 0.01). The function of elbow joint was improved;this is the result of reconstructing the motor program on the basis of developing the potential of CNS by means of the “transcendental goal power” mechanism of the method. There was no recurrence after 6 months of follow-up. Conclusion: The Chinese Medicine Daoyin feedback rehabilitation technique is an effective method to improve elbow joint function of hemiplegia patients with cerebral infarction.展开更多

Methods: The air spring with adjustable strength was used to provide the power of resistance active movement, and the neurological training cervical audio-visual synthesis training software was used to automatically guide patients to perform resistance active movement training of the cervical spine. Thirty two patients with cervical spondylosis were enrolled for treatment, and SPSS26 was used to statistically analyze the VAS, Lovett muscle strength, head and neck range of motion and C2-3 vertebral body curvature before and after the treatment. Result: There were significant differences in posterior cervical muscle strength (Lovett), dizziness, shoulder and neck pain (VAS) and C2-3 vertebral curvature before and after training in 32 patients (p˂0.001). Conclusion: The application of neurological training cervical vertebra self rehabilitation training instrument can effectively relieve clinical symptoms, restore head and neck range of motion, improve nape muscle strength, restore the dynamic balance of front and rear cervical muscle strength, and also can correct the abnormal physiological radian of the cervical vertebra.展开更多

The muscle strength and sEMG of biceps brachii during elbow flexion were detected and recorded, and the data were statistically analyzed. The muscle strength of children was significantly lower than that of adults (P < 0.001), and the sEMG value of biceps brachii was significantly lower than that of adults (P < 0.001), but the sEMG value per kilogram force of children was significantly higher than that of adults (P < 0.01). The results show that there was a very significant difference in pull (efficiency) between adults and children when there was no significant difference in SEMG signal intensity. This is because although children’s central nervous system has matured, the muscle tissue has not been well trained, resulting in insufficient muscle strength. The muscle strength of adults is significantly higher than that of children, because they have been exercising for a long time after the development of the central nervous system. It is proved that sEMG signal is not produced by muscle contraction itself, but comes from the motor program signal of central nervous system which drives muscle contraction, and it is produced before muscle contraction.</span> </p>展开更多
