Objective: To study an anti resistance active exercise training method which is consistent with the principle of "transcendental goal power" to promote the plasticity change of central nervous system (CNS) in order to recover the motor function after CNS injury, observe its clinical effect and explore its mechanism. 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 Chi-Open Access https://doi.org/10.4236/jbise.2019.1212042 515 J. Biomedical Science and Engineering nese Medicine Daoyin feedback rehabilitation technique is an effective method to improve elbow joint function of hemiplegia patients with cerebral infarction.
To investigate the relationship between muscle strength and sEMG of biceps brachii during elbow flexion by measuring the maximum muscle strength and sEMG value of normal children and adults, and to analyze their sources, so as to lay a theoretical foundation for the method of motor program reconstruction to restore the function after brain injury, 30 healthy children aged 9 -10 years and 30 adults aged 20 -30 years were randomly selected. 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.
