Stimulation electromyography in determining the mechanism of therapeutic action of adaptive feedback for patients with traumatic disease of the spinal cord

The aim of this work was to study the mechanism of the therapeutic action of the adaptive biofeedback method using visual and auditory feedback to repair movement disorder in patients with traumatic disease of the spinal cord in case of complex spine fracture on the basis of data on the changes in electrophysiological properties of muscles and spinal motor neurons involved in the pathological process. Sixty four patients were treated and tested in the first month after injury, 40 of them male and 24 female. The age of the patients ranged from 19 to 40 years, the average age being 28,3 years. All the patients were subjected to a complete orthopedic and traumatological, neurological, laboratory, radiographic and electrocardiographic examination. Electroencephalography was also carried out if required on therapeutic grounds. After adaptive biofeedback an increase in total excitability of the patients’ spinal motor neurons by a factor of 2,2 was noted. The involvement of alpha-BMN increased by a factor of 2,5 and that of alpha TNM increased by a factor of 1.6 approaching the performance of healthy people. The sensitivity of primary muscle endings increased by 64,5%. The degree of attenuation of the re-induced spinal reflex practically did not change.
