The influence of various factors on recovery process of motor control of paretic limbs muscles in patients with pyramidal syndrome

Abstract

In order to study the specific features of central nervous system reaction to restoration of the cranial vault bone defects by distraction, osteosynthesis method, the electroneuromyographic examination was performed in 28 patients of 16—62 years (average age — 40,1 ± 2,6 years) with pyramidal syndrome in late recovery or residual period, of the disease (severe brain injury cerebral stroke). The main trends in electroneuromyographic indice — "cerebrospinal index" — in patients during the replacement process of post-traumatic or simulated cranial vault bone defects using transosseous distraction osteosynthesis were analyzed. The specific features of the central nervous system responses to surgical treatment, age, etiology, the brain structures initial lesion severity and disease duration were studied. As the results of the research it was established that replacement of defects of calvarium bones by transosseous distraction osteosynthesis in patients with consequences of craniocerebral trauma or stroke had. more intensive positive influence on motor zones of cerebral cortex, that shows itself in increase of effectiveness of motor control, in middle age people, at traumatic etiology of disease, at moderate pyramidal insufficiency and. at remoteness of the disease up to 1 year. Obtained data is expedient to take into account at primary selection of patients for operative treatment.
