Abstract


Purpose. To study the effect of the technique of transosseous distraction cranial osteosynthesis on the functional condition of the neuromotor system in patients with the consequences of hemispheric insult and those of severe craniocerebral injury.
Materials and Methods. The analysis of the dynamics of some electroneuromyographic values made; the values obtained by testing limb muscles in 28 subjects in the residual period of the disease.
Results. During the study this surgical treatment has been revealed to provoke the destabilization of the motor system functional condition the signs of which observed up to the control periods of examination. The analysis of the data obtained within the control periods evidences that positive dynamics of cerebrospinal indexes is the most marked in the long-term postoperative period and by the leads in the paretic upper limb. In this case significant variability is observed concerning the degree of reactive changes induced by cranial osteoplasty.
Conclusion. The increase in effectiveness of the motor controlling the paretic limb muscles has been determined electrophysiologically in patients with cerebral alteration consequences while being treated by the technique of transosseous distraction cranial osteosynthesis.
