Relationship of Cerebral Hemodynamics and Cerebral Bioelectrical Activity in Patients with Cervical Osteochondrosis

Abstract

Introduction . Osteochondrosis of the cervical spine is a very common disease that causes a significant decrease in the quality of life of patients. In the case of pronounced changes in the cervical spine with osteochondrosis, there is a violation of blood circulation in the cerebral cortex, which leads to pronounced clinical symptoms. The aim of this study was to identify a correlation between bioelectrical activity and cerebral hemodynamics in patients with osteochondrosis of the cervical spine. Materials and methods . The examination involved 25 patients of the neurosurgical department who received conservative treatment for exacerbation of osteochondrosis of the cervical spine, and 25 volunteers without a history of diseases of the spine and joints. The cerebral bioelectrical activity and blood flow indicators were recorded in the pool of the common carotid and vertebral arteries. Results . In the main group and the clinical comparison group, the rheographic index and the peripheral vascular resistance index were studied, which characterize both the volume pulse blood filling of the vascular bed and the tone of small and medium caliber arteries. At the same time, the EEG rhythm indices were analyzed: а -, в -, S-, and в -waves. An analysis of the intersystem interaction of bloodflow indices and the biopotentials of the cortical rhythm of the brain in the main group showed a mismatch in the intra-system connections, which corresponds to the period of the general stress of the body. An analysis of the correlation between the indicators of electroencephalography and rheoencepha-lography in the control group revealed a stable system of correlation between the indicators, showing intersystem and intrasystem consistency and reflecting a high level of reserve capacity of the body and the state of steady adaptation to adverse factors. Conclusion . The use of simultaneous recording of cerebral hemodynamics and brain biopotentials in patients with osteochondrosis of the cervical spine will allow clinicians to correctly assess the functional state of the central nervous system and to prescribe adequate treatment in a timely manner.
