Abstract

Objective. Investigation of the neck arterial and venous blood flow peculiarities associated with instability in the neck vertebral motional segments (VMS) and influence of the soft tissues manual therapy on it. Material and methods. Dopplerographic test of blood flow in vertebral arteries (VA), scalp vein and neck was performed in 50 patients at the age of 20-40 with cervico-occipital pain syndrome before and after head rotation. Respiratory samples with vasodilatation index (VI), vasoconstriction (VC) and vaso motor reactivity (VMR) for the basilar artery (BA), VA, posterior and medial cerebral arteries were performed in all patients. The patients were examined three times: before manual therapy and immediately after the course and in 6 months period after the course. Results. Significant increase of CPB in VA associated with pain syndrome was detected. After manual therapy course we noted the decrease of degree of blood flow asymmetry, decrease of peripheral resistance and evidence response on pendulum test in VA, decrease of CPB and VMR in VA, BA and posterior cerebral arteries; decrease of the number of located venous trunks and reduction of blood flow speed. All changes are saved during 6 months after the end of treatment. Conclusions. Firstly, increase of peripheral resistance and hemodynamic reserve in vertebral-basilar system (VBS) due to constrictor component for unstable cervical motor segments and asymmetric changes of linear blood flow velocity (LBFV) in VA during pendulum test and formation of venous disgemias in venous systems of head and neck. Secondly, soft tissue methods of manual therapy are not only effective methods of treatment of instability of cervical spinal motion segment but they contribute to normalization of vascular responses in VBS and improvement of venous return with long-term effect of preservation.
