Dynamics of neurophysiological parameters in patients with consequences of cervical spine injury under epidural electrostimulation
Keywords:cervical spine trauma, epidural electrostimulation, diagnostics, evoked motor potentials
Introduction. Method of epidural electrostimulation (EES) is considered to be one of the most promising areas of renewing surgery of the spinal cord.
Materials and methods. The results of treatment of 80 patients (90% — men, 10% — women) with consequences of cervical spine injury of different severity were analyzed. Clinical and neurological, neurophysiological (NPh) methods, including electroneuromyography (ENMG) and motor evoked potentials (MEP) registration were used.
Results. Using EES method in patients with spinal trauma consequences the improvement of cortical-spinal conductivity was achieved, in 76 (95%) — certain renewing of movement in a particular group of muscles. A direct correlation between results of motor recovery after EES according to clinical evaluation and MEP indices was found (r=0,6, P <0,01) in patients from different groups.
Conclusions. Clinical and NPh tests allow to estimate quantity of spinal cord conducting functions disorders before operation and provides objective criteria for evaluation of surgery effectiveness in patients with consequences of cervical spine injury.
