[New approaches to the evaluation of functional state of afferent central nervous system pathways in patients with syringomyelia].
Functional state of both afferent and efferent pathways of CNS was studied with the method of magnetic stimulation (MS) in patients with syringomyelia. A control group contained 35 healthy individuals. The state of the efferent pathways was estimated by the time of the central motor conduction. The state of the afferent pathways of brain stem and spinal cord was analyzed by the latency of the motor responses of the orbicular muscle of the eye to MS of the spinal cord on the level of cervical and lumbar regions. The signs of the disorders in the conduction of the excitement through pyramidal pathways as well as through the afferent pathways of the spinal cord and the brain stem were registered in patients with syringomyelia. This observation allows to increase considerably the diagnostic range of MS.
