[Electrophysiological mechanisms of spinal systems plasticity in people with dysfunctions of the locomotor system]

The reflex motor responses of some bilateral muscles of hip, shin and foot were evoked by percutaneous surface electrical spinal cord stimulation at the lumbosacral levels (T11-L3) in the patients with marked lumbosacral radiculopathy caused by spinal osteochondrosis and in neurologically healthy physically inactive individuals, as well as in healthy qualified athletes and athletes with knee joint injuries. There was used the technique of registration of posterior root-muscle reflexes. In the subjects with neurologic pathology and in the group of athletes with knee joint injuries the data demonstrated similar signs of plasticity of spinal neural circuits, innervating the muscles of the low extremities.
