The electroneuromyographic characteristics of the neuromuscular system condition of the lower limbs in patients with herniated LIV-V in tervertebral disk in the process of surgical treatment

The data of 25 patients with the compression-and-ischemic syndrome of lumbar localization, underwent surgical treatment for LIV-V intervertebral disk herniation using interlaminectomy technology, have been analyzed before the treatment, in its process and after its completion for the purpose of pre- and postoperative neurophysiological evaluation of amyotrophy manifestation degree in lower limb system of such patients. The aggravation of functional insufficiency has been observed postoperatively in the system of regulation of the voluntary controlling the tension of the lower limb muscles tested and their motor innervation, that is probably a reaction of central and peripheral sensomotor structures to surgical intervention performance. In the nearest months (3-11) after treatment the tendency has been revealed towards EMG-characteristic restoration up to the level, which exceeds the preoperative one in some muscles. The technique of EMG-evaluation of the neuropathic pain syndrome observed at the moment of examination has been proposed.
