The electroneuromyographic signs of recovering the function of lower limb muscles in the process of LIV vertebra spondylolisthesis by the technique of transcutaneous interbody spondylodesis

The data of 8 patients before treatment, in its process and after its completion have been analyzed with the purpose of neurophysiological objectification of the sensomotor deficit in the lower limb system of patients with LIV vertebra spondylolisthesis as well as with that of analyzing the depth and directionality of the changes in EMG-characteristics, induced by surgical treatment according to the technique of transcutaneous interbody spondylodesis. It has been established that the most marked EMG-signs of the sensomotor deficit for the spine disease mentioned are observed in the distal segments of lower limbs. By the moment of treatment course completion the destabilization signs of the functional status of the lower limb neuromotor system are noted, which represent a consequent reaction to correcting surgical intervention and prolonged postoperative deficit of functional loading. 6-24 months later the well-defined tendency towards normalization of global and stimulation EMG measurements has been determined with the exceeding of preoperative values and, in some cases, with the achievement of control (the normal patients examined) values
