Abstract
Objective. To assess the influence of etiological factor on the intensity of ENMG manifestation of sensory-motor deficit in patients with lumbar spondylolisthesis.
Material and Methods. Complex neurophysiological examination (total EMG, M-responses, H-reflexes, transcranial evoked potentials) was performed in 88 patients aged 13 to 77 years with spondylolisthesis of different etiology: dysplastic (Group I) – 11 patients, isthmic (Group II) – 42, degenerative (Group III) – 31, and traumatic (Group IV) – 4.
Results. The study showed that general (sensory-motor deficit index – SMDI) and particular ENMG characteristics of sensory- motor deficiency depend on the etiology of the spine disease. Namely the total SMDI, calculated for each patient as a mean value of relative ENMG indices, expressed as a percentage of control group (healthy subjects), was 86.5 ± 5.6 % in Group I, 91.6 ± 2.8 % in Group II, 77.6 ± 2.9 % in Group III, and 88.3 ± 10.2 % in Group IV.
Conclusion. The most pronounced ENMG manifestations of neurological symptoms were observed in patients with degenerative spondylolisthesis, the least – in ones with isthmic spondylolisthesis.
