In the present paper, the significance of main parameters of transcranial magnetic stimulation (TMS) in cervical spine stenosis (CSS) confirmed by MRI was assessed. Forty two patients (26 men and 16 women, mean age 49±7.4 years) and a control group comprising 9 men and 7 women (mean age 44±2.1 years) were examined. The Japanese Orthopaedic Association (JOA) score was used for neurological assessment. It was shown that the duration and polyphasy of MEP were the most informative  parameters on the early stage of CSS, even in the absence of MRI changes and in normal values of the central motor conduction time (CMCT). Increase of CMCT was seen in extended SCS. TMS may be regarded as a valuable tool in the assessment of functional state of subclinical and clinically evident cervical spondylotic myelopathy.
