[Dynamic 4-zone sensometry in vertebrogenic lumbosacral radiculitis and lumboischialgia].

A total of 193 patients were studied by means of "Amplipuls" apparatus for the thresholds of tissue sensitivity and interthreshold intervals in four zones (the involved radicle, affected vertebral segment and symmetrical points of the "healthy" side) using a modified Sangailo's sensometry. The authors have identified differences of the threshold characteristics in all zones which depended on the severity of damage to the sensory nerves (according to the clinical findings) and the presence or the absence of attendant neurotic manifestations. Differences were revealed both during the initial examination and after the treatment. Practical significance of the results of the study is emphasized.
