In typical cases, multiple protruzy discs at lumbar level in PS in mielografii direct projection get anywhere in the world. picture "osinoy waist" and the side-washing blackboards "[40]. A survey of patients with TS may also include analysis of somatosensory evoked potentials (SSVP) [38]. Korotkolatentnye SSVI a thick mielinizirovannymi fibres, that regardless of the genesis defeat roots (mechanical factor, or ischaemia) threatened in the first place. This is reflected in the reduction of the amplitude of early components SSVP. The situation Flexner in PS to a greater or lesser extent may vary clearance spinal canal and pressure and epiduralnom space. Study SSVP produced by the dynamic samples in the razgibaniya usually determines the lower amplitude of early components VP. The amplitude of early components may change immediately after the change of posture, which suggests that mechanical genesis of such changes. Changes same amplitude of early components VP caused disease occur after a latent period. Currently, the problem of choosing tactics treatment PS, in particular surgical, remains open [51]. Most authors feel it necessary to adopt a rapid intervention in cases of progressive course of the disease and the lack of economies of conservative treatment for 3 to 6 months
