Levada O. The peculiarities of clinical structure of motor deficit in patients with different localization of hemispheric stroke according to computed tomography data

Clinical, computed tomographical, electromyographical investigation was carried out in 111 patients after hemispheric stroke not earlier 3 months following the outset of the disease. That the degree of poststroke paresis was depended by depth of corticospinal tract damage and the degree of poststroke spasticity was depended by depth of corticoreticular tract damage. Proportional or disproportional damage of thees tracts determines the variants of paresis and spasticity distribution in defeat extremities. Decrease of depth of longterm and homosinaptic depression of H-reflex increases with the depth of hemispheric damage in relation to posterior limb of capsula interna. Forming of pathological motor syndromes is depended by combinations of defeat the motor hemispheric structures. Damage of dominant hemisphere is more important for origin of hard motor deficit in upper extremity. Proposed local-volume index allows to evaluate the influence of volume factor to degree and peculiarity of motor disorders more exact. Elaborated clinical-computed-tomographical graduation of the poststroke cysts allows to objectivise the degree and peculiarities of clinical structure of motor deficit on the early recreative stage of the disease.
