[Pathological aspects of post-stroke muscle tone disorder: clinical-neuro-visual study]

We studied how different patterns of muscle tone disorders depend upon lesion site using CT. 111 patients not earlier 3 months after hemispheric stroke were studied. We showed the degree of spasticity to be determined by depth of hemispheric damage in relation to posterior limb of capsula intema. It also correlates with the degree of corticoreticular pathway damage. Even or irregular damage to this pathway which accompany pyramidal tract stipulates different patterns of spasticity, distribution and its interaction with structure of hemiparesis. Degree and structure of post-stroke muscle tone disorders after 3 months from the onset of stroke is depend on hemispheric damage but do not depend on the duration of recreative or residual period of the disease. It can be applied in medical expertise that pattern and prominence of post-stroke muscle tone disorders 3 months after stroke onset depend on lesion location, but not on the length of recovery period or period of residual changes.
