[Functional state of the spinal cord in syringomyelia and tuberculous spondylitis with spinal disorders].

In patients with syringomyelia and tuberculous spondilitis accompanied by spinal disturbances (which are in accordance with clinical data considered as models with prevalent signs of disintegration and irritation in the spinal cord) the authors studied separate parameters of the H-reflex and 2 functionally different muscles: m. gastrocnemium and m. soleus. It was possible to show certain differences in the parameters of the H-reflex between the two groups of patients and between the indices of the 2 studied motoneuron pools within each group. The report contains some ideas in relation to the possible causes of these phenomena.
