On the basis of the study of the results of distractional stretching of peripheric nerves, and as well as their comparison with the results of the treatment using plaster bars, a number of advantages of the apparatus method is revealed in replacing nerves defects. These advantages allow to improve significantly the results of the treatment of patients concerning the recovery of sensory and motor functions of the injuried peripheric nerve.

The effect of immobilization of the lower limb on the state of the soleus muscle center and its electrical activity was studied. Using the H-reflex technique, a decrease in the reflex excitability of motoneurons and an increase in recurrent inhibition on the immobilization side compared to the intact side were established. A decrease in the amplitude of the M-response of the immobilized soleus muscle was also found.

The state of peripheric and central parts of neuromuscular system in patients with traumas of nerves of the forearm after the operations is examined by electrophysiologic methods. The changes of motor and central caused responces of the short abductor of the first finger are detected, pointing at the participation of median and ulnar nerves in the reinnervation of this muscle and the existence of functional shifts in the state of motor centers of the muscles of injured and uninjured limbs.

It is known that traumatic spinal cord injury leads to a number of structural and functional changes. As a result of trauma, the spinal cord is cut off, compressed and softened by central hemorrhagic necrosis, and local damage to the axons is determined within a few hours.
