Tetraspastic

from Wikipedia, the free encyclopedia
Classification according to ICD-10
G82.4 Spastic tetraparesis and tetraplegia
ICD-10 online (WHO version 2019)

The tetraspasticity is the paralysis of all four limbs (arms and legs) as a result of damage to the pyramidal tract of both sides. Typical lesion heights are the brain stem (for example in central pontine myelinolysis ) or the cervical medulla (for example in cervical myelopathy ).

Furthermore, in infantile cerebral palsy, tetraspasticity can occur as spastic tetraparesis . The origin of the pyramidal tract - the neurons of the primarily motor cortical field in the precentral gyrus of the frontal lobe of the cerebrum - was damaged around the time of birth. Then the head and trunk are often affected.

The transmission of motor impulses from the brain to the muscle takes place in several stages. First, the movement impulse is sent from the brain via the pyramidal tract to the spinal cord . If there is an interruption in this area (central or spastic paralysis ), this paralysis does not show muscle atrophy (muscle wasting), but increased muscle self-reflexes , typical pyramidal signs such as the Babinski sign and an increase in resistance to passive movement of the affected muscles (spastic increase in tone ).

Tetraspasticity as a symptom is also found in syndromes such as N-syndrome .
