Spinal cord injury hypertonic spasticity may be a manifestation of damage to the pyramidal tract.
Spinal cord injury results in damage to the pyramidal tract, resulting in severance of the upward and downward nerve conduction pathways, with the lower nerve centers of the spinal cord remaining intact below this plane of injury.
As the upper nerve conduction pathway is cut off, the lower neurons cannot receive the inhibitory stimulation from the higher extrapyramidal system, resulting in the continuous, excessive and abnormal excitation of the lower neurons, which leads to the manifestation of increased muscle tone and spasticity in the limbs below the injury level.
The spinal cord injury leads to increased muscle tone spasm of the limbs, which is commonly seen in higher spinal cord injuries, such as cervical cord injuries, which often indicates that the spinal cord injury is more serious.
Spinal cord injury hypertonic spasticity serious people timely medical treatment, under the guidance of the doctor targeted treatment.
