The most serious complication of spinal cord injury can occur as damage to the respiratory muscles, causing paralysis of the respiratory muscles and respiratory failure, which may lead to death, and is most commonly seen in cervical cord injuries. At the same time, there may be sensory or motor dysfunction of the limbs, with various discomforts such as numbness, numbness, pain, etc. Sensory planes may occur, as well as urinary and fecal disorders, including urinary and fecal retention and urinary and fecal incontinence. In case of lumbar medullary injury, respiratory muscle paralysis and respiratory failure do not usually occur, and may be manifested as sensory deficits below the lesion segments, with numbness and pain. There may also be motor dysfunction or sensory impairment of both lower limbs without abnormal sensory or motor function of the upper limbs.
