Final answer:
Autonomic Dysreflexia occurs in 48-90% of those with spinal cord injuries at or above the Cervical (neck) level.
Step-by-step explanation:
Autonomic Dysreflexia occurs in 48-90% of those with spinal cord injuries at or above the Cervical (neck) level. The sympathetic division of the autonomic nervous system influences the various organ systems of the body through connections emerging from the thoracic and upper lumbar spinal cord.
Autonomic Dysreflexia is a serious condition that can result in a sudden increase in blood pressure, and it is more likely to occur when there is a spinal cord injury at or above the cervical level.
