Tetraplegia (formerly called quadriplegia) refers to an injury to the cervical (neck) section of the spinal cord. It can involve either partial or complete loss of movement and/or feeling in the head, neck, shoulders, upper chest, arms, and legs. Paraplegia refers to an injury in the thoracic, lumbar, or sacral sections of the spinal cord. It can involve either partial or complete loss of movement or feeling in the chest, stomach, hips, legs, and feet. Tetraplegia is slightly more common than paraplegia.
