A complete spinal cord injury means that there is no movement or sensation below the level of the injury. In a complete injury, both sides of the body are equally affected. Complete spinal cord injuries will result in complete paraplegia or complete tetraplegia.
Complete paraplegia is a condition that results in permanent loss of movement and sensation at the T1 level or below. At the T1 level there is normal hand function, and as the levels move down the spinal column improved abdominal control, respiratory function, and sitting balance may occur.
Some patients with complete paraplegia have some degree of trunk function, and can stand or even walk short distances with supportive leg braces and a walker. In this situation, the abdominal muscles are used the propel the paralyzed legs forward, while body weight is supported by a walker.
Complete tetraplegia is a condition that results in permanent loss of movement and sensation in all four limbs. Spinal cord injuries that result in complete tetraplegia most often occur at levels C1 through C8. The degree of functionality is a direct result of where the injury to the spine occurred.
