Evaluating Spinal Cord Injury Levels of Injury
After a spinal cord injury, all the nerves above the level of injury keep right on working.
The site of the injury is like a washout on a road that blocks traffic from going either way.
The spinal cord nerves at the site of the injury and below can no longer send messages between the brain and parts of the body they connect with as they could before the injury.
The washout may be complete, or it may be partial, so that some traffic can get through.
A doctor examines the individual to evaluate the location and extent of damage to the spinal cord.
An X-ray may show where the damage to the vertebrae is located.
The doctor does a pin prick test (just what it sounds like) to see what feeling the person has in various parts of the body.
The doctor will ask the patient what parts of the body s/he can move, and test the strength of important muscle groups.
These examinations help the doctor and treatment team know what nerves and muscles are still working.
The level of injury refers to the lowest point on the spinal cord below which there is an impairment or absence of feeling and/or movement.
The higher the spinal cord injury is on the vertebral column, the more extensive the injury's effect will be on the body's ability to move and feel.
A lower level of injury will mean the person retains more movement, feeling and voluntary control of the body's systems.
For example, a person with a C-5 level of injury has a decrease or loss of feeling and movement below the base of the neck.
An injury at the L-1 level means the individual has a decrease or loss of feeling and movement below the first lumbar spinal cord segment, in the low back.
A person whose injury was at L-1 would have more feeling and movement than someone with a C-5 level of injury.
Tetraplegia refers to the condition of a person with a spinal cord injury that is at a level from C1 to T1.
In tetraplegia, formerly called quadriplegia, the person sustains a loss of feeling and/or movement in their head, neck, shoulder, arms and/or upper chest.
Paraplegia is the general term for the loss of feeling and/or movement in the lower parts of the body.
The body parts that may be affected are the chest, stomach, hips, legs and feet.
An injury anywhere from T2 down to S5 results in paraplegia.
Levels of injury and affected areas Neck: Cervical (neck) injuries usually result in quadriplegia.
C-1 to C-4: These very high injuries (C-1, C-2) can result in a loss of many involuntary functions including the ability to breathe.
A person with an injury at this level will require a mechanical ventilators or diaphragmatic pacemakers.
C-5: C-5 injuries often result in loss of control at the wrist or hand; shoulder and biceps control are not affected.
C-6: C-6 injuries generally leave a person with wrist control, but no hand function.
C-7 and T-1: Individuals with C-7 and T-1 injuries can straighten their arms but may have dexterity problems with the hand and fingers.
T-1 to T-8: Injuries at the thoracic level and below result in paraplegia, with the hands not affected.
At T-1 to T-8 there is most often control of the hands, but poor trunk control as the result of lack of abdominal muscle control.
T-9-T12: Lower T-injuries (T-9 to T-12) allow good truck control and good abdominal muscle control.
Sitting balance is very good.
Lumbar and sacral injuries yield decreasing control of the hip flexors and legs.
Complete or incomplete injury The amount of feeling and movement that an individual retains also depends on whether the injury is complete or incomplete.
A complete injury, usually caused by a complete severing of the spinal cord means there is no motor or sensory function in the area.
Some people with an incomplete injury may have feeling, but little or no ability to move.
Others may have movement and little or no feeling.
Every incomplete spinal injury is unique because the amount of damage to each person's nerve fibers is different.
Because of these individual variations it is impossible to accurately predict how much of an individual's sensory and motor function will return.
An individual whose injury is incomplete generally stands a greater chance of recovering of some or all his/her motor and sensory function.
If the negligence or misconduct of another person, corporation, or government entity contributed to your SCI, you may be able to file a claim for damages such as medical costs, both current and future, loss of earning power, and loss of the lifestyle and mobility you enjoyed before the injury.
If you believe you have a claim, you should consult an experienced spinal cord injury attorney as soon as possible.
