An SCI can cause reduced feeling and movement in certain parts of the body. Every SCI is different. Every person’s outcome is different as well. This sheet goes over some basic things to know about your level of injury. Ask your doctor to tell you more about your case.
The spine has 33 bones (vertebrae). These bones are grouped into four sections:
Cervical (C): Neck
Thoracic (T): Upper back
Lumbar (L): Lower back
Sacral (S): Pelvis
The spinal cord runs through the center of the vertebrae from the base of the brain to the lower back. It contains many nerves that control movement and feeling in the body. The nerves exit and enter the spinal cord through spaces between the bones of the spine. There are:
8 cervical nerves: C1 through C8
12 thoracic nerves: T1 through T12
5 lumbar nerves: L1 through L5
5 sacral nerves: S1 through S5
An SCI is named with a letter for the section of the spine and a number for the nerve that was injured. The level of injury determines which parts of the body are affected. In general, movement and feeling are lost below the level of injury.
An SCI can be complete. This means there is total loss of movement and feeling below the level of injury. Or an SCI can be incomplete. This means there is some loss of movement, feeling, or both below the level of injury. To assess the severity of your injury, your doctor may use the ASIA scale. (See the box below for a link to this resource.) With this scale, a grade (ranging from A to E) is given to explain the completeness of an injury. The grade is based on the results of various sensory and motor function tests. Your doctor can tell you more about the grade of your injury and how often you’ll be tested.
Depending on the level and severity of the injury, a person with an SCI will have varying degrees of feeling and movement in their body. Other body functions, such as breathing and bowel and bladder control may be affected as well. Some people with SCI may be able to do most personal care and daily activities on their own. Others may need more assistance. This can include help with certain tasks, such as dressing, eating, driving, and moving around.
Note that outcomes are different from person to person, even with the same level of injury. Many factors are involved. The grade and severity of your injury may change over time. Your abilities and function may change too. After the initial period of adjustment, many people with all levels of SCI report a high quality of life. Work with your doctor and healthcare team to learn what outcomes you might expect with your injury, and what goals to work toward.
