|A||Complete||No motor or sensory function is preserved in the sacral segments S4–S5.|
|D||Incomplete||Motor function is preserved below the neurological level, and at least half of key muscles below the neurological level have a muscle grade of 3 or more.|
|E||Normal||Motor and sensory function are normal.|
How do you know if a spinal cord injury is complete or incomplete?
If you have motor and sensory functions with this part of the test, your injury is considered incomplete. That means your brain can still receive nerve signals from the end of the spinal cord. If you cannot contract the anal muscle or feel sensation around the anus, the injury is classified as complete.
What is the ASIA scale?
What is the ASIA Impairment Scale? The American Spinal Injury Association Impairment Scale is a standardized neurological examination used by the rehabilitation team to assess the sensory and motor levels which were affected by the spinal cord injury.
What does Asia B mean?
B = Incomplete: Sensory, but not motor, function is preserved below the neurologic level and extends through sacral segments S4-S5. C = Incomplete: Motor function is preserved below the neurologic level, and most key muscles below the neurologic level have a muscle grade of less than 3.
What is an incomplete spinal cord injury?
An incomplete injury means that the ability of the spinal cord to convey messages to or from the brain is not completely lost. Additionally, some sensation (even if it’s faint) and movement is possible below the level of injury.
Can a complete spinal cord injury become incomplete?
A complete spinal cord injury occurs when a person loses all sensory and motor function below the level of the spinal cord injury. When a person with a spinal cord injury retains some function below the level of the injury, they have an incomplete spinal cord injury.
Can you recover from an incomplete spinal cord injury?
With many injuries, especially incomplete ones, the individual may recover some function as late as 18 months after the injury. In very rare cases, people with spinal cord injury will regain some functioning years after the injury.
What is C4 spinal injury?
A C4 spinal cord injury occurs when damage is dealt about mid-way down the cervical spinal cord — the topmost portion of the spinal cord that is located in the neck and upper shoulders.
What does tetraplegic mean?
Tetraplegia (sometimes referred to as quadriplegia) is a term used to describe the inability to voluntarily move the upper and lower parts of the body. The areas of impaired mobility usually include the fingers, hands, arms, chest, legs, feet and toes and may or may not include the head, neck, and shoulders.
Which scale is most commonly used to classify the severity of spinal cord injury?
3.1 Injury severity and phase of injury
The American Spinal Injury Association Impairment Scale (AIS) is widely used to classify the severity of injury in SCI individuals, with motor complete (AIS grade A and grade B), motor incomplete (AIS grade C and grade D), or normal (AIS grade E) (Kirshblum et al., 2011).
What is AIS D spinal cord injury?
AIS D is assigned if half or more of the key muscles below the neurological level of injury have a grade ≥ 3/5. Unlike the A, B, C and D classifications, an AIS E classification implies the presence of a spinal cord injury but without detectable neurological deficits.
What is Brown sequard syndrome?
Brown-Sequard syndrome (BSS) is a rare neurological condition characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side.
How are spinal cord injuries named?
An SCI is described by its level, type, and severity. The level of injury for a person with SCI is the lowest point on the spinal cord below which sensory feeling and motor movement diminish or disappear. The level is denoted by the letter-and-number name of the vertebra at the injury site (such as C3, T2, or L4).
How long does it take to recover from incomplete spinal cord injury?
When it comes to incomplete spinal cord injury recovery, most people experience the greatest amount of recovery within the first 6 months to a year following their injury. After a spinal cord injury, the spinal cord experiences a temporarily heightened state of plasticity, which makes it easier to relearn functions.
