What is the ASIA Impairment Scale?
What is the ASIA Impairment 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.
How is motor level calculated in Asia?
2. Determine motor levels for right and left sides. Defined by the lowest key muscle function that has a grade of at least 3 (on supine testing), providing the key muscle functions represented by segments above that level are judged to be intact (graded as a 5).
What is neurological level in Asia scale?
The ASIA Impairment Scale is follows the Frankel scale but differs from the older scale in several important respects. First, instead of no function below the injury level, ASIA A is defined as a person with no motor or sensory function preserved in the sacral segments S4-S5.
How does the ASIA scale work?
The ASIA Impairment Scale assigns the SCI a grade based on its severity. Grades range from A to E, with A being the most severe injury and E being the least severe. Complete sensory or motor function loss below the level of injury. Sensation is preserved below the level of injury, but motor function is lost.
What does Asia C mean?
ASIA C: Incomplete, motor function is preserved below the neurological level of injury, but more than half of the key muscles below the level have a muscle grade less than 3 (i.e. unable to move against gravity)
How do you score dermatome?
Each sensory dermatome is given a score of 0, 1 or 2. A light touch sensory score of 0 means absent sensation in that dermatome. A score of 1 is given for altered sensation when compared with the face, which serves as the reference point. A score of 2 is given if the sensation is normal, or the same as the face.
How many sensory dermatomes are there in AISA?
Light touch sensation is tested using the stroke of a cotton tip swab <1cm, while sharp/dull or pin prick sensation is tested using a safety pin in 28 dermatomes from C2 to S4-5 on each side. A diagram of the sensory dermatomes can be found on the AISA website (www.asia-spinalinjury.org). Each sensory dermatome is given a score of 0, 1 or 2.
What are the scores on the ASIA Impairment Scale?
Motor score: 10 key muscle groups tested in SUPINE position and scored 0 to 5 or NT (not tested). 7. Sensory score: 28 dermatomes tested for Light touch/LT (posterior column – use cotton tip applicator) and Pin Prick/PP (spinothalamic tract – use safety pin) and scored 0 to 2 or NT (not tested).
Where can I find diagram of sensory dermatomes?
A diagram of the sensory dermatomes can be found on the AISA website ( www.asia-spinalinjury.org ). Each sensory dermatome is given a score of 0, 1 or 2. A light touch sensory score of 0 means absent sensation in that dermatome. A score of 1 is given for altered sensation when compared with the face, which serves as the reference point.
Is there an ASIA scale for spinal injury?
ASIA impairment scale for spinal injury. A.Prof Frank Gaillard ◉ ◈ et al. The American Spinal Injury Association (ASIA) was developed by the American Spinal Injury Association in 2006, and at the time of writing (July 2016), remains the most widely used scale.
