What is tetraplegia?
Involvement of all four extremities
What level injuries result in tetraplegia?
C1-C8
What is paraplegia?
Involvement of legs and part of trunk
What level injuries result in paraplegia?
T1-S5
What are the three incomplete clinical syndromes?
- Anterior cord syndrome
- Central cord syndrome
- Brown-Sequard syndrome
What is the ASIA?
Scale developed to determine level and severity of a spinal cord injury - standardized motor and sensory examination
When is ASIA performed?
After spinal shock resolves
Why should you perform the exam?
- Determine where spinal cord was injured
- May be different than what was viewed on MRI or CT
- Main test to determine level of injury, severity, and may provide insight into recovery expectation
What are the 5 steps to performing the ASIA?
- Determine sensory levels for R and L extremities
- Determine motor levels for R and L extremities
- Determine neurological level of injury
- Determine whether injury is complete or incomplete
- Determine AIS grade
Describe the light touch assessment
28 key sensory points, compare to face
What is a 2 on the light touch exam?
Intact
What is a 1 on the light touch exam?
hyper or hypo compared to face
What is a 0 on the light touch exam?
Absent
Describe how to perform sharp/dull
3 times at each spot
What is a 2 on the sharp/dull exam?
Intact - accurately identifies sharp vs dull
What is a 1 on the sharp/dull exam?
Diminished - accurately identifies but is hyper or hypo compared to face
What is a 0 on the sharp/dull exam?
Absent - cannot identify, or < 80% of the time
Describe how to perform a motor assessment for ASIA
10 key muscles, classify MMT grade 0-5, do all muscles in upper and lower extremities
What is the pt position for the ASIA assessment?
Supine
How do you determine the motor level of a pt?
The lowest level is a 3/5, and then level directly above needs to be 5/5
If there is not a clinically testable myotome, how do you determine the motor level?
Use the sensory level
How do you assess anal sensory and motor function?
Voluntary anal contraction, deep anal pressure, dermatome assessment
What are the three qualifications for determining the neurological level of injury?
Most caudal segment with
1. Intact sensation
2. Muscle function of at least 3/5
3. Rostral segments must also have intact sensation and at least 4/5 muscle function
What are the four requirements to be classified as a complete SCI?
- No sacral sparing
- No voluntary anal contraction
- All S4-S5 are 0
- No deep anal pressure
What is considered to be an incomplete SCI?
Sacral sparing
What is the zone of partial preservation?
Areas of intact motor and/or sensory function below the ipsilateral motor or sensory level in a patient who does NOT have sacral sparing
What SCI population can have a zone of partial preservation?
Complete injuries
What is AIS A?
Complete SCI, record the zone of partial preservation
What is AIS B?
Motor complete (sacral sparing) - no voluntary anal contraction OR no motor function more than three levels below motor level on a given side
What is AIS C?
Less than half of the key muscles below neurological level are 3/5 or better
What is AIS D?
At least half of the key muscles below neurological level are 3/5 or better
