Question 16

Incomplete SCI Syndromes:

Brown-Sequard Syndrome

Answer 16

**CLASSIC TEST QUESTION**

Cause

• bullet/stabbing = leads to hemisection

Ipsilateral loss of

• proprioception
• deep & discriminative youch
• vibration
• motor function

Contralateral loss of

• pain
• temp
• crude touch

typically won’t see TRUE, may see pieces of this syndrome

Question 17

How do you classify level of injury?

Answer 17

American Spinal Cord Association (ASIA) Index

• Test key muscles in 10 paired myotomes
• Rostral-caudal sequence
• 2 motor socres: Right & Left
• Motor Level = level where muscle grade = 3 & next most rostral muscle = 5 or higher
• Sensory level (deermatomes) may be different from motor level
