SCI

Question 0

motor level

Answer 0

Most distal segmental level which has muscle strength grade of at least “3” and above level has grade of “5”

Question 1

Definition

Answer 1

neurological damage of the spinal cord following trauma.

Question 2

neurological level

Answer 2

Most distal segmental level which has a normal sensory and motor function.
e.g. neurological level C5 is sensory and motor are normal at C5 level and above.

Question 3

complete lesion

Answer 3

no sensation or motor function below the neurological level

Question 4

incomplete lesion

Answer 4

some sensation or motor function below the neurological level includes the lowest sacral segment

Question 5

ASIA- A

Answer 5

Complete - No motor or sensory function in S4 - S5

Question 6

ASIA - B

Answer 6

Incomplete - some sensation in sacral segments (S4-S5)

Question 7

ASIA - C

Answer 7

Incomplete - got sensation and motor function in sacral segments.
Also has LESS than 3/5 strength (i.e. 2/5) in the more than half of the key muscle groups below the neurological level

Question 8

ASIA - D

Answer 8

Incomplete - got sensation and motor function in sacral segments.
Has 3/5 or MORE strength in at least half of key muscle groups below the neurological level

Question 9

ASIA - E

Answer 9

Normal motor and sensory function

Question 10

True or False
In Brown Sequard, the clinical presentation is ipsilateral loss of pain and temperature and contralateral loss of muscle strength.

Answer 10

False.
contralateral loss of pain and temp, ipsilateral loss of muscle strength. i.e. lateral thalamic tract decussate at the same level
i.e. Descending pathway (e.g.Lateral Corticospinal
tract) decussate in the brain stem.

Question 11

True or False
In the complete lesion, reflex will be lost at the segmental level of lesion and have exaggerated reflex below the level of lesion

Answer 11

True
reflex will be ABSENT at the same level of lesion
and exaggerated reflex below the level of lesion due to loss of DESCENDING INHIBITION
