SCI Flashcards
A _ lesion is a lesion to the spinal cord where there is NO preserved motor or sensory function below the level of the lesion.
A COMPLETE LESION is a lesion . . .
An _ _ is a lesion to the spinal cord in which there may be scattered motor function, sensory function or both below the level of the lesion.
An INCOMPLETE LESION is a lesion to the
_ _ _ is an incomplete lesion that results from compression and damage to the anterior part of the spinal cord or anterior spinal artery. Mechanism of injury is usually _ _. There is loss of _ function, _ and _ sense below the lesion due to damage to the corticospinal and Spinothalamic tracts.
ANTERIOR CORD SYNDROME is an incomplete . . .
Mechanism of injury is usually CERVICAL FLEXION
There is loss of MOTOR function, PAIN AND TEMPERATURE sense below the lesion due to . . .
_ _ _ is an incomplete lesion usually caused by a stab wound, which induces hemi section of the spinal cord. There is _ and loss of _ and _ sense on the same side as the lesion due to damage to the corticospinal tract and dorsal columns. There is loss of _ and _ sense on the contralateral side of the lesion for damage to the lateral Spinothalamic tract.
BROWN SEQUARD SYNDROME is an incomplete . . .
There is PARALYSIS and loss of VIBRATORY AND POSITIONAL sense on the SAME SIDE
There is loss of PAIN AND TEMPERATURE sense on the- CONTRALATERAL SIDE
_ _ _ are injuries that occur below the L1 spinal leve wher the long nerve roots transcend. Can be _, however they are frequently _ due to the large number of nerves in the area. Is considered a _ _ injury.
CAUDA EQUINA INJURIES are injuries that . . .
Can be COMPLETE, however they are frequently INCOMPLETE due to the large. . . .
Is considered a PERIPHERAL NERVE injury
_ _ _ is an incomplete lesion that results from compression and damage to the central portion of the spinal cord. Mechanism of injury is usually _ _ that damages the Spinothalamic and corticospinal tracts and the dorsal columns.
CENTRAL CORD SYNDROME is an incomplete . . .
Mechanism of injury is usually CERVICAL HYPEREXTENSION that damages . . .
With central cord syndrome the _ _ present with greater involvement than the _ _ and greater _ deficits exist compared to _ deficits.
The UPPER EXTREMITIES present with greater involvement than the LOWER EXTREMETIES and greater MOTOR deficits exist compared to SENSORY deficits.
_ _ _ is a relatively rare syndrome that is caused by compression of the posterior spinal artery. It is characterized by loss of _, - _, and _. Motor function is _.
POSTERIOR CORD SYNDROME is relatively rare . . .
It is characterized by loss of PROPRIOCEPTION, TWO-POINT DISCRIMINATION and STEREOGNOSIS.
Motor function is PRESERVED.
How many grades are there on the ASIA scale?
5 (A-E)
Level _ on the ASIA scales is a complete spinal cord injury with no sensory or motor function preserved in the sacral segments (S4-S5)
Level A On the ASIA . . .
Key UE muscles tested during ASIA for C5? C6? C7?
C5- Elbow flexors (biceps, brachioradialis)
C6- Wrist extensors (ECRL, ECRB)
C7- Elbow extensors (triceps)
Key muscles tested during ASIA assessment for C8? T1?
C8- finger flexors (flexor digitorum profundus) at middle finger
T1- small finger abductors (adductor digiti minimi)
Key muscles tested during ASIA assessment for L2? L3? L4?
L2- hip flexors (Iliopsoas)
L3- knee extensors (quadriceps)
L4- ankle dorsiflexors (tibialis anterior)
Key muscles tested during ASIA assessment for L5? S1?
L5- big toe extension (extensor hallucis longus)
S1- ankle plantar flexors (gastroc, Soleus)
With ASIA B, _ but not _ function is preserved below the level of lesion AND includes the _ _ of _ and _ (can _ but cannot _ bowel function)
With ASIA B (incomplete), SENSORY but not MOTOR function is preserved below the level of the lesion and includes the SACRAL SEGMENTS of S3 and S4 (can FEEL but cannot CONTROL bowel function)
