Diag. spinal cord lesions

Question 1

Diagnosing spinal cord lesions

Name types of tests to administer

and

clinical signs?

Answer 1

imaging:

(X-ray, CT, MRI)
- lumbar puncture (for testing CSF)

• lesion of half of spinal cord-> ipsilateral hemiplegia; ipsilateral loss of proprioception, vibration
• -> contralateral loss of pain and temperature
• lesion of whole spinal cord -> bilateral loss of motor and sensory below the lesion

Question 2

• Diagnosing spinal cord lesion*
• Dorsal colum-medial lemniscus pathway?*

Answer 2

• (ipsilateral)*
• Tactile discrimination, vibration, concious proprioception*

Question 3

=Diagnosing spinal cord lesion=

Ventral spinothalamic tract

Answer 3

(contralateral)

Light touch

Question 4

=Diagnosing spinal cord lesion=

Lateral spinothalamic tract

Answer 4

(contralateral)

Itch, pain, temperture

Question 5

=Diagnosing spinal cord lesion=

Dorsal spinoerebellar tract

Answer 5

(ipsilateral)

Unconcious proprioceptive, coordination of posture

Question 6

=Diagnosing spinal cord lesion=

Ventrl spinoerebellar tract

Answer 6

(contralateral)

Unconcious proprioceptive, coordination of posture

Question 7

=Diagnosing spinal cord lesion=

name 3 factors:

Answer 7

• Loss of ipsilateral sensory* and *proprioception below the lesion if located within the spinal cord
• Loss of contralateral sensory* and *proprioception if lesion is above brain stem

-Romberg sign (+) could infer the loss of proprioception
