Q

What synergy do you test for first in UE? Why?

A

You place them into the flexion synergy and test the EXTENSION synergy first - because the flexion synergy is more common you do not want it to dominate and make them unable to complete extension

Q

What synergy do you test for first in LE? Why?

A

You place them into the extension synergy pattern and test the FLEXION synergy first - because the extension synergy is more common you do not want it to dominate and make them unable to complete flexion

Q

What is the anatomy of the visual pathway

A

Light hits the back of retina
Optic nn starts
Some cross @ optic chiasm, others do not
From there travel through optic tract to lateral geniculate nucleus (LGN)
They synapse w/optic radiation that course through to occiput (primary visual cortex)
Through Parietal or Temporal lobe

Q

What is CL homonymous hemianopsia

Study These Flashcards
A

Loss of one visual field in both eyes (ex damage on R side would cause loss of Left visual field on both eyes)

21
Q

What is CL lower quadratic anopsia

Study These Flashcards
A

Loss of CL lower quadrant due to damage of optic radiations through the parietal lobe

22
Q

What is CL upper quadratic anopsia

Study These Flashcards
A

Loss of CL upper quadrant due to damage of optic radiations through the temporal lobe

23
Q

What is CVA

Study These Flashcards
A

A sudden loss of neurological function caused by an interruption of the blood flow to the brain
