neuro tx quiz 1 Flashcards
1st degree nerve damage - compression, local conduction block, no structural damage to axon or tissue distal to lesion - only motor loss is ______
neuropraxia
which area of the brachial plexus is affected by Klumpke’s Paralysis
LOWER brachial plexus - C8-T1
presents as claw hand
what is the secondary syndrome associated with Klumpke’s
Horner’s Syndrome
- constriction of pupil
- eyelid drooping
- loss of sweating to one side of the face and neck
- recession of eyeball into orbit
what part of the brachial plexus is injured with Erb’s Palsy
UPPER brachial plexus C5-C6
what presentation is typically seen with Erb’s palsy
“waiter’s tip”
shoulder adducted & internally rotated
elbow extended
forearm pronated
wrist & fingers flexed
order of areas to test when doing the ULTT’s from first to last
- shoulder
- elbow
- forearm
- wrist
- fingers and thumb
- shoulder
- cervical spine
Froment’s sign = What nerve injury
ulnar nerve injury
Claw hand, bishop’s hand is what nerve injury
ulnar nerve injury
ape or oath hand = what nerve injury
median
what is the prognosis for neuropraxia
GOOD
week-month recovery
what is the prognosis for axonotmesis
GOOD
prognosis for neurotmesis
POOR
2nd degree - prolonged, severe compression causing lesion followed by degeneration of axons distal to injury
sensory, motor, autonomic losses, regeneration at end is still possible
axonotmesis
complete / partial severance of nerve trunk including endoneurial tube, sensory, motor, autonomic loss
no clear pathway to orient regenerating axons
neurotmesis
flaccidity =
motor loss
paresis =
weakness
anesthesia =
sensory loss
paresthesia =
sensory impairment
dysesthesia =
pain
neuritis
inflammation of a nerve, sheath and CT are affected
neuralgia =
nerve pain
what does ULTT1 test
median, ant interosseous
what does ULTT2 test
median, musculocutaneous, axillary
what does ULTT3 test
radial
what does ULTT4 test
ulnar
the active process of degeneration that results when a nerve fiber is cut or crushed and the part of the axon distal to the injury degenerates is called ______
Wallerian Degeneration
peripheral nerves can regenerate if ____
the cell body is intact
if the lesion site is too close to the cell body and it is destroyed, regeneration is not possible
regeneration of a nerve occurs at ___ mm daily
1-2 mm daily
proximal nerve sections regenerate faster than those at increased distance from cell body
