Flashcards in neuro exam Deck (35):
1

what are cafe au lait blotches a sign of

neurofibromatosis

2

why is it useful to shake hands with the patient

assess myotonia

3

which muscles should be palpated for muscle bulk

quadriceps and calves

4

what does a flexed upper limb and extended lower limb suggest

hemiplegia

5

what does a wrist drop suggest

radial nerve palsy

6

what is chorea

abrupt involuntary movements

7

what is a postural tremour

tremour when the limb is maintained in a position

8

what does a fasciculation with weakness suggest

LMN degeneration

9

what lesion does clonus suggest

UMN

10

how is power assesed

scale of 0-5

0- no muscle contraction
1-flicker of contraction
2- joint moves when gravity is eliminated
3- movement against gravity
4- movement against resistance but weak
5- normal power

11

what nerves are used in hip abduction

L4/5/S1

glut medius and minimus, sartorius, tensor fascia latae

12

what nerves does knee flexion use

L5/S1

13

shoulder abduction

C5

14

elbow flexion

(musculocutaneous nerve)

C5,6

15

elbow extension (triceps)

c6/7/8

16

wrist extension

c6,7,8

17

wrist flexion

c6,7,8

18

finger flexion

T1

19

how do you classify reflexes

0 absent
+ normal but reduced
++ normal
+++ increased, could be normal
++++ greatly increased

20

brachioradialis reflex

C6

21

triceps reflex

C7

22

biceps reflex

C5

23

knee jerk reflex

L3/4

24

ankle jerk reflex

S1

25

babinski reflex

L5, S1, S2

26

what is sensory ataxia

loss of coordination caused by loss of sensory input into the control of movement
(not cerebellar dysfunction)

27

how can you tell if an ataxia is sensory rather than cerebellar

movement is near normal when eyes are open but much worse when closed

28

what lesions could cause a sensory ataxia

sensory peripheral neuropathies

dorsal column dysfunction

29

what is a positive Romberg's test

swaying with eyes closed indicates proprioceptive or sensory defect

30

what are the signs of cerebellar disease

nystagmus
dysarthria
dysdiadokinesia
intention tremor
past pointing
cerebellar drift and rebound
hypotonia

31

what does the acronym DANISH stand for

Dysdiadokinesia
ataxia
nystagmus
intention tremor
slurred speech
hypotonia

32

light touch, vibration, proprioception

dorsal columns

33

pain and temp

spinothalamic

34

what is Kernig's sign

hip flexion
further knee extension is painful
indicates meningeal irritation

35

how do you test for nerve root irritation

straight leg raising

a test done during the physical examination to determine whether a patient with low back pain has an underlying herniated disk,

patient lies down and legs are lifted in the air
