Flashcards in Motor Exam Deck (30):
1

Muscle strength quick screen

Resist abduction, adduction, flexion and extension at the shoulder, elbow, fingers, hip and ankle
Resist flexion and extension at elbow and knee

2

Pronator Drift

Patient flexes both shoulders to 90 degrees, extends elbows and fully supinates both forearms and closes eyes.
Inability to maintain this position for 30 seconds, with gradual pronation and downward drift of one arm = UMN lesion

3

What does more severe atrophy indicate?

LMN lesion

4

What does less severe atrophy indicate?

UMN lesion or disuse

5

Rigidity:

Excessive resistance that not does not vary with the speed of the stretch

6

PROM:

Passively flex and extend patient’s elbow, wrist, knee, ankle and neck

7

Modified Ashworth Scale 0:

no increase in muscle tone

8

Modified Ashworth Scale 1:

slight increase in muscle tone, manifested by a catch or by minimal resistance as the end of ROM when the affected part(s) is moved in flexion or extension

9

Modified Ashworth Scale 1+

slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of ROM

10

Modified Ashworth Scale 2

more marked increase in muscle tone through most or ROM, but affected parts easily moved

11

Modified Ashworth Scale 3

considerable increase in muscle tone, passive movement difficult

12

Modified Ashworth Scale 4

affected parts rigid in flexion or extension

13

Babinski sign present:

Babinski’s sign is present if the great toe extends, other toes may spread apart

14

Location of touch:

DCML

15

Tactile thresholds:

dermatone, peripheral nerve

16

Two point discrimination:

DCML

17

Bilateral Simultaneous Touch

a lesion in the parietal lobe contralateral to the side of the body where sensory extinction occurs.

18

Graphesthesia:

this indicates a lesion in the contralateral parietal cortex or adjacent white matter.

19

Joint Movement and Joint position

Errors indicate dysfunction in the peripheral nerves, spinal cord, brainstem, or cerebrum.

20

Vibration:

large, Aβ peripheral nerve fibers and the dorsal column/medial lemniscus neurons.

21

Stereognosis:

lesion in the contralateral parietal cortex or adjacent white matter

22

Sharp prickling pain

lateral pain system

23

Romberg test pass/fail:

Moving arms or feet
Opening eyes
Beginning to fall or requiring assistance

24

Sensory ataxia romberg:

the person is able to maintain balance with EO for 30s but balance is impaired with EC

25

Sharpened Romberg:

Same as Romberg, but with one foot in front of the other foot

26

Phasic Stretch Reflex 0:

absent despite reinforcement

27

Phasic Stretch Reflex 1+:

slight reflex, present but depressed, low normal

28

Phasic Stretch Reflex 2+:

normal typical reflex

29

Phasic Stretch Reflex 3+

brisk reflex, possibly but not necessarily abnormal

30

Phasic Stretch Reflex 4+

very brisk, abnormal, clonus
