Q

What is a 5 for muscle strength

A

Active against full resistance without evident fatigue (normal muscle strength)
*ask the patient to move actively against your opposing resistance
*5 if the patient overcomes you opposing movement

22
Q

What does the motor, cerebellar, vestibular, and sensory system do

A

M: strength
C: rhyming movement and steady posture
V: Balance and coordinating eye, head, and body movements
S: position sense

23
Q

How to test for coordination

A
  1. Rapid alternating movements
  2. Point to point movements
  3. Gait
  4. Stance
  5. Pronator drift
24
Q

How to conducted rapid alternating movements

A
  1. Patient turns hand rapidly over and back on thigh
  2. Taps tip of fingers rapidly on distal thumb
  3. Taps ball of foot rapidly on your hand
25
Q

How to conduct point to point movements

A
  1. Patient touches nose then your index finger as you move it to different positions
  2. Patient move heel from opposite knee down the shin to the big toe
26
Q

How to asses gait?

A
  1. Walk across room
  2. Walk heel to toe
  3. Walks on toes then heels
  4. Hops in place on one leg, then the other
27
Q

How to test stance

A

Romberg test
1. Patient stands with feet together and eyes open
2. Then eyes closed for 30 to 60 seconds without support
3. Loss of balance when eyes are closed is a positive test

28
Q

How to conduct pronator drift

A
  1. Patient stands for 20-30 seconds with both arms straight forward, palms up, and eyes closed tap arms briskly downward
  2. Pronation and downward drift of the arm is a positive test
29
Q

What is the scale for grading reflexes?

A

0: no response
1: somewhat diminished
2: average
3: brisker than average
4: very brisk hyperactive, with clonus (rhythmic oscillation between flexion and extension)

30
Q

What does reinforcement mean when assessing contractions?

A

Used when reflexes are symmetrically dismissed or absent
*You will have the patient hold their hand together and pull apart when testing the reflex

31
Q

What are the cutaneous stimulation reflexes?

A
  1. Abdominal reflexes: upper T8-10; lower T10-T12
  2. Plantar response: L5-S1
  3. Anal reflex: S2-S4
32
Q

What should you NOT do to a comatose patient?

A

Dilate their pupils or flex the neck

33
Q

What do the eyes of a comatose patient tell us?

A
  1. Eyes should be straight ahead
    *if the eye preference a side then the eyes look toward the side of the lesion
  2. Doll eyes
    *eyes should move towards the opposite side of the head turning
    *midbrain or pons lesion likely is unable to move towards one side
34
Q

How to conduct oculovestibular reflex

A
  1. Put ice water into ear canal
    *eyes should drift toward the irrigated ear if brain stem is intact
35
Q

If a patient presents with a headache what are some things to keep in mind?

A
  1. May need evaluation for life-threatening secondary causes such as meningitis, subarachnoid hemorrhage or mass lesion
36
Q

What are primary headaches?

A
  1. Migraine
  2. Tension
  3. Cluster
  4. Trigeminal autonomic cephalagias
  5. Chronic daily headaches
37
Q

What are secondary headaches?

A
  1. They arise from underlying structural, systemic or infectious causes
    EX: subarachnoid hemorrhage and meningitis
38
Q

What do subarachnoid hemorrhage typically presents as?

A
  1. “The worst headache of my life”
39
Q

What can classify a migraine headache?

A

POUND
P = pulsatile or throbbing
O = one-day duration or lasts 4 to 72 hours if untreated
U = unilateral
N = Nausea or vomiting
D = disabling

40
Q

If a headache is severe and has a sudden onset what may need to be considered

A
  1. Subarachnoid hemorrhage
  2. Meningitis
41
Q

What does vertigo represent?

A
  1. Vestibular disease usually from peripheral causes in the nerve ear such as benign positional vertigo
42
Q

What does progressive but rapid development of lower extremity weakness suggests?

A

Guillain-Barré syndrome

43
Q

How to identify proximal weakness?

A
  1. Ask them to comb hair or climb stairs
44
Q

What are proximal limb weakness associated with?

A
  1. PM/DrM
  2. Alcohol
  3. Drugs
45
Q

How to identify distal weakness?

A
  1. Ask about hand strength when opening a jar or using scissors
46
Q

What does bilateral distal weakness indicate?

A
  1. Polyneuropathy (diabetes)
47
Q

What is epilepsy defined as?

A
  1. Two or more seizures that are not provoked by other illnesses or circumstances
48
Q

Does epilepsy always involve a loss of consciousness?

A

No

49
Q

What is an essential tremor?

A
  1. A high-frequency bilateral upper extremity tremor that occur with both limb movement and sustained posture
50
Q

When do essential tremors go away?

A
  1. When the limb is relaxed
51
Q

What is restless legs syndrome characterized as?

A
  1. As an unpleasant sensation in the legs, especially at night that gets worse with rest and improves with movement of the symptomatic limb
