25
Resting tremor | - describe
- Parkinson's disease, basal ganglia | - best observed when there is no movement
26
Resting tremor examples
- pill rolling - cogwheel rigidity: jerky muscle flexion - flattened affect - shuffling gait - arrested gait - not present during sleep
27
Muscle tone testing | - overview
- pt contracts muscle against resistance - quickly release muscle and watch for jerking response (clonus, cogwheel) - check each UE and LE separately, compare - check for symmetry and appropriateness for development and age
28
Fine motor movement tests (2)
- precision finger tap | - toe tap
29
Strength grading
0: no movement or contraction 1: flicker but no movement 2: horizontal plane, voluntary movement but not enough to overcome gravity 3: movement overcomes gravity but not resistance 4: voluntary movement capable of overcoming resistance 5: normal strength
30
Individual muscle groups to test UE
1. arm abduction: deltoids/axillary nerve 2. Elbow flexors: biceps/ musculocutaneous nerve 3: Elbow extensors: triceps/radial nerve 4: wrist flexors: flexor carpi ulnaris and radialis/median nerve 5. Wrist extensors: extensor carpi/radial nerve
31
Additional UE strength tests
- grip strength (squeeze fingers) - abduction/adduction of fingers: ulnar nerve - touch thumb to 5th finger and don't let me pull through: median and ulnar
32
Individual muscle groups to test LE
1. Hip flexors: iliopsoas/LS plexus 2. Knee extensors: quadriceps/femoral nerve 3. Knee flexors: hamstrings/sciatic nerve 4. Ankle dorsiflexors: anterior tibialis/deep peroneal nerve 5. Ankle plantar flexors: gastrocnemius/tibial nerve
33
Additional LE strength tests
- move great toe up and down | - inversion/eversion of foot against resistance
34
5 things to test when testing sensation
1. light touch 2. pain (sharp and dull)/temperature 3. Proprioception 4. two point discrimination 5. vibration
35
How to test sensation
- test pain sharp pain and light touch first - if can't feel touch, then test proprioception and vibration - if can't feel pain, then test temperature
36
How to test sensation if in a rush
- test lowest dermatomes: fingers and big toe
37
How to test proprioception
- pt closes eyes - move finger (or other joint) up and down, stop - ask patient which direction it is pointed * hold joint on sides, not on top and bottom
38
What is the first sensation to go in DM
- vibration
39
What is light touch testing?
dorsal column
40
what is pain and temperature testing?
spinothalamic tract
41
What is proprioception testing?
dorsal column
42
What is two point discrimination testing
dorsal column
43
What is vibration testing
dorsal column
44
Cortical sensation | - 3 tests list
1. Graphesthesia 2. Stereognosis 3. Tactile extinction
45
Graphesthesia
ID letter/number drawn on palm
46
Stereognosis
ID objects based on touch
47
Tactile extinction
ID touch simultaneously on both sides of body | - if have a loss, will only be able to identify touch on one side
48
What do abnormalities of cortical sensation tests indicate?
- lesion in contralateral somatosensory cortex - seen in Alzheimers - get an MRI!
49
Reflexes | - how to grade
``` 0 absent 1+ trace 2+ normal 3+ brisk 4+ non-sustained clonus 5+ sustained clonus ```
50
what to look for when testing reflexes
- symmetry!!
51
What are signs of upper motoneuron issue
- hyperreflexia - fasciculations - disuse atrophy
52
What are signs of lower motoneuron issue
- hyporeflexia | - atrophy
53
What are the five places to test reflexes and associated nerve
1. Achilles (S1-S2) 2. Patellar (L3-L4) 3. Brachioradialis (C5-C6) 4. Biceps (C5-C6) 5. Triceps (C7-C8)
54
Additional reflex test
Plantar response/Babinksi - run back side of hammer up outside of foot and across pad of foot - NL: downward contraction of toes - Babinski (positive test): upward great toe with fanning of other (UMN issue)
55
5 ways to test cerebellar function
1. finger to nose to finger 2. heel to shin 3. rapid alternative movements 4. tap each finger with thumb 5. tap the floor
56
How to test gait and station
- Observation of stance, posture, leg swing - toe-walking gait - heel-walking gait - stand on one foot and hop up and down - tandem (heal to toe) gait - Romberg: stand on one leg with arms out and close eyes
57
What sensations used to stand in place? | - when remove vision, what is tested?
- vision, proprioception, vestibular sense | - exposes upper motoneuron lesions if drift to side or fall sideways
58
Meningitis | - triad presentation
fever HA neck stiffness
59
Meningitis | - two signs
1. Kernig's sign: unwilling to extend leg at knee d/t pain | 2. rudzinski's sign: passive flexion of head induces flexion of lower limbs (into fetal position?)
60
Cauda equina syndrome - what nerves - name of presentation - common sx
- Nerve roots below L1-L2 - saddle numbness S2-S5 - urinary dysfunction (atonic bladder and constipation) - decreased rectal tone
