Hypesthesia
28
Increased sensitivity term
Hyperesthesia
29
Allodynia means
Mia perception of trivial tactile sensation as pain
30
Term for no pain term for no touch
Analgesia or hy palgesia | Anesthesia hyp esthesia
31
Leg touch vs arm touch
``` Gracilus ground Cutane ate (cut you arms) ```
32
Lateral spinothalamic tested by
Pin prick and temperature
33
How to asses deep pressure
Achilles' tendon pressure
34
What frequency assessed vibration
128 Hz
35
Abnormal 2 pt discrimination suggests
Diabetes Peripheral nerve problem Or somatosensory/ post central gurus
36
Agraphesthia means
Can't graph a number on hand | Deficit in counts lateral parietal lobe
37
A ster e og nosia means.
Can't distinguish between shapes
38
Inability to distinguish between two weights
A bar og no sis
39
Inability to distinguish between two shapes
A ste re og nosis
40
Hemineglect means
In attention sensation from one side
41
Hemineglect of left side means
Right parietal
42
Compression lesions affect what type neurons
The largest ones which affect touch
43
Mononeuropathy means
Single peripheral nerve
44
How can you tell it mononeurooathic
Small there is a lot of overlap
45
Term for stocking glove pattern
Polyneuropathy
46
Ddx for stocking globe
Dm Amyloidosis Tangier dx
47
What is tangier disease (tan jeer)
No hdl
48
Roots involved in reflexes
Ankle is s1 2 Knee is l3 L4 Bi c5 c6 Tri c7 to c8
49
If muscle weakness is radical at pain is involved it suggests
Both sensory and motor which means front and back of spine is involved. Dorsal and ventral root
50
Why is the back the most reliable way to test for the transverse level.
Because the breast and groin are sensitive
51
Describe redicular pain
Lancinating | Worse with movement
52
Differential for L5
Deep per o neal
53
Differential for L4
Superficial peroneal | Check reflexes
54
S1 nerve deficit ddx
Sural
55
Where is the spinal thalamic in medulla
Dorsal lateral medulla and pons
56
What land mark determines whether crossed signs occur
Spinal trigeminal nucleus
57
How do crossed signs an the spinal trigeminal relate
If the lesion is is in the spinothalamic tract, analgesia on the opposite side. No face. If lesion involves spinal trigeminal nuclei in dorsolateral, than you get crossed sensory deficit. - cn 9 to 12 impaired. If lesion is above spinal trigeminal nuclei than you get a deficit that is all on the contralateral side If lesion is above
58
Where does the spinothalamic and medial lemniscus run together
Upper brain stem. Pons
59
Spontaneous pain syndrome can occur from
Thalamus | Parietal white matter
60
