Exam 2 week 8 ppt 7 Somatosensory Clinical Correlations

Question 1

Define Neuropathy:

Answer 1

•disease of the peripheral nerves

Question 2

three types of neuropathy

Answer 2

1. Mononeuropathy
2. Radiculopathy
3. Polyneuropathy

Question 3

mononeuropathy

Answer 3

§Affecting one nerve such as carpal tunnel syndrome, damage to radial nerve with humeral fracture or common fibular nerve with fibular head fracture

Question 4

radiculopathy

Answer 4

§Affecting nerve roots with spinal nerve distribution

Question 5

polyneuropathy

Answer 5

§Affecting many nerves such as diabetes

Question 6

what is one of the most common causes of of polyneuropathy

Answer 6

Diabetes mellitus

Question 7

describe polyneuropathy from diabetes Mellitus:

Answer 7

–Characterized by distal, bilateral sensory losses
–Muscle wasting and weakness
–Progresses from distal to proximal – often called stocking-glove pattern

Question 8

Brown Sequard Syndrome

Answer 8

•Lesion of one-half of the spinal cord and all fibers entering the cord via the dorsal root producing:

• –Ipsilateral zone of somatosensory anesthesia at the damaged dermatomes
• –Ipsilateral loss of DC-ML modalities below the lesion
• –Contralateral loss of STT modalities below the lesion
• –Ipsilateral spastic paralysis

Question 9

Syringomyelia

Answer 9

• •Disease process in the center of the spinal cord, usually over a few cervical segments
• •Disrupts pain and temperature fibers of the STT in the ventral white commissure
• •Characterized by bilateral loss or pain and temperature sensibility, usually in the hands and arms

Syringomyelia is a Disease process in the center of the spinal cord, usually over a few cervical segments

Disrupts pain and temperature fibers of the STT in the ventral white commissure and so is Characterized by bilateral loss or pain and temperature sensibility, usually in the hands and arms

Question 10

Subacute Combined Degeneration

Answer 10

• •Disorder that typically first involves the fibers of the dorsal columns
• •Early symptoms include symmetrical parathesias of fingers and toes and loss of proprioception
• •Person may demonstrate unsteady, ataxic gait

Subacute Combined Degeneration is a Disorder that typically first involves the fibers of the dorsal columns

Early symptoms include symmetrical parathesias of fingers and toes and loss of proprioception. As the disease progresses the patient may demonstrate unsteady, ataxic gait

Question 11

Examination of the Somatosesory Systems: Three things about them

Answer 11

1. •Relies on capacity of patient to cooperate and report feelings and sensations
2. •Clinical tests are only remotely related to real-life sensory experiences
3. •Tests for each spinal cord tract
   
   • –Anterolateral-spinothalamic tract
   • –Dorsal column–medial lemniscus

Evaluation of the somatosensory system Relies on capacity of patient to cooperate and report feelings and sensations. Clinical tests are only remotely related to real-life sensory experiences due to the testing of isolated sensory functions. There are Tests for each spinal cord tract with separate tests for the Anterolateral-spinothalamic tract and Dorsal column–medial lemniscus

Question 12

do we need to know the Tests to Assess Somatosensory System Integrity (Tabel 9-4)?

Answer 12

No not in this class right now according to Dr. Lake
