Spinal Cord |
|
Definition
| Loss of sensation depends on the extent and area of damage. Complete transection will result in loss of motor and sensory to all areas below damaged segment. |

Definition
Bilateral Loss (glove and stocking);
Vibration and Temp lost first
Progresses to loss of protective sensations |

Term
| Stocking and Glove Sensation Loss |
|
Definition
A pattern of peripheral nerve disease characterized by a relatively sharply demarcated loss of pain, touch, temperature, position and vibration sensation, accompanied by weakness, muscular atrophy, and loss of tendon reflexes–eg, the 'stocking' pattern of distal diabetic polyneuropathy, characterized by waxing and waning paresthesias that worsen at night

Cerebral Cortex |
|
Definition
Sensory loss on contralateral side
-Includes ability to localize the stimulation site (atopognesia)
-Parietal Lobe - Less discriminative sensation (sterognosis, graphesthesia, sensory attention) |

Sensory Lab Tests
Sharp/Dull |
|
Definition
*Explain the test
*Get a baseline on unaffected area (face etc.)
*Pt.'s eyes should be closes
*Work distal to proximal
*Compare symmetrical areas on opposite sides
*Randomly alternate between sharp and dull and no sensation.
*Ask for feedback about intensity as well as presence/absence of sensation
*If a deficit is found, map it carefully-compare with areas of innervation, dermatomes etc. |
