Answer 8

Vibration

Question 9

Inability to recognize shape & form

Answer 9

Stereoanesthesia

Question 10

Inability to identify an object by palpation, even though the primary sense data are intact

Answer 10

Astereognosis

Question 11

A disturbance in which a one-sided lesion lying posterior to the post-central gyrus of the dominant parietal lobe results in an inability to recognize an object by touch in both hands

Answer 11

Tactile agnosia

Question 12

Symmetrical distal sensory loss
Sensory loss may affect one modality preferentially
Areflexia or hyporeflexia
Weakness, if present, symmetrical

Answer 12

Polyneuropathy

Question 13

Asymmetrical sensory & motor loss
Proximal & distal parts of limb differentially affected
Reflex loss limited to region of affected root(s)

Answer 13

Polyradiculopathy

Question 14

Implicates all sensory modalities
Proximal body parts affected
Ataxia

Answer 14

Ganglionopathy

Question 15

Prominent loss of position & vibration sense in feet
Romberg sign
Secondary (Charcot) joint deformities
Areflexia

Answer 15

Tabetic syndrome

Question 16

Loss of all sensory modalities below level of lesion

Answer 16

Complete transverse lesion of the SC/ complete spinal sensory syndrome

Question 17

Loss of pain sense opposite to the lesion & beginning several levels below it
Loss of vibration & joint position sense on the side of the lesion & below it

Answer 17

Hemicord/ Brown-Sequard

Question 18

Loss of pain & thermal sense with preservation of touch & position/vibration over restricted region of neck, cape, arms, & hands

Answer 18

Syringomyelia

Question 19

Same as tabetic syndrome but reflexes are preserved

Answer 19

Posterior column syndrome

Question 20

Answer 20

Anterior myelopathy/ Anterior spinal artery syndrome
