Sensory And Motor Function

Question 1

**

Superficial Sensations
(4)

Answer 1

Pain: Assess sharp/dull discrimination

Temperature Awareness: Assess the ability to distinguish between hot and cold stimuli

Touch Awareness: Assesses perception of tactile touch input

Pressure Perception: Assesses perception of pressure by the deep receptors

pg. 256-257

Question 2

Deep Sensations
(3)

Answer 2

Proprioceptive Awareness: Determines joint position sense and the awareness of joints at rest

Kinesthesia Awareness: Determines awareness of movement

Vibration Perception: Assesses the ability to perceive vibratory sensation

pg. 256-257

Question 3

Cortical Sensation
(7)

Answer 3

Stereognosis Perception: Assess tactile object recognition

Tactile Localization: Assesses the ability to localize touch sensation
- Measurement reflects the relative sensitivity of a specific area of the body

Two-point discrimination: Assesses the ability to perceive 2 separate points on the skin simultaneously and measure the minimal detectable distance between the points

Double Simultaneous Stimulation: Assesses the ability to perceive simultaneous touch stimulus on:
1- Identical locations on the opposite side of the body
2- Proximally and distally on a single extremity
3- Proximally and distally on one side of the body (different extremities)

Graphesthesia: Assess the ability to identify either numbers, letters, designs that have been traced on the skin

Texture Recognition: Assess the ability to differentiate among various textures

Barognosis: Assesses recognition of weight

2. Multiple Sclerosis
3. Brain Injury (acquired or traumatic)
4. Spinal Cord Injury
5. Stroke
6. Cerebral Palsy
7. Tumor in Brain &/or SC

Question 5

LMN Lesions (Conditions)

7 Conditions

Answer 5

1. Amyotropic Lateral Sclerosis (ACL)
2. Bell’s Palsy
3. Gullian-Barre Syndrome
4. Cauda Equina Syndrome
5. Peripheral Nerve Injuries
6. Poiliomyelitis
7. Post-polio Syndrome

Question 6

DECORTICATE RIGIDTY

Level of lesion, response, U/E & L/E

Answer 6

• Corticospinal tract lesion at level of DIENCEPHALON (hypothalamus & thalamus)
• Abnormal FLEXOR response
• U/E
  1. shoulder adduction
  2. elbow flexion
  3. wrist flexion
  4. finger flexion
• L/E
  1. leg extension & internal rotation
  2. ankle plantar flexion

The difference from DECEREBRATE rigidity is IR

• U/E
  1. shoulder adduction
  2. elbow extension
  3. forearm pronation
  4. wrist flexion
  5. finger flexion
• L/E
  1. Leg extension
  2. ankle plantar flexion
