Sensation

Question 1

Sensory Integration

Answer 1

• The ability of the brain to organize interpret and use sensory information
• It provides an internal representation of the environment that informs and guides motor responses

Question 2

Motor learning and motor performance are dependent on what?

Answer 2

Sensation

Question 3

Feedback Control

Answer 3

• uses sensory information during movement to guide output

Question 4

Feedforward Control

Answer 4

• proactive strategy to plan movement

Question 5

Somatosensory

Answer 5

• Sensation received by skin and muscles senses that are not specialized

Question 6

Specific Sensory Patterns

Answer 6

Dematomal Distribution
Peripheral Nerve Distribution
- pts will show specific area of distribution

Question 7

Dematomal Distribution

Answer 7

• based on nerve roots

Question 8

Peripheral Nerve Distribution

Answer 8

• area of skin innervated by a single nerve

Question 9

Non- Specific Sensory Patterns

Answer 9

Varied and will be a non-specific or vague area
Exaples:
- PAD
- Diabetes
- MS
- SCI
- Stroke

Question 10

Superficial Sensation / Exteroceptors

Answer 10

Responsible for the perception of:

• Pain
• Temperature
• Light Touch
• Pressure

Question 11

Deep Sensation Proprioceptors

Answer 11

• Receive stimuli from muscle, tendons, ligaments, joints and fascia
• Responsible for:
• Position sense and joint awareness (proprioseption)
• Movement awareness (Kinesthesia)
  Vibration

Question 12

Combined Cortical Sensation (Sensory Classification)

Answer 12

Requires information from both superficial and deep receptors as well as sensory association areas

• Seteriogenosis
• 2 Point Discrimination
• Barognosis
• Graphesthesia
• Tactile Localization
• Recognition of texture
• Double Stimulation

Question 13

Receptors Type

Answer 13

• Mechanoreceptors
• Thermoreceptors
• Nociceptors (Pain)
• Chemoreceptors
• Photic receptors (light)

Question 14

Testing and Pt Prep

Answer 14

• What you’re going to do
• Trial run
• Occluding Pt’s vision
• Normally distal to proximal
• Test range of dermatomes and nerve patterns
• Bilaterally vs Unilaterally
• Time is of the essence
• Make it randome

Question 15

Superficial Testing

Answer 15

• Pain Perception (Sharp/Dull)
• Temperature (warm/cool)
• Light Touch (yes/no)
  Pressure Perception (touch)

Question 16

Deep Testing

Answer 16

• Kinesthia (describes the movement)
• Proprioception (Matches the position of other limb)
• Vibration (yes/no)

Question 17

Combined Testing

Answer 17

• Stereognosis (Identify object in hand)
• Touch Localization (states location)
• Two Point Discrimination (1 or 2)
• Graphesthesia (Name letter or number)
• Recognition or texture (identify texture)
