The flashcards below were created by user hgienau on FreezingBlue Flashcards. What would you like to do?


  1. Sensory Integrity
    • Is the ability to organize and use sensory information.
    • Normal sensation: the ability to organize and intergrate movement and touch sensation feedback into normal functional and safe activities
  2. Types of Sensory Integrity
    • Peripheral: Sensitivity to touch
    • Cortical: two point discimination, Sharp/dull discrimination
    • Proprioception: Includes position sense and the awareness of the joints at rest
    • Kinesthesia: awareness of movement
  3. Diagnostic Groups
    Sensroy impairment can impose significant functional limitations for the Pt.
  4. Age Related Changes in Sensation
    • Decreases in many senstaions occure
    • Medications - can further influence the affects of aging on sensation
  5. Purpose of Testing Sensation
    Determine the level of sensory feedback affecting Pt movement
  6. Superficial Sensation Tests
    • Exteroceptors
    • Revieve superfical sensation from the external environment throught the skin and subcutaneous tissue
    • Pain
    • Temp
    • Light Touch
    • Pressure
  7. Deep Sensation Tests
    • Proprioceptors
    • Reveive stimuli from muscles, tendons, and ligaments, joints, and facia
    • Responsible for position sense and awaremess of joint at rest
    • Movement awareness (kinesthesia)
    • vibration
  8. Combines cortical Sensations
    • Require infromation from both exteroceptors and propriceptors as well as intact function of cortical sensory association areas
    • Stereognosis
    • Two Point Discrimination
    • Tactile localization
  9. Pathways
    • Anterolateral spinothalamic
    • Dorsal Column Medial lemniscal System
  10. Anterolateral Spinothalamic Tract
    • initiates self protection reactions and responds to stimuli that are potentially harmfull in nature
    • Slow conduction fibers of small diameter
  11. Dorsal Column
    Medial Lemniscal systemInvolved in responses to more discriminative sensations
  12. Light Touch Test
    Use cotton ball
  13. Pressure Test
    use finger and have them tell you when they feel you touching them.
  14. Proprioception
    • hold on sides of finger
    • 3 stops
    • Begining middle and end
  15. Kinesthesia
    • Pt responds Up or Down
    • Two stops
  16. Vibration
    • Show test of sternum
    • show on good side first
    • tell me when u feel it and when it stops
    • LE: distal phylanx of great toe, medial malleolus, knee, ASIS, spinous process of L-spine
    • UE : Distal phalanx of index finger, ulnar syloid process, olecranon process, acromion process, spinous process of C-spine
  17. Stereognosis
    give pt 5 items
  18. Tactile Localization
    Top bottom inside outside
  19. Two Point Discrimination
    use aesthesiometer
  20. Simultaneous Stimulation
    Start distal and proximal and work your way in
  21. Deep Tendon Reflex Testing
    • Biceps - C5 hand in supine
    • Brachioradialis C6 hand in neutral
    • Triceps C7
    • Quadriceps L2-4
    • Achilies S1-2
  22. Deep Tendon Reflex Testing Grading
    • 0: no response
    • 1+ minimal response - slight muscle contraction witout joint movement
    • 2 + normal repsonse
    • 3+ brisk response
    • 4+ hyeractive reflex
