  1. what are 4 types of orthoses?



    shoe inserts
  2. what are 7 goals for orthoses?
    • 2. immobilization
    • 3. joint protection
    • 4. control
    • 5. assisting movement
    • 6. providing feedback
    • 7. correction
  3. if goal is immobilization to protect joint must do what?
    substitute for the lack of intrisic joint stability normally achieved by bones, muscles, ligaments
  4. what are the 2 things an orthotic prescription must take into account?
    control and assist movement
  5. orthotics and application of forces
    • orthotics have increased pressure at points of force application
    • greater concern for patients with sensory or cognitive deficits
  6. to abvoid pain and skin breakdown forces should be sustained over as _______large/small a body surface area as possible because it ______incr/decr the force

  7. what is the 3 point loading system in orthotics?
    sum of forces and sum of bending moments = zero
  8. T/F effectiveness of 3 point loading system is strongly influenced by the location of forces relative to the joint axis
  9. the _____farther/shorter the end forces are from the joint the ______greater/lesser their moment arms

    the ______smaller/larger the magnitudes required to produce a given torque at the joint


  10. what 4 things make up an ideal orthotic
    1. performs desired function

    2. improves QOL

    3. comfortable during use

    4. meets patients needs and goals
  11. T/F orthoses should control only those movements that are considered abnormal while permitting free motion of unimpaired segments
  12. foot orthoses enhance function by relieving pain by the following 4 ways:
    • 1. transfer WB to pressure tolerant areas
    • 2. minimize contact with pressure sensitive areas in shoe
    • 3. correct alignment of flexible segment
    • 4. accomodate for a fixed deformity
  13. What is a SMO used for?
    seen in peds patients

    address sagittal plane problems and facilitate foot clearance in swing
  14. solid AFO is used for?
    in patients who need total immobilization of ankle-foot complex to be stable

    helps with PF, inversion, eversion, DF control--faciliated knee extension in stance
  15. solid AFO's control for...
    • foot drop in swing
    • hyperextension of knee if in slight DF
    • hyperflexion of knee if in slight PF
  16. PLS dorsi assist AFO used for?
    during loading response PLS substitutes for eccentric contraction of pretibials providing controlled lowering of foot

    once limb is unweighted for swing PLS holds ankle at 90d for clearance and position
  17. double upright dorsi assist afo used for?
    assists DF in swing and smooth initial contact to loading response

    bad things: heavier, less cosmetic, inability to change shoes
  18. articulating ankle AFO used for?
    used in early stages of CVA
  19. 5 other types of orthoses?
    • knee
    • KAFO
    • spinal
    • UE splinting
    • casting
  20. orthosis care
    plastic cleaned with mild soap not antibacterial

    rinse with cold water

    air dry

    check skin

    keep out of extreme temperatures
