what is an orthosis
|
external appliance worn to restrict or assist motion, or transfer load from one area to another
|
|
what is a splint
|
an orthosis for temporary use
|
|
for orthotic prescription, how are outcomes achieved
|
through selected application of forces
|
|
what are the two main purposes for orthotics
|
- to control motion
- to assist motion |
|
what are the outcomes for orthotic prescription
|
- rest/protection of a joint
- immobilization - joint protection - control of instablility - assisting movement - providing feedback - correction |
|
what are the principles of force transmission
|
- bending moment and transverse shear forces
- 3 or 4 point loading system |
|
what is the point of the 3 or 4 point loading system
|
to get the correction you need to apply equal and opposite forces
|
|
how do you support a compressive load
|
through soft tissue or fluid compression
|
|
tension via distraction increases _________, which is then further stabilized by ____ and _______
|
- lateral stability
- which is then further stabilized by application of transverse or horizontal forces |
|
what determines the materials used for orthotics
|
- depends on the goal of the orthotic
- more rigid = more control you have |
|
what happens to motor function if you immobilize a joint
|
reduce the opportunity for return
|
|
lack of proprioception has what effect on a joint
|
makes a joint unstable
|
|
why is UE function important
|
1) for Donning/ doffing orthoses
2) may need strength for using assistive devices |
|
what are the important elements to the psychological status of the patient during pre-prescription assessment
|
- will the pt. wear the orthotic?
- can they follow through with instructions for application, care, safety, etc? |
|
How are prosthetics usually covered financially
|
- Usually covered under DME rules
- Letter of justification often needed |
|
How long should it take for skin irritation to go away if the prosthetic is appropriate
|
1 hour
|
|
what are the components of PT orthotic training
|
1) donning/doffing the orthotic
2) standing balance 3) walking/ safety 4) other mobility skills- ramp, steps, uneven surfaces |
