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
