a static or dynamic externally applied device use to improve function.
Orthosis
What are outcomes of orthotics?
Prevent deformity Correct deformity WB support Assist or limit mvmt. Decrease pain Improve posture Immobilize Provide feedback Improve cosmoses
Indications for orthotics
impaired: posture muscle performance Jt mobility motor fx sensory integrity prophylactic
resists or directs force
brace
maintains or attains a position

different materials that orthotics come in
thermoplastic
metal
carbo fiber
Principles of design include
Pressure distribution (f/a)
Length of force arm
Ground reaction force
control degrees of freedom
3 pt. pressure system shows
2 supports on one side,
one on the other
how would you set up wc with 3 point pressure system to reverse decorticate posturing?
tilt the wheelchair.
corrects limb length discrepancies
foot lift
reduce achilles tendon stress
Heel lift
redistribute fat pad to improve shock absorbtion (plantar fasciitis)
heel cup
Reduces WB through metatarsals, Talocrural, and subtler joints
AFO patellar tendon WB
immobilize ankle jt, rocker bottom, able to adjust, doesn’t unload distal structures
