B. Intro to Orthotics
Terminology & Processes
 |
Classification terminology (e.g.,
AFO, KAFO) |
|
Basic Biomechanical
Principles
 |
3-point force systems |
|
joints (DOFs, ROM,
spring-loading, ...) |
|
|
Materials
|
Metals (steel, aluminum,
titanium, ...) |
|
Thermoplastics (polyehylene,
polypropylene, polystyrene, vinyls, ...) |
|
Thermosets (epoxies,
polyester, acrylic, ... often "not alone") |
|
Composites (fiberglass,
graphite, ...) |
|
Woods, leather, rubbers,
adhesives, ... |
|
|
Fabrication Procedures
|
Classic steps -- measurements
& negative impression (mold), client leaves, fabricating/modifying
positive cast, fabrication, fitting on client (days later) |
|
"On the spot" --
Low-temperature thermoplastics; purchased orthoses |
|
CAD/CAM -- digitizing device,
interactive computer program (with 3D shape-manipulation, CAM milling
machines & production thermoforming (local or remote), interface |
