1. Types
   1. Serial-Static Orthotic Provisioin
      1. Purpose: immobilize a joint
      2. Positions a joint near its elastic limits to overcome a loss in passive ROM
      3. Recommended for contractures w/ hard end feel
      4. Recommended across the continuum of healing
   2. Dynamic Orthotic Provision
      1. Purpose: to apply sufficient tension that does not overpower the joint and allows the client to overcome the resistance and move in the opposite direction
      2. Recommended when collagen is forming
   3. Static-Progressive Orthotic Provision
      1. Has inelastic components to apply torque to a joint in order to statically position the joint as close as possible to end range
      2. Recommended during the proliferative and chronic stages of tissue healing when collagen is forming
2. Biomechanical Principles
   1. Anatomical Considerations
   2. Mechanical Advantage
   3. Torque
   4. Force
3. Common Features
   1. Outrigger
      1. A projection from the orthotic base
      2. High
         1. Results in less deviation; bulky
      3. Low
         1. Requires adjustments more frequently but aeshetically pleasing
4. Goals
   1. Correction of deformities
   2. Substitute for loss of muscle function
   3. Provide Controlled Motion
   4. Aid in wound healing
