P&O - Basic Biomechanics and General Orthotics

What are the primary functions/purposes of orthoses?

- protect RL

- correct alignment

- substitute for functional loss

- enhance function

- stabilize or immobilize limb segment or trunk

What is the term for a motion control type that eliminates motion?

Hold

What is the term for a motion control that deters undesirable motion?

Stop

What is the gist of the three point principle?

A single force at the area of deformity is counteracted by two additional counter forces in the opposing direction in order to create an immobilization of the deformed segment.

When evaluating a patient and determining whether or not to prescribe an orthotic for them, which goals do you make first? Functional or Orthotic Goals?

Develop functional goals first to determine whether or not an orthotic could be used to facilitate the patient's progress toward those goals (via orthotic goals)

How often does a patient wear their orthotic on day 1-2?

30-60min/day while checking for skin redness, breakdown, irritation, or blistering

How often does a patient wear an orthotic on days 3-4?

2-3 hrs/day while gradually increasing their skin tolerance

What should you NOT do when taking general care of an orthosis?

- soak in water

- dry with blow dryer

- place near heater

What footwear should you avoid wearing with an orthotic?

- high heels

- sandals

- low trim line loafers

You should __________ the insert in sneakers prior to placing your orthotic inside the shoe.

remove

What are some of the general considerations to remember with general orthotics?

- accommodate those bony prominences

- watch for edema

- cosmesis

- comfort

- function

- patient compliance

- cost/reimbursement
