COF Follow-up Care & Device Modification Assessment

Question 1

During a follow-up visit, you notice persistent redness over a patient's medial malleolus after 2 hours of AFO wear. What is the most appropriate first action?

Accepted Answer

Identify the specific pressure point and modify the orthosis to relieve it

Answer

Persistent redness indicates a localized pressure area that is within the fitter's scope to address. The orthotic fitter should identify the exact contact point and modify the device to redistribute pressure before the patient continues wearing it. Discontinuation or deferring without modification would be premature.

Question 2

A patient returns at 3 months with a prefabricated thermoplastic AFO. The shell shows visible stress marks (crazing). What does this finding most indicate?

Accepted Answer

Material fatigue indicating the device has lost structural integrity and requires replacement

Answer

Crazing (stress marks) in thermoplastic indicates material fatigue — the polymer chains have begun to fail, meaning the device can no longer reliably provide the intended support. The device should be replaced, not continued in use.

Question 3

What is the PRIMARY clinical purpose of a scheduled follow-up evaluation 4–6 weeks after orthotic device delivery?

Accepted Answer

To assess skin integrity, patient adherence to the wearing schedule, and functional outcomes

Answer

Early follow-up is designed to catch problems before they cause harm: checking for pressure areas (skin integrity), verifying the patient is wearing the device as prescribed (adherence), and evaluating whether functional goals are being met. This is a clinical visit, not an administrative one.

Question 4

A patient with a prescribed knee orthosis reports they 'only wear it when the pain gets bad.' How should the orthotic fitter respond?

Accepted Answer

Recognize this as non-adherence and address the underlying reason through education or device adjustment

Answer

Most orthotic prescriptions require a consistent wearing schedule — not symptom-driven use — to achieve therapeutic goals such as stability and deformity prevention. Non-adherence should be explored: Is the device uncomfortable? Does the patient misunderstand its purpose? The fitter should address modifiable barriers before escalating.

Question 5

During a follow-up visit, which finding most urgently requires device replacement rather than in-clinic adjustment?

Accepted Answer

Delamination of the inner foam liner creating asymmetric contact with the skin

Answer

Delamination of the liner creates uneven pressure distribution across the skin, which can cause pressure injuries and defeats the therapeutic intent of the device. This is a structural failure of the padding component requiring replacement, not minor adjustment.
