Which statement best describes a contraindication for a plastic AFO with articulating ankle joint?

• A. Is Heavier Than Metal AFO
• B. Provides Total Contact and Should Not Be Used on Patients With Fluctuating Edema or Significant Sensory Deficits
• C. Has No Contraindications
• D. Should Be Used for All Edema Conditions

Answer: (B)

A key idea is that an articulated plastic AFO relies on a stable fit to protect the skin while allowing controlled ankle motion. It provides total contact to distribute pressure, but that becomes a problem when tissue conditions aren’t stable or when sensation is impaired. Fluctuating edema changes how the orthosis fits—from tight to loose—creating pressure points or gaps that can lead to skin breakdown or ulcers. Significant sensory deficits mean the patient may not feel excess pressure, heat, or irritation, delaying response and increasing risk of injury. Because these factors undermine safe and effective use, this combination describes a true contraindication for this type of device.
