What is a contraindication for molded AFOs?

• A. Contraindication for patient with changing leg volume
• B. Lightweight, snug fit
• C. Do not use in presence of spasticity
• D. Provides dorsiflexion assistance

Answer: (A)

Molded AFOs rely on a precise, custom fit by heating and shaping the shell to the current contours of the leg and ankle. Because of that, they work best when the limb size remains stable. If leg volume is changing—through swelling or shrinkage—the mold can’t maintain proper contact or alignment. Increased swelling makes the shell press into tissues, causing pressure points, skin irritation, or circulatory issues. Decreased volume can make the brace loose, reducing ankle control and increasing friction or slippage. This instability in fit and function is why changing leg size is considered a contraindication for a molded, custom-fitted AFO. A lightweight snug fit is actually desirable, so that aspect isn’t a contraindication. Spasticity is not a blanket barrier to use, and dorsiflexion assistance is a functional feature of some molded AFOs, not a contraindication.
