For a custom articulating ankle-foot orthosis with anterior trim lines, which statement is true?

• A. It provides total contact and stability
• B. It uses posterior trim lines
• C. It blocks dorsiflexion
• D. It is used only for cosmetic reasons

Answer: (A)

Trim line placement in an articulating AFO affects how the device contacts the leg and how stable it feels. An anterior trim line means the shell wraps along the front of the leg, creating a broad, continuous surface that hugs the shank. This increased contact area helps distribute pressures and resist unwanted movement, contributing to overall stability around the ankle and better total contact with the leg. The ankle joint in an articulating AFO still allows controlled dorsiflexion and plantarflexion, so dorsiflexion isn’t blocked by having an anterior trim line. And such an orthosis isn’t used only for cosmetic reasons; its purpose is to provide functional support, improve alignment, and aid gait.
