Which of the following is NOT a common type of orthotic used for children with CP?

• A. Solid AFO
• B. Hinged AFO
• C. Carbon-Fiber AFO
• D. Hydrostatic AFO

Answer: (D)

Ankle-foot orthoses for children with cerebral palsy are chosen to control ankle movement and improve gait, with several common designs. A solid AFO provides rigid ankle stabilization, helping to prevent unwanted plantarflexion and maintain knee alignment during stance. A hinged AFO adds a mechanical ankle joint that permits controlled dorsiflexion and plantarflexion, which can improve knee mechanics and allow more natural progression in stance. A carbon-fiber AFO is lightweight and stores energy during early stance, returning it during swing to aid push-off and make walking more efficient. A hydrostatic AFO, which would rely on fluid-filled compartments to support the ankle, is not a standard or widely used design in pediatric CP care because there is limited evidence of benefit, it adds weight and complexity, and maintenance can be challenging. Therefore, hydrostatic AFO is not a common type for children with CP.
