Which of the following is NOT listed as a thoracic level orthosis option?

• A. THKAFO
• B. Parapodium with swivel
• C. HKAFO
• D. AFO

Answer: (D)

Thoracic level orthoses are designed to stabilize the trunk and proximal joints from the chest down through the hips and legs to support standing or mobility after high-level spinal issues. THKAFO provides stability from the thorax through the foot, including hips, knees, and ankles, offering comprehensive support for the upper segments. HKAFO does the same down to the ankles, emphasizing hip, knee, ankle, and foot stabilization. A parapodium with swivel is a standing device that supports the legs and trunk enough to stand and move with assistance, suitable for higher-level injuries. An ankle-foot orthosis, however, supports only the ankle and foot and does not provide trunk or hip stabilization, so it is not considered a thoracic level orthosis.
