What is an advantage of THKAFO?

• A. Upright positioning for high level lesion
• B. Increased running speed
• C. Enhanced detailed hand function
• D. No need for upright posture

Answer: (A)

The main benefit of a THKAFO is enabling upright positioning for someone with a high-level lesion. This device combines a trunk-support with hip, knee, ankle, and foot orthoses, so it provides rigid trunk stability and leg alignment that many high-level spinal or myelomeningocele patients lack. That stability makes standing and weight-bearing possible, which is not achievable with simpler braces.

Standing offers several advantages: it helps improve bone density through weight-bearing, promotes better circulation and venous return, and can reduce the risk of secondary issues like contractures and scoliosis progression. It also supports functional goals such as participation, balance training, and potential gait rehab.

The other options don’t fit because running speed isn’t the primary purpose of a THKAFO, nor does it specifically enhance fine hand function, and the device is chosen to restore or enable upright posture rather than remove it.
