An elderly patient has diabetic neuropathy. Upon examination he shows marked mediolateral instability of the left ankle while walking. The MOST appropriate orthotics aid would be:

• A. a double-upright ankle foot orthosis
• B. hip to toe shoes
• C. a prefabricated plastic, solid ankle-foot orthosis
• D. a spiral ankle foot orthosis

Answer: (A)

When there is mediolateral instability at the ankle, the goal is to limit side-to-side movement so the ankle stays aligned during stance and gait. A double-upright ankle-foot orthosis does exactly this by providing rigid braces on both sides of the ankle, which controls inversion and eversion. This coronal-plane stabilization is especially important in diabetic neuropathy, where sensation is diminished and the risk of missteps or ankle injuries is higher. By bracing the ankle medially and laterally, the device improves foot alignment, enhances safety, and supports a more stable gait. In contrast, other options offer less targeted coronal stability or rely on structures that don’t address ankle side-to-side control as effectively (spiral AFO is more dynamic and less rigid; a solid AFO is less specific in its stabilization; hip-to-toe shoes don’t stabilize the ankle).
