Which combination of ankle-foot orthosis features is used to correct excessive supination, such as valgus post, lateral wedge, and AFO with lateral flange?

• A. AFO + DF stop
• B. Varus posts with medial flange
• C. Valgus post, lateral wedge, AFO + lateral flange
• D. SMO, UCBL

Answer: (C)

When addressing excessive supination, the aim is to promote eversion of the foot and maintain that corrected alignment during walking. A valgus post places a medial wedge under the hindfoot, tilting the heel into valgus (eversion) and reducing inversion. A lateral wedge adds eversion to the forefoot, helping realign the entire foot in a more valgus position. An ankle–foot orthosis with a lateral flange provides lateral stability, resisting any tendency of the foot to invert and thereby helping the correction hold through the stance phase. Using these elements together tackles alignment at multiple points of the foot and supports the corrected position during gait. Other options don’t combine these specific components designed to counter excessive supination: a dorsiflexion stop mainly limits ankle motion, varus posts with a medial flange would promote or sustain inversion, and SMO or UCBL orthoses are different designs that don’t specifically pair a valgus post, lateral wedge, and lateral flange for this correction.
