What type of joint mobilization would you use to increase dorsiflexion?

• A. Anterior to Posterior
• B. Posterior to Anterior
• C. Inferior to Superior
• D. Superior to Inferior

Answer: (A)

To increase dorsiflexion, you need a glide that allows the talus to move posteriorly within the ankle joint. The talocrural joint has a convex talus moving on a concave tibia, so promoting a posterior glide of the talus (which is described as moving the joint surface from anterior toward posterior) frees up the end range for dorsiflexion. Applying this posterior glide helps the tibia advance over the talus and lengthens the posterior structures that can limit dorsiflexion. Gliding in the opposite direction would not enhance dorsiflexion and could limit it instead.
