Which mobilization technique best improves 1st MTP extension?

• A. Glide the distal phalanx in a superior direction
• B. Stabilize the metatarsal and glide the proximal phalanx superiorly
• C. Apply a manual distraction to the 1st ray
• D. Glide the proximal phalanx inferiorly

Answer: (B)

The mobilization technique that best improves 1st MTP extension is to stabilize the metatarsal and glide the proximal phalanx superiorly. This technique effectively addresses the mechanics of the 1st metatarsophalangeal joint (MTP), which plays a crucial role in the function of the big toe during activities such as walking and running.

By stabilizing the metatarsal, the clinician ensures that the base of the toe remains fixed, allowing for focused movement of the proximal phalanx. When the proximal phalanx is glided superiorly (toward the dorsum of the foot), it aids in facilitating the desired extension of the toe, which is essential for proper gait mechanics and push-off during locomotion. This superior glide is particularly important because toe extension often occurs when the foot is in a weight-bearing position, where the mechanics of the joint need to allow for effective propulsion.

The other techniques may not target the joint mechanics effectively for improving extension at the 1st MTP. For instance, gliding the distal phalanx does not adequately influence the motion at the joint itself, while applying a manual distraction may provide general mobility but does not specifically enhance extension.
