National Physical Therapy Examination (NPTE) Practice Exam

What activity would best facilitate the goal of a posterior mobilization of the talus?

1. Performing heel raises while seated

2. Walking on tiptoes on level surfaces

3. Performing single limb stance activities

4. Ascending and descending stairs with a reciprocal pattern

The correct answer is: Ascending and descending stairs with a reciprocal pattern

The activity that best facilitates the goal of a posterior mobilization of the talus is ascending and descending stairs with a reciprocal pattern. This movement is effective because it involves dorsiflexion and plantarflexion of the ankle during the stair ascent and descent, which inherently promotes posterior glide of the talus. During stair climbing, when the foot is placed on the stair and the body weight is shifted forward, the talus moves posteriorly relative to the tibia, effectively engaging the posterior structures of the joint. This active movement supports the posterior mobilization technique, enhancing joint mobility and function. Additionally, the reciprocal pattern emphasizes weight-bearing through the joint while engaging the surrounding musculature, which can aid in facilitating proper arthrokinematics of the talus. While the other options might involve ankle movement, they do not facilitate the same level of posterior stabilization and mobilization needed at the talus. Performing heel raises while seated primarily engages the calf muscles without significant ankle joint mobilization. Walking on tiptoes primarily works on plantarflexion and does not effectively address the posterior glide. Performing single limb stance activities may improve balance and stability, but also lacks the dynamic movement that actively assists in posterior mobilization of the talus.
