The knee-to-wall test is an important measure of ankle dorsiflexion mobility and lower limb function. It assesses the ability of the ankle to move forward over the foot while keeping the heel in contact with the ground, which is essential for activities such as walking, running, squatting, stair climbing, and balance. Reduced performance may indicate limited ankle mobility, joint stiffness, calf muscle tightness, or reduced lower limb function.

Measuring knee-to-wall distance provides valuable insight into an individual’s current ankle mobility and helps identify those who may benefit from targeted mobility exercises, calf flexibility work, or progressive strengthening. It can also assist in identifying asymmetries between limbs and developing appropriate exercise recommendations to improve movement quality, lower limb function, and stability. Additionally, it serves as a baseline measure, allowing changes in ankle mobility to be tracked over time and helping to monitor improvements in response to structured exercise interventions.
