The association of a leg positioned in plantarflexion with a short leg is based on biomechanical principles and how the body compensates for discrepancies in leg length. When a leg is short, the body often adapts by positioning the foot in plantarflexion. This position can help the shorter leg to make contact with the ground at the same time as the longer leg, aiding in maintaining balance and a level gait.

Plantarflexion refers to the downward movement of the foot where the toes point away from the leg, such as when standing on tiptoes. This adjustment provides a mechanical advantage, allowing the shorter leg to function more effectively during walking or running.

On the other hand, dorsiflexion, which is the lifting of the foot upwards, is generally associated with bringing the toes closer to the shin but does not inherently compensate for leg length discrepancies in the same way as plantarflexion. Neutral positioning refers to a standard anatomical position where the leg is aligned without compensation, and adduction pertains to moving the leg toward the body's midline, which does not specifically address leg length issues.
