About
Foot Plantar Flexion Excursion indicates how much the foot can point downward away from the shin. This motion is critical for generating forward propulsion during walking and running, as the ankle plantarflexors provide the final push that drives the body forward. Plantar flexion also helps stabilize the ankle during standing and supports controlled lowering of the body during gait.
When plantar flexion excursion is limited, the foot and ankle may not produce enough propulsive force, leading to inefficient gait patterns and increased demand on proximal joints. Excessive excursion, on the other hand, may reduce stability and alter timing during push-off. Understanding plantar flexion availability helps clinicians evaluate propulsion mechanics, stability, and overall ankle function.
Effect of Deviation
Reduced plantar flexion may decrease push-off power and lead to compensatory patterns in the knee and hip, while excessive excursion may increase instability and loading variability during gait.
