Push-off Asymmetry

A measure of the difference in Push-off between feet, as defined by:

(R-L) / max(R,L)

High Push-off Asymmetry (>15%) occurs when one side leaves the ground at a faster rate than the other. This can mean either poorer propulsive ability on one side, or a protective strategy to pull the leg through instead of pushing off the ground. When combined with larger GCT asymmetry on the same side, high Push-off Asymmetry can indicate that the opposite limb is fatigued, weak, or experiencing pain. When combined with larger GCT asymmetry on the opposite side, high Push-off Asymmetry can indicate weaker ankle musculature.

Asymmetry measures are best used in conjunction with a baseline for each individual, as every person has inherent asymmetries.
