Stride Length Asymmetry

Stride length asymmetry is a measure of the difference in stride length for each leg. Asymmetry measures are best used in conjunction with a baseline for each individual, as every person has inherent asymmetries. Note that turning will create a stride length asymmetry as the inner foot and outer foot must travel different distances (see Figure 3).
