A simple parameter with many determinants
Step length varies with body size, walking speed, terrain and instruction. A shorter step is therefore not automatically abnormal.
Why the body may shorten the step
A shorter step can reduce some balance demands and may accompany lower push-off power or a more cautious gait strategy.
Follow the trajectory
Cadence, step length and gait speed together give a more meaningful picture than any one value alone.
