Walking is the result of the whole system
Propulsion, balance, sensory input and joint motion all contribute to the final speed. A single value does not identify which component changed.
Why steps may become shorter
Shorter steps can accompany a more cautious strategy, lower propulsion or a lower chosen speed. These adaptations may support stability but do not explain the cause by themselves.
When to look further
A sudden change, new weakness, repeated falls, unusual shortness of breath, severe pain or neurological symptoms warrants professional assessment rather than self-measurement alone.
