Movement strategy changes
Across healthy aging studies, differences have been reported in step length, double-support time, joint angles and joint power. These are population-level tendencies rather than inevitable individual changes.
The role of the ankle
Push-off from the ankle contributes to forward progression. Meta-analytic data describe lower plantar-flexion and ankle power generation in older adults, which can shift part of the mechanical work toward other joints.
Why this matters clinically
Two people may walk at a similar speed using different strategies. Looking at the mechanics can therefore add context to a simple functional outcome.
