Gait Speed
Compare how three line-crossing rules change a gait-speed measurement.
What the interactive shows
Compare body, leading-toe and grounded-heel timing rules. Adjust pace, height, course distance and footfall alignment, and inspect the different timing windows.

Evidence & interpretation
An educational model of protocol mechanics. The source study involved 31 healthy adults and two assessors; modelled motion is distinct from observed study intervals.
How the model works
Dynamic-start timing over a marked span. The interactive labels manuscript findings, calibrated parameters and modelled outputs separately. Its default 6 m course corresponds to the study’s 2–8 m timed span.
Publication status
Brosnan et al. Improving gait speed assessment accuracy: Waiting for the whole foot to cross the line increases error during routine assessment. The interactive identifies this as a supplied peer-review manuscript; no public manuscript URL is shown.
