The Healthspan Mobility Index combines six mobility-related tests into a single calculated mobility age score, your HSMI.
It answers the question: “How does my calculated Mobility Age compare to my actual age and the mobility of many thousands of others of my age and gender?”

Trajectory (Expected Decline)
Scenario forecast. Projects VO₂, TUG, Sit & Reach, Grip Strength, Postural Sway, and Mid‑Thigh Pull forward using age-related decline slopes derived from embedded norms.
Scales all six decline rates derived from norms. Editing the VO₂/TUG/Sit & Reach boxes below overrides the multiplier for those tests.
