Claim by claim

The source study was found, but the study's evidence could not be profiled, so these claims couldn't be checked.

Claim 1 of 6Not checkedProfessor Li Li formally proposes "Movement Span" as a new and independent dimension of aging, reshaping how aging is defined, measured, and addressed.View evidenceHide evidence

As stated"groundbreaking" new and independent dimension

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 2 of 6Not checkedThe paper says movement span is the duration of life during which an individual can move with confidence, responsiveness, and adaptive control, and that it sits alongside lifespan and health span as a separate construct.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 3 of 6Not checkedThe article says movement span is nested within both lifespan and health span, and typically begins declining earlier than diagnosable health conditions.View evidenceHide evidence

Claim 4 of 6Not checkedIt describes early changes in movement span as slower reaction time, reduced balance recovery ability, and a preference for predictable movement environments.View evidenceHide evidence

Not checked

The source study was found, but this claim couldn't be checked against it.

Claim 5 of 6Not checkedThe article says gait speed has the strongest evidence base as a functional indicator of aging health, and recommends broader assessment with balance, reaction time, movement transitions, and the Timed Up and Go test.View evidenceHide evidence

Claim 6 of 6Not checkedThe framework is presented as having clinical, research, public health, and policy implications, including earlier warning for intervention before falls occur or health span is compromised.View evidenceHide evidence
