The Claim
In older adults admitted to an emergency department short-stay unit, the 30-second chair-stand test (30s-CST) is strongly positively correlated with the de Morton Mobility Index (DEMMI), with each additional chair stand associated with an average 4.9-point increase in DEMMI score (r = 0.72), indicating concurrent validity as a measure of overall physical performance at admission.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
For older adults in the ER, how many times they can stand up from a chair in 30 seconds is closely linked to their overall mobility — each extra stand means nearly a 5-point boost in their mobility score.

What the research says
1 studyThe study shows that the chair-stand test really does match well with a standard mobility test in older emergency patients, and each extra stand is linked to a nearly 5-point boost in mobility scores, just like the claim says.
