The Claim
The 30-second chair-stand test (30s-CST) exhibits a pronounced floor effect in acutely admitted older adults, with 60% of patients completing zero repetitions at admission, which limits its sensitivity to detect functional decline or improvement in individuals with the lowest physical performance levels.
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.
A lot of older patients in the hospital can't do even one sit-to-stand in 30 seconds, so this test isn't great at tracking whether they're getting worse or better when they start off very weak.

What the research says
1 studyThe study found that the chair-stand test often gives the lowest possible score to many weak older patients, making it hard to tell if they’re getting worse or better over time.
