The Claim
The 30-second chair-stand test (30s-CST) is significantly correlated with walking ability and dynamic balance in acutely admitted older adults, with correlation coefficients of r = 0.55 and r = 0.69, respectively, when compared to corresponding DEMMI subsets; however, these correlation values do not meet the threshold for acceptable concurrent validity, which is defined as r > 0.70.
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 just admitted to the hospital, how well they can stand up from a chair 30 times in 30 seconds is linked to their walking and balance, but the link isn’t strong enough to use the test as a reliable measure on its own.
See the scientific wording
The 30-second chair-stand test (30s-CST) is significantly associated with both walking ability and dynamic balance in acutely admitted older adults, as shown by correlations of r = 0.55 and r = 0.69 with the respective DEMMI subsets, though these associations fall below the threshold for acceptable concurrent validity (r > 0.70).
What the research says
1 studyThe study looks at the same test and patients as the claim and finds it is linked to walking and balance, though not perfectly. It agrees the test works, but thinks it's good enough to use.
