PMID 37721097WHAT IT FOUND
The supine-to-stand test was reliable when the same or different raters tested it and when repeated after 7 days.
People with stroke averaged 10.81 seconds, compared with 4.57 seconds in healthy older adults. A 5.25 second cut-off separated the groups.
Key findings
01The supine-to-stand test had excellent reliability in people with stroke when the same rater tested them, when two raters tested them, and when the test was repeated after 7 days.
02People with stroke took 10.81 seconds on average to stand from supine, compared with 4.57 seconds for healthy older adults, and a 5.25 second cut-off had 81.1% sensitivity and 84% specificity.
03STST time was correlated with Berg Balance score, Six-Minute Walk distance, Timed Up and Go time, and limits of stability excursion scores.

What it does not show
The people with stroke had relatively high cognitive and motor function, so the results may not apply to more impaired patients. Movement quality was not scored, although 26 of 52 people with stroke used a stool for support. The sample size was estimated from reliability in Parkinson's disease, not from stroke. The test protocol used here is not standardized across the literature, because earlier studies used different settings and trial numbers. The study compared people with stroke with healthy older adults, so the 5.25 second cut-off does not show that the test diagnoses stroke in a clinic. The design was cross-sectional, so correlations do not show that changes in test time reflect recovery.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not use the 5.25 second cut-off as a test for stroke. It separated the people with stroke in this study from healthy older adults, and the stroke group had relatively high cognitive and motor function.
