PMID 37404979WHAT IT FOUND
In 41 people after stroke, how fast they reached to a target estimated arm motor scores.
At home, a model using final reaching performance estimated about 70% of score differences, but unsupervised performance was less consistent.
Key findings
01The reaching exercise was the strongest single predictor of UEFM scores among the 12 exercises performed in clinic.
02In clinic data, the best validated single-exercise model estimated UEFM scores with an error estimate of 6.22 points on the 66-point scale.
03For home use, a model refit to final reaching performance and end-of-therapy UEFM scores had a validated error estimate of 8.70 points.

What it does not show
41 people in clinic and 14 people at home, so the estimates are from a small sample. Home participants were not given explicit instructions on which exercises to perform, so exercise patterns varied. At home, puck placement was not standardized and participants were unsupervised, so movement quality could differ. The clinic model has a floor effect for UEFM scores below 14. Home participants were all subacute, so chronic stroke users may not fit the model. The home FitMi group included no female participants. The authors state that test-retest reliability and sensitivity to change need further research.
The easy way to misread this
Do not use this as a validated clinical assessment. It is an exploratory model from a small sample, and the authors state further work is needed on test-retest reliability and sensitivity to change.
