The Recovery Model Faltered Where Patients Needed Certainty Most
External validation preserved average error but exposed systematic underprediction for severe upper-limb impairment.
Summary
External validation preserved average error but exposed systematic underprediction for severe upper-limb impairment.
A stroke-recovery model trained in a Dutch cohort was tested in an independent Danish prospective cohort of 80 patients about two weeks after stroke. Median absolute error was statistically comparable to development results, and calibration was close to ideal above predicted Action Research Arm Test scores of 40. Lower ranges were systematically underpredicted, showing that additional predictors are needed before clinical implementation for severely impaired patients.
