Scrutinio et al reported models for predicting functional outcomes after stroke rehabilitation. One model predicts motor functional independence and a second predicts ability to perform activities of daily living. The authors are from IstitutiClinicaScientifici Maugeri-SPA and other institutions in Italy.
Patient selection: stroke patient after stroke rehabilitation
Outcome: probability of a motor-FIM score > 61 at discharge (defines a mild stroke impairment)
Parameters:
(1) age in years
(2) time since stroke occurrence to rehabilitation admission in days
(3) unilateral neglect (referred to neglect in example)
(4) motor-FIM score, from 13 to 91
(5) cognitive FIM score, from 5 to 35
