Objectives:
(I) To obtain biomechanical parameters and assessment scores applied at a very early stage after stroke that predict best the functional outcome after rehabilitation. (II) To evaluate the predictive value of changes (i.e. increase or decrease) of these parameters during the first week in relation to the predictive value of their absolute scores.
Design:
Prospective outcome study.
Subjects:
Forty-one stroke patients, admitted to the stroke unit within 24 hours.
Main Outcome Measures:
Barthel Index, Rivermead Motor Assessment, Motor Club Assessment and Functional movement activities, NIH-Stroke scale (NIH-SS), Grip strength.
Results:
Parameters assessed within the first hours after stroke correlated only weakly with the outcome. The best model predicting functional outcome and independence in activities of daily living of stroke patients after 6 months was that including NIH-SS, grip strength, age and previous stroke explaining 79% of the variance. These parameters assessed on day 7 post-stroke are more predictive than the difference between stroke onset and day 7 post-stroke.
Conclusion:
Parameters for predicting outcome should not be assessed before day 7 post-stroke.
