where:
• Motor performance is graded with the extremity outstretched; the ability to resist gravity is timed for 10 seconds
• Complete definitions for the parameters are available from the authors (Department of Neurology, University of Cincinnati Medical Center, 231 Bethesda Avenue, Cincinnati, Ohio 45267-0525).
clinical stroke scale score =
= SUM(parameter points)
Interpretation:
• minimum score: 0
• maximum score: 36
• The higher the score, the more severe the infarct and the worse prognosis.
• There are 9 combinations for the clinical status changes (S S, S B, S W, etc.)
