The Edinburgh Prognostic Score is used to assess patients following stroke.
Stroke is defined as acute onset of neurological deficit lasting more than 24 hours or leading to death with no apparent cause other than cerebrovascular disease.
Parameters:
(1) motor deficit
(2) proprioception
(3) balance
Timing: determined at 1, 2 and 4 weeks after stroke

Edinburgh prognostic score =
= 1.6 + (points for motor deficit) + (points for proprioception) + (points for balance)
Interpretation:
• minimum score: 1.6
• maximum score: 5.6
• The lower the score the better.
Correlation with Barthel ADL score at discharge or 16 weeks:
(1) The predictive value of the Edinburgh score diminishes significantly with dementia.
(2) The Edinburgh score measured at 1 week after stroke does not correlate significantly with the Barthel score.
(3) The Edinburgh score at 2 or 4 weeks after stroke does correlate with the Barthel score as follows:
predicted Barthel score at discharge or 16 weeks after stroke =
= 23.07 - (3.69 * (Edinburgh score))
