Scoring is based on the best score at each level.
The timing of the neurologic exam appears to be the first 15 days post injury.
full score =
= SUM(points for all 5 parameters)
Interpretation:
• minimum score: -10
• maximum full score: 40
X =
= (0.267 * (full score)) - 3.279
probability of independent walking =
= 1 / (1 + EXP((-1) * (X))
Performance:
• The area under the ROC curve was 0.96 for the full score.
