Responses range from 1 (unable to perform at all) to 4 (normal). If not applicable then the item was scored as 0.
total score =
= SUM(points for all 9 items)
total score if less than 9 items completed =
= SUM(points of applicable items) * (9 / (9 – (number of nonapplicable items)))
Interpretation:
• minimum score: 0 (none of the items applicable)
• minimum score with all items applicable: 9
• maximum score with all items applicable: 36
• The higher the score, the better a person's functional ability.
Performance (page 375):
• Validity: The scale shows face validity, with scores varying with clinical severity. The score also correlates well with the Rankin scale.
• Reliability: Reliability was good for inter- and intra-observer scoring.
• Responsiveness: The Rotterdam score increased in patients who responded to therapy. The standardized response mean indicated good responsiveness in these patients.
