Creemers et al developed a Dutch version for the functional index (FI) of Dougados et al in patients with ankylosing spondylitis. This can be used to monitor the functional capacity of a patient with ankylosing spondylitis over time and to evaluate the effectiveness of therapeutic interventions. The authors are from Nijmegen in The Netherlands.

Items from the French (Dougados et al) index: 1, 2, 3 (split), 4, 5, 6, 7, 8, 9, 10, 11, 12 (split), 13, 18, 19 (split), 21, 22, 23, 25, 26, 27, 28, 29 (split)
Number of items added: stated 15, although my count of items from the French was 21 (without splitting), meaning 16 may have been added, or else one additional item was from the French Index.

where:
• A grading scheme with no problem, slight problem, moderate problem, severe problem and impossible as responses would seem feasible.
• Up to 3 items were allowed to be omitted, but the questionnaire was not evaluated if 4 or more items were omitted.
total score =
= SUM(points for all statement answered)
average score =
= (total score) / (number of statements answered)
Interpretation:
• minimum score: 0
• maximum total score: 140
• maximum average score: 4
• The higher the score the worse the functional impact.
Purpose: To evaluate the functional ability of a patient with ankylosing spondylitis using the Dutch Functional Index (DFI-AS).
Specialty: Sports Medicine & Rehabilitation, Immunology/Rheumatology
Objective: response to therapy, disease progression, disability and performance
ICD-10: M45,
