Foot and Ankle Disability Index (FADI) score calculator

About the score:

Originally published in 1999 in the Journal of Orthopaedic & Sports Physical Therapy, the Foot and Ankle Disability Index (FADI) was developed to assess functional limitations of those with a variety of foot and ankle conditions.

The FADI is a patient-completed instrument that consists of the “FADI” subscale (26 scored items) and a “FADI Sports” subscale (8 scored items), in which the response options are presented as 5-point rating scales (range 0 to 4). Scores for each subscale range from 0% (most disability) to 100% (least disability).
