While there are many different scoring systems available for foot and ankle specialists to use to assess or demonstrate the effectiveness of treatments , the AOFAS , while it is an unvali date d scoring system , is the most commonly used scoring system in this review .
This review presents data about commonly used patient reported outcomes systems in foot and ankle surgery .
The goal of this systematic review is to determine the most commonly used outcome measurement tools used by foot and ankle specialists and determine their limitations , such as whether they are vali date d , have floor/ceiling effects , and so on .
The Foot Function Index: a measure of foot pain and disability.
A Foot Function Index ( FFI ) was developed to measure the impact of foot pathology on function in terms of pain , disability and activity restriction . The FFI is a self-administered index consisting of 23 items divided into 3 sub-scales . Both total and sub-scale scores are produced . The FFI was examined for test-retest reliability , internal consistency , and construct and criterion validity . A total of 87 patients with rheumatoid arthritis were used in the study .  Test-retest reliability of the FFI total and sub-scale scores ranged from 0.87 to 0.69 . Internal consistency ranged from 0.96 to 0.73 . With the exception of two items , factor analysis supported the construct validity of the total index and the sub-scales . Strong correlation between the FFI total and sub-scale scores and clinical measures of foot pathology supported the criterion validity of the index . The FFI should prove useful for both clinical and research purpose
