The present review shows that current scientific literature concerning the usability of orthopaedic shoes focuses mainly on effectiveness at the expense of the other domains of usability , i.e. , efficiency , satisfaction and context of use
Objective : To determine the method ological quality of studies evaluating  orthopaedic shoes and orthopaedic shoe provisions .
To what extent do studies evaluating  orthopaedic shoes prescribed for patients with degenerative disorders of the foot , rheumatoid arthritis , diabetes mellitus and neurological foot disorders , focus on the aspects of the International Organization for St and ardization ( ISO ) definition of usability , i.e. , effectiveness , efficiency , satisfaction , and context of use ?
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
