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 .
Comparative responsiveness of generic versus disease-specific and weighted versus unweighted health status measures in carpal tunnel syndrome.
OBJECTIVES The authors evaluated the relative responsiveness to change of generic versus disease-specific and unweighted versus weighted health status measures in carpal tunnel syndrome ( CTS ) . METHODS Data were obtained from 196 subjects followed in a prospect i ve community-based cohort study in Maine who underwent carpal tunnel release ( The Maine Carpal Tunnel Syndrome Study ) . Patients were evaluated before and 6 months after surgery . The disease-specific , unweighted severity score was derived from the vali date d Carpal Tunnel Syndrome Assessment Question naire . Patients were asked to rate the importance of each symptom included in the severity score . Each severity question was weighted by its importance , creating a disease-specific weighted score . Generic instruments were the SF-36 , SF-12 , and a  Quality of Life Rating Scale .  Sensitivity to change was calculated with the st and ardized response mean ( SRM , mean change/st and ard deviation of change ) as well as the effect size ( ES , mean change/st and ard deviation of baseline values ) . The ability of the instruments to distinguish clinical ly important differences was assessed by correlating the changes in scores with global ratings on satisfaction and perceived improvement as external criteria . RESULTS The disease-specific weighted score ( SRM : 1.56 , ES : 1.99 ) was more responsive than the unweighted score ( SRM : 1.36 , ES : 1.57 ) . The Quality of Life Rating Scale , SF-36 , and SF-12 subscales were less sensitive to change , with st and ardized response means and effect sizes that ranged from -0.23 to 0.88 . The ability to distinguish clinical ly important differences was higher for the two disease-specific scales . The coefficients of correlation with the external criteria ranged from 0.50 to 0.56 for the unweighted score and 0.56 to 0.62 for the weighted score and were significantly stronger than the correlations between external measures and the most responsive subscale of the SF-36 ( Bodily Pain subscale , r = 0.36 ) . The SF-12 health survey performed as well as the SF-36 in term of responsiveness and ability to distinguish clinical ly important change . CONCLUSIONS Disease-specific measures were superior to generic measures in capturing clinical change after carpal tunnel release , and a weighted score was slightly more responsive than the unweighted score . The SF-12 showed comparable psychometric properties compared with the longer 36-item Short-Form Survey
