The impact of diabetes on physical function pose a challenge in
assessing clinical outcomes.
The purpose of this study was to provide
evidence of responsiveness for the foot and ankle ability measures (FAAM) in
individuals with diabetes mellitus. The two most recent FAAM scores of
155 diabetic patients treated for foot/ankle pathology were analyzed. Based on
physical component summary (PCS) scores of the SF-36, subjects were categorized
as improved (>7-point positive change), worsened (>7-point negative change), or
unchanged (<7-point change). Analyses of the worsened and improved groups were
compared to the unchanged group using two-way repeated measures ANOVAs and ROC
curve analyses. RESULTS: The ANOVAs demonstrated a significant difference between
groups (P=0.001). ROC curves analysis for detecting an improvement or decline in
status were 0.73 (95% CI 0.62-0.84) and 0.70 (95% CI 0.59-0.81), respectively. An
increase in FAAM score of 9 points represented the minimal clinically important
difference (MCID) with 0.64 sensitivity and 0.78 specificity. A decrease in FAAM
score of 2 points represented a MCID with 0.65 sensitivity and 0.61 specificity.
CONCLUSIONS: The FAAM demonstrated responsiveness to change in individuals with
orthopedic foot and ankle dysfunction complicated by diabetes and can be used to
measure patient outcomes over a 6-month period.
