Results: The regression model
revealed all of the questionnaires were more useful at identifying
participants who did not meet the minimum criteria for FAI
(No MC FAI = 95.7%, MC FAI = 55.6%, overall = 84.6%).
Based on the Wald criterion, the full model was reduced to the
CAIT, AII, and FAAM. The reduced model revealed the CAIT
(X2 = 8.756, p = 0.003) and AII (X2 = 31.992, p = 0.001) as
the only variables that had a significant relationship with the
outcome variable. Conclusion: The model illustrates no single
measure was able to predict if individuals met the minimally
accepted criteria for FAI. However, a significantly accurate
prediction of ankle stability status was produced by combining
the CAIT and AII. Clinical Relevance: Based on the results we
recommend that researchers and clinicians use both the CAIT
and AII to determine ankle stability status.
