The objective of this study was to evaluate the interrater reliability of the FABER test, flexion-internal rotation-adduction impingement test, log roll test, and the palpation of the greater trochanter for tenderness. Seventy subjects were evaluated prospectively by an orthopaedic surgeon and physical therapist. Kappa coefficients with 95% confidence intervals were as follows: FABER test kappa was 0.63; flexion-internal rotation-adduction impingement test kappa was 0.58; log roll test kappa was 0.61; and greater trochanteric tenderness kappa was 0.66.
The kappa values for the FABER test, log roll test, and assessment of greater trochanteric tenderness were greater than 0.40 (fair level of agreement) at a 95% confidence level. The low reliability obtained for the flexion-internal rotation-adduction impingement test may be related to a prevalence concern.
