Note: Examination was undertaken in supine unless otherwise indicated (P: prone). Medial and lateral rotation (MR and LR) range of movement tests were undertaken following the Khan protocol.22 The maximum isometric contraction (MI) was undertaken using a fixed dynamometer with the participant's limbs and pelvis were stabilised using non-elastic straps. FABER and Ober tests were undertaken following the Woodley protocol,7 with participants asked if the test was painful, and then asked to identify where the pain was located.
AAR, assessor-applied resistance—maximum isometric contraction (manual resistance); AROM, active range of movement; FABER, flexion abduction external rotation; MI, maximum isometric contraction (fixed dynamometer applied resistance); PROM, passive range of movement.
✓: Test undertaken; X: Test not undertaken.
*Included in classification tree as a single variable.
‡,†,§Indicated that the two tests identified by the symbol were considered with an either or result. For example, ‡Indicates that the results from AAR for LR in 0° flexion and MI for LR in 90° flexion were considered together. That is, a positive result from either of these tests was considered a positive result for resisted LR.
