Hip abduction: Meant to assess quality of the pelvic muscles and give information about the stabilization of the pelvis during gait. The test is performed with the patient lying on one side, the lowermost leg bent and one hand is flat on the table for stability. The patient is asked to abduct the uppermost leg (that is straight in relation to the trunk) about 20° and the examiner stands behind the patient to observe possible faulty movements.

The normal movement consist of abducting the leg straight up with no additional movements of hip, trunk and leg. A tight tensor fascia latae muscle will result in hip flexion, while an early lateral pelvic tilt is sign of atrophic gluteals because the muscle quadratus lumborum is acting before them (Page et al, 1967).
