In both studies, players with LBP displayed asymmetry of hip medial rotation between the lead and non-lead hip that was not present in players without LBP. Asymmetries of motion were also found with the FABERE test
In the FABERE test the hip is passively flexed to place the foot on the opposite knee and then maximally abducted, laterally rotated and extended. Although not a specific measure of hip lateral rotation, the authors suggested that the FABERE test findings indicated a potential difference in the amount of hip lateral rotation between sides in the LBP group that was not present in the group without LBP.
