In view of such limitations the purpose of the current study was to examine whether passive hip rotation motion was different between people with and without LBP who regularly participated in a rotation-related recreational sport. A rotation-related sport is defined as one that requires repeated rotation of the trunk and hips to perform most aspects of the activity. We hypothesized that people with LBP would have less total hip rotation motion and more asymmetry of motion between sides than people without LBP. The current study is important because it may provide some insight into information that could be used to direct treatment, as well as provide some insight into potential prognostic variables for development of LBP that could be examined in future studies.
