    Kinematic model indicating angles for HLR and lumbopelvic rotation. Abbreviations: α, HLR angle (in degrees); GT, greater trochanter marker; IC, iliac crest marker; K, knee marker; LM, lateral malleolus marker; θ, lumbopelvic rotation angle (in degrees).

    Angle of HLR and lumbopelvic rotation as a function of time. Abbreviations: LPR, lumbopelvic rotation; startdiff, difference in time between the start of HLR and lumbopelvic rotation.

  • Image Result
    Difference in start time of lumbopelvic rotation relative to start time of HLR, startdiff, during right versus left HLR for people in 2 LBP subgroups. (A) Relationship between right and left startdiff

    Difference in start time of lumbopelvic rotation relative to start time of HLR, startdiff, during right versus left HLR for people in 2 LBP subgroups. (A) Relationship between right and left startdiff* values for people in the lumbar rotation LBP subgroup. (B) Relationship between right and left startdiff* values for people in the lumbar rotation with extension LBP subgroup. *Startdiff value was normalized to HLR movement time.
