segmental identification (trunk, pelvis, thighs, and legs; Robertson, Caldwell, Hamill, Kamen, & Whittlesey, 2004 ). This marker placement combination provided for a static calibration, referenced to the laboratory space, which was used to construct an eight-segment kinematic model (head-arms-trunk, pelvis

individuals with LBP have symptoms that are secondary to SIJ involvement. 18 SIJ stability is complex with a self-locking mechanism created by form closure (via the shape of bony anatomy) and force closure (via muscle supporting the pelvis). 19 The SIJ is critical for transferring loads between the lower

Based on this qualitative study, the ATM process is clearly structured as a motor-learning process as it contains the classic elements of repetition

with ACL injury. 18 However, little is known of the effect of ACL injury on hip muscle activity. The muscles of the hip joint, specifically the gluteal muscle group, play a pivotal role in lower-extremity kinematics. 19 For example, the gluteus medius (GMED) stabilizes the pelvis and controls femoral
