The effect of lumbopelvic region rotation relative flexibility on thorax–pelvis and pelvis–femur coordination during walking

The relationship of peak ankle dorsiflexion angle with lower extremity biomechanics during walking

“…As the pelvis is connected to the spine, changes in pelvic kinematics may also be associated with lumbosacral injuries. A lower pelvic rotation angle leads to lumbopelvic region stiffness during walking, which is associated with the onset and progression of low back pain [ 37 ]. In addition, restricted pelvic rotation during walking also significantly reduces stride and step length, as well as gait speed [ 38 ].…”

“…Functional limited ankle dorsiflexion was associated with decreased lower extremity activity in the sagittal plane and increased activity in the frontal and transverse planes appearing as compensatory activity, along with decreased forward propulsion of the lower extremity. Functional limited ankle dorsiflexion resulting in biomechanical changes may lead to a range of adverse effects including impaired balance, reduced step speed [ 24 ] and shortened stride length [ 13 ], as well as knee osteoarthritis [ 26 ], patellofemoral pain [ 29 , 35 ], iliotibial band syndrome [ 33 , 34 ], hip osteoarthritis [ 31 , 32 ], and low back pain [ 37 ]. However, how to assess functional limited ankle dorsiflexion is a challenge.…”
