It is seen that Posterior rotation of the innominate occurred with hip flexion in control subjects and pelvic pain subjects as previously reported in the literature.
In a study by Hungerford B et al; On the supporting leg, the innominate rotated posteriorly in controls and anteriorly in symptomatic subjects.
This study found that posterior rotation of the innominate occurred during weight bearing in controls. This movement pattern is thought to optimise stability of the pelvic girdle during increased loading. Conversely, anterior rotation occurred in symptomatic subjects during weight bearing. This is a non-optimal pattern and may indicate abnormal articular or neuromyofascial function during increased vertical loading through the pelvis.
