“Asymmetry is the norm,” but it is also a component of soft-tissue changes of the paraspinal musculature, compensatory postures, and altered mechanics of the spine.25 Al-Eisa et al found that those with either a lateral pelvic tilt (LPT), where the ASIS and PSIS was higher on one side, or an iliac rotation asymmetry (IRA),where the ASIS was higher and PSIS was lower, demonstrated significant differences in coupled lumbar rotation during lateral flexion than those with normal symmetry.26,27 They concluded that subtle anatomic abnormalities of the pelvic bone alignment were associated with altered mechanics of the lumbar spine and that it may be a better indicator of functional deficit than absolute range of motion in individuals with lower back pain.26,27 Therefore, when evaluating patients, noting positional asymmetries is appropriate to have a means of future comparison and also to assist in the formation of a functional diagnosis that is unique to each patient.
