What does a dysfunctional pelvis look like? Well generally it would probably appear no different to a fully functioning one. Someone trained in pelvic biomechanics can do a few manual screens to assess whether your pelvis moves freely around the sacro-illiac joint (SIJ). If it doesnt, chances are you will present with a twist or rotated pelvis caused by sub clinical muscle spasm in small muscles like piriformis (which crosses over the SIJ). This in turn gives the appearance of a functional leg length difference (LLD) meaning it is not a structural difference in bone lengths for example. It does mean it is correctable if you can release the muscle spasm though. What symptoms might I expect, if any, with a functional LLD? While this may present as a very small difference in leg length, over time this asymmetry requires the body to compensate for it. The body compensates generally in a zig zag fashion, in that the right pelvis can directly influence the left shoulder or foot for example. Not everyone with pelvic dysfunction is symptomatic but many can suffer with low back pain due to the pelvic twist causing functional scoliosis of the spine which in turn loads the facet joints which in turn are supposed to protect the discs. Another common complaint is knee pain. This could be on the longer leg which may have to bend more to compensate for the fact it is being held long by the twist in the pelvis. The symptoms may even occur in the opposite shoulder through the kinetic chains linking hamstring muscles (which attach to the pelvis) to the thoraco lumbar fascia in the lower back which continues into the latissimus dorsi muscle which ends up in the humerus of the upper arm. read more... biomechanicseducation/site/blog/210-pelvic-biomechanics
