Pelvic Asymmetry
Quite often one side of the pelvis is higher than the other, which also produces apparent uneven leg length. This asymmetry is usually due to weakness in some muscles of the pelvis and overactivity in others. The overactive muscles can cause pain. The asymmetry can cause back pain. Having a level pelvis is important if the spine is to be comfortable. Pelvic symmetry can also be important in reducing hip and knee pain.
