Low back pain (LBP) is a common complaint in the adult population. A study in 2002 found that the percentage of people reporting LBP over a 3-month period corresponded to over 54 million American adults. 1,2 Popular treatment methods for LBP include manual therapy, stretching and core stabilization. 3 Manual therapy is a form of conservative treatment with the aim to reduce pain and increase function through handson techniques by a clinician. 4 Manual therapy treatments include soft tissue massage, traction, stretching, joint mobilization, instrument assisted soft tissue mobilization (IASTM) and muscle energy techniques (MET). 5 One cause of LBP that can be treated with manual therapy occurs from a unilateral innominate rotation. A unilateral innominate rotation can occur when musculature of the abdomen, hip flexors, hip extensors, and back extensors are unbalanced. 6,7 If a patient presents with a unilateral anterior innominate rotation, the ipsilateral hip flexors are often tight and shortened, while the ipsilateral hip extensors are weak and lengthened. In a unilateral posterior innominate rotation, the ipsilateral hip flexors are weak and lengthened, while the ipsilateral hip extensors are tight and shortened. 8 For example, in a unilateral anterior innominate rotation, the ipsilateral rectus femoris and erector spinae are inflexible. 6
