hip-flexors, quads and strengthening the abdominal muscles, hamstrings, and glutes. strengthening the gluteal complex is a commonly accepted practice to reverse excessive lumbar lordosis, as an increase in gluteal muscle tone assists in the reduction of excessive anterior pelvic tilt and lumbar hyperlordosis. local intra-articular hip pain has been shown to inhibit gluteal contraction potential, meaning that hip pain could be a main contributing factor to gluteal inhibition. dancers should ensure that they don't strain themselves during dance rehearsals and performances. to help with lifts, the concept of isometric contraction, during which the length of the muscle remains the same during contraction, is important for stability and posture. lumbar hyperlordosis may be treated by strengthening the hip extensors on the back of the thighs, and by stretching the hip flexors on the front of the thighs. only the muscles on the front and the back of the thighs can rotate the pelvis forward or backward while in a standing position because they can discharge the force on the ground through the legs and feet. abdominal muscles and erector spinae can't discharge force on an anchor point while standing, unless one is holding his hands somewhere, hence their function will be to flex or extend the torso, not the hip. back hyper-extensions on a roman chair or the inflatable ball will strengthen all the posterior chain and will treat hyperlordosis. so too will stiff-legged deadlifts and supine hip lifts and any other similar movement strengthen the posterior chain without involving the hip flexors in the front of the thighs. abdominal exercises could be avoided altogether if they stimulate too much the psoas and the other hip flexors. controversy regarding the degree to which manipulative therapy can help a patient still exists. if therapeutic measures reduce symptoms, but not the measurable degree of lordotic curvature, this could be viewed as a successful outcome of treatment, though based solely on subjective data. the presence of measurable abnormality does not automatically equate with a level of reported symptoms. braces the boston brace is a plastic exterior that can be made with a small amount of lordosis to minimize stresses on discs that have experienced herniated discs. in the case where ehlers danlos syndrome (eds) is responsible, being properly fitted with a customized brace may be a solution to avoid strain and limit the frequency of instability. tai chi while not really a 'treatment', the art of tai chi chuan calls for adjusting the lower back curvature (as well as the rest of the spinal curvatures) through specific re-alignments of the pelvis to the thighs, it's referred to in shorthand as 'dropping the tailbone'. the specifics of the structural change are school specific and are part of the jibengong (essential technique) of these schools. the adjustment is referred to in tai chi chuan literature as 'when the lowest vertebrae are plumb erect...'
