title: The prevalence of postural asymmetry in people with and without chronic low back pain.
abstract: OBJECTIVE
  To determine the extent of pelvic obliquity and lateral sacral base angle in subjects with and without chronic low back pain (LBP) by using postural radiographs.
  
  
  METHODS
  Cross-sectional, controlled.
  
  
  METHODS
  A Veterans Administration hospital.
  
  
  METHODS
  Veterans and employees with (n=93) and without (n=76) chronic LBP.
  
  
  METHODS
  Postural radiographs.
  
  
  METHODS
  Differences between the mean extent of pelvic obliquity and the lateral sacral base angle in subjects with and without chronic LBP.
  
  
  RESULTS
  The z scores showed no significant statistical differences in the extent of pelvic obliquity or lateral sacral angle in subjects with and without chronic LBP.
  
  
  CONCLUSIONS
  Correction of pelvic obliquity by the use of heel lifts has been used as a modality of treatment for patients with chronic LBP. The majority of the patients in our clinics for whom this modality is used report at least some improvement in their pain symptoms. Because the extent of pelvic obliquity is similar in the subjects with and without chronic LBP, other factors must account for those who benefit from correction of their pelvic obliquity.
