Role of pelvic asymmetry in skeletal posture

Abstract

Abstract

Objective

The reversible nature of pelvic obliquity and its relationship with leg length difference and functional scoliosis have not been sufficiently evaluated. This study aimed to ascertain the manifestations of asymmetry in skeletal posture, and the outcome of three novel patient-performed maneuvers, each directed at one of the three expressions of pelvic obliquity: iliac asymmetry, sacral torsion, and iliosacral inflare/outflare.

Methods

This study was set in a physiatric practice and comprised 103 consecutive first-visit patients (male 37, female 66, age 12-80 years). Palpation Meter® was used to examine the iliac crests and inferior scapular angles. The patients performed a separate self-correcting muscle-energy maneuver for each of the three conditions.

Results

The correcting maneuvers were effective in all cases. Reversible pelvic obliquity was found in 100/103 patients (96.2%).  Iliac asymmetry was caused by an anteriorly rotated ilium in 51% of the patients, with ipsilateral leg lengthening; 49% had an upslip of the ilium causing a shortening of the leg, 51% had a follow-up visit, and 84% achieved alignment in all three respects.

Conclusion

Reversible pelvic obliquity is common but often overlooked in patients with musculoskeletal pain. This study proposes an alternative to manual treatment procedures for this condition.
