AIS Linked to Abnormal Pronation.pdf (original) (raw)

2013, Preliminary Study - Adolescent Idiopathic Scoliosis Lined to Abnormal Foot Pronation

In a preliminary study of 25 teenage patients with asymmetrical abnormal pronation patterns and a positive Adams Test, a positive statistical correlation was found between the pronation pattern, the pelvic distortion pattern, and the pattern of frontal plane deviation within the thoracic spine.

Variation in pelvic morphology may prevent the identification of anterior pelvic tilt

The Journal of manual & manipulative therapy, 2008

Pelvic tilt is often quantified using the angle between the horizontal and a line connecting the anterior superior iliac spine (ASIS) and the posterior superior iliac spine (PSIS). Although this angle is determined by the balance of muscular and ligamentous forces acting between the pelvis and adjacent segments, it could also be influenced by variations in pelvic morphology. The primary objective of this anatomical study was to establish how such variation may affect the ASIS-PSIS measure of pelvic tilt. In addition, we also investigated how variability in pelvic landmarks may influence measures of innominate rotational asymmetry and measures of pelvic height. Thirty cadaver pelves were used for the study. Each specimen was positioned in a fixed anatomical reference position and the angle between the ASIS and PSIS measured bilaterally. In addition, side-to-side differences in the height of the innominate bone were recorded. The study found a range of values for the ASIS-PSIS of 0-23...
