Sacroiliac 201: Dysfunction and Management A Biomechanical Solution

Posted on Posted in Richard L. Dontigny, PT, Volume 3 : Issue 2 : May 2011, Wonder Why?

By Richard L. Dontigny, PT ABSTRACT A commonly overlooked, reversible biomechanical vulnerability of the sacroiliac joints (SIJ) makes them subject to injury even through minor trauma. When the sacrum is loaded with the superincumbent weight, the pelvis is symmetrical and the line of gravity is posterior to the transverse acetabular axis, the pelvis has limited motion more »

Sacroiliac 101: Form and Function – A Biomechanical Study

Posted on Posted in Richard L. Dontigny, PT, Volume 3 : Issue 1 : February 2011, Wonder Why?

By Richard L. Dontigny, PT ABSTRACT The pelvis has been a puzzle that has consumed the greater part of my working life. The sacrum is the keystone of the puzzle, but does not function as a keystone. When the sacrum is loaded with the superincumbent weight and the joint is symmetrical, little or no movement has more »
