Still relevant years after its publication, this article offers an overview of the correctable factors that contribute to chronic SI pain. Looks at ligamentous laxity, how to correct hypermobility, how to use IASTM of pelvic ligaments and tendons, and why to use low force manipulation.
Sacro-Iliac Revisited, the Importance of Ligamentous Integrity
Looks at the ligaments of the sacro-iliac and the utility of instrument-assisted soft tissue mobilization (Graston technique) in correcting long standing SI hypermobility problems.
