Force Closure - Glossary Term Illustration

Force Closure

Force closure is a term used to describe the increase in joint stability via compressive forces resulting from muscular contraction and increased tension in fascial structures. This concept is often applied to the core intrinsic stabilizers, thoracolumbar fascia, and the sacroiliac joint. Forcing closure is an essential component of load transfer from the spine to the legs. For example, the stability of the sacroiliac joint is due to the muscle supporting it (force closure) and the shape of the sacrum and ilium (form closure). Related terms: load transfer, fascia, sacroiliac joint, stabilizers, lumbopelvic pain.

Force Closure

Force Closure: An increase in joint stability via compressive forces resulting from muscular contraction and increased tension in fascial structures (1, 2). This term is most often used in reference to core intrinsic stabilizers, the thoracolumbar fascia, and the sacroiliac joint. For example, the stability of the sacroiliac joint is due to the muscles supporting it (force closure), and the shape of the sacrum and ilium (form closure)
