Stabilisasi SIJTerdapat 2 aspek yang dapat memberikan

stabilitas pada SIJ, yakni:1. Force closure:: muscle, fascia, 2. Form closure:: bone, ligament, joint3. Neural

Stabilisation of ligament on Weight transfer

Ligamen-ligamen pada SIJ

1. interoseus, posterior SI limit nutation and inferior shear of the sacrum

2. Long dorsal SI limit counternutation (commonly source of pain)

3. Sacrotuberous Ligament limit nutation of the sacrum). Attachment from tuber isciadicum to ILA. There’s connection between this ligament and Biceps femoris regarding the attachment on Tuber isciadicum.

Muscular function for optimal force closure

1. INNER MUSCLE/LOCAL MUSCLE

Provide stability trough increasing spinal segmental stiffness

Postural Tonic activity 10%

MCV (maximum mucle contraction)

2. OUTER MUSCLE/GLOBAL MUSCLE

Control spinal orientation
