Stabilisasi SIJ
 Terdapat 2 aspek yang dapat memberikan stabilitas
pada SIJ, yakni:
1. Force closure:: muscle, fascia,
2. Form closure:: bone, ligament, joint
3. Neural

Posterior view of SIJ

Stabilisation of ligament on Weight transfer

Ligamen-ligamen pada SIJ
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 2. OUTER MUSCLE/GLOBAL MUSCLE

Provide stability trough
increasing spinal
segmental stiffness
Postural
Tonic activity 10% MCV
(maximum mucle
contraction)


 Control spinal orientation
 Phasic
 Anatomically more
superficial
8
Core muscle
9
Transversus abdominis
 Deepest of the abdominal muscles
 Fibers are horizontally oriented
 Contraction increases intra-abdominal pressure
 Stiffens the lumbar spine
 TrA muscles active before movement on upper and
lower extremity
 How to palpate this muscles??  seated with finger 1’
inferior and medial ASIS

Relationship between pelvic
anterior tilt and lordosis lumbal

assessment
 Subjective assessment
 Objective assessment
 Observation, palpation
 AROM Lx
 Standing flexion
 Seated flexion
 Stork test
 Squish test
 SLR
15
Anterior rotation of inominate
 ASIS more anterior and inferior
 Shorten and strong rectus femoris
 Lumbal segment on side more deeper
 Hamstring in stretch posistion (may be weak because
it’s position)
16
Posterior rotation of inominate
 ASIS more superior
 Tight hamstring
 Long dorsal SI in tension?
 Lumbal segment more deeper on contralateral side
