Presentation Transcript

  1. Sacroiliac joint(part 1) Presented by: Abdul Rasid

  2. Stabilisasi SIJ • Terdapat 2 aspek yang dapatmemberikanstabilitaspada SIJ, yakni: • Force closure:: muscle, fascia, • Form closure:: bone, ligament, joint • Neural

  3. Posterior view of SIJ

  4. Stabilisation of ligament on Weight transfer

  5. Ligamen-ligamenpada SIJ • interoseus, posterior SI  limit nutation and inferior shear of the sacrum • Long dorsal SI  limit counternutation (commonly source of pain) • 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.

  6. Sacral movement on inominate

  7. Muscular function for optimal force closure • 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 • Phasic • Anatomically more superficial

  8. Core muscle

  9. Transversusabdominis • 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

  10. Posterior oblique sling

  11. Resultangayamuscle sling

  12. Relationship between pelvic anterior tilt and lordosislumbal

  13. assessment • Subjective assessment • Objective assessment • Observation, palpation • AROM Lx • Standing flexion • Seated flexion • Stork test • Squish test • SLR

  14. 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)

  15. Posterior rotation of inominate • ASIS more superior • Tight hamstring • Long dorsal SI in tension? • Lumbal segment more deeper on contralateral side
