Category 2
Sacro iliac weight-bearing dysfunction
Cat 2 flow
Lower extremity psoas and iliofemoral, scaral cup, trap fibers
UMS/LLL - yes = block cat 2,
no = check and adjust C1 and L5
UMS/LLL - yes = block cat 2
No = manually adjust SI joint
Strong arm fossa? Yes = stairstep and figure 8 long leg, short leg
No = basic II cranial
Thickest and strongest ligament of the joint
Interosseous ligament of the sacroiliac joint
Largest syndesmosis in the body and dwarfs the relative size of the auricular surfaces
Interosseous sacroiliac ligament
This ligament is thought to strongly resist joint separation as well as vertical and anteroposterior translations
Interosseous sacroiliac ligament
Cycle initiated by chronic somatic dysfucntion, which may result in muscle atrophy which can be further expected to reduce proprioceptive output from atrophied muscles. The lack of proprioceptive inhibition of nociceptors at the dorsal horn of the spinal cord would result in chronic pain and a loss of standing balance
Study suggest relationship between chronic pain, somatic dysfucntion, muscle atrophy and standing balance
Discs are not a significant cause of ___ SI joint dysfucntions are very common cause of __
Low back pain
The ___ is 20 times more vulnerable to axial compression and twice as susceptible to axial overloading as lumbar segment
Bending, lifting, twisting
SI joint
SI joint dysfunction have been demonstrated to be the major biomechanical cause of
Lumbar disc degeneration
In study of 1000 consecutive patients with low back pain, ___ had a mechanical dysfunction of the sacroiliac joints as a major cause of their LBP
98%
The presence ofunilateral low back pain alerts the clinician that a patient may have a
SI problem
Of 88 patient with LBP, __ had evidence of SI joint dysfunction
71
If a dysfunction of the SIJ’s were to compromise the movement of the sacrum, this would cause a
Considerable increase in the shear forces on the disc
SIJ dysfunction has been demonstrated to be the major cause of
Lumbar disc degeneration
In sports requiring repetitive, unidirectional movement, _____ is understandable
Pelvic shear and/or torsional force is understandalbe
The SI joint is reported as a common source of __ in school children
LBP
If the SIJ is incompetent, the NS is intact, the muscle strength to control pelvic position will be inhibited due to reflex activity. Can be implied by
Diminished motor performance of muscles which control pelvic position
Leg length differences may be the prime cause of ___
SIJ complaints
Only tests for ___ had consistently acceptable results
Palpation for pain
Lumbar mopal might be valid but had poor
Reliability
SI joint mopal seems slightly reliable, but literature does not show
Validity
Leg checks correlated with radiographic measurements, but consensus on method and interpretation is
Lacking
In females, pelvic floor muscles have the capacity to
Increase stiffness of the pelvic ring. And can generate a backward rotation of the sacrum in both sexes
Tucking chin exacerbates
Posterior occiput and reduces atlas dysfunction
