SIJ - QL ligament - function

Stabilizes SI jt
Rectus abdominus
- From xiphoid to pubic symphysis
- Flexes trunk & posteriorly tilts pelvis
External oblique - action
- ///
- U/L - IPSI Lateral flexion/ CONTRA rotation of trunk /IPSI hip rotation
Internal oblique - action
- ///
- IPSI trunk rotation
- CONTRA hip rotation
Pubic symphysis dysfunction - Tx

Shotgun technique
Nutation - define; occurs w/what pelvic tilt?
- Sacral flexion
- Happens w/posterior pelvic tilt
Upslip of innominate - definition

Vertical shear of entire innominate - ASIS & iliac crest are UP in comparison to opposite side
Upslip of innominate - L dysfunction - 5
- L crest up
- L ASIS up
- L leg shorter in supine
- L leg shorter in long sitting
- (+) Standing flexion test on L
Anterior Innominate Rotation - define

U/L - PSIS is up & anterior/ ASIS is down when compared to opposite side
Anterior Innominate Rotation - L dysfunction - 6
- L crest up
- L ASIS down
- L leg longer in supine
- L leg shorter in long sitting
- (+) standing flexion test on L
- (+) long sitting test on L
Posterior Innominate Rotation - define

U/L - PSIS is down & posterior/ ASIS is up when compared to opposite side
Posterior Innominate Rotation - L dysfunction - 6
- L crest down
- L ASIS up
- L leg shorter in supine
- L leg longer in long sitting
- (+) standing flexion test on L
- (+) long sitting on L
Forward/backward sacral torsion - define
- Sacral sulcus deep (in prone)
- Sacral inferior lateral angle (ILA) posterior & down (opposite side)
Forward/backward sacral torsion - Ex
- Sacral sulcus deep on R
- Sacral ILA posterior & down on L
Test for Anterior/Posterior Innominate Rotation - 2
- Standing flexion test
- Long sitting test
Test for Forward/Backward sacral torsion - 1

Sitting/flexion test
Anterior torsion of innominate - activities that precipitate dysfunction - 4
- Squatting/lilting/lowering
- Pregnancy
- Hip at 90° w/axial loading
- Golfing/batting/tennis
Posterior torsion of innominate - activities that precipitate dysfunction - 4
- Vertical thrust onto extended LE
- Sprint starting position
- Fall onto ischial tuberosity
- U/L standing
Sacral dysfunction - activities that precipitate dysfunction - 5
- Long-term postural abnormalities
- Fall onto sacrum/coccyx
- Carrying a load during ambulation
- Trauma during childbirth
- Loss of balance during ambulation
- Sitting combined w/rotation & lilting
Muscle Energy Technique (MET) - As pt does isometric contraction, following physiologic changes occur - 2
- Duration of isometric contraction
- Golgi tendon organ activation --> inhibition of agonist muscles
- Reflexive reciprocal inhibition -->t antagonistic muscles
- Duration - 3–5 s
Anterior Innominate Rotation
- Tight mms - 2
- Weak mms - 2
- Tight mms = Rectus femoris; Illiacus
- Weak mms = Hamstrings; Glute maxjQuery1101019419496764927158_1482943118948?
Anterior Innominate Rotation - Stretching

jQuery110108226209777922857_1485191832315???
Anterior Innominate Rotation - Muscle Energy Technique (MET)
- What mm is used?
- Hamstrings
Posterior Innominate Rotation
- Tight mms - 2
- Weak mms - 2
- Tight mms = Hamstrings; Glute max???
- Weak mms = Rectus femoris; Illiacus
Posterior Innominate Rotation - Muscle Energy Technique (MET)
- What mm is used?
- Rectus femoris
Posterior Innominate Rotation - Stretching

????
What innominate rotation is being treated by MET? How?

MET for correcting L innominate ‘posterior’ rotation using rectus femoris: blocking attempted extension of flexed L knee
What innominate rotation is being treated by MET? How?

MET for correction of R innominate ‘anterior’ rotation: using gluteus maximus/Hamstrings by blocking attempted R hip extension
What test is pictured? What is tested?
- Distraction test @ SI
- Pt supine, PT applies cross-arm P to both ASIS
What test is pictured? What is tested?
- Thigh thrust
- SI dyfunction
- Pt supine w/hip flexed 90
- PT applies posteriorly directed force through femur
What test is pictured? What is tested?
- Gaenslen’s test
- Pt supine near edge of table w/1 leg hanging over edge/Other leg flexed toward chest
- PT applies P to both hanging leg & flexed leg
What test is pictured? What is tested?
- Compression test @ SI
- Pt side-lying, w/affected side up
- Hips @ 45 flexion/Knees @ 90 flexion
- PT applies vertically downward force to ASIS
Sacral thrust - describe
- Pt prone
- PT applies force vertically downward to center of sacrum
Name test; Describe; (+)
- Goldthwait's Test
- Differentiates bet lumbar vs. SIJ
- Pt supine; PT fingers bet lumbar SP; Passive SLR
- (+) for SIJ = pain present prior to opening of lumbar segments (1-30 deg)
- (+) for lumbar - pain present bet 30-60 deg
