Sacroiliac dysfunction
Sacroiliac dysfunction is shown to be the common causes of back pain in sports and non sport peoples.
Motions of sacrum on ilia
On transverse axis
- Nutation
- Counter-nutation
On oblique axis (Physiological/Forward torsion)
- Right on Right
- Left on Left
On oblique axis (Non-physiological/Backward torsion)
- Right on Left
- Left on Right
Dysfunctions and Treatment
Left on Left dysfunction
Deep sulci | Right |
Shallow sulci | Left |
ILA posterior | Left |
L5 rotation | ERS-Right |
Seated flexion test | Right |
Sphinx test | Symmetry |
Lordosis | Increased |
Short leg | Left |
MET procedure
- Patient position: SIMS position on Right side.
Right on Left dysfunction
Deep sulci | Left |
Shallow sulci | Right |
ILA posterior | Right |
L5 rotation | FRS-Left |
Seated flexion | Right |
Sphinx test | Asymmetry (Right base shallow) |
Lordosis | Decreased |
Short leg | Right |
MET procedure
- Patient position: Side lying on left side.
- Flexing the top leg and extending the lower leg.
- Ask the patient lift the leg (Horz abd) against the therapist resistance isometrically for 10 secs. Then ask the patient to relax and lower the leg towards the floor. The muscle energy technique is repeated for 3 - 5 times to correct the R-L SI dysfunction.
