Anatomy/Biomechanics
Sacral torsion occurs in this plane.
What is the oblique plane?
The PSIS, ASIS, and iliac crest is superior on R side.
What is R Side upslip?
This test involves the clinician pushing the ASIS apart in order to compress the SI joint.
What is ASIS Gapping/SI Compression Test?
What is latissimus dorsi?
This leg length measurement measures from ASIS to medial malleolus
What is a structural/anatomical leg length measurement?
The point at which there is a change of direction at the sacrum.
What is the Inferior Lateral Angle?
Supine-to-sit test. R leg is longer in supine and becomes shorter in sitting.
What is anterior iliac rotation?
For this test, the patient is position in hip flexion, external rotation, and abduction.
An individual with an inferior PSIS, superior ASIS, and superior pubic tubercle. What pelvic dysfunction is likely present?
Posterior rotation.
Movement of the sacrum involving anterior rotation at the base and posterior rotation at the apex.
What is nutation?
The superior and wider portion of the sacrum.
What is the base of the sacrum?
This type of pelvic dysfunction is usually "self correcting"
This test involves the patient bending forward while eliminating the influence of the hamstrings on pelvic stability.
During Gillet test, patient's PSIS on involved side drops. Is this a positive or negative test?
Negative.
Muscles contribute to this form of stability of the pelvic girdle.
Force closure.
During trunk extension, this movement occurs at the sacrum (in the initial phase).
What is nutation?
Outflares normally present with this type of rotation.
What is posterior rotation?
Position of patient for Gaenslen's test.
Pt is supine with one knee to chest and other leg off table in hyperextension.
During standing flexion test, the patient's Right PSIS moves superiorly faster than the left PSIS. What does this indicate?
Hypomobility of the SIJ
This ligament runs from the ischial tuberosity to the dorsal SI lig/sacrum.
What is the sacrotuberous ligament?
The shape of the innominates and sacrum contribute to stability.
What is form closure?
PSIS, iliac crest, and ischial tub is superior with ASIS and pubic tubercles slightly inferior.
What is an upslip with anterior rotation?
This test involves compression at the ASIS in an upward & medial 45 degree angle.
What is the squish test?
This pelvic dysfunction is likely present in a patient who has a more medially displaced ASIS and laterally displaced PSIS on the Right side
What is a R side inflare?
This muscle energy technique can be used to "fix" a superior pubic symphysis dysfunction & involves isometric abduction and adduction.
