What tests are performed for Y axis motion palpation
Seated SI Axial Rotation
Seated Lumbopelvic Lateral Bending
Leg Fanning
Right Ipsilateral Axial Rotation - what side do you stand on
left
Right Ipsilateral Axial Rotation - what hand is your contact hand
right
Right Ipsilateral Axial Rotation - what is your SCP
right PSIS
Right Ipsilateral Axial Rotation - which direction will the PSIS go (medial or lateral)
medial
Right Ipsilateral Axial Rotation - what do you compare the right side to
left ipsilateral axial rotation
Right Ipsilateral Axial Rotation - how can you tell which side is fixed
if one PSIS does not glide medially when compared to the opposite side is fixed
Is the fixed side typically an IN or EX ilium
EX ilium

lateral
Right Contralateral Axial Rotation - what do you compare the right side to
Left Contralateral Axial Rotation
Right Contralateral Axial Rotation - how can you tell what side is fixed
when comparing the two contralateral sides, the one that does not move laterally is fixed
Seated Sacroiliac Axial Rotation - Right or Left Ipsilateral Fixation indicates IN or EX ilium

IN ilium
Seated Lumbopelvic Lateral Bending - Right or Left Ipsilateral Fixation indicates IN or EX ilium
EX ilium
Seated Lumbopelvic Lateral Bending - Right or Left Contralateral Fixation indicates IN or EX ilium
IN ilium
Leg Fanning - Right or Left Abduction Fixation indicates
posterior rotation of the sacrum or
EX ilium
Leg Fanning - Right or Left Adduction Fixation indicates
IN ilium
When PSIS palpates more medial (or closer) to the second sacral tubercle is it an IN or EX misalignment
IN Misalignment
If it is an IN Misalignment will the PSIS palpate more medial (closer to) or lateral (further away) to the second sacral tubercle
medial
When the spongy edema is located along the entire anterior margin of the SI joint is it an IN or EX misalignment
IN misalignment
If it is an IN misalignment where will the spongy edema be located
entire anterior margin of the SI joint
Can the anterior margin of the SI joint be palpated
no
Can the edema from an IN misalignment be palpated
no, it’s on the anterior side of SI joint
If it is an EX misalignment where will the spongy edema be located
posterior margin of SI articulation
When the spongy edema is located on the entire posterior margin of the SI articulation is it an IN or EX misalignment
EX misalignment
If it is an EX Misalignment will the PSIS palpate more medial (closer to) or lateral (further away) to the second sacral tubercle
lateral (further away)
If the PSIS is palpated more lateral (further away) from the second sacral tubercle is it an IN or EX misalignment
EX misalignment
If there is an IN misalignment will the gluteal muscle be flattened or narrowed and hunched
flattened
If the gluteal muscle is flattened is it an IN or EX misalignment
IN misalignment
If there is an IN misalignment the toe-out foot flare may be found on the side of IN or EX ilium and place stress on the medial knee or ace tabular hip
IN ilium and acetabular hip
If there is a toe-out foot flare on the side of IN ilium and stressing the acetabular hip is it an IN or EX misalignment
IN misalignment
If there is an EX misalignment will the gluteal muscle be flattened or narrowed and hunched
narrow and hunched
If the gluteal muscle is narrow and hunched is it an IN or EX misalignment
EX misalignment
If there is an EX misalignment the toe-out foot flare may be found on the side of IN or EX ilium and place stress on the medial knee or ace tabular hip
EX ilium and medial knee
If there is a toe-in foot flare on the side of EX ilium and stressing the medial knee is it an IN or EX misalignment
EX misalignment
The sympysis rotates to which side - IN or EX
IN
Only one of the ilia are fixed/subluxated - the other is in a position of compensatory alignment. What side is fixed - spinous rotation or body rotation
side of posterior body rotation
The gluteus medius trigger points may be tender upon palpation. One is located 2” lateral and the other 4” lateral of the PSIS. These trigger points may be present even though the problem may be an IN ilium on the opposite side. Does this indicate an IN or EX misalignment
EX misalignment
The patient may experience sciatic-like pain down the back of the thigh. Is this IN or EX misalignment
EX misalignment
The patient may experience inguinal/groin pain that may be exacerbated when the patient rises from the seated position. If the pain is severe it may radiate a short distance into the anterior-medial thigh. In some cases testicular pain may be present. Is this IN or EX misalignment
IN misalignment (check for tight/weak priformis and external rotators)
