Right SI Fluid Motion - what does it mean when the right leg lengthens and the left leg remains stationary
Right SI joint is freely moveable
Right SI Fluid Motion - what does it mean when both legs lengthen
Right SI fixation
Left SI Fluid Motion - what does it mean when the left leg lengthens and the right leg remains stationary
Left SI joint is freely moveable
Left SI Fluid Motion - what does it mean when both legs lengthen simultaneously
Left SI fixation
What test indicates SI joint fixation for any one of the primary pelvic listings
SI Fluid Motion
What does it mean when the foot of the stationary leg demonstrates moderate toe-out foot flare
It’s a normal variant
Where is spongy edema palpable on a PI ilium
posterior - superior margin of SI joint
Where is point tenderness on a PI ilium
superior aspect of the SI joint
Upon static palpation of a PI ilium the PSIS palpates where
relatively inferior to the PSIS on the opposite side
Upon static palpation of an AS ilium, the PSIS palpates where
relatively superior to the PSIS on the opposite side
Upon static palpation of a PI ilium the ischial tuberosity palpates where
anterior relative to the opposite side
Upon static palpation of a AS ilium the ischial tuberosity palpates where
posterior relative to the opposite side
Where is spongy edema on an AS ilium
posterior-inferior margin of the SI joint
Where is point tenderness on an AS ilium
inferior aspect of the SI joint
