� <strong>Stiles</strong>’ AGR for LOWER HALF OF THE BODY:<br />

� For the lower half <strong>of</strong> the body start with a standing flexion test. Are the lumbar<br />

paravertebral muscles symmetrical? Does one PSIS ride superior?<br />

� Next perform a seated flexion test. Does the lumbar spine show asymmetry <strong>of</strong><br />

motion and/or muscle volume? Does one PSIS ride superior? Is the PSIS shift<br />

stronger for seated than standing flexion? If so look to the lumbar spine,<br />

innominates, and/or sacrum for the SGR.<br />

� If the lumbar paravertebral muscles demonstrate asymmetry in both standing<br />

and seated flexion use the same test as that performed for the thoracic spine<br />

(sidebending from the shoulder). Is one side <strong>of</strong> the lumbar spine restricted? Can<br />

you localize a segment that has a diagonal hard end-feel when the regional<br />

restriction is maximized?<br />

� Now use the same sidebending to test the sacrum. Is sacrum restricted? Did one<br />

PSIS ride superior in the seated flexion test? Evaluate sacral mechanics.<br />

� If the PSIS rides superiorly on the same side in both standing and seated<br />

flexion, it suggests that the pelvis may be the area <strong>of</strong> greatest restriction.<br />

Likewise compression from the shoulder may lateralize restriction to the pelvis.<br />

Evaluate for the nature <strong>of</strong> the restriction.<br />

� If the standing flexion PSIS shift is stronger than the seated, look to the leg on<br />

that side. An additional clue that it might be the leg: diffuse unilateral<br />

paravertebral muscle tightness.
