LUMBO-PELVIC: TESTING OF POSTERIOR ILIAL ROTATION
The patient is lying prone on a firm surface. The therapist is standing to the right side of the patient. The therapist places his fingers of his left hand under the patient’s left ASIS (for mobilization). The therapist’s right hand in cupped in such a manner that the heel is placed over the patient’s right posterior ilium (for stabilization) and the index or long fingertip is placed over the patient’s left SI joint (for palpation).
The therapist pulls up (away from the table) on the patient’s left ASIS while applying an equal downward counterforce on the patient’s right ilium and palpating the patient’s left SI joint.
Normal motion is detected as a slight upward separation of the patient’s left ilium from the sacrum in the absence of symptoms. Hypomobility is suspected when there is reduced or absent motion. Hypermobility is suspected when there is excessive motion or guarding. A posteriorly rotated ilium is suspected when there is reduced motion which is associated with symptoms over that SI joint or pelvic region.
* This procedure should be repeated for right posterior ilial rotation. The therapist should reverse his hand placement and should stand to the patient’s left side.
* A comparison should be made between the patient’s left and right SI joints before a dysfunction is determined.
