Pelvic Drop Table Technique Pelvic Drop Table Technique is a synthesis of concepts and ideas from Thompson, Gonstead, and Activator chiropractic techniques. Chiropractic procedures from each of these techniques are blended together to create a fluid, easy to learn method for analyzing and adjusting the pelvis. Students will come away with a deeper appreciation for integration of chiropractic techniques.

2 NEGATIVE DERIFIELD Scenario #1 Posterior Rotation of the Sacrum Left SI Fluid Motion LEFT SI FLUID MOTION Apply a firm continuous pressure S-I, P-A, and medial-to-lateral through the joint plane into the table. If both legs lengthen simultaneously, then the sacroiliac joint on the side tested is fixed. This test indicates sacroiliac joint fixation for any one of the six primary pelvic listings. INITIAL DERIFIELD LEG CHECK Perform the Initial Derifield Leg Check. If Negative Derifield is presented, continue with the Negative Derifield Protocol. Initial Derifield Leg Check has been adapted from: Fuhr, AW, et al. Activator methods chiropractic technique, second edition, St. Louis: Mosby-Elsevier,

3 ANKLE INVERSION Typically ankle inversion is noted on the side of the short leg in the prone extended position. (Potential left short leg). If ankle inversion is on the side opposite the short leg in the prone position, it may be due to a previous ankle inversion sprain. Ask the patient about their past history. Note the side of the short leg in the prone extended position (left short leg). If the left short leg in the prone extended position stays short when flexed to 90 degrees, the initial leg check indicates Left Negative Derifield. Negative Derifield confirms a θy-axis misalignment of the pelvis EX Ilium, Posterior Rotation of the Sacrum, IN Ilium, or Anterior Rotation of the Sacrum. Next, perform the Left θy- Axis Segmental Dysfunction Test for the Pelvis. Thompson Educational Workshops. The thompson technique reference manual. Elgin, IL:

4 To perform the Left θy-axis Segmental Dysfunction Test for the Pelvis, instruct the patient to lock the knee on the side tested. Next, extend the lower extremity at the acetabular hip to its end range. And finally, extend the hip into resistance a few degrees to engage the sacroiliac joint on the side of involvement. Note the left short (indicator) leg in the prone extended position. Left θy-axis Segmental Dysfunction Test Left Posterior Rotation of the Sacrum If the reactive (indicator) leg stays short in the prone extended position and the leg on the side tested (left) becomes long when the legs are flexed to 90 degrees, pressure test for Left Posterior Rotation of the Sacrum and left EX Ilium. 4

5 Pressure test* for Posterior Rotation of the Sacrum. Apply a Posterior-to-Anterior and Medial-to Lateral Pressure. To pressure test for Left Posterior Rotation of the Sacrum, apply a posterior-toanterior and medial-tolateral pressure on the left sacral ala just lateral to the first and second sacral tubercles. *Haas M, Peterson D, Panzer D, Rothman E, Solomon S, Krein R, et al.

6 Post-Adjustment Leg Check: The legs should become even in the prone extended and 90 flexion positions after adjusting for Left Posterior Rotation of the Sacrum. LEFT SI FLUID MOTION Post Ajustment: The leg on the side tested should now lengthen while the leg on the opposite side remains stationary indicating that the sacroiliac joint on the side tested is now freely moveable. Left SI Fluid Motion The foot of the stationary leg may demonstrate moderate toe-out foot flare, which is considered a normal variant.

Perform the Left θy-axis Segmental Dysfunctional Test for the Pelvis. If the side tested flexed leg becomes long, Articular pressure test for P-L and Left EX Ilium. If the legs become even in the extended and flexed positions Upon articular pressure testing for P-L, adjust P-L. The legs should be even in the extended and flexed positions upon post-adjustment Derifield leg check, and post-adjustment Right SI Fluid Motion should now be freely moveable. 6

7 NEGATIVE DERIFIELD Scenario #2 EX Ilium Walking in Place: Instruct the patient to line the tips of their shoes on the yellow line. Next, instruct the patient to place their fingertips on the wall to stabilize themselves while they walk in place. Walking in Place: Instruct the patient to close their eyes and walk in place for 30 seconds. After 30 seconds, instruct the patient to stop. Next, observe the position of their feet. Look for relative toe-in and toeout foot flare. Also, note whether one foot is in front of the other. If one foot is in front of the other, and also has relative toe-in foot flare; this may indicate potential EX Ilium on that side. 7

8 EX ILIUM ANECDOTAL FINDINGS The patient may experience sciatic-like pain down the back of the thigh. Copyright Howard Pettersson 1999 EX ILIUM VISUALIZATION Observe the contour of the gluteal musculature that extends about two inches laterally from the PSIS. This strip of muscle, normally about two inches wide, appears narrow and hunched compared to the opposite side. Copyright Howard Pettersson 1999 Right Gluteal Hunching Note the right gluteal hunching and the left gluteal flattening. Gluteal hunching is a visual finding for EX Ilium. Right Left Copyright 2015 Howard Pettersson 8

9 EX ILIUM TRIGGER POINTS The gluteus medius trigger points may be tender upon palpation. One is located two inches, and the other four inches lateral of the PSIS, respectively. These trigger points may be present even though the problem may be an IN ilium on the opposite side. Copyright Howard Pettersson 1999 Right SI Fluid Motion RIGHT SI FLUID MOTION Apply a firm continuous pressure S-I, P-A, and medial-to-lateral through the joint plane into the table. If both legs lengthen simultaneously, then the sacroiliac joint on the side tested is fixed. This test indicates sacroiliac joint fixation for any one of the six primary pelvic listings. INITIAL DERIFIELD LEG CHECK Perform the Initial Derifield Leg Check. If Negative Derifield is presented, continue with the Negative Derifield Protocol.

If ankle inversion is on the side opposite the short leg in the prone position, it may be due to a previous ankle inversion sprain. Ask the patient about their past history. Note the side of the short leg in the prone extended position (left short leg). If the left short leg in the prone extended position stays short when flexed to 90 degrees, the initial leg check indicates Left Negative Derifield. Negative Derifield confirms a θy-axis misalignment of the pelvis EX Ilium, Posterior Rotation of the Sacrum, IN Ilium, or Anterior Rotation of the Sacrum. Next, perform the Right θy- Axis Segmental Dysfunction Test for the Pelvis. Thompson Educational Workshops. The thompson technique reference manual. Elgin, IL:

11 To perform the Right θy-axis Segmental Dysfunction Test for the Pelvis, instruct the patient to lock the knee on the side tested. Next, extend the lower extremity at the acetabular hip to its end range. And finally, extend the hip into resistance a few degrees to engage the sacroiliac joint on the side of involvement.

If the legs become even in the extended and flexed positions Upon articular pressure testing for Right EX Ilium, adjust Right EX Ilium. The legs should be even in the extended and flexed positions upon post-adjustment Derifield leg check, and post-adjustment Right SI Fluid Motion should now be freely moveable. 13

14 NEGATIVE DERIFIELD Scenario #3 IN Ilium IN ILIUM ANECDOTAL FINDINGS The patient may experience inguinal area/groin pain. If the pain is severe it may radiate a short distance into the anterior-medial thigh. In some cases testicular pain may also be present. Copyright Howard Pettersson 1999 Walking in Place: Instruct the patient to line the tips of their shoes on the yellow line. Next, instruct the patient to place their fingertips on the wall to stabilize themselves while they walk in place. 14

15 Walking in Place: Instruct the patient to close their eyes and walk in place for 30 seconds. After 30 seconds, instruct the patient to stop. Next, observe the position of their feet. Look for relative toe-out and toein foot flare. Also, note whether one foot is behind the other. If one foot is behind the other, and also has relative toe-out foot flare; this may indicate potential IN Ilium on that side. IN ILIUM VISUALIZATION Observe the contour of the gluteal musculature that extends about two inches laterally from the PSIS. This strip of muscle, normally about two inches wide, appears flattened compared to the opposite side. Copyright Howard Pettersson 1999 Left Gluteal Flattening Note the right gluteal hunching and the left gluteal flattening. Gluteal flattening is a visual finding for IN Ilium.
