Test #2 SIJ

Question 1

What is the Sacroiliac Joint (SI Joint)?

Answer 1

The point of intersection between
the spine and the lower extremity

Question 2

What are the functions/responsibilities of the sacrum?

Answer 2

• Provides stability
• Transmits the weight of the body from the vertebral column to the pelvic region

Question 3

How many muscles attach to the osseous structures of the hip?

Answer 3

28

Question 4

What are the functions of the SIJ?

Answer 4

• shock absorption
• transfer of bodyweight between the vertebral column and the lower extremity

Question 5

What are the movements of the SIJ?

Answer 5

nutation and counternutation

Question 6

Nutation

Answer 6

when the sacrum moves forward/anteriorly and down

Question 7

Counternutation

Answer 7

when the sacrum moves backward/posteriorly and up

Question 8

Triad for SIJ diagnosis

Answer 8

(+) history
(-) BCE for lumbar spine
(+) provocation test(s)

Question 9

SIJ provocation tests

Answer 9

• Dorsolateral
• Ventromedial
• Thigh Thrust (Ostgaard)
• Sacral Thrust
• Gaenslen

Question 10

Dorsolateral test

Answer 10

patient = supine
examiner = either side
- cross arms and place on both ASIS
- apply a dorsolateral force to the ASIS
- hold for 3 mins unless they feel pain before the 3 mins; if so terminate the test

Question 11

What is a positive dorsolateral test?

Answer 11

if unilateral pain is provoked in the abdomen, buttock or the leg

Question 12

Ventromedial test

Answer 12

patient: side lying with affected area up
examiner: behind patient
- compress the iliac crest by applying a ventromedial force
- hold for 3 minutes unless patient experiences pain prior to the 3 min

Question 13

What is a positive ventromedial test?

Answer 13

reproduction of symptoms

Question 14

Ostgaard (Thigh Thrust)

Answer 14

patient = supine
examiner = opposite side
- Flex the patient’s hip to 90 degrees

• Place your hand on the
  patient’s sacrum just medial to the PSIS on the test side
• Apply an axial force through the femur
• If the first side is not painful the other side should be tested in the same manner

Question 15

What is a positive Ostgaard (Thigh Thrust) test?

Answer 15

reproduction of pain

Question 16

Sacral Thrust

Answer 16

patient = prone
examiner = either side
- Clinician delivers an anterior directed thrust directly over the
patient’s sacrum

• apply 3-5 thrusts

Question 17

What is a positive sacral thrust test?

Answer 17

reproduction of pain

Question 18

Gaenslen’s Test

Answer 18

patient = supine
examiner = testing side
- Bring the patient’s opposite leg into full hip and knee flexion while the patient maintains the hip closest to them in an
extended position of the side of the table

• Apply overpressure to the flexed extremity, then to both
  extremities simultaneously
• If this is not painful, perform in the same manner on the
  opposite side

Question 19

What is a positive Gaenslen’s Test?

Answer 19

reproduction of pain
