Positioning the Pelvis

---

1.  Possible causes for posterior pelvic tilt include all of the following EXCEPT: Low abdominal/trunk tone Seat depth is too shallow Limited range of motion, particularly limited hip flexion Extensor thrust

2.  The top of the lower portion of a biangular back is placed at the: ASIS PSIS Ischial tuberosities Greater trochanters

3.  The following strategy may reduce a pelvic posterior tilt: Attach the hip belt at a 60 degree angle Anti-thrust seat Open seat to back angle All of the above

4.  Which hip belt angle pulls the pelvis into a posterior tilt? 30 degrees 45 degrees 60 degrees 90 degrees

5.  Which hip belt angle maintains a neutral pelvic tilt? 30 degrees 45 degrees 60 degrees 90 degrees

6.  Austin demonstrates a windswept posture. This is defined as: Bilateral adduction Bilateral abduction One leg is adducted and one leg is abducted Pelvis is rotated

7.  Austin's legs can be moved to a neutral position, but this could lead to: Posterior pelvic tilt Anterior pelvic tilt Pelvic rotation Pelvic obliquity

8.  Interventions for extensor thrust for posterior pelvic thrust include: Anterior knee blocks; dynamic back Change position in space if thrust is caused by tonic labyrinthine reflex Increase hip and knee flexion, hip abduction and ankle dorsiflexion All of the above

9.  A possible cause of anterior pelvic tilt is ________________. Kyphosis Lateral scoliosis Rotational scoliosis Lordosis

10.  Which of the following might be used to accommodate a fixed pelvic obliquity? Adjust the hip belt to pull back on the forward side Wedge under the high side Position the hip belt over the lap to pull down the high side Knee blocks
