Answer 12

angle of anteversion

Question 13

Question 13 According to William Hamilton, the smaller the angle of inclination and the longer the femoral neck, the greater range of [fill in] a dancer is likely to have in his/her/their natural structure.

Answer 16

Answer 1:
ilium
ischium
pubis

Answer 2:

ischium

Question 17

Question 17 Why might a dancer be able to turn out (lateral femoral rotation) more with his/her/their pelvis tilted anteriorly? (Katarina’s Response)

Answer 17

A dancer would experience greater turnout because it reduces the grip of the iliofemoral and pubofemoral ligaments.

Feedback: Yes, when the pelvis is tipped anteriorly the Y ligament is relaxed. The Y ligament limits external rotation.

Question 18

Question 18 What is the anatomical definition of turn out (lateral femoral rotation)? (Katarina’s Response)

Answer 18

Anatomically, the greater trochanter moves toward the back and closer to the ischial tuberosity during turnout or lateral femoral rotation.

Question 19

Question 19 Why do dancers often have a greater range of hyperextension at the iliofemoral joint than non-dancers? (Katarina’s Response)

Answer 19

For dancers, the Y ligament becomes stretched out so they can have a larger range of motion during hyperextension compared to the general population.

Question 20

What are three reasons that could account for a dancer having difficulty achieving a “neutral” pelvis? (Katarina’s Response)

Answer 20

1. Weak core/abs
2. Shortened or tight lower back muscles
3. Short or tight quads
